Intussusception reduction methods in daily practice—a survey by the European Society of Paediatric Radiology Abdominal Imaging Taskforce

BackgroundImage-guided intussusception reduction has been practised internationally for many decades. The use of different modalities, delayed repeat attempts, and sedation/anaesthesia are unknown.ObjectiveTo survey the practice of image-guided intussusception reduction.Materials and methodsA 20-point questionnaire created by the European Society of Paediatric Radiology (ESPR) Abdominal Imaging Taskforce was distributed via the ESPR members’ mailing list and shared on social media between 28 March and 1 May 2023.ResultsThere were 69 responses from 65 worldwide institutions, with a mean of 18 intussusception reductions performed per year: 55/69 (80%) from 52 European institutions and 14/69 (20%) from 13 institutions outside of Europe. European centres reported using 19/52 (37%) fluoroscopy, 18/52 (35%) ultrasound, and 15/52 (28%) a mixture of both, with 30/52 (58%) offering a delayed repeat at 15 min to 24 h. Non-European centres reported using 5/13 (39%) fluoroscopy, 6/13 ultrasound (46%), and 2/13 (15%) a mixture of both, with 9/13 (69%) offering a delayed repeat attempt. Sedation or analgesia was used in 35/52 (67%) of European and 2/13 (15%) non-European institutions.ConclusionThere is wide variation in how image-guided intussusception reduction is performed, and in the use of sedation/anaesthesia.
