Investigation of operative technique of laparoscopic total mesorectal excision and anal sphincter preservation in the treatment for rectal cancer

Objective To explore the feasibility,safety,operating essentials and therapeutic effect of laparoscopic total mesorectal excision with anal sphincter preservation in the treatment of rectal cancer.Methods The clinical data of 51 cases with laparoscopic totalmesorectal excision were analyzed retrospectively.Results 51 cases were successfully completed and none of the patients were converted to open surgery.The operation time was 128 -280 min(mean of 143 min),and the intraoperative blood loss was 20 - 130 ml(mean of 40 ml).9 -24 lymph nodes were resected(mean of 13.1).The postoperative convalescence of intestinal peristalsis was 30 -72 hours(mean of 48 hours).The postoperative hospital stay was 5-16 days,with an average of 9 days.All the secondary damages were managed successfully with laparoscopy.No complications of anastomotic leakage occurred after the operation.Conclusion Being familiar with the laparoscopic anatomy of the sigmoid colon and rectum,reasonable operational skills and standard manipulation are keys in preventing the secondary damage of Laparoscopic total mesorectal excision and anal sphincter preservation in the treatment for rectal cancer,It has the advantage of safety,less trauma and hemorrhage,slight pain,rapid recovery,It is relatively safe and is a simple procedure and more ideal method for the treatment of rectal cancer.
