INTRODUCTION Cholecystectomy for benign gallbladder diseases can lead to previously undiagnosed gallbladder cancer during histopathological evaluation. Despite some controversy over its usefulness, histopathological evaluation of all gallbladder specimens is common in most hospitals. We evaluated the results of routine pathology of the gallbladder after cholecystectomy for benign gallbladder diseases with regard to unexpected primary gallbladder cancer (UPGC). METHODS Patients undergoing cholecystectomy because of benign gallbladder diseases between 2009 and 2013 were enrolled in this study. All gallbladder specimens were sent to the pathology department, and histopathological reports were examined in detail. The impact of demographic features on pathological diagnoses and prevalence of UPGC assessed. Data on additional interventions and postoperative survival for patients with UPGC were collected. RESULTS We enrolled 1,747 patients (mean age, 48.7±13.6 years). Chronic cholecystitis was the most common diagnosis (96.3%) and was associated significantly with being female (p=0.001). Four patients had UPGC (0.23%); one was stage T3 at the time of surgery, and the remaining three cases were stage T2. CONCLUSIONS Routine histopathological examination of the gallbladder is valuable for identification of cancer that requires further postoperative management.

Background/aim: Recently, surgery during admission has been advocated for acute cholecystitis, rather than delayed surgery after conservative treatment. This study was designed to perform early surgeries and analyze the criteria used for conservative management followed by delayed surgery. Materials and methods:After implementation of a study with the aim of performing early surgery, a retrospective review using a prospective database during the period of June 2009 to June 2011 was established. Early surgery during index hospitalization was offered to all patients, except those having criteria for conservative management.Results: There were 118 patients admitted for acute cholecystitis. Early and delayed surgeries were performed for 18 (15%) and 23 (20%) patients, respectively. Percutaneous cholecystostomy was performed for 10 (8%) patients with a success rate of 90% and significantly higher length of hospital stay (P = 0.001). Gallstone-related complications developed in 33 (28%) patients, causing significantly higher readmission rates (P = 0.001). Of the patients, 34 (29%) were neither operated on nor had complications. The subsequent cholecystectomy rate was calculated as 35%. The overall mortality rate was 1.7% for all groups. Conclusion:Although surgical treatment of acute cholecystitis, either by early or delayed surgery, has some specific morbidity and mortality, it should be kept in mind that conservative treatment modalities a have higher rate of recurrences and subsequent complications, which all cause additional morbidity and mortality in patients.

Objective: Cecal diverticulum is a rare entity, and can cause acute abdomen by the way of diverticulitis and perforation of diverticulitis. In this study, we aimed to perform an analysis of patients that have cecal diverticulitis, and presented with acute abdomen. Material and Methods: Patients who were admitted to emergency clinic between 2009-2012 and had acute abdomen due to cecal diverticulitis were included into study retrospectively. Results: Six patients were included in the study with a mean age of 34 years (range 24-43). Four patients were male and two were female (male/female: 2). All six patients presented with abdominal pain, additional symptoms were nausea in five patients, and vomiting in one patient. The mean white blood cell count was 11.900/mm 3 (5850-17.400/mm 3 ), while the remaining laboratory results were normal. There were no specific findings on abdominal X-ray or ultrasonography. The surgical exploration revealed an inflamed cecal diverticulitis and normal appendix in all patients. Five patients underwent appendectomy and diverticulectomy. Right hemicolectomy was performed in one patient due to suspicion of malignancy. The early postoperative period was uneventful in all patients. The mean length of hospital stay was 4.5 days with a range of 2-6 days. Histopathological examination showed acute perforated diverticulitis with underlying true diverticulum in three patients, and true diverticulum with acute diverticulitis in the remaining three patients. Conclusion: Pre-operative diagnosis of cecal diverticulitis is challenging due to symptoms and signs that resemble acute appendicitis. Diverticulectomy and incidental appendectomy is the treatment of choice in uncomplicated cases.

Hydatid disease is caused by Echinococcus granulosus. Hydatid cysts are commonly located in the liver and lungs. The occurrence of pancreatic hydatid cysts is very rare, even in endemic areas. Sinistral portal hypertension, which is rarely seen, occurs when a pathological process causes splenic vein occlusion. A 26-year-old male patient presented with abdominal pain. He had a history of operation for hydatid cyst of the lung 15 years ago. A left thoracotomy incision scar was observed during his physical examination. Laboratory findings revealed no abnormalities. Abdominal ultrasonography revealed a 96×69-mm lobular, contoured, well-circumscribed cystic lesion with thickened septation. Abdominal magnetic resonance imaging revealed a 100×76-mm smooth, bordered cystic lesion containing septations in the body and tail of the pancreas compressing the splenic artery and vein, causing sinistral portal hypertension. Dilatation was noted in the left gastroepiploic vein. The patient underwent cystotomy. Pancreatic fistula developed during the postoperative follow-up. The patient was discharged in 20 days without postoperative complications. No complications were observed during the follow-up period of 7 months. Surgery should be considered as a more conservative approach.

INTRODUCTION Postoperative pain after laparoscopic cholecystectomy has three components: parietal, visceral and referred pain felt at the shoulder. Visceral peritoneal injury on the liver (Glisson's capsule) during cauterisation sometimes occurs as an unavoidable complication of the operation. Its effect on postoperative pain has not been quantified. In this study, we aimed to evaluate the association between Glisson's capsule injury and postoperative pain following laparoscopic cholecystectomy. METHODS The study was a prospective case-control of planned standard laparoscopic cholecystectomy with standardized anaesthesia protocol in patients with benign gallbladder disease. Visual analogue scale (VAS) abdominal pain scores were noted at 2 and 24 hours after the operation. One surgical team performed the operations. Operative videos were recorded and examined later by another team to detect presence of Glisson's capsule cauterisation. Eighty-one patients were enrolled into the study. After examination of the operative videos, 46 patients with visceral peritoneal injury were included in the study group, and the remaining 35 formed the control group. RESULTS VAS pain score at postoperative 2 and 24 hours was significantly higher in the study group than control (P = 0.027 and 0.017, respectively). CONCLUSIONS Glisson's capsule cauterisation in laparoscopic cholecystectomy is associated with increased postoperative pain. Additional efforts are recommended to prevent unintentional cauterisation.
