BackgroundThe decision to perform laparoscopic or open ventral hernia repair (VHR) is multifactorial. This study evaluates the impact of operative approach, BMI, and hernia size on outcomes after VHR.Study DesignThe International Hernia Mesh Registry was queried for VHR (2007-2017). A predictive algorithm was constructed, factoring the impact of BMI, hernia size, age, sex, diabetes, and operative approach on outcomes.ResultsOf the 1,906 VHRs, 58.8% were performed open, patient mean age was 54.9 ± 13.5 years, BMI was 31.2 ± 6.8 kg/m2, and defect area was 44.8 ± 88.1 cm2. Patients undergoing open VHRs were more likely to have an infection develop (3.1% vs 0.3%; p < 0.0001), but less likely to have a seroma develop (6.8% vs 15.3%; p < 0.0001) at mean follow-up 23.2 ± 12.0 months. With multivariate regression controlling for confounding variables, patients undergoing laparoscopic VHR had increased risk of seroma (odds ratio [OR] 1.78; 95% CI 1.05 to 3.03), a decreased risk of infection (OR 0.05; 95% CI 0.01 to 0.42), and had worse quality of life at 1, 6, 12, and 24 months postoperatively compared with patients undergoing open repair. Recurrent hernias were associated with subsequent recurrence (OR 2.69; 95% CI 1.24 to 5.81) and need for reoperation (OR 4.93; 95% CI 2.24 to 10.87). Multivariate predictive models demonstrated independent predictors of infection, including open approach, recurrent hernias, and low ratio of BMI to defect size.ConclusionsIdeal outcomes are dependent on both patient and operative factors. Open repair in thin patients with large defects should be considered due to reduced complications and improved quality of life. Laparoscopic repair in obese patients and recurrent hernias can decrease the associated risk of infection.Copyright © 2018 American College of Surgeons. Published by Elsevier Inc.
