Objective:To explore the value of ultracision and LigaSure in laparoscopic radical surgery for low rectal cancer. Methods:Sixty-one cases with low rectal cancer underwent laparoscopic resection using ultracision and LigaSure including 40 cases of rectal anterior resection and 21 cases of abdominal perineal resection (Miles operation). Results:Laparoscopic resection was performed successfully in all patients without conversion to open surgery. The mean operation time was 210 min， average bleeding volume was 200 ml and average number of lymph nodes removed was 15.3. There was no complication after operation and with no residual tumor cells at resection margins (top and bottom) was detected. Conclusions: Laparoscopic radical surgery for low rectal cancer using ultracision and LigaSure is not only as effective as the conventional open surgery， but also can significantly reduce bleeding and operation time.
