BACKGROUND Mesenteric vein thrombosis occurs rarely and is responsible for approximately 5-15% of all cases of acute mesenteric ischemia. The aim of this report was to discuss the management of mesenteric vein thrombosis based on our experience with 34 patients. METHODS In the present study, 34 patients who were admitted to our emergency surgery department between January 2007 and January 2010 with a diagnosis of acute mesenteric vein thrombosis were assessed retrospectively. Patients with peritoneal signs first underwent diagnostic laparoscopy to rule out perforation or bowel gangrene. We performed a second-look laparoscopy within 72 hours of the first operation. All patients were administered 100 mg/kg of the anticoagulant enoxaparin twice daily. In the 6th and 12th months of follow up, CT angiography was performed to evaluate recanalization of the veins. RESULTS CT angiography revealed superior mesenteric vein thrombosis in 25 (73%) patients, portal vein thrombosis in 24 (70%) patients, and splenic vein thrombosis in 12 (35%) patients. Eleven patients with peritoneal signs underwent diagnostic laparoscopy; eight of the patients underwent small bowel resection, anastomosis, and trocar insertion. During second-look laparoscopy, small bowel ischemia was found in two patients and re-resection was performed. CONCLUSION Early diagnosis with CT angiography, surgical and non-surgical blood flow restoration, proper anticoagulation, and supportive intensive care are the cornerstones of successful treatment of mesenteric vein thrombosis.

Orlistat is a pancreatic lipase inhibitor which is used to treat obesity. Due to the increasing prevalence of obesity, orlistat use is thought to rise progressively. We report an interesting case caused by orlistat use caught in the early stages of acute pancreatitis through imaging; in addition, the case had significantly elevated serum amylase levels. A 54-year-old male who had a history of orlistat treatment started 7 days before was admitted to the emergency department with complaints of abdominal pain, nausea and vomiting lasting for 24 h. Abdominal computed tomography revealed peripancreatic fat tissue edema and a heterogeneous appearance of the pancreas. Based on these findings, it was concluded that edematous pancreatitis was in its initial stage. Orlistat is a drug that is increasingly widespread use due to obesity. More attention must be paid when planning to prescribe orlistat to patients if there are risk factors for acute pancreatitis (alcohol use, height, serum calcium and lipid levels).

Objective: To evaluate the course and outcomes of pregnant patients with complicated gallstone disease and to reveal the experience of a tertiary center. Materials and Methods: The records of 92.567 patients were evaluated using searches for diagnoses with the terms of pregnant, pregnancy, gallstone, cholecystitis, cholangitis, choledocholithiasis, pancreatitis, and endoscopic retrograde cholangiopancreatography in pregnancy in the hospital database. Patients’ age, week of gestation, parity, body mass index, definitive diagnosis, attack episodes, treatment modalities, and obstetric and neonatal complications were evaluated. Results: Overall, 59 women were diagnosed as having complicated gallstone disease in pregnancy. Acute cholecystitis was the most commonly diagnosed complicated gallbladder disease (62.7%). Cholecystectomy was performed in 15 women during gestation. Perinatal outcomes were as follows: one (1.7%) maternal death, 4 (6.8%) preterm deliveries, 5 (8.5%) low-birth-weight fetuses, and 1 (1.7%) missed abortion were encountered. No fetal abnormalities were encountered. Conclusion: A significant proportion of women experience biliary disease during pregnancy. Herein, we presented our clinical experience because the diagnosis, course, and management of complicated gallstone disease in pregnancy is complicated.

OBJECTIVE The aim of this study was to compare contrast-enhanced computed tomography with diffusion-weighted magnetic resonance imaging in the evaluation of patients with acute biliary pancreatitis. MATERIAL AND METHODS Fifty-three patients diagnosed with acute biliary pancreatitis, between February 2012 and July 2015, were evaluated using diffusion-weighted magnetic resonance imaging and magnetic resonance cholangiopancreatography to explain the elevation of cholestasis enzymes and bilirubin levels at stanbul University. Contrast-enhanced computed tomography imaging was applied within 8 h following first evaluation. Demographic data, severity of pancreatitis, pancreatic apparent diffusion coefficient, and computed tomography severity index were compared. The significance of the results was evaluated using Statistical Package for the Social Sciences 21.0 program. RESULTS Median age was 53.39 (22-90) years in these 53 patients (26 were males and 27 were females). The mean Ranson criterion was 0.96 (0-4) and mean hospitalization duration was 16.02 (3-100) days. Twenty-eight patients were evaluated to have mild acute pancreatitis, whereas 16 were moderately severe and nine were severe based on the Revised Atlanta Classification. Mild pancreatitis score was 0.89, moderately severe pancreatitis score was 3.50, and severe pancreatitis score was 5.78 using the Balthazar score. Elevated C-reactive protein levels were not correlated with necrosis and the clinical severity score (p>0.05). There was no significant difference among the Balthazar score, magnetic resonance cholangiopancreatography-apparent diffusion coefficient score, and Revised Atlanta score in the evaluation of the severity of pancreatitis when the two techniques were compared. A statistically insignificant difference was found between the Balthazar score and magnetic resonance imaging results of clinically confirmed necrosis and non-necrosis patients. CONCLUSION It can be concluded that diffusion-weighted magnetic resonance imaging might be better than contrast-enhanced computed tomography in the diagnosis of acute pancreatitis as it avoids radiation exposure as well as the development of renal failure and pancreatitis aggravation due to the use of contrast for computed tomography. These results need to be confirmed with randomized prospective controlled studies.

