A 73-year-old man underwent laparoscopic low anterior resection for sigmoid colon cancer and multiple rectal adenomas that had been found after fecal blood was detected. The entire sigmoid colon to upper rectum was resected after mobilization to the splenic flexure, and end-to-end anastomosis was performed. The right pelvic cavity was closed, whereas the left side was not closed due to the placement of an indwelling drain. The patient developed small bowel obstruction 5 days after the initial operation. On the 15th postoperative day, surgical intervention revealed prolapse of the ileum into the left pelvic floor opening. The obstruction was relieved by partial resection of the ileum, and the peritoneal defect was sutured and closed. Whenever possible, closing the peritoneum on the bilateral pelvic floor should be performed in laparoscopic low anterior resection to prevent postoperative prolapse of intestine through a peritoneal defect.
