    Abstract:
    PURPOSE: Quantify short-term outcomes associated with initial surgery [laparotomy (LAP) vs. peritoneal drain (PD)] for necrotizing enterocolitis (NEC) in extremely-low-birth-weight (ELBW) infants. METHODS: Using the Children's Hospitals Neonatal Database, we identified ELBW infants <32 weeks' gestation with surgical NEC (sNEC). Unadjusted and multivariable regression analyses were used to estimate the associations between LAP (or PD) and death/short bowel syndrome (SBS) and length of stay (LOS). RESULTS: LAP was the more common initial procedure for sNEC (n = 359/528, 68%). Infants receiving LAP were older and heavier. Initial procedure was unrelated to death/SBS in both bivariate (LAP: 43% vs PD: 46%, p = 0.573) and multivariable analyses (OR = 0.89, 95% CI = 0.57, 1.38, p = 0.6). LAP was inversely related to mortality (29% vs. 41%, p < 0.007) in bivariate analysis, but not significant in multivariable analysis accounting for markers of preoperative illness severity. However, the association between LAP and SBS (14% vs. 5%, p = 0.012) remained significant in multivariable analyses (adjusted OR = 2.25, p = 0.039). LOS among survivors was unrelated to the first surgical procedure in multivariable analysis. CONCLUSION: ELBW infants who undergo LAP as the initial operative procedure for sNEC may be at higher risk for SBS without a clear in-hospital survival advantage or shorter hospitalization. LEVEL OF EVIDENCE: Level II.
