A 74-year-old man was admitted our hospital with nausea and abdominal fullness. Abdominal X-ray and computed tomography both showed expanded small intestine and sigmoid colon. The patient was diagnosed as having ileus based on sigmoid colon cancer and underwent emergency colonoscopy to insert the transanal decompression tube. The efficacy of decompression tube was not sufficient and an emergency operation was performed. We found tumor of the rectum by digital examination and intraoperative colonoscopy revealed that the tumor was present in the rectum. A low anterior resection was performed and both tumors were resected. Minor leakage occurred at the anastomosis but the patient was discharged on the 70th day after the operation. It is important to confirm the anal side of a colorectal cancer stenosis as well as the oral side of the colon.
