Unusual Causes of Upper Gastrointestinal Bleeding

Keyur Parikh et al. Gastrointest Endosc Clin N Am. 2015 Jul.

Abstract

Upper gastrointestinal (GI) bleeding is an important clinical condition managed routinely by endoscopists. Diagnostic and therapeutic options vary immensely based on the source of bleeding and it is important for the gastroenterologist to be cognizant of both common and uncommon etiologies. The focus of this article is to highlight and discuss unusual sources of upper GI bleeding, with a particular emphasis on both the clinical and endoscopic features to help diagnose and treat these atypical causes of bleeding.
