Aetiology of neonatal obstruction

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Authoring team

Causes of neonatal gastrointestinal obstruction include:

  • atresia of any part of the gastrointestinal tract
  • blockage, for example with meconium
  • failure of normal peristalsis, for example in Hirschsprung's disease
  • strictures, for example secondary to necrotising enterocolitis - although this is likely to be later
  • intussusception may occasionally occur in the neonate

Later in the neonatal period other conditions should be considered, including pyloric stenosis.
