Abstract: Retrosternal goiter prevalence is 5 to 40 per cent according to classifications in goiter

series. Goiters with mediastinal extension were reported to be related with higher cancer rates. In

our study, we aimed to investigate whether cancer incidence increased in retrosternal goiters

compared with the cervical ones. Three hundred and ninety consecutive patients, who had surgery

because of retrosternal goiter in Istanbul University Medical Faculty Department of General

Surgery between 2005 and 2015 were included in the study (Group 1). Control group included 880

patients who had surgery because of nontoxic multinodular goiter in the same period (Group 2).

Preoperative ultrasonography (USG) was performed to each patient. Fine-needle aspiration biopsy

was performed in suspicious nodules and results were recorded. Carcinomas in histopathological

examination were classified as intrathorasic and extrathorasic. Diagnostic rates of USG results

were compared with histopathologic cancer results. Papillary carcinoma was diagnosed in 76

patients with retrosternal goiter (19%) and in 200 patients in the control group (22%). No

statistically significant difference was detected between groups regarding the tumor rates (P >

0.05). One hundred and forty-four tumoral foci were detected in 76 patients with papillary

carcinoma in retrosternal goiter patients. Three hundred and seventy tumoral foci were detected in

200 patients with papillary carcinoma in the control group. In the retrosternal goiter group, 104

carcinoma lesions of 144 papillary carcinomas were intrathorasic (72%). No statistically

significant difference was detected between intrathorasic (2.1 +/- 1 cm) and extrathorasic regiones

(1.9 +/- 0.8 cm) regarding the tumor size P > 0.05. When patients with and without cancer in the

retrosternal goiter group were compared regarding familial thyroid cancer history, radiation to the

neck, and cervical adenopathy, no statistically significant difference was detected. Cancer

incidence of retrosternal goiters was not higher than that of the cervical ones. Yet, cancer foci of

retrosternal goiters were commonly located in the intrathorasic area and were not detected with

USG. Depending on these findings, we suggest that all retrosternal goiters should be surgically

treated.

Abstract: OBJECTIVES: Pancreatic surgery has been greatly influenced by the advent of laparoscopic surgery and increasing experience in its performance and by advances in techniques and surgical devices. This study aimed to represent two centers' initial experiences in laparoscopic

distal pancreatic surgery.

METHODS: This study was a bi-centric study including 30 patients undergoing distal

pancreatectomy for pancreatic disorders. All the patients were operated on from November 2006

to November 2013 in Turkey and Spain.

RESULTS: Laparoscopic spleen-preserving distal pancreatectomy was performed in 9 patients,

laparoscopic distal pancreatectomy was performed in 14 patients, laparoscopic enucleation was

performed in 4 patients, and single-incision laparoscopic distal pancreatosplenectomy with

splenectomy was performed in 3 patients.

CONCLUSIONS: Laparoscopic distal pancreatectomies for pancreatic disorders are feasible and

safe procedures if performed by experienced laparoscopic surgeons.

Abstract: Background: Reoperative neck surgery is technically more demanding because of the

presence of scar tissue and distorted anatomy. We aimed to investigate the magnetic probe-guided

excision of nonpalpable neck lesions in patients with previously operated neck compartments.

Methods: This study included 9 patients with recurrent/persistent thyroid carcinoma,

recurrent/persistent hyperparathyroidism with previously operated neck compartments. The

pathologic lesions were localized by ultrasonography, and magnetic tracer (0.2 mL, iron oxide)

was injected directly into the pathologic lesions. Careful dissection was carried out following the

area of maximum magnetic activity until the nonpalpable lesions were identified and excised.

Result: All neck lesions were removed in 9 patients. The median count from lesion was

significantly higher than values from lesion bed (background activity; (9900/5 seconds vs 250/5

seconds, P < .001). During follow-up, all patients had negative ultrasonography. Conclusion:

Magnetic probe-guided technique could provide access to nonpalpable lesion localization in

centers without readily available access to nuclear medicine facilities.

Abstract: Objective: Primary hyperparathyroidism (PHPT) is often seen in conjunction with an

underlying thyroid disorder. Imaging methods that are used to localize the parathyroid adenoma

also detect associated thyroid nodules and thyroid cancer. The aim of this study was to detect the rate of thyroid cancer identified while performing parathyroidectomy and thyroidectomy in

patients with PHPT.

Material and Methods: Files of all patients who were operated for PHPT and who underwent

simultaneous thyroidectomy were analyzed. Data regarding parathyroid pathology, surgical

procedures, indications of thyroid surgery, and pathology results were retrospectively recorded.

The indications for thyroid surgery included presence of suspicious thyroid nodules in

ultrasonography, increase in size of thyroid nodules in follow-up ultrasound, or presence of

suspicious thyroid fine needle aspiration biopsy (FNAB) findings. Rates of thyroid cancer

detection were investigated according to definite pathology reports.

Results: Eighty-three patients who underwent parathyroidectomy with a diagnosis of PHPT with

concurrent thyroidectomy in Department of General Surgery, Istanbul University Istanbul Faculty

of Medicine were included in the study. Eighteen patients were male (22%) and 65 were female

(78%). The median age was 53 (18-70) years. The primary indication for parathyroidectomy was

primary hyperparathyroidism in all patients. The thyroid procedures applied in addition to

parathyroidectomy were lobectomy + isthmusectomy in 29 patients (35%), bilateral subtotal

thyroidectomy in 20 patients (24%), bilateral total thyroidectomy in 23 patients (28%), and total

thyroidectomy on one side and near total thyroidectomy to the other side in 11 patients (13%). The

only indication for thyroidectomy was the presence of thyroid nodules until 2000 (20 patients,

24%). Indications in the remaining 63 patients included the presence of multiple nodules that

cannot be followed up by ultrasonography in 25 patients (30%), presence of a suspicious nodule

on ultrasonography in 33 patients (40%), growth in nodule size in 2 patients (2%), and detection of

suspicious findings on FNAB in 3 patients (4%). Five patients (6%) were diagnosed with papillary

thyroid cancer, four of whom were micropapillary cancer.

Conclusion: Imaging methods performed to localize the pathological parathyroid gland for a

diagnosis of PHPT are useful in estimating other accompanying pathologies. Presence of thyroid

nodules should be evaluated before all parathyroid procedures, and if the nodule has an indication

for surgery, thyroid surgery should be considered at the same operation with parathyroid surgery.

Abstract: AIM: Single-port laparoscopic surgery (SILS) has become increasingly popular during

the last decades. This prospective study was undertaken to evaluate the feasibility of single-port

laparoscopic splenectomy compared with conventional multiport laparoscopic splenectomy.

MATERIALS AND METHODS: Between February 2, 2009 and August 29, 2011, a total of 40

patients with the diagnosis of immune thrombocytopenic purpura were included to study. Patients

were alienated into two groups according to the procedure type including SILS and conventional

multiport splenectomy. RESULTS: There were 19 patients in group 1, and 21 in group 2.

Operative time was significantly shorter in group 1 versus group 2 (112.4 +/- 13.56 vs 71.2 +/-

18.1 minutes, respectively, P < 0.05). One patient in group 1 had converted to laparatomy due to

preoperative bleeding. Postoperative pain analyses (VAS Score) revealed superiority of SILS in the early post-operative days (P < 0.05). CONCLUSIONS: SILS splenectomy is a safe and

effective alternative to standard laparoscopic splenectomy.

