65 laparoscopic peritoneoanal resections were performed. 80 patients, who underwent the traditional open surgery, comprised the control group. The mean operative time for the laparoscopic procedure was 202+/-47.7 min. Conversion was performed in 2 cases. A delayed transversostomy was performed in 10 cases because of the coloanal anastomosis ischemia. Lethality rate was 3%. 5-year survival was 76.9% after the radical laparoscopic procedure.
