An Uncommon Cause of Small Bowel Bleeding from Appendiceal Carcinoma

Abstract

Massive hematochezia caused by a small bowel lesion is a rare entity. Currently, video capsule endoscopy and balloon-assisted enteroscopy are effective in identifying the source of small intestine bleeding. Herein, we report a case of small bowel bleeding caused by a nonmucinous appendiceal adenocarcinoma with ileal invasion which was detected by video capsule endoscopy and single-balloon endoscopy. Despite the advanced disease stage with hepatic and peritoneal metastases, as of September 2016 the patient has had 8 years’ disease-free survival after surgical resection and chemotherapy.
