Current state of transanal minimally invasive surgery in the management of rectal cancer

Abstract

Rectal cancer surgery has undergone a rapid change over the last few decades. We have come a long way from abdominoperineal resection to minimally invasive sphincter preserving techniques. Colorectal cancer screening programs made it possible to diagnose patients at earlier stages and this has led to question the necessity of radical surgery and the possibility of organ preservation. The platform most recently added to the surgical armamentarium is transanal minimally invasive surgery (TAMIS). It utilizes conventional laparoscopic tools to perform endoluminal surgery in rectum. Along with the conceptual changes in rectal cancer management, TAMIS is more frequently used for local excision of malignant rectal tumors. This review highlights the recent advances and current state of the role of TAMIS in the management of rectal cancer at various stages.
