消化管出血を契機にカプセル内視鏡・バルーン小腸内視鏡で診断された小腸GISTの1例

Abstract

A 58 years old man was admitted with melena. Gastroscopy and colonoscopy couldn’t determine the source of bleeding. Capsule endoscopy demonstrates a submucosal tumor in jejunum. Single-balloon enteroscopy showed a submucosal tumor with active bleeding. Laparoscopy-assisted partial resection of small intestine was performed. Surgical resected specimens showed submucosal tumor with ulceration. Histopathologically, the tumor cells were spindle-shaped. Immunohistochemically, C-kit was positive so we finally diagnosed with small intestinal gastrointestinal stromal tumor (GIST) . This case suggest that patients with OGIB should be examined both by CE and BE.
