Purpose:We retrospectively investigated cases with intussusception for determining new ultrasonographic findings that can predict failure of enema reduction in pediatric idiopathic intussusception.
Subjects and Methods:We retrospectively reviewed 51 consecutive patients with intussusception who underwent ultrasonography examinations before enema reduction at our institution between February 2003 and April 2018. We investigated several findings related to the size of the intussusceptum and compared these between the group with reduction success and the group with reduction failure to determine whether the findings could be significant predictors for the failure of nonoperative reduction.
Results and Discussion:All novel findings were not significant, but the previously reported finding of “trapped fluid” was significantly different between the groups. The severity of poor blood perfusion in the intussusceptum may be related to nonoperative reduction failure, and the finding of trapped fluid is associated with more severe perfusion failure than other factors. Our findings also indicated that larger mesenchymal tissue in the intussusceptum tended to be associated with reduction failure, although this was not significant.
Conclusion:Ultrasonographic findings related to the size of the intussusceptum were not significantly predictive for failure of intussusception reduction. However, the trapped fluid sign may be more indicative of poor perfusion in the intussusceptum than other findings.
