Abstract
The patient was a 71-year-old male. He had lower right abdominal pain at night. The pain became worse rapidly 12 hours after the on-set of the symptom. He had tenderness in the lower right abdomen. The rectal temperature was 39.1°C, which was relatively high compared with surface body temperature of 37.1°C. The abdominal CT revealed a colon tumor with enlargement of the distal ascending colon. According to the preoperative examination, intestinal obstruction by ascending colon cancer and colon perforation were suspected. On the same day the patient came in, an emergency operation was performed. As the operative findings, a tumor of the ascending colon, measuring 5cm in diameter, with extension to oral side of the colon was discovered. Two longitudinal colonic wall injuries measuring about 10cm were noted on the ascending colon. A large amount of seeds of watermelon and corns was suctioned from the intestinal tract. Right hemicolectomy, with ileostomy and colostomy was performed. No complications occurred in the postoperative course and he was discharged on the 23rd day after the operation.
