A Case of Dieulafoy's Lesion of the Terminal Ileum Treated by Colonoscopic Electrocoagulation / 대한소화기내시경학회지

ABSTRACT

Dieulafoy's lesion is an uncommon source of massive gastrointestinal hemorrhage and is understood to represent a tiny submucosal defect with fibrinoid necrosis at its base, overlying a large, tortuous, thick-walled artery in the muscularis mucosa. The lesion predominantly occurs in the proximal stomach, but may occur in all parts of the gastrointestinal tract including small bowel, colon and rectum. Moreover, Dieulafoy's lesion of the terminal ileum is very rare. We herein report a case of a patient who presented with massive hematochezia from Dieulafoy's lesion of the terminal ileum which was successfully controlled with endoscopic treatment by utilizing electrocoagulation.
