PURPOSE
The KidZ Health Castle Formula (KHC-F) was developed to improve the positioning of multichannel intraluminal impedance-pH probes (MII-pH). We hypothesized that the updated formula KHC-Fv2 would performs better than the original formula. This study aimed to evaluate the reliability of KHC-Fv2.
METHODS
A prospective cohort study was conducted to assess MII-pH probe positioning in patients aged 1 month to 18 years. Margins of error within 1 cm above or below the target position, as determined using KHC-Fv2 and compared with fluoroscopy, were accepted.
RESULTS
Eighty-four children were included in the study. The mean difference between the KHC-Fv2 and target positions was +0.25 cm cranially. The KHC-Fv2 insertion length fell within the accepted difference of ±1 cm of the target position in 67.9% of the children. This percentage increased in infants under 1 year of age (79.5%) or shorter than 100 cm (74.0%) in height.
CONCLUSION
KHC-Fv2 demonstrated strong agreement with correct positioning and significantly reduced the need for a second radiologic control after probe repositioning, particularly in infants or children shorter than 100 cm.
目的
开发儿童健康城堡公式（KHC-F）以改善多通道腔内阻抗-pH探头（MII-pH）的定位。我们假设更新后的公式KHC-Fv2比原始公式表现更好。本研究旨在评估KHC-Fv2的可靠性。
方法
进行了一项前瞻性队列研究，以评估1个月至18岁患者的MII-pH探头定位。使用KHC-Fv2确定并与荧光透视法比较，目标位置上下1厘米内的误差范围被接受。
结果
84名儿童纳入研究。KHC-Fv2与目标位置之间的平均差异为颅骨方向上+0.25厘米。KHC-Fv2的插入长度在67.9%的儿童中落在目标位置±1厘米的可接受差异范围内。1岁以下婴儿（79.5%）或身高低于100厘米（74.0%）的儿童中这一百分比增加。
结论
KHC-Fv2与正确定位显示出高度一致性，并显著减少了探头重新定位后二次放射学检查的必要性，尤其是在身高低于100厘米的婴儿或儿童中。
