A survey of the radiological reduction of intussusception in a selection of British hospitals was performed using a questionnaire. Replies were received from radiologists working in 51 district general hospitals and 25 teaching hospitals or specialist paediatric institutions. Most district general hospitals still use barium as the sole method of reduction of intussusception. Most teaching hospitals and specialist paediatric units have changed to a pneumatic method. The contra-indications, details of patient preparation and technical details of each method varied considerably.
