A Case of Rectal Cancer Associated with Pyometra which was Difficult to Diagnosis of the Preoperative Stage of Invasion

Abstract

A 76-year-old woman was admitted to our hospital because of anal bleeding, and emergency sigmoid co-lostomy was performed for severe vomiting on admission. Abdominal CT scanning revealed a rectal carci-noma invading the uterus and urinary bladder, and although on judged the difficult case to operate, because of the patient's poor condition, we operated on her request. Pyometra was found at operation, and there was no evidence of invasion of the uterus or urinary bladder by the rectal cancer. Low anterior resection and hys-terectomy were performed. This is an extremely rare case of a rectal cancer associated with pyometra.
