RESUMO
Objective:To evaluate the effectiveness and safety of ultrasound-guided hydrostatic reduction for pediatric acute intussusception.Methods:One thousand eight hundred and thirty patients with acute intussusception diagnosed by ultrasound in Shenzhen Children′s Hospital from September 2017 to July 2020 were treated with ultrasound-guided hydrostatic reduction method. The therapeutic effects, complications and ultrasonic features were observed.Results:Among 1 830 cases, 1 791 cases were diagnosed as primary intussusception, and 39 cases were secondary intussusception. The overall rate of successful ultrasound enema reduction were 1 780/1 830(93.7%) patients. All 50/1 830(2.7%) patients underwent surgery after unsuccessful enema reduction, including 42 cases of primary intussusception, and 8 cases of secondary intussusception. The complication of intestinal perforation occurred in 3 cases (0.16%), and there were no deaths.Conclusions:Ultrasound-guided enema reduction for pediatric acute intussusception is an effective and safe method without radiation exposure, and can be used as the preferred method for non-operative treatment of intussusception.
