External manual reduction of paediatric idiopathic ileocolic intussusception with US assistance: a new, standardised, effective and safe manoeuvre



The ultimate goal in the management of paediatric ileocolic intussusception is to achieve non-operative reduction and therefore patient cure. The standard non-surgical treatment consists of enema (air or liquid media).


The purpose of this study is to present external manual reduction for paediatric ileocolic intussusception. We present a new manoeuvre that is standardised, simple, safe and effective for the radiologist in the non-surgical management of this pathology.

Materials and methods

External manual reduction is performed under sedation. Execution of the manoeuvre is detailed and illustrated. The procedure was carried out 15 times in 13 paediatric patients with idiopathic ileocolic intussusception.


Complete reduction exclusively by external manual reduction was accomplished on 12 occasions (80%). In the remaining three procedures, partial reduction to the cecum was obtained. Subsequent enema achieved complete reduction in two. Overall non-surgical reduction rate was 93%.


External manual reduction is a radiation-free, safe and effective procedure. In case of incomplete reduction, it facilitates enema performance. External manual reduction incorporates and additional initial step in the non-surgical reduction of intussusception and should be considered a first-line procedure.
