초록
위장관 간질종양은 드물지만 소화관에서 가장 흔한 비상피 종양으로 소장에서 드물게 발생한다. 그동안 소장에 발생한 간질종양의 진단에 push 방식 소장내시경 검사, 소장조영술 등이 사용되었으나 진단율이 낮았다. 특히, 소장의 간질종양이 장막하 성장을 보이는 경우 진단이 더욱 어렵다. 저자들은 원인불명의 장 출혈 환자에서 이중풍선 소장내시경 검사로 진단한 근위부 공장의 장막하 위장관 간질종양 1예를 경험하여 보고한다.
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. (Korean J Gastrointest Endosc 2006;33:163-167)
