Abstract
In recent years, minimally invasive surgery for colorectal cancer has seen remarkable improvement. For the laparoscopic surgery for colon cancer, earlier postoperative recovery and reduced hospital stays can be expected compared to those for open surgery. Also, no increase in perioperative morbidity and mortality has been shown. Furthermore, long-term oncological outcomes comparable to open surgery have been obtained. Although laparoscopic surgery for rectal cancer has shown good short-term postoperative outcomes, recent randomized controlled trials could not demonstrate non-inferiority to open surgery with respect to oncological safety. Further studies are required to confirm the impact of robotic surgery on colon and rectal cancer and the appropriate indications for transanal total mesorectal excision for rectal cancer.
