Abstract
Transanal minimally invasive surgery (TAMIS) is a surgical technique which allows the local excision of rectal benign tumors and early stage cancers measuring up to 4 cm and lying within 6-8 cm from the anal verge. It is performed by means of a disposable transanal platform and conventional laparoscopic instruments, proving to be effective and easily available. Hence, TAMIS soon became a valid alternative to other transanal resective procedures, especially transanal endoscopic microsurgery, and rapidly spread. Moreover, soon after its introduction, TAMIS started to be performed also using robotic technologies, but no clear advantages were found to date. This review is intended to provide a general overview on TAMIS, with a special focus on its association with robotic systems and the perspectives of this approach.
Highlights
Benign tumors and early stage cancers of the rectum measuring less than 4 cm and lying within 6-8 cm from the anal verge represented for a long time an indication for conventional transanal excision (TAE)[1]
transanal total mesorectal excision (TaTME) is a hybrid surgical technique employed for low rectal cancer combining a laparoscopic dissection for colonic mobilization and a mesorectal excision performed using a transanal approach through a GelPOINT platform or a rigid proctoscope
Transanal minimally invasive surgery (TAMIS) represents a valid therapeutic option in the surgical treatment of benign and malignant lesions of the rectum compared to transanal endoscopic microsurgery (TEM)
Summary
Benign tumors and early stage cancers of the rectum measuring less than 4 cm and lying within 6-8 cm from the anal verge represented for a long time an indication for conventional transanal excision (TAE)[1]. A systematic review with meta-analysis published by Clancy et al.[8] in 2015 reported significant differences in terms of negative resection margins, specimen fragmentation, and local recurrence in favor of TEM, whereas the postoperative complication rate was similar between conventional TEM and TAE.
