A retrospective analysis of emergency double-balloon enteroscopy for small-bowel bleeding

Abstract

Although the role of emergency esophagogastroduodenoscopy (EGD) and colonoscopy for upper and lower gastrointestinal bleeding (GIB) is well defined, there are no data on the concept of emergency double-balloon enteroscopy (DBE) for small-bowel bleeding. The aim of this study was to retrospectively evaluate the concept of emergency DBE in overt obscure GIB and assess its impact on patient management. A total of 17 emergency DBEs for overt obscure GIB were carried out in ten patients (six women, four men; mean age 68 years, range 35 - 83). The following diagnoses were made: actively bleeding Dieulafoy lesions of the small bowel, n = 2; bleeding tumors, n = 4 (carcinoids n = 2, adenocarcinoma n = 1, lipoma n = 1); bleeding angiodysplasias and/or large arteriovenous malformation (AVM), n = 2; multiple ulcers, n = 1; and no diagnosis, n = 1. Endoscopic therapies included argon plasma coagulation (n = 6), injection of epinephrine (n = 3), and use of fibrin glue (n = 1). It appears that emergency DBE is technically feasible, facilitates both diagnosis and therapy and enables management of patients with massive overt obscure GIB. This study is a first step in establishing the concept of emergency DBE for patients with suspected small-bowel bleeding.
