Laparoscopic total mesorectal excision for rectal cancer surgery.

The introduction of total mesorectal excision in the early 1980s has improved local control and survival in patients with rectal cancer. Laparoscopic resections for colonic malignancies are gaining acceptance in the light of the recent evidence of oncologic adequacy from randomized clinical trials. Technical difficulties and the difference in the natural history of the disease have excluded rectal cancer from major clinical trials comparing laparoscopic to conventional rectal surgery. This review examined the feasibility, safety and oncologic outcomes of reported laparoscopic total mesorectal excision for surgical treatment of operable rectal cancer.
