[Future of laparoscopy in colorectal cancer surgery]

Laparoscopic surgery has been associated with less postoperative pain, an early return of bowel function, a shorter period of hospitalization and disability, and better cosmetic results. In the past decade laparoscopic techniques are increasingly being applied to colorectal surgical procedures. Diagnostic laparoscopy, the creation of stomas, and limited resections are becoming reasonable indications for benign diseases. However, the application of laparoscopic techniques to the curative resection of colorectal cancer is still controversial, owing to reports of cancer recurrence at the port site wounds. Port-site recurrence remains a leading concern regarding the widespread acceptance of laparoscopic resection for colorectal carcinoma. The last reports has presented that with careful technique, training and experience wound recurrences are rarely seen, suggesting that this phenomenon is primarily technique and advanced cancer stages related. The final results of the large randomized prospective studies may well determine the role of laparoscopy for colorectal cancer in the near future.
