The use of lightweight versus heavyweight mesh in open methods of inguinal hernia repair:A meta-analysis / 中国组织工程研究

ABSTRACT

BACKGROUND:It remains controversial in term of efficacy for the lightweight mesh and heavyweight mesh in inguinal hernia repair. OBJECTIVE:To compare the clinical therapeutic effects of lightweight mesh and heavyweight mesh in open methods of inguinal hernia repair with Meta-analysis. METHODS:Comprehensive electronic search strategies were developed using the fol owing electronic databasesPubMed, Cochrane Library, EMBASE, Medline, Ovid, CNKI, VIP, Wanfang and FMJS. The Literature published before February 2013 was searched. The randomized control ed trials about comparing lightweight mesh and heavyweight mesh in open methods of inguinal hernia repair were included. A data-extraction sheet was developed based on the preset standards. The data from eligible studies were pooled using RevMan5.1 software through Meta-analysis. RESULTS AND CONCLUSION:Eighteen trials with a total of 4 450 hernias met the inclusion criteria. The meta-analysis showed that there was a statistical difference between lightweight mesh group and the heavyweight mesh group on short-term pain [odd ratio (OR)=0.57, 95%confidence interval (CI) (0.43, 0.74), P0.5). According to limited evidence, there are some findings as fol owsthe lightweight mesh is of feasibility, safety and effectiveness for inguinal hernia repair. Because of the limits of sample and quality, more large-sample and high-quality trials are required to make a definite clinical evidence to use lightweight mesh for inguinal hernia repair.
