Children’s Surgery Outcome Reporting

What is it?

The Children’s Surgery Outcome Reporting (CSOR) research project is a five-year programme looking at the surgical outcomes for children affected by 6 conditions.

These conditions are:

  • Oesophageal Atresia/Tracheo-Oesophageal Fistula (OA/TOF)
  • Gastroschisis
  • Hirschsprung’s Disease (HD)
  • Congenital Diaphragmatic Hernia (CDH)
  • Necrotising Enterocolitis (NEC)
  • Posterior Urethral Valves (PUV)

What are the aims?

The study is investigating whether it is possible to reduce unwarranted variation in the health and wellbeing of children undergoing early surgery at different hospitals in England and Scotland.


Across the UK, there is significant variation in the way children are treated for surgical conditions (conditions that usually, but not always, require an operation). However, we do not know which aspects of these variations affect how successfully children are treated. Producing evidence requires collecting reliable information about how children are currently treated, and linking this information to information about their long-term health and wellbeing.

The team

The CSOR programme is being led by Professor Marian Knight and Mr Simon Kenny. Mr Benjamin Allin is responsible for the day-to-day management of the programme and integration of the six workstreams.
