BACKGROUND/AIMS: Esophageal high-resolution manometry (HRM) enables the comprehensive evaluation of the esophageal motor function. However, protocols are not uniform and clinical practices vary widely among institutions. This study aims to understand the current HRM practice in Korea.
The survey was sent via email through the Korean Society of Neurogastroenterology and Motility. The questions covered descriptive information, preparation, techniques, analysis, and reporting of esophageal HRM.
The survey was completed in 32 (74.4%) out of 43 centers, including 24 tertiary and 8 secondary referral centers. Of the 32 centers, 25 (78.1%) performed HRM in a sitting position, while 7 centers (21.9%) reported performing HRM in a supine position. All the centers utilized single wet swallows as a standard, but the volume, frequency, and interval between swallows varied widely. Sixteen centers (50.0%) applied adjunctive tests, including multiple rapid swallows (n = 16) and rapid drink challenges (n = 9). Parameters assessed and documented in the report were similar. In addition to the assessment of the esophagogastric junction and esophageal body, 27 centers (84.8%) and 18 centers (56.3%) included measurements for the upper esophageal sphincter and the pharynx, respectively, in the HRM protocol.
We found a variation in the available HRM practice among centers, even though they broadly agreed in the data analysis. Efforts are needed to develop a standardized protocol for HRM measurement.
背景/目的：食管高分辨率测压（HRM）能够全面评估食管运动功能。然而，相关协议并不统一，各机构的临床实践差异很大。本研究旨在了解韩国目前的HRM实践情况。
通过韩国神经胃肠病学和动力学会以电子邮件方式发送调查问卷。问题涵盖食管HRM的描述性信息、准备工作、技术、分析和报告。
43个中心中有32个（74.4%）完成了调查，其中包括24个三级转诊中心和8个二级转诊中心。在这32个中心中，25个（78.1%）采用坐位进行HRM，而7个中心（21.9%）报告采用仰卧位进行HRM。所有中心均以单次湿吞咽作为标准，但吞咽的体积、频率和间隔差异很大。16个中心（50.0%）应用了辅助测试，包括多次快速吞咽（n = 16）和快速饮水试验（n = 9）。报告中评估和记录的参数相似。除了评估食管胃交界处和食管体部外，分别有27个中心（84.8%）和18个中心（56.3%）在HRM方案中纳入了对食管上括约肌和咽部的测量。
我们发现各中心之间现有的HRM实践存在差异，尽管它们在数据分析方面大致达成一致。需要努力制定标准化的HRM测量方案。
