BackgroundTransanal total mesorectal excision (TaTME) is a safe alternative to laparoscopic TME for mid and low rectal cancer. TaTME allows improved visualization of the surgical planes and margins, and may potentially improve oncological outcomes. However, functional results after total mesorectal excision (TME) are variable and there are currently only a few published studies that include functional data related to the outcomes of TaTME.MethodsFifty-four consecutive patients were included in this study: one group included 27 patients who underwent laparoscopic low anterior and the other included 27 patients who underwent TaTME. All patients were asked to complete five questionnaires related to quality of life (QOL) and function [EQ-5D-3L, EORTC-QLQ C30, EORTC-QLQ C29, Low Anterior Resection Syndrome score (LARS), and International Prostate Symptom Score IPSS]. All TaTME patients were operated on at The Gelderse Vallei Hospital by a single surgeon and had a follow-up of at least 6.6 months.ResultsThe EORTC-QLQ C30 and EQ-5D-3L questionnaires showed comparable outcomes in terms of QOL between the two groups. Almost all items evaluated by the EORTC-QLQ C29, including sexual outcomes, were similar between the two groups. One item concerning fecal incontinence, however, was scored worse for TaTME. There were no significant differences between the groups in terms of LARS symptoms or urinary function.ConclusionsPatients undergoing laparoscopic or transanal TME showed comparable functional and QOL outcomes. Although the TaTME technique is still evolving, this study indicates that this technique is a safe alternative to laparoscopic surgery in terms of functional outcomes for mid and low rectal cancers.
