title: The role of minimally invasive surgery and outcomes in colorectal cancer.
abstract: For some time now, there has been significant interest in understanding and defining the role of minimally invasive surgery in colorectal cancer. Laparoscopic surgery has been shown to have similar or better outcomes compared with open surgery. Recently, prospective randomized trials have demonstrated oncologic outcomes of laparoscopic colon surgery equivalent to those for open surgery. However, the technical challenges of performing laparoscopic resection of rectal cancers and the uncertainty of the oncologic quality of the surgical resection have hindered the growth of minimally invasive rectal surgery. Robotic rectal surgery has recently emerged as an attractive alternative to laparoscopic surgery because it allows for superior visualization within a narrow pelvic field and more precise dissection. Studies of robotic rectal resection have suggested similar or potentially improved short-term oncologic outcomes when compared with laparoscopic rectal resection. Ongoing randomized studies will provide additional insight into the role of laparoscopic and minimally invasive robotic surgery for rectal cancer.
