超声诊断和水压灌肠治疗小儿肠套叠

Ultrasound (US) Diagnosis and US-guided Hydrostatic Reduction for Intussusception in Children

目的 评价超声诊断和超声监视下水压灌肠治疗小儿急性肠套叠的方法和疗效。方法 对 1 73例可疑肠套叠患儿进行超声检查 ,发现有“同心圆”征的同时在超声监视下进行水压灌肠复位治疗。结果 超声确诊肠套叠 32例 ,诊断准确率 1 0 0 % ,其中 30例水压灌肠复位成功 ,复位成功率 93 .8%。 3例回回结型中 1例水压灌肠成功 ,2例失败改手术治疗。结论 超声诊断小儿肠套叠准确率高 ,水压灌肠复位成功率高。对回回结型超声可以确诊 。

Objective To evaluate the method and therapeutic effect of US guided hydrostatic reduction of intussusception in children. Methods US was performed in 173 out patient children with suspected intussusception. The 173 cases, diagnosed as intussusception by US (classical US doughnut sign found on US), had US guided hydrostatic reduction. Results Thirty two cases had difinite US diagnosis of intussusception. The diagnosis was 100% accurate. Of the 32 cases of intusscsception, 30 (93.8%) had successful US guided hydrostatic reduction. Three cases were diagnosed to have ileoileocolic intussusception by US; one of them had successful hydrostatic reduction; and 2 underwent surgery for failed hydrostatic reduction. Conclusions US diagnosis of intussusception is reliable and accurate and hydrostatic reduction of childhood intussusception is effective. Though ileoileocolic intussusception can be diagnosed by US, the rate of successful hydrostatic reduction is low.