Abstract: BACKGROUND: Although, there are studies in the literature having shown the

feasibility and safety of laparoscopic adrenalectomy, there are still debates for tumour size and the

requirement of the minimal invasive approach. Our hypothesis was that the use of laparoscopy

facilitates minimally invasive resection of large adrenal tumours regardless of tumour size.

Materials and Methods: Within 7 years, 149 patients underwent laparoscopic adrenalectomy at one

institution. The patients were divided into two study groups according to tumour size. Group 1

included patients with adrenal tumours smaller than 5 cm and group 2 included larger than 5 cm.

Patient demographics and clinical parameters, operative time, complications, hospital stay and

final pathology were analysed. Statistical analyses of clinical and perioperative parameters were

performed using Student's t-test and Chi-square tests. RESULTS: There were 88 patients in group

1 and 70 in group 2. There were no significant differences between study groups regarding patient

demographics, operative time, hospital stay, and complications. Estimated blood loss was

significantly higher in group 2 (P = 0.002). The conversion to open rate was similar between study

groups with 5.6% versus 4.2%, respectively. Pathology was similar between groups.

CONCLUSION: Our study shows that the use laparoscopy for adrenal tumours larger than 5 cm is

a safe and feasible technique. Laparoscopic adrenalectomy is our preferred minimally invasive

surgical approach for removing large adrenal tumours.

Abstract: Purpose: Laparoscopic techniques have allowed surgeons to perform complicated intraabdominal

surgery with minimal trauma. Single incision laparoscopic surgery (SILS) was

developed with the dim of reducing the invasiveness of conventional laparoscopy. In this study we

aimed to compare results of SILS cholecystectomy and three port conventional laparoscopic

(TPCL) cholecystectomy prospectively.

Methods: In this prospective study, 100 patients who underwent laparoscopic cholecystectomy for

gallbladder disease were randomly allocated to SILS cholecystectomy (group 1) or TPCL

cholecystectomy (group 2). Demographics, pathologic diagnosis, operating time, blood loss,

length of hospital stay, complications, pain score, conversion rate, and satisfaction of cosmetic

outcome were recorded.

Results: Forty-four SILS cholesystectomies (88%) and 42 TPCL cholecystectomies (84%) were

completed successfully. Conversion to open surgery was required for 4 cases in group 1 and 6

cases in group 2. Operating time was significantly longer in group 1 compared with group 2 (73

minutes vs. 48 minutes; P < 0.05). Higher pain scores were observed in group 1 versus group 2 in

postoperative day 1 (P < 0.05). There was higher cosmetic satisfaction in group 1 (P < 0.05).

Conclusion: SILS cholecystectomy performed by experienced surgeons is at least as successful,

feasible, effective and safe as a TPCL cholecystectomy. Surgeons performing SILS should have a

firm foundation of advanced minimal access surgical skills and a cautious, gradated approach to

attempt the various procedures. Prospective randomized studies comparing single access versus

conventional multiport laparoscopic cholecystectomy, with large volumes and long-term followup,

are needed to confirm our initial experience. (ClinicalTrials.gov Identifier: NCT01772745.)

Abstract: Visceral artery aneurysms are rare and important vascular entities due to the quarter of

all cases presented as surgical emergency. Nevertheless, splenic artery aneurysm (SAA) is the

most common visceral and third most common intra-abdominal artery aneurysm after aorta and

iliac artery. SAA accompany splenic vein aneurysm because arteriovenous fistula communication

between them is a very rare entity. Location and size of the SAA determine the likelihood of

rupture. Women of child-bearing age who have SAAs are at particularly high risk of death as a

result of aneurysm rupture and should be treated with elective repair. Herein, we report a case of a

splenic artery and vein aneurysm with arteriovenous fistula in a 25-year-old young female patient

who presented with left upper quadrant pain. Diagnosis was established by computerized

tomography angiogram. The patient underwent laparoscopic resection of splenic artery and vein,

as well as with splenectomy. Laparoscopic therapy for SAA should be considered for the patient

with a low periprocedural morbidity at experienced surgical clinics.

Abstract: Background: Current indications for adrenalectomy include functional adrenal tumors

and potentially malignant tumors based on imaging studies. We evaluated the effectiveness of

magnetic resonance imaging (MRI) in obtaining a correct preoperative diagnosis.

Method: Fifty-three patients with nonfunctional adrenal lesions were analyzed. Indications for

adrenalectomy of nonfunctional adrenal lesions included >6 cm in size and <= 6 cm in size with

atypical characteristics on MRI. Lesions with a size of >6 cm, local invasion, irregular margins,

and chemical-shift imaging that demonstrated no loss of signal intensity on out-of-phase images

were considered suspected of malignancy.

Results: Adrenal lesions of >6 cm in size exhibited an 80-fold increased prediction of malignancy

(OR: 80; 95% CI 7.8-813), whereas irregular margins and local invasion exhibited a 45-fold (OR:

45; 95% CI 6.4-312.5) and a 12-fold (OR: 12; 95% CI 4.6-30.6) increased occurrence of

malignancy, respectively. The loss of signal intensity did not affect the prediction of malignancy.

Conclusion: The rate of unnecessary tumor resections that are <6 cm in size can be decreased by

performing adrenal biopsies in selected cases or by short-term follow-up to prevent the

insufficiency of imaging techniques. (C) 2012 Surgical Associates Ltd. Published by Elsevier Ltd.

Abstract: Introduction: A novel single port access (SPA) cholecystectomy approach is described

in this study. We have designed a randomised comparative study in order to elucidate any possible

differences between the standard treatment and this novel technique. Materials and Methods:

Between July 2009 and March 2010, 140 adult patients with gallbladder pathologies were enrolled

in this multicentre study. Two surgeons (RV and UB) randomised patients to either a standard

laparoscopic (SL) approach group or to an SPA cholecystectomy group. Two types of trocars were

used for this study: the TriPort (TM) and the SILS (TM) Port. Outcomes including blood loss,

operative time, complications, length of stay and pain were recorded. Results: There were 69

patients in the SPA group and 71 patients in the SL group. The mean age of the patients was 43.2

(17-77) for the SPA group and 42.6 (19-70) for the SL group. The mean operative time was 63.9

min in the SPA group and 58.4 min in the SL group. For one patient, the SPA procedure was

converted to a standard laparoscopic technique and to open approach in the SL group.

Complications occurred in eight patients: Five seromas (two in the SPA group) and three hernias

(one in the SPA group).The mean hospital stay was 38.5 h in the SPA group and 24.1 h in the SL

group. Pain was evaluated and was 2 in the SPA and 2.9 in the SL group, according to the visual

analogue scale (VAS) after 24 h (P < 0.001). The degree of satisfaction was higher in the SPA

group (8.3 versus 6.7). Similar results were found for the aesthetic result (8.8 versus 7.5). (P <

0.001). Conclusion: Single-port transumbilical laparoscopic cholecystectomy can be feasible and

safe. When technical difficulties arise, early conversion to a standard laparoscopic technique is

advised to avoid serious complications. The SPA approach can be undertaken without the expense

of additional operative time and provides patients with minimal scarring. The cosmetic results and

the degree of satisfaction appear to be significant for the SPA approach.

Abstract: Objective: Most laparoscopic surgeons have attempted to reduce incisional morbidity

and improve cosmetic outcomes by using less and smaller trocars. Single incision laparoscopic

splenectomy is a new laparoscopic procedure. Herein we would like to present our experiences.

Material and Methods: Between January 2009 and June 2009, data of the 7 patients who

underwent single incision laparoscopic splenectomy were evaluated retrospectively.

