As endoscopic technology has developed and matured, the endoscopic resection of gastrointestinal tract polyps has become a widely used treatment. Colorectal polyps are the most common type of polyp, which are best managed by early resection before the polyp undergoes malignant transformation. Methods for treating colorectal tumors are numerous, including argon plasma coagulation, endoscopic mucosal resection, endoscopic submucosal dissection, and laparoscopic-endoscopic cooperative surgery. In this review, we will highlight several currently used clinical endoscopic resection methods and how they are selected based on the characteristics of the targeted tumor. Specifically, we will focus on laparoscopic-endoscopic cooperative surgery.

Keywords: Colorectal tumor, Endoscopic resection

Core tip: The best case scenario for patients with lower digestive tract tumors is to detect and resect the tumor before it undergoes malignant transformation. However, modern technologies for tumor resection are numerous and there may be specific indications for the implementation of one technology over another. Therefore, we will discuss the current clinical endoscopic resection methods and the process for selecting specific interventions. We wish to highlight laparoscopic-endoscopic cooperative surgery, because it may be of assistance in endoscopic treatment and could remarkably decrease the rate of later surgical repair.
