Process Management of Intussusception in Children A Retrospective Analysis in China

Abstract

Objectives: This was a retrospective analysis of the epidemiological features of pediatric intussusception, the effects of different management strategies and the factors affecting successful reduction. Methods: Using our hospital database, data on pediatric intussusception from January 2019 to December 2020 were extracted for analysis, including demographic data, size of intussusception, treatment method, and effects. Results: The number of children diagnosed with intussusception was 726 (782 episodes). In all, 394 (54.27%) of these children were male. The male to female ratio was 1.19:1. The peak of the onset age was between 3 and 4 years. In the single intussusception group, the successful reduction rate of cleansing enemas was 65.25%, that of air enemas was 95.80%, and that of B-ultrasound–guided hydrostatic enemas (B-USGHEs) was 96.04%. In the multiple intussusceptions group, the successful reduction rate of cleansing enemas was 43.9%, air enemas were 75%, and B-USGHE was 57.6%. There were no significant differences between the air enema and B-USGHE groups. The diameter and length were related factors influencing successful reduction (P ≤ 0.05). Fifty-three (7.53%) children had recurrent intussusception within 4 years, and all of them were following successful enemas. Thirty-one (3.40%) episodes were found to have spontaneously reduced. Five patients (0.7%) underwent surgery after the failure of air enemas or B-USGHE. Conclusions: Pediatric intussusception in our region showed a sex ratio difference and age difference of onset. For single intussusceptions and multiple intussusceptions, the successful reduction rate of cleansing enemas means that some children may avoid radiation exposure. The diameter and length of intussusception were related factors influencing successful reduction in cleansing enema. There were no significant differences in successful reduction between air enemas and B-USGHE. Most recurrent intussusceptions can still be reduced, avoiding surgery.