Results: There were 7 patients (5 females and 2 males) with a mean age of 29.9 years. The most

common splenectomy indication was idiopathic thrombocytopenic purpura. Single incision

laparoscopic splenectomy was performed successfully in 6 patients. In one patient the operation

was converted to an open procedure.

Conclusion: With surgeons experienced in minimally invasive surgery, single incision

laparoscopic splenectomy could be performed successfully. However, in order to demonstrate the

differneces between standard laparoscopic splenectomy and SILS splenetomy, prospective

randomized comparative studies are required.

Abstract: Background: Chronic pain and related complications reported after the use of

perforating fixation devices in hernia surgery have led to the use of tissue sealants. Fibrin sealant

is a feasible option for mesh fixation; however data on cyanoacrylate glues are limited. Methods:

32 Sprague-Dawley rats were divided into two groups and a 1.5 cm abdominal wall defect was

created on each animal. The lesions were then repaired with 2 x 2 cm polypropylene meshes, fixed

with n-butyl-cyanoacrylate in the first group and with polypropylene sutures in the second group.

The rats were sacrificed on the 21st and 42nd days. The presence of infection, recurrence, and

abdominal adhesions were evaluated, followed by biomechanical testing and histological

examination. Results: No mesh infection or hernia recurrences were recorded. There was no

statistically significant difference between neither the adhesion scores nor the mean broken

pressure of the two groups. Cyanoacrylate sealing was found equivalent to suturing in terms of

tissue ingrowth, fibrosis, inflammatory infiltration, abscess formation, and necrosis. Furthermore,

cyanoacrylate resulted in less foreign body reaction. Conclusions: Mesh fixation by cyanoacrylate

may be considered as an alternative to suture fixation.

Abstract: Background: Transumbilical single incision laparoscopic surgery (SILS) offers

excellent cosmetic results and may be associated with decreased postoperative pain, reduced need

for analgesia, and thus accelerated recovery. Herein, we report the first transumbilical single

incision laparoscopic pancreatectomy case in a patient who had renal cell cancer metastasis on her

pancreatic corpus and tail.

Methods: A 59-year-old female who had metastatic lesions on her pancreas underwent

laparoscopic subtotal pancreatectomy through a 2-cm umbilical incision.

Results: Single incision pancreatectomy was performed with a special port (SILS port) and

articulated equipment. The procedure lasted 330 minutes. Estimated blood loss was 100mL. No

perioperative complications occurred. The patient was discharged on the seventh postoperative

day with a low-volume (20mL/clay) pancreatic fistula that ceased spontaneously. Pathology result

of the specimen was renal cell cancer metastases.

Conclusion: This is the first reported SILS pancreatectomy case, demonstrating that even

advanced surgical procedures can be performed using the SILS technique in well-experienced

centers. Transumbilical single incision laparoscopic pancreatectomy is feasible and can be

performed safely in experienced centers. SILS may improve cosmetic results and allow

accelerated recovery for patients even with malignancy requiring advanced laparoscopic

interventions.

Abstract: Background: Most of the laparoscopic surgeons have been attempting to reduce

incisional morbidity and improve cosmetic outcomes by using fewer and smaller ports. Singleincision

laparoscopic surgery (SILS) is a new laparoscopic procedure. Herein we would like to

present our experiences.

Patients and Methods: Between January 2009 and October 2009, data of the 32 patients who were

operated through SILS are evaluated prospectively. There were 22 females and 10 males with a

mean age of 45.1 +/- 14.8 years. Ten splenectomies for idiopathic thrombocytopenic purpura, 16

cholecystectomies for acute cholecystisis or asymptomatic gallstones, 3 appendectomies for acute

apendicitis, one distal pancreatosplenectomy for Renal Cell Cancer metastases, 1 adrenalectomy

for Conn Syndrome and 1 case of liver resection for hepatic adenoma were carried out. The most

common splenectomy indication was idiopathic trombocytopenic purpura, cholecystectomy

indication was acute cholecystitis (n = 8), and asymptomatic cholelithiasis (n = 8), appendectomy

indication was acute appendicitis, distal pancreatosplenectomy indication was renal cell cancer

metastases, adrenalectomy indication was Conn syndrome and liver resection indication was left

hepatic mass in between segments 1 and 2. SILS was carried out successfully in 31 patients. Only

in 1 patient conversion was required owing to bleeding.

Results: All procedures were carried out through a 2-cm umbilical incision. There was no

mortality and morbidity recorded.

Conclusions: In experienced hands of minimally invasive surgeons, SILS incision laparoscopic

surgery could be carried out successfully in a wide range of surgical operations. However, to be

able to show the differences between Standard laparoscopic surgery and single SILS, prospective

randomized comparative studies are required.

Abstract: Background: Obesity and visceral fat are thought to be the most important factors

influencing the technical difficulty during open and laparoscopic surgery. The authors aimed to

investigate the effect of retroperitoneal fat mass on surgical outcomes in patients undergoing laparoscopic adrenalectomy. Patients and methods: This prospective study included 51

consecutive patients who underwent lateral transabdominal laparoscopic adrenalectomy. Body

mass index (BMI) and retroperitoneal fat area (RFA)/adrenal mass area (AMA) ratio were

calculated. Results: There was a positive correlation between BMI and operating time and

postoperative complications and hospital stay. According to 2-way analysis of variance, only

RFA/AMA ratio (P = .0001) was found to significantly correlate with operating time, whereas

BMI did not significantly correlate with operating time (P = .51). In patients with high BMI, high

RFA indicated longer operating time and higher complication rate, whereas low RFA was

associated with significantly shorter operating time and decreased risk of complications.

Conclusion: Retroperitoneal fat mass is a more useful parameter than BMI for predicting the

surgical outcomes of laparoscopic adrenalectomy.

Abstract: Background Although some studies have compared laparoscopic and hand-assisted

laparoscopic splenectomy (HALS) in splenomegaly cases, no study has analyzed the differences

between HALS and open splenectomy (OS). This study aimed to compare the HALS and OS

techniques in splenomegaly cases.

Methods This prospective study included 27 patients undergoing splenectomy for splenic

disorders at the Department of General Surgery, Istanbul Medical Faculty between February and

October 2007. Open splenectomy was performed for 14 patients and HALS for the remaining 13

patients.

Results The end points compared included incision length, operative time, intraoperative blood

loss, postoperative drain output and duration, postoperative pain scores, length of postoperative

hospitalization, and perioperative complications. The authors found benefits of HALS over OS for

incision length, postoperative pain score, postoperative drain output and duration, and hospital

stay. The main advantages of the HALS technique over OS were less postoperative pain (p =

0.0002), shorter hospital stay (p = 0.004), and shorter abdominal incision (p = 0.012).

Conclusions For splenomegaly, HALS significantly facilitates the surgical procedure and reduces

the hospital stay while maintaining the advantages of OS such as tactile sense as well as easy and

atraumatic manipulation of enlarged spleens.

Abstract: It is not clear whether nonfunctional adrenal incidentaloma (NFA) increases the risk of

atherosclerosis and metabolic syndrome or whether this type of adrenal tumor has been found

more frequently in patients with cardiometabolic risk factors. We aimed to determine the effects of

NFA on cardiometabolic risk factors and endothelial function and to compare the patients with a

1:1 cardiometabolic risk factor matched control group.

Thirty-five patients with NFA were studied, and 35 body mass index-, age-, and sex-matched

subjects were regarded as group 2 controls. Thirty-five cardiometabolic risk factors-matched

subjects were then regarded as group 3 controls.

