Comparison of outcomes following radiological reduction of intussusception with or without sedation

Background: Non-operative radiological reduction (NORR) is usually the first line treatment in pediatric ileo-colic intussusception. The aim of our study was to compare outcomes of NORR with or without sedation. Methods: All patients undergoing to contrast enema NORR for intussusception between 01.01.2015 to 31.12.2020 in two hospitals were included: in one centre patients were sedated (A) while in the other patients were awake (B). Primary outcome was the rate of radiological reduction. Secondary outcomes were length-of-stay, complications and recurrence rate. Results: Seventy-seven and 49 patients were included in group A and B respectively. Successful reduction rate was 72.7% in group A and 61.2% in group B (P>0.05). There were no complications related to the procedure among the 2 groups. Adverse events to sedation were observed in 3 patients. Conclusions: NORR has similar success rate when performed under sedation or awake, despite the former being graved by additional anesthesiologic risks and thus warrant careful indications.
