Effectiveness and safety of ultrasound-guided hydrostatic reduction for children with acute intussusception

OBJECTIVE: This study aims to explore the effectiveness and safety of the new-type ultrasound-guided hydrostatic reduction for children with acute intussusception. METHODS: The clinical data of 364 children with primary acute intussusception who underwent nonsurgical reduction in our hospital between January 2016 and May 2019 were retrospectively analyzed. Among the 364 children, 119 formed the hydrostatic reduction group. There were 89 males and 30 females, and the average age of admission was 25.13 ± 1.43 months. Among the pneumatic reduction group of 245 patients, there were 163 males and 82 females. The average age of admission was 22.47 ± 1.52 months. The reduction rate, length of stay, and perforation rate were compared between the two groups. RESULTS: Univariate analysis showed that the reduction rate in the hydrostatic group (94.96%) was higher than in the pneumatic group (85.31%) (p = 0.007), and the hospital stay (2.76 ± 0.15 days) of the hydrostatic reduction group was shorter than that of the pneumatic reduction group (3.56 ± 0.35 days) (p = 0.038). In children with intussusception time >48 h, the reduction rate was 95.45% in the hydrostatic reduction group and 86.20% in the pneumatic reduction group. CONCLUSION: The new-type ultrasound-guided hydrostatic reduction has a higher reduction rate in the treatment of acute intussusception in children results in a shortened hospital stay, It is effective, safe, and avoids radiation exposure.
