Karila K, et al. - In this retrospective observational study, developments in the outcomes of surgically treated necrotizing enterocolitis (NEC) and spontaneous intestinal perforation (SIP) in the two largest Finnish neonatal intensive care units (NICU) were assessed. Researchers included 225 patients (NICU A 131 and NICU B 94) with NEC in 142 (63%) and SIP 83 (37%). They compared three-month survival during 1986–2000 with 2001–2014 and predictors of mortality. From the early (1986–2000) to the late (2001–2014) study period, a significant improvement in overall survival was observed. The treating neonatal intensive care unit was the strongest predictor for mortality.
