Background: Hiatus hernia (HH) contributes to the pathophysiology of gastroesophageal reflux disease (GERD). Mesh-augmentation of surgical repair might be associated with a reduced risk of recurrence and GERD. However, recurrence rates, mesh-associated complications and quality of life (QOL) after mesh versus suture repair are debated. The aim of this meta-analysis was to determine HH recurrence following mesh-augmentation versus suture repair. Secondary aims were to compare complications, mortality, QOL and GERD symptoms following different repair techniques. Methods: A systematic literature search of the PubMed, Medline, Embase, Cochrane Library, and Springer database was performed to identify relevant studies comparing mesh-augmentation versus suture repair of the esophageal hiatus. Data pertinent to the benefit versus risk outcomes for these techniques were extracted and compared by meta-analysis. The odd ratio (OR) and mean differences (MD) with 95% confidence intervals were calculated. Results: Eleven studies (4 randomized, 9 non-randomized) comparing mesh (n = 719) versus suture (n = 755) repair were identified. Mesh-augmentation was associated with a reduced overall recurrence rate compared to suture repair [2.6 vs. 9.4%, OR 0.23 (95% CI 0.14–0.39), P < 0.00001]. There was no significant difference in the incidence of complications (P = 0.400) between groups. Improvement in QOL measured by SF-36 was greater following biological mesh-augmentation compared to suture repair (MD = 13.68, 95% CI 2.51–24.85, P = 0.020), as well as GERD-HRQL. No differences were seen for the GIQLI scores with permanent mesh (P = 0.530). Dysphagia improvements were better following suture repair (MD = 1.47, 95% CI 0.20–2.74, P = 0.020). Conclusions: Mesh repair of HH conferred some advantages and disadvantages at short-term follow-up. Compared to a suture repair alone, mesh-augmentation might be associated with less short-term recurrences, and biological mesh was associated with improved short-term QOL. However, these advantages were offset by more dysphagia. Long-term outcomes are still needed to determine the place of mesh repair of HH.
