The role of endoluminal surgery in a colorectal surgical practice. A global view

Abstract

Patients with large colorectal polyps or mucosal neoplasms not amenable to standard polypectomy have traditionally undergone colon resection. However, minimally invasive surgical techniques have gained popularity over the past two decades. Transanal approaches such as transanal endoscopic microsurgery and transanal minimally invasive surgery have enabled surgeons to treat mucosal neoplasms located in the rectum. Later on, robotic surgery was incorporated into the transanal approach. Meanwhile, there was no such treatment option for more proximal colonic neoplasms then, and endoscopic mucosal resection and endoscopic submucosal dissection emerged in Japan to provide resection in treating such proximal lesions. Nowadays, all procedures performed in a hollow organ integrating standard surgical (dissection, resection, suturing, homeostasis) and oncological principles (en-bloc resection, clean surgical margins) are merged under endoluminal surgery. Within the scope of this review, we aimed to elaborate an overview of the role of endoluminal surgery in daily colorectal surgery practice while focusing on endoscopic procedures.
