French multicentre prospective observational study of laparoscopic versus open colectomy for sigmoid diverticular disease

BackgroundThe aim of this study was to compare in-hospital morbidity and mortality rates after elective laparoscopic and open colorectal surgery for sigmoid diverticular disease (SDD).MethodsThis prospective national multicentre observational study included all consecutive patients undergoing open or laparoscopic elective colectomy for SDD in a 4-month period between June and September 2002. Postoperative in-hospital mortality and morbidity in the two groups were compared.ResultsThree hundred and thirty-two consecutive patients undergoing either laparoscopic (163 patients) or open (169 patients) colectomy for SDD were analysed. Overall postoperative mortality and morbidity rates were 0·3 and 23·8 per cent respectively. The morbidity rate was significantly higher in the open than in the laparoscopic group (P < 0·001), leading to a significantly longer hospital stay (P < 0·001). The morbidity rate remained significantly higher in the open group when the patients were matched for age (P = 0·015) or American Society of Anesthesiologists score (P = 0·028). An open procedure (relative risk (RR) 2·13 (95 per cent confidence interval (c.i.) 1·29 to 3·45)), age over 70 years (RR 1·62 (95 per cent c.i. 1·14 to 2·30)) and intraperitoneal contamination (RR 2·54 (95 per cent c.i. 1·18 to 5·50)) were identified as independent risk factors for morbidity.ConclusionA laparoscopic approach to elective treatment of SDD may be associated with reduced postoperative morbidity and hospital stay. A randomized study is required to confirm these results.
