Meta-analysis of Early Postoperative Small Bowel Obstruction after Laparoscopic Colorectal Resection / 中国微创外科杂志

ABSTRACT

Objective To compare the efficacies of laparoscopic colorectal resection and conventional open surgery by collecting and investigating related studies with Meta-analysis.Methods Randomized controlled trials(RCT) on the outcomes of laparoscopic colorectal resection and conventional open surgery that published between January 1989 and March 2008 in English were collected and analyzed.The quality of the original investigations was evaluated,and the low-level reports were excluded.Then the odds ratio(OR) for the incidence of early postoperative small bowel obstruction between the two methods were calculated.ResultsTotally 12 studies including 3032 cases were analyzed.Among which,1522 patients received laparoscopy,33 of them developed early postoperative small bowel obstruction.1510 cases underwent open surgery,and 71 of these patients showed small bower obstruction before being discharged form hospital.The pooled OR was 0.46 with a 95% confidence interval of(0.30-0.69).Conclusion Compared with open surgery,laparoscopic colorectal resection is superior in the incidence of early postoperative small bowel obstruction.
