Background
Ventral hernia repair is common in the expanding aging population, but remains challenging due to their frequent comorbidities. The purpose of this study is to compare the surgical outcomes of open vs. laparoscopic ventral hernia repair in elderly patients.
Methods
Patients ≥ 65 years of age that underwent elective open or laparoscopic ventral hernia repair were identified from the American College of Surgeons National Surgical Quality Improvement Project (NSQIP) database. To reduce potential selection bias, propensity scores were created for the likelihood of undergoing laparoscopic surgery based on patients’ demographics and comorbidities. Patients were matched based on the logit of the propensity scores. Thirty-day surgical outcomes were compared after matching using Chi-square test for categorical variables and the Wilcoxon Rank-Sum test for continuous variables.
Results
35,079 (71.1%) and 14,270 (28.9%) patients underwent open and laparoscopic ventral hernia repairs, respectively. Laparoscopic surgery was associated with a lower overall morbidity (5.9% vs. 9.1%; p < 0.001) compared to open repair. The incidence of surgical site infections (1.1% vs. 3.5%; p < 0.001), post-operative infections (2.7% vs. 3.6%; p < 0.001), and reoperation (1.7% vs. 2.1%; p = 0.009) were all lower after laparoscopic repair. All other major surgical outcomes were either better with laparoscopy or comparable between both treatment groups except for operative time.
Conclusion
Although open surgery remains the most prevalent in the elderly population, the results of this study suggest that laparoscopic surgery is safe and associated with a lower risk of overall morbidity, surgical site infections, and reoperation.
