Comparative Study Of Transanal Glove Port And Traditional Laparoscopic Total Mesorectal Excision For Rectal Cancer On Short-term Outcomes

Objective: The aim of this study was to compare short-term results obtained with transanal glove port and traditional laparoscopic total mesorectal excision(TME)for rectal cancer.Methods: Between January 2015 and December 2016,a total of 23 consecutive patients with rectal cancer who subsequently underwent transanal glove port total mesorectal excision(transanal group)in our institution were retrospectively documented.This cohort was matched for gender and clinical T stage with a cohort of patients who underwent traditional laparoscopic TME(laparoscopy group)in the course of the same period.This analysis highlighted on short-term outcomes including surgical outcomes,pathological outcomes and complications.Results: No differences were observed between them with respect to baseline characteristics,thus emphasizing the comparability of both groups.In the distal rectal cancer,distal margin lengths was longer in transanal group than in the laparoscopy group[1.5(IQR1.0-2.0)cm vs 1.0(IQR0.8-1.0)cm,U=25.500,P=0.001].No significant differences were observed in operative time,blood loss,positive circumferential margin rate,quality of specimen,harvested lymph nodes,postoperative complication rate.Conclusions: This study demonstrated that glove port TaTME is safe and feasible.Compared with traditional laparoscopic TME,glove port TaTME achieves a longer distal margin without compromising other operative and quality parameters.Moreover,the glove port is a safe,readily available and inexpensive transanal access platform,can facilitate broad embrace of this approach.
