Background: The purpose of this study is to clarify of the safety and the feasibility of the short-term and long-term results of the laparoscopic surgery for patients with rectal cancer from the accumulated data of 28 leading hospitals in Japan.
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. Total postoperative morbidity rate was 23.2% and 30-day mortality was not experienced. There were 83 stage 0 cancers, 495 stage I, 197 stage II, 230 stage III and 52 stage IV. Median operation time was 270 minutes (122-789 min.) and it took significantly longer time in Rb/P than Ra tumor (p
