Methods: From May 1994 to February 2006, this study group comprised 1057 patients with rectal cancer located at middle, lower rectum who underwent laparoscopic surgery. Data including morbidity and mortality was obtained and 3-year survival rates were calculated by the Kaplan-Meier method according to the location of the tumor and the UICC staging.
Results: There were 665 males and 392 females. Laparoscopic procedures consisted of 888 anterior resection, 107 abdominoperineal resection, 50 inter-sphincteric resection and 10 Hartmann.
