Clinical application 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 for rectal cancer.Methods: The clinical data of 39 cases with laparoscopic totalmesorectal excision were analyzed retrospectively.Results: 39 cases were successfully completed and none of the patients were converted to open surgery.The operation time was 140-280 min,the average of 150 min,and the intraoperative blood loss was 20-120 ml,the average of 40 ml.4-23 lymph nodes were resected,the average of 10.3 lymph.The postoperative convalescence of intestinal peristalsis was 30-72 hours,the average 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: Laparoscopic total mesorectal excision and anal sphincter preservation in the treatment for rectal cancer is a perspective minimally invasive technique,which is feasible,safe and effective.With the use of this technique,surgeons could accomplish higher rates of sphincter preservation,more accurate autonomic nerve preservation and good micturation with decreased postoperative pain and rapid recovery.
