Ultrasound-guided hydrostatic reduction versus fluoroscopy-guided air reduction for pediatric intussusception: a multi-center, prospective, cohort study

Abstract Background Intussusception is the most common abdominal emergency in children. The first line treatment of uncomplicated pediatric intussusception enema reduction. Until now, there have been no multi-center studies comparing effectiveness and safety UGHR FGAR intussusception. aim this study was to compare two commonly used methods intussusception: ultrasound-guided hydrostatic reduction (UGHR) fluoroscopy-guided air (FGAR). Methods From November 1, 2017 October 31, 2018, we conducted a multi-center, prospective, cohort study. Children diagnosed with four large Children’s Medical Centers China were divided into groups. Stratified analysis subgroup for further comparison. success recurrence rates evaluate perforation rate Results A total 2124 cases met inclusion criteria (UGHR group: 1119 cases; 1005 cases). group higher than (95.80%, 9.28% vs. 93.13%, 10.65%) ( P < 0.05, > 0.05), respectively. 0.36% compared 0.30% 0.05). Subgroup showed patients onset time between 12 24 h (95.56% 90.57%) Of aged 4 months, also (95.77% 91.60%) symptom bloody stool (91.91% vs 85.38%) Conclusions are safe, nonsurgical acute superior FGAR, radiation risk, its higher, without difference rate, especially 4–24 months. Level evidence II.
