Colonic diverticular bleeding is the most common cause of lower gastrointestinal bleeding1,2 . Appendiceal diverticulosis is an uncommon clinical entity, with an incidence of 0.004%-2% in surgical pathologic specimens3,4 . Appendiceal diverticulitis in symptomatic patients should be treated with early resection, because of the risk of perforation and peritonitis; the rate of perforation is higher in appendicitis (27%) with diverticulosis than in appendicitis alone (6.6%)5 . Untreated appendiceal diverticulitis can also lead to massive gastrointestinal hemorrhage and abscess formation, and has a potential role in the development of pseudomyxoma peritonei...

Hereditary Hemorrhagic Telangiectasia (HHT) is a rare disease, with an autosomal dominant inheritance and a worldwide incidence of about 1: 5000 individuals. In >80% of patients, HHT is caused by mutations in either ENG or ACVRL1, which code for ENDOGLIN and Activin A Receptor Type II-Like Kinase 1 (ALK1), belonging to the TGF-β/BMP signalling pathway. Typical HHT clinical features are mucocutaneous telangiectases, arteriovenous malformations, spontaneous and recurrent epistaxis, as well as gastrointestinal bleedings...

Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure of the diagnosis and treatment of biliary and pancreatic diseases. ERCP combines both endoscopic and radiologic imaging. Despite the fact that it is widely considered as relatively safe and useful procedure when performed by an experienced endoscopist, ERCP may potentially result in complications due to its invasive nature. These complications vary in severity and include post-ERCP pancreatitis, cholangitis, hemorrhage and perforations of the gastrointestinal tract...

Gastric mucosal cells, particularly parietal and chief cells, are usually affected by exogenous, and endogenous stimuli-induced gastritis. The integrity of these cells and their alterations are involved in the pathogenesis of numerous gastric disorders. Omeprazole, a gastric acid secretion blocker, is commonly used for gastrointestinal diseases due to its antioxidative stress and anti-inflammatory properties. Little is known regarding how omeprazole modulates the re-epithelialized effect on gastric mucosal cells associated with gastrointestinal disorders...

A 50-year-old man with lung adenocarcinoma (c-T1aN2M1b) experienced reddish purpura mainly on the lower legs after receiving 12 cycles of second-line chemotherapy with docetaxel. There was tumor enlargement on computed tomography performed to assess the therapeutic response, so paraneoplastic IgA vasculitis was considered. IgA vasculitis was diagnosed based on a biopsy of the skin lesion and histology of an upper gastrointestinal hemorrhagic mucosal erosion. As IgA vasculitis can lead to serious gastrointestinal or systemic complications, IgA vasculitis should be considered as a differential diagnosis for rashes in patients with malignancy...

An 84-years old woman, medicated with acenocumarol, was admitted to the Emergency Room with lower abdominal pain and nauseas and no history of trauma. She was medicated with acenocumarol and had a non-measurable international normalized ratio. The findings of the bowel ultrasound, ileocolonoscopy and biopsies specimens were suggestive of intramural bleeding of the ileum, ileocecal valve and cecum. Spontaneous intramural bleeding of the gastrointestinal wall associated with oral anticoagulation is rare.

Hemosuccus pancreaticus is an unusual gastrointestinal hemorrhage through the main pancreatic duct. We report a rare case of hemosuccus pancreaticus due to a simple mucinous cyst of the pancreas. A 52-year-old man who had been followed-up for a suspected branch duct intraductal papillary mucinous neoplasm (IPMN) visited the emergency room due to hematochezia. Endoscopy showed active bleeding from the ampulla. Computed tomography revealed hemorrhage in a 2.0-cm cystic mass in the pancreatic body. The patient was diagnosed with hemosuccus pancreaticus caused by bleeding into the main pancreatic duct from suspected IPMN...

The bovine gastrointestinal microbiota is a complex polymicrobial ecosystem that plays an important role in maintaining mucosal health. The role of mucosal microbial populations in the pathogenesis of gastrointestinal diseases has been well established in other species. However, limited information is available about changes in the fecal microbiota that occur under disease conditions, such as hemorrhagic diarrhea in feedlot cattle. The objectives of this study were to characterize the differences in fecal microbiota composition, diversity and functional gene profile between feedlot calves with, and without, hemorrhagic diarrhea...

Inflammatory fibroid polyps (IFP) are an extremely rare entity that arise within the submucosa of the gastrointestinal tract, and represent less than 0.1% of all gastric polyps. They are most commonly localized to the gastric antrum, small intestines and recto-sigmoid colon. IFPs are most commonly found incidentally upon endoscopic evaluation in the absence of symptoms. Presenting symptoms depend on the location of the tumor, although polyps located in the stomach most commonly present with epigastric pain and early satiety...
