Case Report: Jejunal angiodysplasia causing recurrent gastrointestinal bleeding presenting as severe anaemia and melena

摘要

Angiodysplasia of the gastrointestinal (GI) tract consists of ectasia of the submucosal vessels of the bowel. The evaluation of such patients needs proctoscopy, colonoscopy, small bowel enema, enteroscopy, capsule enteroscopy and angiography. Capsule enteroscopy has come up as an alternative to GI enteroscopy and colonoscopy in patients with occult GI bleeding; up to 52% cases of small bowel angiodysplasia in patients with occult GI bleed with negative upper GI and colonoscopy have been reported. The use of capsule enteroscopy potentially limits the hazard of radiation exposure from angiography and is less invasive than double balloon endoscopy. The treatment options for angiodysplasias include intra-arterial vasopressin injection, selective gel foam embolisation, endoscopic electrocoagulation and injection of sclerosants, with each of these being technically demanding, and requiring centres with good access to enteroscopy technology and trained gastroenterologists. Operative intervention has been indicated for refractory bleeding or lesions in sites not accessible to endoscopic interventions.