OBJECTIVE Several damage-control procedures have been described in the literature in case of severe Calots triangle inflammation and fibrosis. In this report, we describe patients who underwent laparoscopic partial cholecystectomy using an endoscopic linear stapler. MATERIALS AND METHODS Five patients with acute cholecystitis underwent laparoscopic partial cholecystectomy in our clinic between January - December 2011. All patients had severe fibrosis and inflammation of Calots triangle. The anterior and posterior walls of the gallbladder were totally resected if possible. The gallbladder was transected at its neck or Hartmanns pouch, leaving a remnant gallbladder pouch behind. RESULTS Five patients had laparoscopic partial cholecystectomy with an endoscopic linear stapler. The main symptom of all patients on admission to the emergency room was abdominal pain. The mean time for the surgical procedure was 140 minutes (range, 120-180 minutes). Inflammation and fibrosis of Calots triangle was detected in all patients during surgery and a phlegmonous gallbladder was detected in one patient. Surgical drains were used in all patients and no biliary leakage was detected. Remnant common bile duct calculi were detected in one patient and this patient underwent endoscopic retrograde cholangiopancreatography one month after surgery. CONCLUSIONS When a reliable view of Calots triangle cannot be obtained due to severe inflammation and fibrosis during laparoscopy, laparoscopic partial cholecystectomy seems to be a safe and feasible alternative to open surgery with an acceptable morbidity rate.

Abstract Duplicated common bile duct, often associated with conditions like lithiasis, biliary cysts and pancreatobiliary maljunction, could result in highly morbid and potentially fatal biliary injuries. Precise preoperative diagnosis and classification still remain a challenge. A female patient undergoing emergency laparoscopic cholecystectomy for acute calculous cholecystitis sustained iatrogenic bile duct injury. A drainage tube was placed into the injured duct for post-operative conservative management. Post-operative tube cholangiogram revealed a double common bile duct with cystic duct opening distally. This was identified as a new variant not previously reported or classified. However rare, duplicated common bile duct could result in serious iatrogenic bile duct injury if unidentified during surgery. Knowledge of its existence is essential to avoid such injuries as preoperative diagnosis still remains a challenge. A thorough clinical and morphological study of previously reported variants is needed for a comprehensive classification to encompass newly discovered variants.

Aim: Single incision diagnostic laparoscopy (SIDL) may be an alternative procedure to multi-incision diagnostic laparoscopy (MDL) for penetrating thoracoabdominal stab wounds. The purpose of this study is sharing our experience and comparing two techniques for diaphragmatic status. Materials and Methods: Medical records of 102 patients with left thoracoabdominal penetrating stab injuries who admitted to Istanbul School of Medicine, Trauma and Emergency Surgery Clinic between February 2012 and April 2016 were examined. The patients were grouped according to operation technique. Patient records were retrospectively reviewed for data including, age, sex, length of hospital stay, diaphragm injury rate, surgical procedure, operation time and operation time with wound repair, post-operative complications and accompanying injuries. Results: The most common injury location was the left anterior thoracoabdomen. SIDL was performed on 26 patients. Nine (34.6%) of the 26 patients had a diaphragm injury. Seventy-six patients underwent MDL. Diaphragmatic injury was detected in 20 (26.3%) of 76 patients. The average operation time and post-operative complications were similar; there was no statistically significant difference between MDL and SIDL groups. Conclusion: SIDL can be used as a safe and feasible procedure in the repair of a diaphragm wounds. SIDL may be an alternative method in the diagnosis and treatment of these patients.

BACKGROUND The aim of this study was to investigate the efficacy of capsule endoscopy (CE) performed on patients who presented to emergency room with clinically evident gastrointestinal (GI) bleeding from unknown source and were hospitalized for follow-up. METHODS Total of 38 patients who underwent CE and were followed-up for evaluation of clinically perceptible GI bleeding with no obvious etiology in Istanbul Medical Faculty emergency surgery department were included in the study. Patient data, which were collected between January 1, 2007 and June 1, 2015, were reviewed retrospectively. RESULTS Of the 38 patients included in this study, 12 (32%) patients were women and 26 (68%) were men. Average age was 55.57 years (range: 20-88 years). Nine patients were using anticoagulants. Ten patients were followed-up in intensive care, and 7 patients underwent angiography. Angioembolization was performed for 1 patient who was diagnosed as having active bleed with CE. Average erythrocyte suspension replacement was 20.7 units. Total of 13 patients underwent surgery for bleeding found with CE. Eleven (34%) patients underwent double-balloon endoscopy, during which 5 patients were treated with cauterization and sclerotherapy was performed on 2. Four (18%) patients died during the study period: 2 died as result of bleeding from unknown source, 1 died of cholangiocarcinoma recurrence, and 1 died of anastomotic leakage. One patient was readmitted to hospital due to recurrence of bleeding. Nineteen (50%) patients were treated successfully based on CE findings. Diagnostic yield of CE was determined to be 78.9%. Average length of hospital stay was 32.68 days (range: 3-153 days). CONCLUSION CE is an effective tool to detect source of GI bleeding. CE should be first choice of evaluation method for patients admitted to emergency room with obscure overt GI bleeding once radiological imaging determines absence of obstruction.

Lymphangioma is a rare benign tumor that occurs due to abnormalities occurring during lymphatic development. It is usually seen in children and young adults. The incidence of lymphangiomas in the gastrointestinal tract is very low. Here we describe the case of 43-year-old woman with lymphangioma of the ileum with infiltrative polyposis-like appearing lesions diagnosed by capsule endoscopy and treated with segmental resection of affected intestinal part with laparotomy. Lesions involving mesentery and ileum were confirmed by pathology. After surgery, the patients symptoms improved. No further therapy was needed because of the benign manner of the lesions. Patient had no symptoms in 10 months follow-up after surgery.
