Conservative Management of Necrotizing Enterocolitis in Newborns: Incidence and Management of Intestinal Strictures
Topic overview
Retrospective study of 126 neonates with NEC managed conservatively found 19% developed post-NEC strictures requiring delayed surgery. Most strictures occurred in the colon and were successfully treated with primary anastomosis, with favorable outcomes and minimal complications when surgery was deferred until hemodynamic stability.
Key takeaways
- 19% of neonates with conservatively managed NEC develop post-NEC strictures, typically diagnosed 38 days after the acute episode
- Two-thirds of post-NEC strictures occur in the cecum, ascending, and transverse colon; all were managed with primary anastomosis
- 25% of post-NEC strictures are asymptomatic and detected only by screening contrast enema, supporting routine surveillance imaging
- Delayed surgical intervention for post-NEC strictures allows hemodynamic stability, shorter resections, and favorable outcomes
- Conservative NEC management is feasible in 57.5% of cases, with low mortality when strictures are managed electively
