Colorectal cancer: the role of laparoscopy

Since the first report in 1991 the laparoscopic resection of colon cancer is progressing slowly and just in the last 2-3 years is becoming more popular. The resistance to its use by some general and colo-rectal surgeons is receding. The explanations are that technology is evolving quickly and there is a worldwide diffusion of more sophisticated surgical instruments. Moreover several randomized trials have been published showing that the outcomes of laparoscopic colon surgery are similar or better than those of conventional surgery and the early reports suggesting the tumour dissemination were not confirmed. The revolution in oncological surgery that we are observing in these last decades with the introduction and diffusion of mini-invasive approach is comparable to that regarding conventional surgery during the period of Halsted. Therefore the principles of surgery accepted during the years must not be forgotten.
