Infant Feeding: Formula Feeding

Abstract

We sought to describe long-term outcomes of infants with severe surgical necrotizing enterocolitis (NEC).Data were collected on infants with surgical NEC (2009–2018). Severe surgical NEC was defined by extensive bowel loss with residual bowel length < 30 cm, and “NEC totalis” was identified per operative report. Post-operative management and long-term outcomes were assessed, including enteral autonomy, severe neurodevelopmental disability, and educational attainment.Of 268 infants with surgical NEC, 41 (15%) had severe surgical NEC, and 14/41 were identified as “NEC totalis”. Zero severe NEC vs. 8 (57%) “NEC totalis” patients were placed on comfort measures following initial surgery (p < 0.001). Twenty-five patients (93%) with severe NEC survived vs 3/6 with “NEC totalis” (p < 0.001). The 28 survivors (68%) were followed for a median (IQR) duration of 8(4,10) years. Nine (32%) with severe NEC were weaned from parenteral nutrition. Eight (29%) had ≥ 1 marker for severe neurodevelopmental disability, and 11/16(69%) (7–16 years) were attending school at last follow-up.Long-term survival is excellent following initial discharge, and achievement of enteral autonomy is feasible in patients with severe surgical NEC. The majority of patients who survive do not have severe neurodevelopmental disability and participate in school. Given current survivals and outcomes, focus on measured residual bowel length may be more appropriate than the subjective term “NEC-totalis.”Prognosis Study.Level II.
