Influence of transanal endoscopic total mesorectal excision on postoperative anal function in treatment of rectal cancer

Objective:To investigate the inl uence of laparoscopic-assisted transanal endoscopic total mesorectal excision(TME) on postoperative anal function in treatment of rectal cancer.Methods:Seventy-five patients with mid/low rectal cancer undergoing TME during May 2010 to January 2014 were selected.Of the patients,23 cases received laparoscopic-assisted transanal endoscopic approach(transanal endoscopic group),20 cases underwent open surgery(open surgery group) and 32 cases had laparoscopic procedure(laparoscopic group).The general surgical variables among the three groups were compared,and the function of the anus at er operation of the three groups of patients was evaluated by using Wexner's and XuZhongfa's scoring system,respectively.Results:Compared with either open surgery group or laparoscopic group,the intraoperative blood loss was reduced,and time to first postoperative l atus was shortened,but the operative time was prolonged in transanal endoscopic group(all P0.05).At one month at er operation,both score by Wexner's scoring system and good rate by Xu Zhongfa's scoring system in transanal endoscopic group were lower than those in open surgery group or laparoscopic group(all P0.05),but both of which showed no signii cant dif erence among the three groups at 3,6 and 12 months at er operation(all P0.05).Conclusion:Compared with open and laparoscopic TME,the recovery of anal function after laparoscopicassisted transanal endoscopic TME is poor for a short period of time,but has no obvious difference at a later period,and this procedure is more minimally invasive with fast postoperative recovery.