Patients with NFA had significantly lower flow-mediated dilation (FMD)-a parameter for

endothelial function-measurements compared with groups 2 and 3 (7.1 +/- A 2.9% vs. 12.9 +/- A

3.8% and 13.5 +/- A 4.5%; P < 0.02). Frequency of metabolic syndrome was also significantly

higher in NFA patients than in control groups 2 and 3 (31.4, 5.7, and 20.0%, respectively; P <

0.05). Age (Odds Ratio [OR] = 2.9), total cholesterol (OR = 2.3), and presence of adrenal

incidentaloma (OR = 10) were significant independent predictors of lower FMD (P < 0.05 for all).

Patients with NFA have increased prevalence of metabolic syndrome and impaired endothelial

function compared with 1:1 cardiometabolic risk factor-matched controls.

Abstract: Single incision laparoscopic procedures are presumed to be as a step towards pure

natural orifice transluminal endoscopic surgery. However, loss of requirement of any perforation

of visceral organ and endoscopic equipment make this technique more popular and easily

performable. Herein we report two splenectomy cases where single incision surgery (SILS)

technique was performed.

Two females of 28 years old and 22 years old with the diagnoses of ITP underwent single incision

laparoscopic splenectomy. Preoperatively with the receival of steroid therapy, thrombocyte counts

were 92,000/m(3). A 2-cm umbilical incision was used for the placement of three (5 mm) trocars.

One 5-mm videoscope (30A degrees) and roticulated laparoscopic dissector/grasper were the main

tools during surgical procedure. Spleen was removed with a plastic removal bag through the

umbilical trocar incision. The whole procedure ended in 110 and 150 min in both cases without

any problem.

Two patients were discharged on third and second postoperative days with the thrombocyte counts

of 174,000/m(3) and 400,000/m(3), respectively.

Although there were some procedures performed with single incision technique like cholecystectomy, prostatectomy, and partial nephrectomy, as far as we are concerned this is the

first report about laparoscopic splenectomy performed with single incision surgery technique.

Abstract: Background: Concomitant thyroid nodules are the most common reason for falsepositive

ultrasonography (US) results in primary hyperparathyroidism. The aims of this

prospective clinical Study were to evaluate false-positive US results according to the

characteristics of concomitant thyroid nodules and to determine which characteristics of thyroid

nodules are important.

Study design: This prospective Study included 120 consecutive patients with primary

hyperparathyroidism. The patients were divided into 2 groups according to preoperative US

results. Group I consisted of 32 patients with false-positive US results and group 2 consisted of 88

patients with true-positive US results.

Results: The risk for false-positive US result was increased 25-fold for patients with parathyroid

adenoma weight of more than 500 mg (odds ratio [OR], 25; 95% confidence interval [CI], 8.6-

74.5), 75-fold for more than I posteriorly located thyroid (OR, 75; 95% CI, 19.3-293.4), 358-fold

for the presence of exophytic thyroid nodules (OR, 358; 95% Cl, 42.3-3036), and 423-fold for the

presence of posteriorly located thyroid nodules (OR, 423; 95% Cl, 49-3662).

Conclusion: Although there was no particular characteristic of concomitant thyroid nodules that

contributes to false-positive US results, the posteriorly located thyroid nodules were the strongest

Correlate for the false-positive US results to other features. (C) 2009 Elsevier Inc. All rights

Abstract: Secondary hyperparathyroidism (sHPT) is common in patients with chronic renal

failure. Bilateral cervical exploration is optimal for patients with sHPT. The aims of this clinical

trial are to evaluate the feasibility of video-assisted subtotal parathyroidectomy as an alternative

surgical treatment for sHPT.

This prospective study included 12 consecutive patients with sHPT. Surgical indications included

a high intact parathormone level, enlarged parathyroid glands, high bone turnover and conditions

refractory to medical treatment of hypercalcemia and hyperphosphatemia.

All patients underwent minimally invasive video-assisted subtotal parathyroidectomy and transcervical

thymectomy. Four cervical glands were found in all patients and intrathymic glands were

identified in three (25%) patients.

Minimally invasive video-assisted subtotal parathyroidectomy offers an alternative method, and

this technique can be performed safely for sHPT.

Abstract: BACKGROUND: Hypocalcemia Caused by transient or definitive hypoparathyroidism

is the most frequent complication after thyroidectomy. We aimed to compare the impact of

incidental parathyroidectomy and serum vitamin D(3) level on postoperative hypocalcemia after

total thyroidectomy (TT) or near total thyroidectomy (NTT).

PATIENTS: Two hundred consecutive patients with nontoxic multinodular goiter treated by TT

and NTT were included prospectively in the present Study. Group I (n = 49) consisted of patients

with a postoperative serum calcium level <= 8 mg/dL, and group 2 to = 151) had a postoperative

serum calcium level greater than 8 mg/dL. Patients were evaluated according to age, preoperative

serum 9 25-hydroxy vitamin D (25-OHD) levels, postoperative serum calcium levels, incidental

parathyroidectorny, and the type of thyroidectomy.

RESULTS: Patients in group I (In = 49) were hypocalcemic, whereas patients in group 2 (n = 151

were normocalcemic. Preoperative serum 25-OHD) levels in group I were significantly lower than

in group 2 (P < .001). The incidence of hypoparathyroidism was significantly higher following TT

(13.5%) than following NTT (2.5%) (P <.05). The risk For postoperative hypocalcemia was

increased 25-fold for patients older than 50 years, 28-fold for patients with a preoperative serum

25-OHD level less than 15 ng/mL, and 71-fold for patients Who underwent TT. Incidental

parathyroidectomy (lid not have an impact on postoperative hypocalcemia. The highest risk of

postoperative hypocalcemia was found in the patients with all of the above variables.

CONCLUSIONS: Age, preoperative low serum 25-OHD, and TT are significantly associated with

postoperative hypocalcemia. Patients with advanced age and low preoperative serum 25-OHD

levels should be placed on calcium or vitamin D supplementation after TT to avoid postoperative

hypocalcemia and decrease hospital stay. (C) 2009 Elsevier Inc. All rights reserved.

thyroidectomy and may occur even in the hands of experienced thyroid surgeons. We aimed to

investigate the clinical relevance of incidental parathyroidectomy and to determine which risk

factors are important for it.

Patients: Four hundred and forty consecutive patients with non-toxic multinodular goitre treated

by total and near-total thyroidectomy were included prospectively in the present study. Patients in

group 1 (n = 48) had inadvertent resection of parathyroid gland, whereas patients in group 2 (n =

392) did not have parathyroid glands removed.

Results: There was a positive correlation between the incidental parathyroidectomy and total

thyroidectomy (r(s) = 0.519, p = 0.0001), and thyroid pathology (r(s) = 0.338, p = 0.0001) and

intrathyroid parathyroid locations. Incidental parathyroidectomy did not have an impact on

postoperative hypocalcemia. The risk for incidental parathyroidectomy was increased 13-fold for

patients who underwent total thyroidectomy (OR: 13.7; 95% CI:4.08-46.05), 4-fold for patients

with substernal goitre (OR: 4.1; 95% CI:1.1-14.3).

Conclusions: Total thyroidectomy, thyroid pathology, and intrathyroid parathyroid locations are

risk factors for incidental parathyroidectomy. All established risk factors for incidental

parathyroidectomy are also risk factors for postoperative hypocalcemia. Incidental

parathyroidectomy during thyroid surgery may be a potential complication. (C) 2008 Surgical

Abstract: Background: Laparoscopic adrenalectomy has become the gold standard in most

patients with adrenal tumors. It is unclear; however, at what size an adrenal neoplasm should be

resected by means of an open or a laparoscopic approach. The aim of the present study was to

compare the outcomes of laparoscopic adrenalectomy for large tumors with smaller tumors.

