Laparoscopic surgery for colorectal cancer was first introduced a decade ago, although its long-term benefits have not been previously assessed.
Dr Ka Lau Leung from the Chinese University of Hong Kong and colleagues compared the effects of laparoscopic and conventional surgery over a 10-year period.
The team performed a randomized trial that included around 400 patients with colorectal cancer.
The team found that 5-year survival was similar for patients given either form of surgery; 76% survival for laparoscopy and 73% for conventional surgery.
|5-year survival was similar in both groups.|
They found that the duration of laparoscopic surgery was significantly longer than conventional surgery, but postoperative recovery time was substantially reduced.
Overall, laparoscopy was more costly than conventional surgery.
Dr Leung comments, "Laparoscopic resection of rectosigmoid carcinoma does not jeopardize 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".
