Laparoscopic colectomy for cancer: a review

Abstract

<h4>Background</h4>The success of laparoscopic cholecystectomy in providing patient benefits in the immediate postoperative period has led to laparoscopic techniques being used for many other intra-abdominal procedures. Colorectal resection for malignancy is one of the more contentious applications of this new technology, because the postoperative benefits are more subtle and the long-term onco logical results are as yet unknown.<h4>Methods</h4>A review of the English-language literature was undertaken in order to collate and analyse all published series where 20 or more laparoscopic colectomies were performed. and where the indication for resection in the majority of cases was adenocarcinoma of the colon.<h4>Results</h4>Laparoscopic colectomy for cancer can be performed safely by experienced surgeons, although there is a considerable learning curve for the procedure. The expected benefits of minimal access surgery are provided by laparoscopic colectomy, although to a lesser extent than that seen with other procedures. The oncological safety of the procedure is as yet unproven. It is clear that an equivalent resection can be performed, but not whether this translates to an equivalent recurrence and survival rate. Reports of isolated port site recurrences are of concern.<h4>Conclusions</h4>Early results of laparoscopic colectomy for cancer are encouraging, although the fate of this procedure rests with the analysis of the large multicentre prospective randomized trials currently under way, particularly with regard to the long-term recurrence and survival rates.