Methods: A prospective study of patients who underwent adrenalectomy during the period 2006-

2009 was undertaken. The patients were divided into 2 groups according to the tumor size. Group

1 (n = 29) consisted of patients presenting tumors smaller than 5 cm in diameter; group 2 (n = 31)

consisted of patients with tumors larger than 5 cm in diameter.

Results: Two of the 29 tumors in group 1 (6.8%) were malignant at final histology. However, 11

of the 31 tumors in group 2 (35.4%) were malignant. There were no significant differences

between operating time and complications of groups 1 and 2. The intra-operative blood loss was

significantly lower in group 1 than in group 2.

Conclusion: Laparoscopic adrenalectomy is a reasonable procedure for selected large adrenal

tumors when a complete resection is technically feasible and there is no evidence of local

invasion. (c) 2009 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

Abstract: Hypothesis: The detection of suspected malignant thyroid nodules by ultrasonography

is associated with thyroid gland volume and tumor size.

Design: Prospective clinical trial.

Setting: A tertiary referral center.

Patients: Three hundred sixty-five patients with a multinodular goiter with coexistent dominant

nodules.

Main Outcome Measures: The correlation between thyroid gland volume and tumor size and the

detection of suspected malignant thyroid nodules by ultrasonography. The incidence of thyroid

carcinoma inside and outside the dominant nodules and thyroid gland volume and tumor size in

suspected or unsuspected malignant thyroid nodules by ultrasonography were determined.

Receiver operating characteristic analysis was used to identify the cutoffs of the tumor size and

thyroid gland volume.

Results: One hundred thyroid carcinomas were found in 69 (18.9%) patients. Forty-one of these

carcinomas were inside the dominant nodule, whereas 59 were outside the dominant nodule. Only

9 of the 59 thyroid carcinomas outside the dominant nodules were suspected of being malignant

by ultrasonography. Thyroid gland volume less than 38 mL and tumor size larger than 7mm had

48-fold (odds ratio, 48; P <.001) and 21.5-fold (odds ratio, 21.5; P <.001) increased rates,

respectively, of detecting suspected malignant thyroid nodules by ultrasonography.

Conclusions: Thyroid gland volume and tumor size were significantly associated with detection of

suspected malignant thyroid nodules by ultrasonography. Small thyroid gland volume was

associated with detection of suspected malignant thyroid nodules in multinodular goiters.

Abstract: In this era of modern technologies, laparoscopic adrenalectomy is a gold standard

surgical treatment for benign adrenal lesions. However, being aware of its difficulties and their

managements is a very important issue for the surgeons who are interested in minimal invasive

surgery. In this article, we are presenting a case of a 57-year-old woman who has undergone

laparoscopic left adrenalectomy and in the third postoperative month, had an acute gastric volvulus requiring surgical open treatment. To the best of our knowledge, this report is the first

article about a gastric volvulus case after left laparoscopic adrenalectomy.

Abstract: Although the sensitivity of preoperative localization techniques is high for solitary

parathyroid adenomas, negative imaging study results are inevitable. The weight and location of

the parathyroid adenoma may contribute to the negative results. We aimed to study the impact of

adenoma weight and ectopic location of the parathyroid adenoma on ultrasonography and

sestamibi scan results. The patients were divided into two groups according to adenoma location.

Group 1 consisted of 36 patients with ectopic location, and group 2 consisted of 149 patients with

normal location. Parathyroid adenoma weight and the results of imaging studies were determined

in all patients. Of 185 patients operated on for hyperparathyroidism, 36 (19.4%) had ectopic

parathyroid glands. There was a positive correlation between adenoma weight and positive

imaging studies, whereas ectopic location did not correlate with negative imaging study results.

There was no significant difference between the ectopic adenoma ratio of patients with negative

and positive imaging study results. The weight of the ectopic parathyroid adenoma was

significantly lower in patients with negative imaging study results than in patients with positive

imaging study results (p = 0.001). According to the analysis of variance, patients with higherweight

adenomas have positive imaging study results irrespective of ectopic location. For both

normal and ectopic adenoma locations, adenoma weight was found only to be a factor that

positively influences imaging study results.

Abstract: Background. Preoperative preparation of the patient with Graves' disease (GD) is

crucial to avoid intraoperative or postoperative complications associated with anesthesia or

surgery. We aimed to evaluate thyroid blood flow and microvessel density in patients with GD

according to antithyroid drug (ATD) treatment, preoperatively.

Method. Forty-three patients were divided into two groups according to the ATD type. Patients in

group 1 (n = 25) were treated with methimazole, whereas patients in group 2 (n = 18) were treated

with propylthiouracil, preoperatively. Blood flow through the thyroid arteries was measured by

color flow Doppler ultrasonography. The microvessel density (MVD) was assessed

immunohistochemically and via Western blot analysis using the level of CD-34expression in

thyroid tissue.

Results. There was a positive correlation between blood loss and thyroid volume (r(s) = 0.953, P =

0001) and blood flow (r(s) = 0.720, P = .0001) and CD-34 expression (r(s) = 0.331, P = .03) and

MVD (r(s) = 0.442, P = .003). No correlation was observed between ATD type and thyroid

vascularity. In patients with longer treatment duration before operation, thyroid vascularity was

significantly lower relative to patients with shorter treatment durations. According to. logistic

regression analysis, longer treatment duration had a 142-fold decreased rate of intraoperative

blood loss independent of ATD type.

Conclusion. Preoperative ATD treatment duration may predict intraoperative blood loss during

thyroidectomy. Longer treatment duration might be useful in reducing intraoperative bleeding,

allowing better visualization and preservation of the nerves and parathyroid glands.

Abstract: Background: Although the sensitivity of sestamibi scanning (MIBI) is high in patients

with solitary parathyroid adenomas, negative sestamibi scan results are inevitable. The exact

mechanism of visualization of abnormal and hyperfunctioning parathyroid tissue is not yet clear.

The aims of this clinical study were (1) to evaluate positive and negative sestamibi scan results

with regard to adenoma weight and oxyphil cell content and (2) to compare the effects of adenoma

weight and oxyphil cell content on the results of sestamibi scanning.

Patients: The patients were divided in 2 groups according to their sestamibi scan results. Group I

consisted of 27 patients with positive sestamibi scan results, and group 2 consisted of 20 patients

with negative sestamibi scan results. Parathyroid adenoma weight and oxyphil cell content were

determined in all patients.

Results: The weight and oxyphil cell content of the parathyroid adenomas in the patients of group

I were significantly higher than those in the patients of group 2 (P = .001). An adenoma weight >

600 mg and an oxyphil cell content > 20% increased the rate of obtaining a positive sestamibi scan

result 10- and 4-fold, respectively.

Conclusions: Both adenoma weight and oxyphil cell content were found to significantly correlate

with positive sestamibi scan results. In patients with high-weight adenomas, adenoma weight was

the most significant factor in obtaining positive MIBI scan results, whereas in patients with low

adenoma weights, high oxyphil cell content was the most significant factor in obtaining positive

MIBI scan results. (c) 2008 Excerpta Medica Inc. All rights reserved. Accession Number: WOS:000251968300008

Abstract: Adrenal cysts are very rare lesions, usually asymptomatic or without characteristic

symptoms. They are classified as pseudocysts, endothelial cysts, epithelial cysts or parasitic cysts.

