A Case of Gastrointestinal Stromal Tumor of the Proximal Jejunum Diagnosed by Double Balloon Enteroscopy / 대한소화기내시경학회지

ABSTRACT

A gastrointestinal stromal tumor (GIST) is a rare disease but is the most common nonepithelial neoplasm in the gastrointestinal tract. GIST accounts for 0.1~3.0% of gastrointestinal malignancies, and 20~30% of GISTs are found in the small intestine. GIST with extraluminal growth is difficult to diagnose. We report a case of a jejunal GIST with obscure bleeding that was diagnosed using double balloon enteroscopy.
