Laparoscopic Colorectal Surgery has evolved significantly since the 1990s. In the last few years, we have seen major advances in laparoscopic rectal cancer surgery. They are robotic-assisted rectal cancer surgery and transanal total mesorectal excision (taTME), i.e. laparoscopic surgery to free up the lower part of the rectum via the anus. taTME has been shown to provide a better margin around the cancer, thus reduce the chance of the cancer recurrence.
