Intracorporeal laparoscopic resections for colorectal cancer: report of cases of abdominoperineal rectal excision and right hemicolectomy with 2 year follow-up.

Techniques for total intracorporeal laparoscopic abdominoperineal excision of rectum and right hemicolectomy for colorectal cancer are described in two patients with 2-year follow-up. Potential advantages over laparoscopically assisted procedures may be offset by increased operating time and expense for right hemicolectomy but the laparoscopic approach seems well suited to abdominoperineal rectal excision. The use of a secure retrieval system is advocated for specimen removal after right hemicolectomy.
