Comparison of endoscopic versus open component separation technique for abdominal hernia:a Meta-analysis / 中华普通外科杂志

ABSTRACT

Objective To evaluate the efficacy and safety of endoscopic versus open component separation technique (CST) for abdominal hernia.Methods Systematic review was carried out to identify the controlled clinical studies comparing endoscopic CST with open CST for abdominal hernia.The Meta-analysis was performed with RevMan 5.2 software.Results The selection criteria was met in five studies.A total of 185 patients with abdominal hernia were included.Analysis of the data suggested that there was no significant differences in recurrence rate between endoscopic CST and open CST(P =0.84,risk difference =-0.01,95％ CI-0.12 to 0.10).However,endoscopic CST compared with open CST was associated with a significant reduction of postoperative wound complications (P ＜ 0.000 1,odds ratio =0.19,95％ CI 0.09 to 0.41).And there was no significant differences in operation time,intraoperative blood loss and postoperative hospital stay (all P ＞ 0.05).Conclusions As compared to open CST,endoscopic CST show equivalent clinical effects with similar recurrence rate.However,endoscopic CST was associated with a significant reduction of postoperative wound complications,and there was no significant differences in in operation time,intraoperative blood loss and postoperative hospital stay.
