Abstract

INTRODUCTIONObscure gastrointestinal bleeding (OGIB) refers to blood loss from unclear origins after esophagogastroduodenoscopy (EGD), colonoscopy or radiological evaluation of the small bowel. Patients may present with overt bleeding, hematemesis, hematochezia or melena, or complain of positive fecal occult blood. Small intestinal bleeding or middle gastrointestinal bleeding (MGIB) is defined as the source of bleeding that is located between the ligament of Treitz and the ileocecal valve. It has been reported that MGIB accounts for 80% of the OGIB. Because of the length and complexity of the small bowel, it is quite difficult to diagnose and manage patients with OGIB. It was not until the advent of capsule endoscopy (CE) and double‐balloon enteroscopy (DBE) that light was shed on the etiology of this disease.The etiology of OGIB contributes significantly to the diagnosis and management of the patients with OGIB as well as the prevention of the disease. The etiologies of lower gastrointestinal bleeding (LGIB) in Chinese patients were summarized in an earlier systematic analysis of the Chinese studies. The most common causes of LGIB were colorectal cancer, colorectal polyps and colitis. However, these findings were based on the colonoscopy database and small intestinal disease might have been missed. The etiologies
