Dieulafoy lesions, a rare cause of gastrointestinal hemorrhage, are caliber-persistent submucosal arteries without surrounding ulcers or mucosal lesions. Dieulafoy lesions rarely bleed profusely and may be missed during diagnostic endoscopy. Most of these lesions are located in the stomach; they have been reported only rarely in other parts of the gastrointestinal tract, including the small bow...

Purpose. To investigate the sensitivity of mesenteric angiography, technical success of hemostasis, clinical success rate, and complications of transcatheter embolization for the treatment of acute nonvariceal gastrointestinal hemorrhage. Material and Methods. A retrospective review of 200 consecutive patients who underwent mesenteric arteriography for acute nonvariceal gastrointestinal hemorrh...

hepatic artery aneurysms are a rare cause of upper gastrointestinal hemorrhage and may represent significant problems in both diagnosis and management. we report a 70 year old patient with gastrointestinal bleeding from a fistula between a 7 cm hepatic artery aneurysm and the duodenum. he underwent successful surgical management with endoaneurysmorrhaphy and duodenal wall repair.

AL-Amyloid rarely presents in the gastrointestinal tract as acute gastrointestinal hemorrhage, especially in the absence of clinical disease elsewhere in the body. There are no reported cases of monoclonal gammopathy of undetermined significance progressing to AL-Amyloid presenting as lower gastrointestinal hemorrhage. We report a case of a patient initially diagnosed with monoclonal gammopathy...

Massive upper gastrointestinal bleeding is a known complication of advanced sepsis in trauma patients and carries a grave prognosis. However, to our knowledge, an important cause of massive gastrointestinal bleeding, arterio-visceral fistula, has not been discussed in the literature. The most common cause of this unique clinical entity is penetrating high velocity abdominal injuries, altho...

Lower gastrointestinal hemorrhage remains a common disease, frequently presenting with acute life-threatening symptoms. Although prompt detection and treatment are imperative, it is difficult to diagnose lower gastrointestinal hemorrhage in an accurate and efficient manner. Most available modalities are time consuming. Computed tomographic angiography of the abdomen and pelvis, on the other han...

Small bowel diverticulum is a rare cause of gastrointestinal bleeding. The diagnosis and treatment of small bowel diverticular hemorrhage is clinically challenging before the development of deep enteroscopy. In this multicenter study from the Taiwan Association for the Study of Small Intestinal Diseases (TASSID), 608 patients underwent deep enteroscopy for obscure gastrointestinal bleeding duri...
