Laparoscopic total mesorectal excision.

摘要

Several large randomised trials comparing laparoscopic versus open resection for colon cancer have shown that the laparoscopic method can provide an equivalent oncological outcome, a similar rate of complications, and a more rapid short-term recovery. However, as with open surgery, the safety and benefits of laparoscopy still lies with the surgeon, who must develop competency along a personal learning curve that assures proper patient selection, technical performance, and a low conversion rate. Because of the greater technical demands of rectal resection, many surgeons have doubted the wisdom of attempting laparoscopic total mesorectal excision (TME) for rectal cancer.
