Colorectal cancer is one of the commonest forms of cancer worldwide. Laparoscopic surgery for colorectal cancer was first introduced a decade ago, although its long-term benefits (5-year survival rates for patients) have not been previously assessed. Ka Lau Leung from the Chinese University of Hong Kong and colleagues prospectively compared (over a 10-year period) the effects of laparoscopic and conventional surgery in a randomised trial of around 400 patients with colorectal cancer (in the upper rectum and sigmoid colon) treated at a hospital in Hong Kong.
5-year survival was similar for patients given either form of surgery (76% survival for laparoscopy, 73% for conventional surgery, with no statistical difference between the two values). The duration of laparoscopic surgery was significantly longer, whereas postoperative recovery time was substantially reduced compared with patients who received conventional surgery. However, laparoscopy was more costly than conventional surgery.
Dr Leung comments: "Laparoscopic resection of rectosigmoid carcinoma does not jeopardise survival and disease control of patients. The justification for adoption of laparoscopic technique would depend on the perceived value of its effectiveness in improving short-term post-operative outcomes".
