ABSTRACT
INTRODUCTION: Bronchopulmonary dysplasia (BPD) is a common respiratory morbidity among premature infants. Nissen fundoplication may be performed on infants with BPD to protect the lungs from gastroesophageal reflux-related aspiration, but the indications and benefits associated with fundoplication are not well-defined. This study evaluated associations of Nissen with clinical outcomes in infants with severe BPD (sBPD), using propensity score matching to minimize bias and confounding.
METHODS: Infants ≤31 wk gestational age with sBPD (grade 2-3) admitted to a single neonatal intensive care unit (NICU) between January 2016 and October 2021 were included. Patients with sBPD who underwent Nissen fundoplication during initial NICU admission were propensity score-matched at a 1:2 ratio with control patients who did not undergo Nissen (no-Nissen). Outcomes were compared, including time to freedom from respiratory support (defined as ≤2 L nasal cannula), time to initial NICU discharge, and incidence of hospital readmission or death within 1 y postdischarge.
RESULTS: After propensity score matching, 18 Nissen infants were compared with 30 no-Nissen infants. The Nissen group trended toward longer time to freedom from respiratory support (median 105 versus 70 d, P = 0.09), and had longer initial hospital stays (188 versus 111 d, P = 0.002), more 1-y hospital readmissions (83% versus 50%, P = 0.04), and more tracheostomies (28% versus 0%, P = 0.005). Mortality during first-year postdischarge was similar (6% versus 10%, P = 1.0).
CONCLUSIONS: Despite adjustment for confounding variables, Nissen fundoplication was associated with prolonged support and greater resource utilization among infants with sBPD. Prospective studies are needed to clarify indications for fundoplication in this population.
