Pushing the Limits of Local Excision for Rectal Cancer: Transanal Minimally Invasive Surgery (TAMIS) for Rectal Cancer Using the Port-in-Port Technique

摘要

Background. Radical rectal resection remains the standard of care for the operative treatment of rectal cancer. Local excision via transanal minimally invasive surgery (TAMIS) using disposable transanal access ports is an increasingly more common alternative for selected patients. Because of significant variation in perineal anatomy, currently available disposable transanal ports do not allow adequate access for every patient. This report demonstrates TAMIS for one such patient via a novel approach using a single-incision laparoscopic port inserted within a disposable transanal access port.