Although pseudocysts are reported to be the most common clinically recognized adrenal cysts in

surgical series, endothelial cysts are more common in autopsy series. We studied 15 consecutive

patients with adrenal cysts who underwent surgical resection at our institution from 1990 to 2005.

Of 15 patients with adrenal cysts, 10 had pseudocysts, 3 epithelial cysts, 1 an endothelial cyst and

1 a parasitic cyst. In conclusion, a better understanding of cystic adrenal masses is necessary to

recognize true adrenal cysts and differentiating them from adrenal carcinoma or adenoma by

demonstrating the foci of cystic or degenerative changes. Copyright (c) 2008 S. Karger AG, Basel.

Abstract: Background and Aim: Ulcerative colitis is a chronic inflammatory disease of the colon

and rectum. Although the precise etiology of ulcerative colitis remains unknown, it is believed to

involve an abnormal host response to endogenous or environmental antigens, genetic factors, and

oxidative damage. The aim of the present study was to investigate whether heme oxygenase-1

(HO-1) induction by octreotide could protect against oxidative and inflammatory damage from

induced colitis.

Methods: Rats received octreotide 50 mu g/kg per day intraperitoneally for 5 days before 2,4,6

trinitrobenzene sulfonic acid (TNBS) solution administration and for 15 days following TNBS

solution administration. Rats were killed on day 21, and colonic malondialdehyde (MDA) levels,

glutathione (GSH) levels and HO-1 expression were measured. Nuclear factor (NF)-kappa B and

HO-1 expression was evaluated by immunohistochemical examination of the colonic tissue.

Results: Rats with TNBS-induced colitis had significantly increased colonic MDA levels and HO-

1 expression in comparison to the control group. Octreotide treatment was associated with

increased HO-1 expression and GSH levels, but decreased MDA levels. Histopathological

examination revealed that the intestinal mucosal structure was preserved in the octreotide-treated

group. In addition, treatment with octreotide significantly increased HO-1 expression and

decreased NF-kappa B expression by immunohistochemistry when compared to the TNBSinduced

colitis group.

Conclusion: Octreotide appears to have protective effects against colonic damage in TNBSinduced

colitis. This protective effect is, in part, mediated by modification of the inflammatory

response and the induction of HO-1 expression.

Abstract: The detection of nonpalpable recurrent thyroid carcinoma has increased due to the use

of imaging techniques in time. This report is to investigate whether preoperative injection of a

radiotracer under ultrasound guidance is useful in nonpalpable recurrent thyroid carcinoma. The

neck of two patients with recurrent thyroid carcinoma was scanned with the probe to localize the

area of maximal radioactivity allowing appropriate location of the incision over the lesion. After

the lymph nodes were removed, radioactivity was measured in the lesion bed to confirm the

success of the dissection. In conclusion, the radio-guided nonpalpable lesion localization

technique can be performed safely for the detection and excision of metastatic foci.

Abstract: Wandering spleens are rarely encountered ectopic localizations of the spleen. They are

either congenital or acquired owing to the lack of or weakening of the major splenic ligaments.

Herein, we present a female patient who was admitted to our hospital with the complaint of abdominal distension and chronic constipation. We performed laparoscopic splenectomy in this

case for the diagnosis of a wandering spleen located in the right upper quadrant. The accepted

treatment of this pathology is splenopexy unless there is no necrosis of the organ. Minimal

invasive procedures should be the primary choice in the treatment of this entity.

Abstract: Background/Aims: Dieulafoy's lesions are uncommon sources of upper gastrointestinal

tract bleeding. Endoscopists must be aware of these lesions when evaluating patients with upper

gastrointestinal tract bleeding.

Methodology: The aim of this study is to analyze the results of active bleeding or recurrently

bleeding Dieulafoy's lesions treated either by endoscopic injection therapy (EIT) or endoscopic

band ligation (EBL). Fifteen patients who had active bleeding due to Dieulafoy's lesions were

evaluated retrospectively with respect to demographic properties, comorbidities, endoscopic

therapy procedures, and the success rate of the procedure:

Results: The incidence of Dieulafoy's lesions was 4.5% in all cases of upper gastrointestinal tract

bleeding. Among the 15 patients there were nine men and six women with a median age of 52

years (25-84 years). Eleven of these lesions were located in the stomach, two were in the

duodenum, and two were in the distal esophagus. Eight patients were initially treated by EIT and

seven patients had EBL therapy. There was no recurrent bleeding in any of the patients treated

with EBL, but five patients (62.5%) treated with EIT bled again and were treated secondarily with

EBL. Two of these patients required surgical intervention and one died on the 15th day of surgery

due to myocardial infarction. No endoscopyrelated complications were detected.

Conclusions: Endoscopic methods should be the first choice in treating bleeding Dieulafoy's

lesions. Both EIT and EBL are successful methods for achieving initial hemostasis. However, EIT

therapy has a higher re-bleeding rate. EBL is a safe and effective method for the treatment of

bleeding Dieulafoy's lesions.

Abstract: Context: Although some endocrine surgeons administer Lugol solution to decrease

thyroid gland vascularity, there is still not an agreement on its effectiveness.

Objective: The aims of this clinical trial are to evaluate thyroid blood flow and microvessel

density in patients with Graves' disease who received Lugol solution treatment preoperatively.

Design: This was a prospective clinical trial.

Setting: This clinical trial took place at a tertiary referral center.

ethod: Thirty-six patients were randomly assigned to receive either preoperative treatment with

Lugol solution (group 1, n = 17) or no preoperative treatment with Lugol solution (group 2, n =

19).

Main Outcome Measures: Blood flow through the thyroid arteries of patients with Graves' disease

was measured by color flow Doppler ultrasonography. The microvessel density (MVD) was

assessed by immunohistochemical and Western blot analysis of the level of expression of CD-34

in thyroid tissue. The weight and blood loss of the thyroid gland were measured in all patients.

Results: The mean blood flow, MVD, CD-34 expression, and blood loss in group 1 patients were

significantly lower than those in group 2 patients. There was a negative correlation between Lugol

solution treatment and blood flow (rs = 0.629; P = 0.0001), blood loss (rs = -0.621; P = 0.0001),

MVD (rs = -0.865; P = 0.0001), and CD-34 expression (rs = -0.865; P = 0.0001). According to

logistic regression analysis, Lugol solution treatment resulted in a 9.33-fold decreased rate of

intraoperative blood loss.

Conclusion: Preoperative Lugol solution treatment decreased the rate of blood flow, thyroid

vascularity, and intraoperative blood loss during thyroidectomy.

Abstract: Background: Preoperative determination of the accessory spleen still is a major factor

in the failure of both laparoscopic and conventional techniques. This study aimed to evaluate the

practicability and efficacy of a handheld gamma probe in identifying accessory spleens at the

initial intervention.

Methods: This study evaluated 17 patients undergoing laparoscopic splenectomy attributable to

benign hematologic disorders. All the patients had preoperative ultrasonography, computed

tomography (CT) scan, and nuclear scintigraphic examination of the abdominal cavity to assess

the size of the spleen, and to determine the existence of the accessory spleen or spleens. For all the

patients, a handheld gamma probe count was used intraoperatively as an adjuvant method to

define the presence and location of the accessory splenic tissue. Control nuclear scintigraphic

examinations of all the patients were performed 1 month after the surgical procedure.

