Neonates living with enterostomy following necrotising enterocolitis are at high risk of becoming severely underweight

Abstract

Necrotising enterocolitis (NEC) is often managed with a temporary enterostomy. Neonates with enterostomy are at risk of growth retardation during critical neurodevelopment. We examined their growth using z-score. We identified all patients with enterostomy from NEC in two neonatal surgical units (NSU) during January 2012–December 2016. Weight-for-age z-score was calculated at birth, stoma formation and closure, noting severely underweight as z < − 3, meeting the WHO criteria of being severely underweight, despite judicial use of parenteral nutrition. Applying z-score to weight measurements will allow growth trajectory to be accounted for in clinical decisions, including nutrition prescription (both enteral and parenteral), and guide timing of stoma closure.• Surgeons who target stoma closure at a certain weight risk waiting for an indefinite period of time, during which babies’ growth may falter.
