Mechanical intestinal obstruction in patients with gynecologic disease: a review of 368 patients.

To review the management of intestinal obstruction associated with gynecologic disease, the authors studied the records of 368 patients with acute intestinal obstruction. Most patients (83%) had gynecologic malignancies. Obstruction of the small intestines was more common than obstruction of the large intestines (77% versus 23%). Major causes of mechanical small bowel obstruction included extrinsic neoplasms (62%, mostly ovarian carcinomas), radiation therapy-associated strictures and adhesions (17%), postoperative adhesions (14%), and inflammatory strictures and adhesions (3%). Obstruction of the colon was caused mainly by extrinsic neoplasms (45%), strictures and adhesions associated with radiation therapy (26%), fecal impaction (9%), and intrinsic neoplasms (8%). Gastrointestinal intubation successfully relieved 81% of small bowel obstructions caused by postoperative adhesions. Tube suction alone was rarely successful when the obstruction was caused by malignant neoplasms. The prognosis was dependent on the cause of the underlying disease. The cases studied in this report were compared with a large number of cases of bowel obstruction in general surgery. It is concluded that bowel obstruction associated with gynecologic disease has unique features deserving wider recognition.
