Objective To systematically evaluate the effects of biological mesh (BM) and non-absorbable synthetic mesh (SM) on the risks of recurrence, complications, and cost-effectiveness after ventral hernia repair. Methods The publicly published related researches of BM versus SM for ventral hernia repair were searched in the PubMed, Cochrane Library, Embase, Web of Science, CNKI, Wanfang, VIP, CBM databases from the establishment of the databases to August 1, 2021. According to the inclusion and exclusion criteria, the literatures were screened and the data were extracted, and the data that met the conditions were merged and analyzed. The meta-analysis was performed by RevMan5.4.1 software. Results A total of 26 studies with 3 259 patients were included, including 1 388 patients in the BM group and 1 871 in the SM group. The results of meta-analysis showed that the recurrence, surgical site infection, surgical site occurrence, reoperation rates, and medical costs in the BM group were higher than those in the SM group (P<0.05). There were no significant differences in the patch infection, seroma, hematoma, wound dehiscence, and readmission rates between the two groups (P>0.05). Conclusions SM during ventral hernia repair is better than BM on postoperative recurrence, surgical site infection, surgical site occurrence, reoperation, etc., and could reduce medical costs. In the future, it is tried to use more SM in patients with complicated ventral hernia such as cleaning pollution and contaminated environment.
