Small bowel tumors are rare among all gastrointestinal (GI) cancers. The most common histological subtype is adenocarcinoma. Adenocarcinoma of the small bowel is difficult to diagnose, often presents at a late stage, and has a poor prognosis. We describe a case of a patient with adenocarcinoma of the small intestine who presented to the hospital with nonspecific GI symptoms and obscure GI bleeding. An initial examination using abdominal computed tomography revealed negative findings. The patient underwent subsequent enteroscopy with capsule endoscopy and double‐balloon endoscopy, and an early‐stage jejunal adenocarcinoma was finally diagnosed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
