Robotic Versus Laparoscopy NOSE for Stage I-III Left-sided Colon Cancer

In this project, the investigator aims to provide the level 1 evidence for the comparison of robotic versus laparoscopic NOSE for the surgery of stage I-III colorectal cancer. the investigator hypothesize that, with the increased maneuverability of the current robotic system, robotic surgery will be a good option for patients with stage I-III colorectal cancer requiring a NOSE procedure.
