Ultrasound guided hydrostatic enema reduction of ileocolic intussusception: a safe and effective technique

Abstract

AbstractBackgroundCurrently, the primary management of ileocolic intussusception in children is usually by non‐operative image‐guided enema reduction. In most centres around the world especially in Australasia the predominant technique is the pneumatic reduction under fluoroscopic guidance. At our institution, we have been performing ultrasound‐guided hydrostatic reduction since 2012.This is an audit to determine the efficacy and safety of ultrasound‐guided hydrostatic reduction for intussusception.MethodsFollowing ethics approval, a retrospective review of all patients presenting to our institution with intussusception and subsequently undergoing hydrostatic reduction over a period of 9 years (2012 to–2020) was performed. The parameters studied included (i) successful reduction, (ii) recurrence, (iii) need for surgery and (iv) lead point at surgery.ResultsThe mean age at presentation was 12 months. One hundred and eight children were diagnosed to have ileocolic intussusception. One hundred and six underwent ultrasound‐guided hydrostatic reduction with successful reduction in 96 (90.5%) patients. Reduction was unsuccessful in 10 patients (9.5%). Of these eight were noted to have a pathological lead point (four—Meckel's diverticulum and four—Lymphoma) at the time of the surgery. The intussusception recurred in six patients (6.25%) within 24 h. No reduction related perforation occurred during the study period.ConclusionUltrasound‐guided hydrostatic reduction is a safe and effective technique for managing intussusception as it allows continuous monitoring of the reduction of the intussusception without exposing the children to ionizing radiation.
