Multicenter Single-port Colectomy RCT

A Multicenter Prospective Randomized Clinical Trail on the Efficacy of the Single Port Laparoscopic Surgery Compared With Multiport Laparoscopic Surgery

This clinical trial is going to compare the single-port and multi-port laparoscopic colectomy for colon cancer treatment, in terms of safety, efficacy, and cost.

The investigators hypothesize that the single-port laparoscopic colectomy is not inferior to multiport laparoscopic colectomy.
