Abstract: 【Abstract】〓Objective〓To assess the value of anus preserving operation with sustaining anastomotic tube in laparoscope for lower rectal cancer. Methods〓The alimentary tract reconstruction by colo-rectal (anal) anastomoses with a sustaining anastomotic tube through anal in laparoscope after TME in 14 cases of lower rectal cancer. Results〓Forteen ultralow colo-rectal/anal anastomoses were successfully completed laparoscopically and the anastomosis time was 15-30 min. The mesorectum was cut completely. The distance from stoma to the dentate line was less than 2 cm in 8 patients and colo-anal anastomosis was performed in 6 patients. The function of anal sphincter and micturition recovered smoothly after the operation without anastomotic stoma leakage and anastomotic stoma stenosis. The defecation function was satisfactory in 85.71% (12/14) cases. Postoperative 5 year survival and recurrence were 78.57% (11/14), 7.14% (1/14) respectively by life table method. Conclusion〓The anus preserving operation with sustaining anastomotic tube is safe and practicable in laparoscope for lower rectal cancer.
