Maximizing mesh mileage: evaluating the long-term performance of a novel hybrid mesh for ventral hernia repair

The objective of this study is to evaluate the safety and long-term outcomes of GORE Synecor™ in ventral hernia repair (VHR).

This retrospective, single-center case review analyzed outcomes in patients who underwent VHR with Synecor from May 2016 to December 2022. Primary outcomes were hernia recurrence and mesh infection rates. Secondary outcomes were 30-day morbidity, 30-day mortality, 30-day readmission, re-operation, surgical-site infection (SSI) and occurrence (SSO) rates, and occurrences requiring intervention (SSOI).

278 patients were identified. Mean follow-up was 24.1 (0.2-87.1) months. Mean hernia defect size was 63.4 (± 77.2) cm². Overall hernia recurrence and mesh infection rates were 5.0% and 1.4% respectively. No mesh infections required full explantation. We report the following overall rates: 13.3% 30-day morbidity, 4.7% 30-day readmission, 2.9% re-operation, 7.2% SSI, 6.1% SSO, and 2.9% SSOI. 30-day morbidity was significantly higher in non-clean (42.1% vs 11.2%, p < 0.01), onlay (OL) mesh (37.0% vs preperitoneal (PP) 16.4%, p = 0.05 vs retrorectus (RR) 15.0%, p < 0.05 vs intraperitoneal (IP) 5.2%, p < 0.001), and open cases (23.5% vs 3.1% laparoscopic vs 4.4% robotic, p < 0.01). SSI rates were significantly higher in non-clean (31.6% vs 5.4%, p < 0.001), OL mesh (29.6% vs RR 11.3%, p < 0.05 vs PP 5.5%, p < 0.01 vs IP 0.0%, p < 0.001), and open cases (15.2% vs 0% laparoscopic vs 0% robotic, p < 0.05).

Long-term performance of a novel hybrid mesh in VHR demonstrates a low recurrence rate and favorable safety profile in various defect sizes and mesh placement locations.
