Rausa E, et al. Prosthetic Reinforcement in Hiatal Hernia Repair, Does Mesh Material Matter? A Systematic Review and Network Meta-Analysis. J Laparoendosc Adv Surg Tech A. 2021 Oct;31(10):1118-1123.

Results: Seventeen articles based on 1857 patients were enrolled in this article. The point estimation showed that when compared against the control group (NAM), the HH recurrence risk in AM and cruroplasty group was higher (relative ratio [RR] 2.3; CrI 0.8-6.3, RR 3.6; CrI 2.0-8.3, respectively). Postoperative complication rates were alike in all groups. The prevalence of mesh erosion after HHR is low.

Conclusions: This network meta-analysis showed that prosthetic reinforcement significantly reduced HH recurrence when compared with cruroplasty alone. However, there is not enough evidence to compare different mesh compositions.