Results: In two cases, intraoperatively accessory splenic tissue was detected by gamma probe, confirming the preoperative CT findings for the patients. One of these patients had three accessory

spleens, although preoperative CT scan showed only two of them. However, by the help of the

gamma probe, a third spleen located retroperitoneally was defined. For two patients, laparoscopic

exploration and handheld gamma probe count did not identify any accessory splenic tissue,

although preoperative CT scan indicated accessory spleens. For detecting accessory splenic tissue,

the sensitivities of the studied techniques were 0% for ultrasonography, 75% for CT scan, 0% for

preoperative nuclear scintigraphy, 75% for laparoscopic exploration, and 100% for perioperative

gamma probe examination.

Conclusion: Preoperative imaging methods for accessory spleen determination still have limited

benefits because of their limited sensitivity. Thus, the handheld gamma probe technique may be an

adjuvant method for laparoscopic exploration ensuring that no accessory splenic tissue is missed

during the initial surgical treatment of benign hematologic disorders.

Abstract: Graves' disease (GD) is a multifactorial disease that develops as a result of complex

interactions between genetic and environmental factors. The aim of our study is to determine the

frequency of cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) A/G and TG C/T exon 33

SNPs (Tg E33SNP) in GD and to evaluate the relation between recurrence and these

polymorphisms. A total of 187 subjects, including 97 previously treated GD patients and 90 age

and gender matched control subjects were studied. We examined the relationship between the A/G

and C/T polymorphism and various clinical and laboratory variables among patients with GD. TT

genotype frequency in the GD patients was significantly higher than the controls. Number of

recurrent patients was significantly higher in AG and GG carriers in comparison to AA carriers

(57% and 45% vs 14%,p = 0.0001). CTLA-4 AG genotype had an eightfold (OR: 8.050; 95 % CI:

2.87-22.5; p = 0.0001) and GG genotype had a sevenfold (OR: 7.025; 95% CI: 1.67-29.4; p =

0.007) increase in the risk of recurrence in the patients with GD. In conclusion, early interpretation

for definitive treatment procedures (i.e., radioactive iodine or surgery) may be considered in the

patients with G allielle and E33SNP of Tg gene is conformed the susceptibility to GD in a Turkish

population and having TT genotype increases the susceptibility to GD.

Abstract: Background: The aim of our study was to evaluate the oxidant/antioxidant status of

thyroid tissue in Graves' disease (GD) patients and to compare the results of GD thyroid tissue

with plasma of patients and healthy controls.

Methods: We studied 25 consecutive patients with GD hyperthyroidism who underwent surgical

treatment. The patients were divided into groups according to the duration of antithyroid drug

treatment, the type of antithyroid drugs used, the presence of ophthalmopathy, and recurrence after

a complete course of antithyroid drugs. Thiobarbituric acid-reacting substances (TBARS),

glutathione peroxidase (GPx) activity, superoxide dismutase (SOD) activity, and total thiol (t-SH)

content of tissue and plasma samples were determined.

Results: TBARS concentrations were found to be significantly increased in GD patients' plasma

compared with controls' plasma (0.1 +/- 0.02 nmol/mg protein vs. 0.062 +/- 0.01 nmol/mg

protein). Significantly decreased t-SH concentrations were measured in GD patients' plasma

compared with controls (8.26 +/- 1.9 nmol/mg protein vs. 13.03 +/- 3.3 nmol/mg protein). Tissue

TBARS, t-SH, GPx, and SOD measurements in GD patients indicated significantly increased

concentrations compared with the plasma levels of patients. Patients with shorter treatment

duration before the operation had significantly increased plasma and tissue TBARS and decreased

plasma and tissue t-SH concentrations. Patients on propylthiouracil treatment had significantly

lower plasma and tissue concentrations of TBARS than patients on methimazole. Patients with

recurrence had significantly higher plasma and tissue TBARS and lower plasma and tissue t-SH

concentrations than patients treated for the first time.

Conclusions: In euthyroid GD patients on antithyroid drugs, increased oxidative stress and a

compensatory increase in the antioxidant defense system are more prominent in thyroid tissue than

in plasma. Patients who relapsed had markers indicating increased oxidative stress. Thus, ongoing

autoimmunity may contribute to increased oxidative stress in GD patients, even in the euthyroid

state. (C) 2006 European Federation of Internal Medicine. Published by Elsevier B.V. All rights

Abstract: Purpose. The key to successful parathyroid surgery is accurate preoperative tumor

localization. This study investigates the use of ultrasound (US)-guided parathyroid fine needle

aspiration (FNA) as a confirmatory diagnostic method in patients with hyperparathyroidism

undergoing minimally invasive parathyroidectomy.

Methods. Patients were selected for minimally invasive parathyroidectomy based on the finding of

a single parathyroid adenoma identified with US and/or sestamibi scans and confirmation of the

suspected parathyroid lesion via FNA and parathyroid hormone (PTH) assay. The value of aspirate

obtained from the thyroid gland intraoperatively served as the negative control.

Results. A total of 56 tissue FNAs were performed in 27 patients. US detected masses suggestive

of parathyroid lesion in all 27 patients, and 31 US-guided FNAs were performed. No

complications related to the procedure were noted. Intraoperatively, FNA was performed in the

thyroids of 25 patients undergoing minimally invasive parathyroidectomy. Aspirates from lesions

subsequently confirmed as having developed from the parathyroid gland had a mean PTH level of

4,677 +/- 123 pg/ml (range, 3,600 - 5,000 pg/ml), which was significantly higher than thyroid aspirates, which yielded a mean PTH level of 48 +/- 7 pg/ml (range, 5-57 pg/ml). The sensitivity

of US and sestamibi scans in the detection of abnormal parathyroid glands was 88% and 77%,

respectively. The sensitivity of US-guided FNA in confirming the parathyroid origin of a lesion

was 100%.

Conclusion. US-guided FNA for PTH assay can be performed safely for the confirmation of

lesions identified with preoperative US for the selection of patients eligible for minimally invasive

parathyroidectomy. (c) 2006 Wiley Periodicals, Inc.

Abstract: Background In recent years, total or near-total thyroidectomy has emerged as a surgical

option to treat patients with multinodular goiter, especially in endemic iodine-deficient regions.

The aim of this study was to compare the complication rates of total and near-total thyroidectomy

in multinodular goiter and the incidence of thyroid cancer requiring radioactive iodine ablation

and completion thyroidectomy between groups.

Study design Patients with euthyroid multinodular goiter without any preoperative suspicion of

malignancy, history of familial thyroid cancer, or previous exposure to radiation were randomized

(according to a random table) to total thyroidectomy (group 1, n=104) and near-total

thyroidectomy leaving less than 2 g (group 2, n=112).

Results There were no persistent complications. The incidence of transient hypoparathyroidism in

group 1 (26%) was significantly higher than in group 2 (9.8%) (p < Ce0.001). The rate of

asymptomatic hypocalcemia in group 2 (7.4%) was lower than in group 1 (27%) (p < 0.001). The

incidence of papillary cancer was 9.6% in group 1 and 12.5% in group 2 (p > 0.05). None of the

patients underwent completion thyroidectomy before ablative therapy. Ten patients were found to

have the histological criteria for radioactive iodine ablation. Of these 10 patients, four were in

group 1 and six were in group 2 (p > 0.05).

Conclusion In conclusion, we recommend near-total thyroidectomy in multinodular goiter instead

of total or subtotal thyroidectomy. While near-total thyroidectomy and total thyroidectomy obviate

the need for completion thyroidectomy in incidentally found thyroid cancer, and while there is no

difference in the rate of recurrent laryngeal nerve palsy between the two methods, near-total

thyroidectomy causes a significantly lower rate of hypoparathyroidism compared to total

thyroidectomy.

