title: Rectosigmoid obstruction caused by ovarian cancer.
abstract: Out of a total of 379 patients with ovarian carcinoma a rectosigmoid stenosis was detected in 44 (12%). A barium enema was available in 27 cases, which revealed a severe stenosis (less than 1/2 lumen open) in 23, with an average length of 17 cm (5-40 cm). Five characteristic types of stenosis were found: solitary stenosis (n = 6), large spherical impression (n = 6), multiple stenoses (n = 4), long narrow tract (n = 6) and a total obstruction (n = 5). Desmoplastic reaction with tethering and/or parallel folds (n = 16) or fixation and/or angulation (n = 18) were frequently found, but tumour invasion was rare (n = 3). A sigmoid resection (n = 1) or colostomy (n = 3) was seldom needed, due to beneficial response to combined therapy.
