Abstract
Abstract
Background
Gastrointestinal vascular malformations are rare benign vascular neoplasms of the gastrointestinal tract, with the rectosigmoid region being the most frequently involved site. Patients often manifest with recurrent, intermittent rectal bleeding, which might occasionally be life-threatening.
Case presentation
A 39-year-old man with a history of hemorrhoid operations twice was presented to our gastroenterology department with blood in the stool and abdominal pain. After the colonoscopy, multiparametric MRI, and CT examinations, robotic low anterior resection was performed with the diagnosis of rectosigmoid venous malformation. The histopathological examination confirmed the diagnosis.
Conclusion
Colonoscopy is the preferred method in diagnosing rectosigmoid vascular malformation, but wrong and delayed diagnoses are common. Thus, imaging modalities might add to colonoscopy in equivocal cases.

Abstract
BACKGROUND/AIMS The aim of the present study was to investigate whether pancreas cyst fluids should be divided into two for cytological diagnosis and biochemical tests. MATERIALS AND METHODS The present study was conducted with fluids aspirated from 12 pancreas cysts. The fluids were divided into two and sent to the cytopathology (fluid 1) and biochemistry (fluid 2) laboratories. Fluid 1 was centrifuged at the cytopathology laboratory. Cytology slides were prepared from the deposit, and the supernatant was sent to the biochemistry laboratory. Fluid 2 was centrifuged at the biochemistry laboratory, and amylase, carcinoembryonic antigen, and cancer antigen 19.9 levels were determined in the supernatant. These procedures were repeated for fluid 1 from the cytopathology laboratory. The remaining fluid 2 was sent to the cytopathology laboratory. Fluid 1-like slides were prepared from fluid 2 in the cytopathology laboratory. Cytological diagnoses of fluid 1 and fluid 2 were compared, and the Pearson correlation coefficient for biochemical test results was identified. RESULTS 92% of fluid 1 and 50% of fluid 2 were diagnostic. Biochemical test results of fluid 1 and fluid 2 were similar, and the Pearson correlation coefficient was high. CONCLUSION Our results showed that pancreatic cyst fluids did not need to be divided into two for cytological diagnosis and biochemical tests. Following centrifugation of the whole fluid at the cytopathology laboratory, the deposit and the supernatant can be used for cytological diagnosis and for biochemical tests, respectively. With this protocol, the sensitivity of cytological diagnoses and biochemical tests of pancreatic cyst fluids may increase.

Abstract
BACKGROUND/AIMS Endoscopic papillectomy (EP) has emerged as an alternative to surgery in the management of ampullary lesions. The aim of this study is to evaluate feasibility, efficacy, safety, outcome, and impact of EP in the management of benign ampullary lesions. MATERIALS AND METHODS This is a multicenter, retrospective study of 44 patients who had EP of benign ampullary lesions. RESULTS Over the 11-year period, 44 (55.7%) of 79 patients underwent EP for benign ampullary lesions. Complete resection was achieved in 40 patients (91%). An underlying adenocarcinoma was the only risk factor for incomplete resection. Twenty-eight lesions (63.6%) were resected en-bloc and 16 lesions (36.4%) were resected in piecemeal fashion. Post-papillectomy histopathologic diagnoses were tubular adenoma in 14 patients (32%), invasive adenocarcinoma in 9 patients (20.5%), tubullovillous adenoma in 7 patients (16%), tubullovillous adenoma with carcinoma limited to the mucosal layer in 5 patients (11.3%), adenoma with high-grade dysplasia in 4 patients (9%), neuroendocrine tumor in 1 patient (2.3%), ganglioneuroma in 1 patient (2.3%), hamartomatous polyp in 1 patient (2.3%), adenofibroma in 1 patients (2.3%), and Brunner gland hyperplasia in 1 patient (2.3%). Seven (15.9%) procedure-related complications occurred: 3 (6.8%) bleeding, 2 (4.5%) pancreatitis, 1 (2.3%) abdominal pain, and 1 (2.3%) stent migration to the pancreatic duct. Seven patients (17%) had recurrence. CONCLUSION Endoscopic papillectomy is a safe and effective method and can be considered as a first-line approach in patients with benign ampullary lesions with intent for cure. It also allows for correct histological diagnosis and staging.

Abstract
BACKGROUND/AIMS Retraction of the main papilla toward the biliary system was observed in 70% of patients with primary sclerosing cholangitis (PSC). However, this observation was confounded by the fact that all of the patients with this finding had a prior history of sphincterotomy. The aim of the present study was to observe whether main papillary retraction can be seen in patients with naïve papillae and accompanies the progression of the disease. MATERIALS AND METHODS The study was conducted in a single tertiary reference center and included 4 patients with PSC. RESULTS Main papillary retraction was seen to emerge with progression of PSC after an initial presentation with intra and extrahepatic involvement in 2 patients and after progression from intrahepatic to extrahepatic bile ducts in 1 patient. Main papillary retraction was seen in 2 patients with naïve papillae and could be detected by magnetic resonance cholangiography in 1 patient. CONCLUSION Retraction of the main papilla can be seen in patients with PSC regardless of prior sphincterotomy history.

Abstract
BACKGROUND/AIMS Endoscopic retrograde cholangiopancreatography has become the standard treatment for common bile duct stones worldwide. However, there are only a few reports with small number of patients concerning the factors that contribute to the technical difficulty of endoscopic retrograde cholangiopancreatography in these patients. In this study we aimed to investigate these factors in a large group of patients. MATERIALS AND METHODS All patients with a naıïve papilla (n=1850) who underwent endoscopic retrograde cholangiopancreatography during a study period of 2 years were prospectively evaluated. Of these, 757 patients with common bile duct stones were included in the study. Following successful cannulation, patients who needed either more than one episode for stone extraction or mechanical lithotripsy, extracorporeal shock wave lithotripsy, or patients in whom stone extraction could not be achieved endoscopically and underwent surgery were regarded as having "difficult stones". Age, sex, laboratory parameters, endoscopic and cholangiographic findings were recorded in all patients. Predictive factors for difficult stones were investigated using univariate and multivariate analysis. RESULTS The study group consisted of 432 women and 325 men with a mean age of 60±16 years (range, 4-96). Of the total 757 patients, 654 (86.4%) had easy and 103 (13.6%) had difficult stones. Endoscopic stone extraction was successful in 98.1% of patients. A stricture distal to the stone (OR: 8.248), smaller common bile duct/stone diameter ratio (OR: 0,348), stone diameter (OR: 1,187) stone impaction (OR: 1,117) and higher bilirubin levels (OR: 1,1) were found to be independent predictors of difficult stone extraction on multivariate analysis. CONCLUSION Endoscopic retrograde cholangiopancreatography is a very effective method for the treatment of common bile duct stones. Presence of a stricture distal to the stone, smaller common bile duct/stone diameter ratio, stone diameter, impacted stone, and higher bilirubin levels are significant predictors of difficult stone.
