Abstract

Background: Minimally invasive surgery (MIS) is increasingly used for repair of congenital diaphragmatic hernia (CDH). Reported recurrence after MIS repair varies and is limited by short follow-up and low volume. Our objective was to compare recurrence after MIS versus open repair of CDH. Materials and Methods: Infants who underwent CDH repair between 2010 and 2020 were identified using the PearlDiver Mariner database, a national patient claims data set allowing longitudinal follow-up of patients across systems. Kaplan-Meier analysis and Cox proportional hazards regression models were used to evaluate the association of surgical approach (MIS versus open) and use of a patch with time to recurrence while adjusting for comorbidities (congenital heart disease and pulmonary hypertension) and length of stay (LOS). Results: In a cohort of 629 infants, 25.6% (n = 161) underwent MIS repair with a median follow-up of 4.8 years and recurrence rate of 38.6% (n = 243). Rates of recurrence after MIS repair were lower than open (5 years: 38.6% versus 44.3%; P = .03) and higher with use of patch (5 years: 60.1% versus 40.1%; P = .02). After adjustment for comorbidities and LOS as a proxy for patient complexity, there was no significant difference in recurrence based on approach (adjusted hazard ratio [aHR]: 0.79; confidence interval [95% CI]: 0.57-1.10; P = .16) or use of patch (aHR: 1.22; 95% CI: 0.83-1.79; P = .32). Conclusions: Recurrence rates after repair of CDH were not different based on surgical approach or use of patch after adjustment. Previous data were likely biased by patient complexity, and surgeons should consider these factors in determining approach.
