Updated KidZ Health Castle Formula for Multichannel Intraluminal Impedance-pH Monitoring Probe Positioning.
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.
期刊介绍：
Pediatric Gastroenterology, Hepatology and Nutrition (Pediatr Gastroenterol Hepatol Nutr), an official journal of The Korean Society of Pediatric Gastroenterology, Hepatology and Nutrition, is issued bimonthly and published in English. The aim of Pediatr Gastroenterol Hepatol Nutr is to advance scientific knowledge and promote child healthcare by publishing high-quality empirical and theoretical studies and providing a recently updated knowledge to those practitioners and scholars in the field of pediatric gastroenterology, hepatology and nutrition. Pediatr Gastroenterol Hepatol Nutr publishes review articles, original articles, and case reports. All of the submitted papers are peer-reviewed. The journal covers basic and clinical researches on molecular and cellular biology, pathophysiology, epidemiology, diagnosis, and treatment of all aspects of pediatric gastrointestinal diseases and nutritional health problems.
