The study on the value of high-frequency ultrasound in the diagnosis and treatment of intussusception in children

Abstract

Objective To study and explore the value of high-frequency ultrasound in the diagnosis and treatment of intussusception in children. Methods 90 children suspected as intussusception in our hospital from January 2015 to December 2017 were selected. All children underwent high-frequency ultrasound and X-ray examination, and ultrasound and X images were analyzed. The sensitivity, specificity, and accuracy of high-frequency ultrasound and X-ray in the diagnosis of intussusception in children were calculated and compared. The consistency between the results of high-frequency ultrasound and X-ray in the diagnosis of pediatric intussusception and the results of diagnosis were compared. Under the guidance of high frequency ultrasound, children with intussusception was treated with aero-pressor-therapy, and the therapeutic effect was observed. Results The sensitivity, specificity, and accuracy of high frequency ultrasound in the diagnosis of pediatric intussusception were 95.65%, 95.24%, 95.56%, the diagnostic sensitivity, accuracy of high frequency ultrasound were higher than those of X-ray (P 0.05). The conformance analysis showed that there was a good consistency between the results of high-frequency ultrasound and the results of diagnosis for pediatric intussusception, while the consistency between X-ray and the results of diagnosis for pediatric intussusception was not good. After aero-pressor-therapy guided by high frequency ultrasound, the success rate of pediatric intussusception reduction was 100%, without case of transfer operation. Conclusion High frequency ultrasound can make sensitive and accurate diagnosis for intussusception in children. It has high diagnostic value, can also guide aero-pressor-therapy, which is beneficial to improve the success rate of intussusception reduction.
