Brief insight regarding the use of transanal, laparoscopic, and robotic total mesorectal excision for rectal cancer.

In this article, we provide an important commentary on the original study Lu , which offers insight into the surgical efficacy of transanal total mesorectal excision (TaTME) laparoscopic total mesorectal excision (LapTME) in the management of low-lying locally advanced rectal cancer (LARC). We focus specifically on the rate of postoperative complications between the two using existing data from the literature. We additionally introduce robotic total mesorectal excision (RTME) and look at its postoperative complications relative to the TaTME and LapTME. LARC has been conventionally approached by open surgery. However, minimally invasive techniques have emerged over the past two decades as alternatives to open total mesorectal excision, namely robotic, laparoscopic, and transanal. Each approach has its supporters, but conflicting data on resection outcomes and complications has fueled ongoing debate over the optimal minimally invasive technique for low/mid-LARC. This article aims to extend on the data regarding the use of TaTME and RTME in the treatment of low/mid-LARC and further elaborate on their comparative efficacy relative to LapTME.
