A Case of Acute Lower Gastrointestinal Bleeding from the Appendix / 대한소화기내시경학회지

ABSTRACT

In spite of the recent advances in diagnostic technology in clinical gastroenterology, identifying the cause of acute lower gastrointestinal bleeding is still a challenging task. Hematochezia from the appendiceal bleeding is rare and associated diseases are appendiceal endometriosis, angiodysplasia, arteriovenous malformation, Crohn's disease, appendicitis, carcinoid, lymphoma, diverticulosis, and intussusception of the appendix. We experienced a 31-year-old male with acute lower gastrointestinal bleeding from the appendix. Colonoscopy could demonstrate an active hemorrhage from the orifice of the appendix. Mesenteric arteriography revealed active bleeding from the appendix, which was managed with gelfoam embolization. Next day, appendectomy was done because of recurrent bleeding. Surgically removed appendix could not dislose any abnormal lesion except a small mucosal break.
