PRU-MHC: Policy Research Unit in Maternal Health & Care (2010 - 2018)

A population-based national study of the surgical outcomes of infants born with duodenal atresia.

This study will use BAPS-CASS to conduct a prospective, national observational investigation of the incidence, current management practices and outcomes of infants born with duodenal atresia or stenosis in the UK and Ireland. Any live-born infant with occlusion or narrowing of the duodenum associated with atresia, stenosis, duodenal web or annular pancreas presenting before 44 weeks post-conception will be included. Infants with occlusion of the duodenum caused by congenital bands associated with malrotation, intestinal volvulus, duplication cyst or malignancy will be excluded.

Selected Research Questions

  • What is the current incidence of live-born duodenal-atresia or stenosis in the UK or Ireland?
  • How are these infants managed?
  • What is the incidence of associated abnormalities in live-born infants?
  • What is the impact of comorbidity on outcome?
  • What are the outcomes for infants managed with and without a trans-anastomotic tube?
  • What are the outcomes following different surgical techniques for repair of duodenal atresia or stenosis?
