Transanal minimally invasive surgery

Trans-anal minimally invasive surgery (TAMIS) includes a group of techniques which allows access to the lower rectum and anus. Compared to traditional trans-anal excision, they provide better access, exposure and visualisation of the operative field while providing all the benefits of minimally invasive surgery like quicker recovery and morbidity. This broad group of surgical techniques include trans-anal endoscopic microsurgery (TEM), TAMIS, trans-anal total mesorectal excision (TaTME) and trans-anal submucosal endoscopic resection (TaSER) (1).
