小腸内視鏡によって確診しえた空腸癌の1例

Jejunal Carcinoma Diagnosed by Small Intestinal Fiberscope

　最近の小腸腫瘍に対する診断技術の進歩には目覚ましいものがある．著者らが小腸内視鏡を用いて内視鏡観察および直視下生検を行い術前に確定診断した空腸癌の1例を報告する．

　The patient was a 80 years old woman who presented symptoms of intestinal obstruction such as abdominal pain and vomiting. A follow-up fluoroscopic examination after upper G-I series study revealed bilateral filling defects showing an apple core sign in the proximal jejunum. Endoscopy revealed not only the lesion protruding into the lumen caused by narrowing, but also absent Kerckring's folds, reddish discoloration, irregular and uneven mucosa. Biopsy proved to be adenocarcinoma. On pathological study, the removed specimen, 4.5×1.5cm, showed ulceration as a configuration of Borrmann's type 2 carcinoma. Histological study showed papillotubular adenocarcinoma with subserous invasion.

　Small intestinal fiberscopic examination is a valuable method for diagnosing small intestinal tumor. We expect that it will have wider use in future.
