BACKGROUND
Fluoroscopically guided air reduction of intussusception is a well-accepted technique. There are only two previous reports in which US has been used to monitor pneumatic reduction.
OBJECTIVE
To assess the ability of US to monitor the success of air reduction of intussusception.
MATERIALS AND METHODS
Sonographically guided air-enema reduction of intussusception in 199 children. In phase I (11 children), the success or failure of reduction was confirmed by fluoroscopy. In phase II (188 children), complete reduction was confirmed by clinical improvement of the child and repeat sonography 1 h later showing no persistent intussusception.
RESULTS
In phase I, fluoroscopy confirmed the accuracy of US in all 11 children. In phase II, the success rate of initial reduction was 95%. Following successful reduction, US repeated 1 h later showed no recurrence of intussusception in 92%. In ten (5%) of 188, initial reduction was unsuccessful; fluoroscopically guided air reduction successfully reduced only three of these ten failures.
CONCLUSIONS
Air enema guided by US is a practical and reliable technique for the reduction of intussusception.
背景
透视引导下肠套叠空气灌肠复位术是一种被广泛接受的技术。此前仅有两篇报道使用超声监测空气灌肠复位情况。
目的
评估超声监测肠套叠空气灌肠复位成功与否的能力。
材料与方法
对199例儿童进行超声引导下肠套叠空气灌肠复位。第一阶段（11例儿童），通过透视确认复位成功或失败。第二阶段（188例儿童），根据患儿临床症状改善及1小时后重复超声检查显示无持续性肠套叠来确认完全复位。
结果
第一阶段，透视证实超声在所有11例儿童中均准确。第二阶段，初始复位成功率为95%。成功复位后，1小时后重复超声检查显示92%无肠套叠复发。188例中有10例（5%）初始复位未成功；透视引导下空气灌肠复位仅使这10例失败中的3例成功复位。
结论
超声引导下空气灌肠是一种实用且可靠的肠套叠复位技术。
