Technologies, technical steps, and early postoperative results of transanal TME

AbstractIntroduction: First described in 1982, TME overcomes most of the concerns regarding adequate local control after anterior rectal resection. TME requires close sharp dissection along the so-called Heald’s plane down to the levators, with distal dissection often cumbersome. In recent years, Transanal TME was introduced with the aim to improve distal rectal dissection and quality of mesorectal excision.Material and methods: A prospective, non-randomized study, started in 2013, is currently ongoing in two Italian Centers. Study objectives were assessing the safety of TaTME and TME quality. TaTME technique and technologies as performed in these centers and cumulative results at ≤30 postoperative days of the first 102 patients are reported.Results: Early postoperative morbidity and mortality rates were 33.3% (34 pts, 16 Clavien-Dindo I + II and 18 Clavien-Dindo III + IV + V), and 1.96% (two deaths), respectively. The quality of mesorectal excision according to Quirke was: complete in 97.1% and nearly co...
