We report a case of intrapelvic gastrointestinal stromal tumor (GIST) of the small intestine with a 540° small intestinal volvulus. To our knowledge, this is the first reported case in the literature of intrapelvic GIST of the small intestine with volvulus.
A 79-year-old woman complaining of right lower abdominal pain was admitted to Hokkaido Prefecture Esashi Hospital. She was found to have an intrapelvic tumor about 10cm in diameter and a spiral intestine by abdominal enhanced computed tomography (CT). The intrapelvic tumor was first suspected to be a gynecologic tumor, and she was diagnosed as volvulus of the small intestine and the greater omentum. However, the intrapelvic tumor had been enhanced by superior mesenteric artery (SMA) angiography and was then diagnosed as an intestinal tumor.
At laparotomy, we found the 540° small intestinal volvulus. The intestine did not show necrotic changes and adhesions, and was easily moved to the normal position. The intrapelvic tumor measured was 14-10cm, and was located in the ileum 100cm from the end of Bauhin's valve. Partial resection of the small intestine involving the tumor was carried out. Postoperative pathological diagnosis was GIST of the small intestine. The immunohistochemical stainings of c-kit and CD34 were positive. Because she had no metastasis and had to undergo a radical operation, adjuvant chemotherapy such as STI571 was not performed. Fluorodeoxyglucose positron emission tomography (FDG-PET) revealed no recurrence and no metastasis 4 months after the operation.

当科で経験した胃と他臓器重複癌33例を同時性、異時性に分け検討した。重複癌の発生頻度は3.8%で二次癌発症までの平均期間は6年であった。同時性17例、異時性16例で男女比、平均年齢はそれぞれ15：2、71.9歳、13：3、68.6歳でいずれも男性に多い結果であり、また高齢化の傾向であった。胃癌の組織型では異時性で未分化型が50%を占め同時性17.7%との間に有意差を認めた。重複臓器は大腸が22病変(66.7%)と最も多く、また消化器系臓器が28病変(84.8%)を占めた。他臓器癌の病期分類では異時性で病期がすすんでおりIII期?IV期が50%を占め、同時性17.7%との間に有意差を認めた。胃癌を起点とした5年生存率は同時性62.7%、異時性42.2%で有意差はないものの異時性で予後不良の傾向であった。
