Necrotizing Enterocolitis in Infants with Hybrid Stage 1 Palliation is Common and Difficult to Predict.

Necrotizing enterocolitis (necrotizing enterocolitis) is common in these infants, although specific risk factors have not been identified to predict those who will develop necrotizing enterocolitis.

Hypoplastic left heart syndrome accounted for 54.3% of patients.

Stage 1 necrotizing enterocolitis occurred in 42 infants (75.0%), with stage 2/3 necrotizing enterocolitis occurring in 14 infants (25.0%).

Having three or more risk factors leading to the decision to undergo HS1P was associated with development of necrotizing enterocolitis (p = 0.01).
