“…The transanal platform is then introduced transanally and the rectum is insufflated with CO 2 to a pressure of 9-15 mmHg [43,52,95]. Different transanal platforms have been used by the included studies such as a transanal endoscopic operation (TEO) proctoscope (Karl Storz, Tuttlingen, Germany) [39,79,90,95], Endorec Trocar (Aspide Medical) [39,79,90,95,101], GelPOINT Path Transanal Access Platform (Applied Medical) [41,43,53,58,61,76,106,108], transanal access port (PAT, Developia Inc., Spain) closed on the back with GelPOINT (Applied Medical) [45,67], SILS Port (Covidien) [52,105] and single-channel colonoscope (Olympus, Tokyo, Japan) [42,111]. The included studies demonstrated that TaTME can be performed using dis-posable flexible or reusable rigid platforms.…”
