症　例

　患　者：小○山○由○　18歳　女子学生

　家族歴・既往歴：特記すべきことなし

　現病歴：術前3カ月より食事と関係なく下腹部疝痛が時々出現し，また運動時にはいつも腹部不快感が認められた．悪心，嘔吐，裏急後重，排便時痛，発熱などはなく，尿路，性器の炎症症状も出現しなかった．月経は規則的で，いつもと変わらず，また排便回数は1日1行，硬便で，粘液，血液の混入は認めなかった．

　A 18 year-old-girl was admitted to our clinic complaining of lower abdominal pain and bloody stool since three months before.

　The initial barium enema and the colonofiberscopy showed marked stricture of the sigmoid colon. About two weeks later, the enlargement of its stricture was shown on the radiological and endoscopical findings. Histological examination of the biopsy specimen revealed moderate colitis. Laparotomy proved the so-called pelvic peritonitis, that is, the inflammatory cyst at Douglas's space and severe inflamation of the serosa and the mesentery at the sigmoid colon.

　Benign stricture of recto-sigmoid region is caused by two main diseases; the lesions of the large intestine itself and the lesions of the organs neighboring on it. The follow-up study by barium enema and colonofiberscopy is useful to the differential diagnosis of stricture of the sigmoid colon.
