- Abstract
Introduction: Sufficient overlap of mesh beyond the borders of a ventral hernia helps prevent hernia recurrence. Guidelines from the European Hernia Society and American Hernia Society recommend ≥ 2 cm overlap for open repair of < 1-cm hernias, ≥ 3-cm overlap for open repair of 1-4-cm hernias, ≥ 5-cm overlap for open repair of > 4-cm hernias, and ≥ 5-cm overlap for all laparoscopic ventral hernia repairs. We evaluated whether current practice reflects this guidance., Methods: We used the Michigan Surgical Quality Collaborative Hernia Registry to evaluate patients who underwent elective ventral and umbilical hernia repair between 2020 and 2022. Mesh overlap was calculated as [(width of mesh - width of hernia)/2]. The main outcome was "sufficient overlap," defined based on published EHS and AHS guidelines. Explanatory variables included patient, operative, and hernia characteristics. The main analysis was a multivariable logistic regression to evaluate the association between explanatory variables and sufficient mesh overlap., Results: 4178 patients underwent ventral hernia repair with a mean age of 55.2 (13.9) years, 1739 (41.6%) females, mean body mass index (BMI) of 33.1 (7.2) kg/m
2 , and mean hernia width of 3.7 (3.4) cm. Mean mesh overlap was 3.7 (2.5) cm and ranged from - 5.5 to 21.4 cm. Only 1074 (25.7%) ventral hernia repairs had sufficient mesh overlap according to published guidelines. Operative factors associated with increased odds of sufficient overlap included myofascial release (adjusted odds ratio [aOR] 5.35 [95% CI 4.07-7.03]), minimally invasive approach (aOR 1.86 [95% CI 1.60-2.17]), and onlay mesh location (aOR 1.31 [95% CI 1.07-1.59]). Patient factors associated with increased odds of sufficient overlap included prior hernia repair (aOR 1.59 [95% CI 1.32-1.92])., Conclusion: Although sufficient mesh overlap is recommended to prevent ventral hernia recurrence, only a quarter of ventral hernia repairs in a state-wide cohort of patients had sufficient overlap according to evidence-based guidelines. Factors strongly associated with sufficient overlap included myofascial release, mesh type, and laparoscopic repair., (© 2023.
