Summary

This study aims to elucidate whether there is a difference in long-term prognosis between laparoscopic surgery and open surgery in colon cancer patients with visceral obesity.

Conditions

  • Colonic Neoplasms

Interventions

PROCEDURE

Laparoscopic surgery

It refers to the scenario where the necessary anatomy for colon cancer resection is performed using laparoscopic instruments. In laparoscopic surgery, conversion to open surgery is defined as making an abdominal wall incision before completing the predetermined necessary anatomical dissection.This study does not permit the use of hand-assisted laparoscopic surgery, single-port laparoscopic surgery, or robotic surgery. The surgery will be performed according to standards of Complete Mesocolic Excision (CME).

PROCEDURE

Open surgery

It refers to a surgical procedure where the surgeon enters the abdominal cavity through an abdominal wall incision, gains adequate surgical space, and performs anatomical dissection under direct visual guidance, without relying on pneumoperitoneum or laparoscopic camera assistance.
