For more than a decade, laparoscopic surgery has been adopted as a treatment of colorectal cancer. With promising evidences from multi-center prospective randomized studies, laparoscopic approach is accepted as an alternative for the management of colon cancer. However, laparoscopic surgery is still technically demanding and has little evidence to convince most surgeons of its usefulness for rectal cancer. Laparoscopic surgery for malignant diseases must stress on oncologic safety as well as its functional excellence. Oncologic principles in surgery for rectal cancer are complete resection of the tumor with safe margins, en-bloc resection of regional lymph nodes and appropriate treatment for metastatic lesion. Despite the lack of results in prospective randomized comparative trials, many studies have been investigating whether laparoscopic resection for rectal cancer can follow these principles. In this review, we analyze early outcomes, long-term result of oncologic adequacy in laparoscopic surgery for rectal cancer, and discuss its potential advantages.
