Controversies and consensus in transanal total mesorectal excision (taTME): Is it a valid choice for rectal cancer?

Abstract

Transanal total mesorectal excision (taTME) is a novel approach to radical surgery for low rectal cancer. taTME is associated with the benefits of a higher rate of free distal resection margins (DRM) under direct visualization, better visualization of the mesorectal plane, and the feasibility of overcoming the restriction of the distal pelvis. Thus, it is increasingly used globally. In this review, we investigated whether taTME yields better short- and long-term outcomes than laparoscopic TME.
