Brief Summary:
After introducing minimally invasive surgery, robotic surgery has been increasingly used in colorectal cancer. However, there is a few prospective study for robotic surgery. The aim of this trial is to evaluate the effectiveness and safety of robotic surgery in mid or low rectal cancer.

Condition or disease Intervention/treatment Phase
Rectal Neoplasm Procedure: Robotic surgery Procedure: Laparoscopic surgery Phase 2

Detailed Description:
This study was designed as randomized phase II trial (laparoscopic versus robotic). The primary end point is quality of mesorectal excision.
