Laparoscopic Rectal Resection
Several large, prospective, randomized studies have demonstrated benefits from the use of laparoscopic surgery for colon cancer compared to open laparotomy. Laparoscopic colon cancer surgery is associated with a shorter and easier postoperative recovery. These advantages have also been shown for rectosigmoid cancers including upper rectal tumors (12–18 cm from the anal verge). However, there are very few prospective randomized trials evaluating the oncologic safety and benefits of laparoscopic resection for cancer in the lower two-thirds of the rectum.
