Role of laparoscopic techniques in colorectal cancer surgery.

Laparoscopic intestinal resection is a relatively new application of endoscopic technology that has evolved as a direct result of the successes and benefits seen with laparoscopic gallbladder surgery. Currently acceptable and feasible laparoscopic intestinal resections include those for diagnostic procedures, fecal diversion, Crohn's disease, diverticulitis, familial polyposis, rectal prolapse, and palliative colorectal cancer surgery. However, the efficacy of laparoscopic resection for curative cancer surgery remains a topic of much debate. Issues surrounding curative laparoscopic oncologic resection include the ability to perform an acceptable oncologic resection, the question of morbidity and mortality compared to conventional surgery, and the problem of port site recurrences. Thus, at present, curative laparoscopic oncologic surgery must be conducted within the framework of a prospective, randomized clinical trial, which includes full informed patient consent.
