Evaluation of long-term performance of an intraperitoneal biomaterial in the treatment of ventral hernias

Abstract

Abstract Background One-year device safety and clinical outcomes of ventral hernia repair with the GORE® SYNECOR Intraperitoneal Biomaterial, a hybrid composite mesh was evaluated. Methods This retrospective, multicenter, case review analyzed device/procedure endpoints and patient-reported outcomes in patients treated for hernia repair ≥ 1 year from study enrollment. Results Included were 459 patients (with 469 ventral hernias) with a mean age of 58 ± 15 years; 77.1% met Ventral Hernia Working Group 2 (VHWG2) classification. Mean hernia size was 18.9 cm2 and 57.3% of hernias were incisional. Laparoscopic or robotic approach was utilized in 95.4% of patients. Mesh location was intraperitoneal for 75.6% and bridging repair was performed in 57.3%. Procedure-related adverse events within 30-days occurred in 5.0% of patients and included surgical site infection (SSI), surgical site occurrence (SSO), ileus, readmission, and re-operation. Procedure-related SSI or SSO events were 3.8% through 12 months. SSO events requiring procedural intervention (SSOPI) were 2.6% through 24 months. Four patients (0.9%) had confirmed hernia recurrence through the study (the mean follow-up was 32-months, range 14–53 months). Subgroup comparisons were conducted for all type recurrence; only diabetes was found to be statistically significant (p = .0506). Conclusion In this analysis, ventral hernia repair with hybrid, composite mesh results in successful outcomes in most patients. This study represents a heterogeneous patient population undergoing repair using various approaches, mesh fixation, and mesh placement locations. These data appear to confirm long-term acceptable safety and device performance with a low rate of recurrence in a predominantly VHWG2 population.
