Comparative Study
Outcome of palliative operations for malignant bowel obstruction in patients with peritoneal carcinomatosis from nongynecological cancer.
Malignant bowel obstruction (MBO) secondary to peritoneal carcinomatosis carries a grave prognosis. We evaluated clinicopathologic factors that predict outcomes after palliative operations for MBO. ⋯ Only one third of patients with MBO from peritoneal carcinomatosis will have prolonged postoperative palliation with significant, but acceptable, treatment-related morbidity. TSF at discharge is a useful predictor of continued palliation for most patients. Patients with colorectal cancer may have superior survival outcome and better palliation; others are at risk for poor outcomes, especially in the presence of ascites and MBO of small bowel. In these patients, highly selective use of laparotomy is recommended.
