Risk factors of recurrent associated with children intussusception after hydrostatic reduction enema guided by ultrasonography / 中国介入影像与治疗学

ABSTRACT

Objective: To observe the risk factors of recurrence of children intussusception after ultrasound-guided hydrostatic reduction of intussusception with saline enema (UGHSE). Methods: Clinical data of 92 intussusception cases underwent UGHSE were retrospectively analyzed, including 50 cases with recurrence of intussusception (recurrence group) and 42 cases without recurrence (non-recurrence group). Logistic regression equation was used to analyze the risk factors of recurrence of children intussusception after UGHSE. The ROC curve was further evaluated to predict the accuracy of various factors in predicting the recurrence. Results: Blood stool, secondary factors of intussusception, the maximum diameter of intussusception "concentric circles", blood flow signal of intussusception intestinal wall and seroperitoneum were all significantly different between 2 groups (all P<0.05), and all the above factors were risk factors for recurrent intussusception (all P<0.05). Taken the maximum diameter of intussusception "concentric circles" = 35 mm as the cut-off value, the AUC for predicting recurrence of intussual recombination was 0.87, higher than that of the other factors (all P<0.05). Conclusion: The maximum diameter of intussusception "concentric circles" ≥35 mm, blood stool, seroperitoneum, no blood flow signal of intussusception intestinal wall and secondary factors of intussusception are important risk factors for recurrence of children intussusception after UGHSE.
