Single incision laparoscopic right colectomy: a systematic review and meta-analysis.

Abstract

A meta-analysis was performed to compare the outcome of single incision laparoscopic right hemicolectomy with standard multiport laparoscopic right hemicolectomy. A systematic search of databases was carried out to extract comparative studies (randomized and non-randomized, prospective and retrospective). Data were analysed according to Cochrane Collaboration guidelines. A meta-analysis was performed when the data permitted this form of analysis. Nine comparative studies were retrieved comprising 241 patients with single incision and standard laparoscopy. None of these was randomized. There was no significant difference between the two methods for the primary end-points of mortality, morbidity and cancer-specific parameters and for the secondary end-points of operation time, blood loss, ileus, hospital stay and conversion. It was not possible to analyse pain and cosmetics data owing to insufficient information. Single incision laparoscopic right hemicolectomy is comparable with standard multiport laparoscopic right hemicolectomy in primary and secondary outcomes. Given current information it is justified to use single incision laparoscopic right hemicolectomy, but there is a need for a prospective randomized study.
