Laparoscopic colorectal cancer surgery

BACKGROUND: A number of controversies exist in the laparoscopic treatment of colorectal cancer, and thus the technique has so far failed to gain widespread acceptance throughout the United Kingdom. This review aims to discuss these issues in the context of ongoing published trials, assessing both purported advantages and disadvantages. METHODS: The United States National Library of Medicine Medline database, and the Bath Information Data Service (BIDS) were searched using keywords related to laparoscopic colorectal cancer surgery. Recent surgical journals were also reviewed for relevant publications. Attempts have been made to quote only the most recent work from institutions with multiple publications using the same group of patients, in order to present the most coherent picture. The data are presented as randomized controlled trials, nonrandomized controlled studies, and series comprising more than 10 patients. CONCLUSIONS: This review confirms that laparoscopic colorectal cancer surgery is technically feasible, In addition patients lose less blood, have less immunosuppression, and have shorter postoperative ileus, in-patient stay, and require less analgesia. However, concerns still remain as to the development of port-site metastases, the longer operating times, and the overall cost of the equipment. In view of these concerns, the place of laparoscopically assisted colorectal cancer surgery is likely to remain controversial for some years yet. Randomized, controlled trials are as yet too few to provide definitive answers to all these issues. (C) 2000 by Excerpta Medica, Inc.
