BACKGROUND: This series of patients with a history of roux-en-Y gastric bypass (RYGB) and cholecystectomy presented with symptoms consistent with obstructive biliary disease and massive biliary dilation of 15 mm or greater, suggesting a structural etiology. Findings from laparoscopic assisted transgastric endoscopic retrograde cholangiopancreatography (TGERCP) were a normal appearing ampulla without structural lesions or stones, suggesting a functional etiology, instead. STUDY DESIGN: Patients who underwent TGERCP from January 2008 to October 2016 and had a previous surgical history of RYGB and cholecystectomy were identified from an institutional database...

Chronic stress and depression are challenging conditions to treat, owing to their complexity and lack of clinically available and effective therapeutic agents. The aim of the present study was to investigate the mechanism by which berberine acts, by examining alterations to gastrointestinal tract histopathology and flora profile in a rat model, following the induction of stress. Research associating gastrointestinal flora and depression has increased, thus, the present study hypothesized that stress induces depression and changes in the gastrointestinal system...

Hepatic portal venous gas (HPVG) is a rare radiological sign that usually signifies an acute intra-abdominal process, most commonly bowel ischemia and sepsis. Few reports described an association with underlying gastric pathologies. We report a 60-year-old patient who presented with melena and chills and was discovered to have a gastric ulcer that appeared to have penetrated into a mesenteric varix. This, in turn, likely caused development of HPVG associated with fungemia. Treatment with a proton pump inhibitor and bowel rest was sufficient to resolve symptoms and the HPVG...

BACKGROUND: The objective of this study was to evaluate the coagulation profile by thromboelastography in morbidly obese patients who undergo bariatric surgery. Morbid obesity entails increased risk for thromboembolic events. There is no clear protocol for thromboembolic prophylaxis, regarding timing and length of treatment, in bariatric surgery. Thromboelastography provides data on a coagulation process from creation of the clot until the fibrinolysis. METHODS: Ninety-three morbidly obese patients were prospectively recruited within a 2-year period...

REVIEW
Gunter Keller, Diana Steinmann, Alexander Quaas, Viktor Grünwald, Stefan Janssen, Kais Hussein
Salivary gland carcinomas are rare tumours and therapy strategies are less standardized than in lung, gastric or breast cancer. Therapy is based on surgery, but not all carcinomas are completely resectable, e.g. because carcinomas often show infiltration of nerves. For further therapy decision pathology is recommended, but evaluation of potential targets for personalized therapy is not part of the routine panel. Many salivary gland carcinomas can be resistant to radio- and/or chemotherapy, which limits therapeutic options...

REVIEW
Ryan K Schmocker, Anne O Lidor
Benign gastric lesions represent various pathologic entities and management considerations. Upper endoscopy serves as the primary diagnostic modality for gastric lesions. Persistent or giant gastric ulcers represent unique subtypes of ulcers, requiring investigation of the underlying cause. Medical management remains the mainstay of treatment; however, indications for surgical intervention remain. Gastric polyps also represent diverse etiologies, and accurate diagnosis requires pertinent information and tissue samples...

R Šefr, L Němec, P Fabian, L Fiala
Mixed adenoneuroendocrine carcinoma (MANEC) is a rare tumour of the gastrointestinal tract composed of adenocarcinoma and neuroendocrine carcinoma. This pathologic diagnosis was recently defined by the WHO in 2010. The tumour may appear in various levels of the digestive tract including the oesophagus, stomach, colon and appendix. Biological behaviour of MANEC seems to be quite unpredictable and the prognosis uncertain. The disease may also mimic "simple" carcinoma. Only several tens of cases have been reported so far...

BACKGROUND: Superficial non-ampullary duodenal epithelial tumors (SNADETs) are relatively rare, but they are now being detected more frequently due to advances in endoscopic technology. Nevertheless, the pathological nature of SNADETs remains unclear and a management strategy for these tumors has not been established. METHODS: To elucidate the clinicopathological features, we conducted a retrospective analysis of 138 endoscopically resected SNADETs. Lesions were classified into two groups by histological grade according to the Vienna classification: category 3 (71 lesions, 51...

Zollinger-Ellison syndrome (ZES) is a rare clinical disorder, characterized by hypersecretion of gastric acid and multiple ulcers distal to the duodenal bulb. This occurs via the release of gastrin by neuroendocrine tumors known as gastrinomas. Patients with ZES present with nonspecific GI symptoms, which often leads to a delay in diagnosis. Our patient is a 55-year-old female with chronic abdominal pain, nausea, and diarrhea. She underwent EGD, EUS, MRCP, CT scans, and cholecystectomy, which did not reveal the cause of her symptoms...

OBJECTIVES: The term heterotopia, in pathology, refers to the presence of normal tissues at foreign sites. Gastric heterotopia has been reported anywhere in the gastrointestinal tract. However, the presence of gastric heterotopia in the rectum is very rare. METHODS: We, here, report a rare case of a localized 2-cm area of cratered mucosa with heaped-up borders in the rectum of a 51-year-old, asymptomatic woman who underwent screening colonoscopy. RESULTS: Histologic examination of the biopsy from the lesional tissue in rectum demonstrated fragments of rectal mucosa co-mingling with oxyntic- and antral-type gastric mucosa...
