The efficacy of abdominal ultrasound combined with superficial ultrasound in the diagnosis of pediatric intussusception
腹部超声联合浅表超声对小儿肠套叠诊断的效果

摘要

目的 分析腹部超声联合浅表超声对小儿肠套叠诊断的效果。方法 选取2022年1月-2024年12月期间，本院收治的150例疑似肠套叠患儿为研究对象，所有患儿均进行腹部超声检查、浅表超声检查、二者联合检查，并进行超声监测下水压灌肠检查，且以此检查结果作为金标准。对比不同检查方式的检查结果、诊断效能。结果 超声监测下水压灌肠检查检出阳性135例，常规腹部超声检出阳性124例，浅表超声检出阳性127例，联合检查检出阳性134例。联合检查的特异度显著高于腹部超声与浅表超声检查，且联合检查的准确度、阳性预测值，均明显高于腹部超声检查，差异均有统计学意义（P＜0.05）。结论 采用腹部超声联合浅表超声对小儿肠套叠进行诊断，具有更佳的诊断效能，可获取更加准确的诊断结果。

Abstract

Objective Effect of combined abdominal and superficial ultrasound in the diagnosis of pediatric intussusception.
Methods A total of 150 children suspected of intussusception admitted to our hospital from January 2022 to December 2024 were selected as the study subjects. All children underwent abdominal ultrasound, superficial ultrasound, combined ultrasound examinations, and hydrostatic enema under ultrasound guidance, with the latter results serving as the gold standard. The diagnostic outcomes and efficacy of different examination methods were compared.
Results Hydrostatic enema under ultrasound guidance detected 135 positive cases, conventional abdominal ultrasound identified 124 positive cases, superficial ultrasound detected 127 positive cases, and the combined examination identified 134 positive cases. The specificity of the combined examination was significantly higher than that of abdominal ultrasound and superficial ultrasound alone. Additionally, the accuracy and positive predictive value of the combined examination were significantly higher than those of abdominal ultrasound alone, with statistically significant differences (P < 0.05).
Conclusion   The combined use of abdominal and superficial ultrasound for the diagnosis of pediatric intussusception demonstrates superior diagnostic efficacy and provides more accurate diagnostic results.
