Introduction: The introduction of minimally invasive surgery (MIS) for repair of congenital diaphragmatic hernias (CDH) has reduced postoperative length of stay, postoperative opioid consumption, and provided a more esthetic repair. In adult abdominal surgery, minimally invasive techniques have been associated with decreased long-term rates of small bowel obstruction (SBO), although it is unclear if this benefit carries over into the pediatric population. Our objective was to evaluate the rates of SBO following open versus MIS CDH repair.

Material and methods: Infants who underwent CDH repair between 2010 and 2021 were identified using the PearlDiver Mariner database. Kaplan-Meier curves and Cox proportional hazards models were used to evaluate time to SBO by surgical approach (MIS versus open) while adjusting for mesh use, patient sex, and length of stay.

Results: Of 1033 patients that underwent CDH repair, 258 (25.0%) underwent a minimally invasive approach. The overall rate of SBO was 7.5% (n = 77). Rate of SBO following MIS repair was lower than open repair at 1 y (0.8% versus 5.1%), 3 y, (2.3% versus 9.0%), and 5 y (4.4% versus 10.1%, P = 0.004). Following adjustment, the rate of SBO following MIS repair remained significantly lower than open repair (adjusted hazard ratio: 0.37, 95% confidence interval: 0.18, 0.79).

Conclusions: Following CDH repair, long-term rates of SBO are lower among patients treated with MIS approaches. Long-term risk of SBO should be considered when selecting surgical approach for CDH patients.
