A 76-year-old woman visited the emergency room complaining of anal discomfort. Yellowish mucosa was prolapsed from the anus, and it was easily reductable with a hand manipulation. She admitted the hospital to do further examination four months later because of repeated. Barium enema roentogenograms revealed a smooth and well defined tumor, about 4cm in size, in the sigmoid colon 35cm from the anus. Colonoscopic examination showed a smooth and yellowish submucosal tumor with a positive cushion sign. These findings were compatible with a lipoma of the sigmoid colon, and endoscopic mucosal resection of the tumor should not be indicated. Under general anesthesia with muscle relaxation, we successfully drew the tumor to the outside the anus by using a colonoscope, and resected directly without laparotomy or laparoscopy. The patient resumed diet from the next day after surgery. This method may be applicable to a benign lower colonic tumor under general anesthesia with muscle relaxation.