Abstract: Background Thyroidectomies of hyperthyroidic patients are known to be more bloodspattered

than the operations performed for euthyroid nodular diseases and require careful

hemostasis. Our purpose was to evaluate the efficacy of the use of LigaSure in patients with

hyperthyroidism.

Materials and methods Between January 2004 and October 2005, 100 patients underwent total or

near-total thyroidectomy. Bipolar vessel ligation system (LigaSure) was the choice of modality for

hemostasis in half of these patients, and the conventional suture ligation technique was used for

the rest. The following data were evaluated non-randomized and prospectively in this study:

patients demographics, thyroid pathology, operative duration, presence of complications, and the

duration of the hospital stay. Comparisons of the data were evaluated by the Wilcoxon and chisquare

tests.

Results Among the patients of the LigaSure group, 14 patients were detected to have

hyperthyroidism (seven patients with Graves' disease and another seven patients with multinodular

toxic goiter), while 36 patients were found to be euthyroidic. The durations of the operation time

and of the hospital stay of the patients in the LigaSure group were significantly lower than the

conventional thyroidectomy group (p < 0.05). The complication rates of the LigaSure and

conventional thyroidectomy groups were 4 and 6%, respectively (p > 0.05).

Conclusions The use of LigaSure as an operative technique in the treatment of Graves' disease and

toxic goiter is a safe and effective modality that provides a shorter hospital stay and a shorter

operation time as well.

Abstract: Ulcerative colitis is a multifactorial inflammatory disease of the colon and rectum with

an unknown etiology. The present study was undertaken to investigate the effect of melatonin

administration on oxidative damage and apoptosis in 2,4,6-trinitrobenzene sulfonic acid (TNBS)-

induced colitis. Rats were divided into four groups as follows: Group 1 (n=8)-TNBS colitis; Group

2 (n=8)-melatonin, 10 mg/kg/day ip, for 15 days in addition to TNBS; Group 3 (n=8)-melatonin

alone, 10 mg/kg/day ip, for 15 days; and Group 4 (n=8)-isotonic saline solution, 1ml/rat ip, for 15

days (sham control group). Colonic myeloperoxidase (MPO) activities, malondialdehyde (MDA)

levels, and glutathione (GSH) levels are indicators of oxidative damage, while caspase-3 activities reveal the degree of apoptosis of the colonic tissue. In all TNBS-treated rats, colonic MPO activity

and MDA levels were found to be increased significantly compared to those in the sham group.

Colonic MPO activity and MDA levels were significantly lower in the melatonin treatment group

compared to TNBS-treated rats. GSH levels of colonic tissues were found to be significantly lower

in TNBS-treated rats compared to the sham group. Treatment with melatonin significantly

increased GSH levels compared to those in TNBS-treated rats. Caspas-3 activity of colonic tissues

was found to be significantly higher in TNBS-treated rats compared to the sham group. Treatment

with melatonin significantly decreased caspase-3 activity compared to that in TNBS-treated rats.

These results imply a reduction in mucosal damage due to anti-inflammatory and anti-apoptotic

effects of melatonin.

Abstract: Background: The widespread use of ultrasound, computerized tomography, and

magnetic resonance imaging has led to an increase in the number of incidental adrenal masses

identified. Asymptomatic incidentally discovered adrenal masses may indicate that subclinical

Cushing syndrome (SCS) is not uncommon. We aimed to evaluate the cardiovascular risk of

patients with SCS before and after surgery.

Methods: An autonomous cortisol-producing tumor was detected in 11 of 94 patients with adrenal

incidentaloma between 1995 and 2005. Twenty-eight patients suffering from classical Cushing

syndrome (CS) associated with unilateral adrenocortical adenoma, who were treated at our

department in the same period, served as a control group. Cardiovascular risk factors such as

blood pressure, body mass index, and lipid profile were evaluated before and 1 year after surgery.

Results: The frequency of hypertension (61% versus 63%), obesity (46% versus 55%), diabetes

mellitus (50% versus 36%), hypercholesterolemia (39% versus 36%), and low HDL cholesterol

(28% versus 36%) were not significantly different between CS and SCS patients, respectively.

Adverse cardiovascular risk profile improved 1 year after adrenalectomy in both groups, although

the changes were not significant with respect to body mass index, frequency of diabetes, and

hyperlipidemia in SCS patients. But frequency of systolic/diastolic hypertension decreased

significantly in this group.

Conclusions: These findings indicate that the increased incidence of cardiovascular risk factors

commonly observed in classical CS, is also present in SCS. Unilateral adrenalectomy does not

always lead to significant improvements in cardiovascular risk profile in SCS.

Abstract: Splenosis has been serious etiologic reason in the recurrence of benign hematologic

diseases after elective open or laparoscopic splenectomy. Although, the incidince of splenosis in

patients splenectomized for trauma is high, as long as they are asymptomatic, they do not require

surgical treatment. Herein, we report a case of idiopathic thrombocytopenic purpura recurrence

due to splenosis 5 years after the initial laparoscopic splenectomy. Laparoscopic treatment of

splenosis was performed successfully.

Abstract: Vascular endothelial growth factor (VEGF) induces proliferation of endothelial cells,

stimulates angiogenesis, and increases vascular permeability. Increased VEGF expression has

been associated with poor clinical outcomes in many malignancies. Several recent reports have

documented overexpression of VEGF in papillary thyroid cancer. We studied the relationship

between increased expression of VEGF and an increased risk of recurrence. The aims of this study

were to determine whether immunohistochemical expression of VEGF is related to local and

distant recurrence of papillary thyroid cancer and to evaluate the relationship between

hypervascularization and VEGF expression in papillary thyroid carcinoma. VEGF expression was

examined immunohistochemically in 45 papillary carcinomas. Ten patients with normal thyroid

glands who underwent surgery between 1991 and 1992 were used as controls. All patients were

followed for 12 years. Fifteen of the patients had local and distant recurrences. VEGF

immunostaining was evaluated semiquantitatively by a pathologist. The difference between the

recurrent (n = 15) and nonrecurrent (n = 30) carcinomas was statistically significant (P = 0.001).

VEGF expression was also stronger in papillary thyroid carcinomas than in normal thyroid tissues

(P = 0.001). There was a statistically significant correlation among the tumor size, regional

recurrence, distant metastasis, and the VEGF expression. These data indicate that VEGF staining

is strongly associated with an increased frequency of recurrence in papillary thyroid cancer and

that the immunohistochemical profile of the expression may be used as a marker for predicting

which tumors have metastatic potential.

Abstract: Phyllode tumor (PT) is extremely rare tumor of the breast. Distant metastasis occurs in

10-20% of patients with malignant phyllode tumor. The most common sites of metastases are the

lungs and bones. Although theoretically any organ may have metastasis, an isolated duodenum

metastasis has not been documented as yet in the English-language literature. We report herein a

case with a isolated duodenal metastasis from PT of breast in a 31 year-old-woman who

underwent right mastectomy 4 years before because of the recurrent malignant PT She presented

to our hospital with massive upper gastrointestinal bleeding. Clinical evaluation revealed a huge

mass originated from duodenum. Urgent laparotomy and pancreaticoduodenectomy were carried

out in order to remove the bleeding duodenal mass. The pathologic examination of the resected

specimen showed a malignant spindle cell tumor consistent with metastatic malignant PT. Our

case of gastrointestinal bleeding due to an isolated duodenal metastasis as a result of

hematogenous spread from malignant phyllode tumor of breast is unique in the English literature

and pancreaticoduodenectomy is a curative treatment for patients with isolated duodenal

involvement. (C) 2006 The WJG Press. All rights reserved.
