[Laparoscopic-assisted resection of colorectal tumours]

Two randomised controlled studies comparing laparoscopic-assisted and open surgery for colorectal cancer (the CLASICC and COLOR trials) have been published recently. There is now sufficient evidence that laparoscopic-assisted surgery is as effective as open surgery for cancer of the colon. There is no difference in short-term results (hospital mortality and complications) or 3-year survival rates. The substantial learning curve is a potential drawback for rapid implementation in daily practice and the procedure is associated with extra costs. The impact of the introduction of fast-track surgery has to be considered as another important way to reduce hospital stay. Wide application of laparoscopic-assisted resection of rectal cancer is not justified yet due to impaired short-term outcomes, such as increased circumferential resection margins and urogenital complications.
