Abstract: Objective：To study the application value of real-time monitoring of water pressure enema by color ultrasonography in the treatment of children with acute intussusception.Methods：Totally 616 children with acute intussusception treated in Shenyang Children's Hospital from Jan. 2012 to Jan. 2016 were selected as the research subjects. All of them were reducted by warm saline enema under real-time monitoring of color ultrasonography. For those with larger masses, low-frequency probe was used to magnify the real-time monitoring, and high-frequency probe was used for the small intussusceptions.Results:There were 609 cases of uccessfully reduction in the children with acute intussusception, the success rate being 98.8%.The reduction by water pressure enema was not successful in 7 cases, which were masses in ileocecum. Later it was confirmed by surgery that there were 4 cases of intestinal necrosis, one case of cystic intestinal duplication, one case of lymphoma of the intestinal wall, and one case of intestinal polyp.Conclusion:The real-time monitoring of water pressure enema by low- and high-frequency color ultrasonography for reduction has no radiation in the treatment of children with intussusceptions. The children feel relatively comfortable and the success rate is high, so it is a better way to manage acute intussusceptions in children.
