Manual-assisted pressure reduction versus pressure reduction alone for intussusception in pediatric patients: a case-control study

Abstract

Abstract Purpose: The aim of this present study was to compare the effectiveness of combined manual-assisted reduction and pneumatic/hydrostatic reduction versus pneumatic/hydrostatic reduction alone in treating pediatric patients with intussusception. Methods: Children suffered from intussusception who were treated by pneumatic/hydrostatic reduction with or without manual assistance between January 2019 and January 2021 were retrospectively analyzed. According to the method of reduction, the patients were grouped as MPH group (combination of pneumatic/hydrostatic reduction and manual assistance) and PH group (the pneumatic/hydrostatic reduction alone). The data collected included the demographic information, clinical symptoms, abdominal signs, investigations, success rate of reduction and details of failure cases. Results: A total of 751 children were finally included in the analysis, including 380 patients in the PH group and 371 patients in the MPH group. There were no significant differences in baseline characteristics between the PH group and the MPH group. The time of radiation exposure time and reduction in PH group (155.53±30.34 s, 267.71±40.17 s, respectively) were significantly higher than those in MPH group (112.67±30.29 s, 222.69±53.18 s, respectively) (p <0.001). While the success rate of reduction in MPH group (363 cases, 97.84%) was significantly higher than that in PH group (361 cases, 95.00%) (p =0.036). There were no statistical differences in perforation rate and recurrence rate between the two groups. Conclusion: Pneumatic/hydrostatic reduction combined manual assistance can increase the success rate of reduction, decrease the time of radiation exposure and and will not increase the incidence of complications, which is worth promoting in clinical practice.
