Risk factors for surgical site infection after groin hernia repair: does the mesh or technique matter?

Summary:Introduction Surgical site infections (SSIs) following groin hernia repair (GHR) are getting rarer in high income countries despite a wider use of meshes. Among the risk factors for SSIs, those related to the mesh and the surgical technique have rarely been described. Methods A registry-based multicenter study using prospectively collected data, including SSIs and their potential risk factors, was conducted in the French Hernia-Club. Results Between 2012 and 2019, 21,976 consecutive unselected adult patients aged 64.8  ±  15.4 years old (88.9% male) underwent GHR (83.5% unilateral). Fifty four percent were laparoscopic; 97.6% used mesh. The overall incidence of SSI was 0.26%. The incidence of SSI was respectively, 0.24% and 0.19% ( p   =  0.420) in open vs laparoscopic repairs; 0.19% and 0.25% ( p   =  0.638) for polyester vs polypropylene mesh; In adjusted multivariate analysis focusing on macroporous meshes (which were the most implanted meshes: 23,148 out of 24,099), there were no differences in terms of SSIs’ rates regarding the technique: open versus laparoscopy ( p  =  0.762) nor the type of mesh used: polypropylene versus polyester ( p   =  0.557). Conclusion The rate of SSI following GHR was low in this large registry study. Mesh type and surgical technique did not affect SSIs rates. Caution is advised when interpreting these data due to this very low rate of SSI and the potential for a type II error.
