Abstract

Background/aims: The Reflux Symptom Index (RSI) is a questionnaire that evaluates the severity of extra-esophageal symptoms and is one of the most widely used measures to evaluate LPR. This study assessed the validity and reliability of the RSI questionnaire in Bahasa Indonesia and investigated the association between each extra-esophageal symptom reported in the questionnaire and the severity of erosive esophagitis as determined by endoscopic findings.

Methods: 85 adult patients with GERD symptoms had an upper endoscopy examination and were asked to complete the translated RSI. The validity and reliability of the questionnaire were assessed.

Results: The construct validity of the RSI translated into Bahasa Indonesia was verified with the r value of each question being higher than the crucial table value (r>0.213, p<0.05). Our questionnaire had a Cronbach alpha value of 0.81, which indicates an acceptable level of internal consistency. At least one extra-esophageal symptom was seen in 91.7% of patients with Los Angeles (LA) grade B or higher-grade esophagitis. In addition, the presence of extra-esophageal symptoms was associated with significant mucosal erosion (p=0.20). The symptoms of cough after eating or lying down and chronic cough were associated with the severity of esophageal mucosal erosion (p<0.05).

Conclusions: The version of RSI translated into Bahasa Indonesia is a valid and reliable tool for assessing extra-esophageal GERD symptoms. The occurrence of extra-esophageal symptoms in patients with typical GERD symptoms is associated with endoscopic findings of LA grade B or erosive esophagitis of higher severity.

反流症状指数翻译成印尼语的效度和信度:上内镜在评估食管外胃食管反流病症状中的作用
背景/目的:反流症状指数(RSI)是一种评价食管外症状严重程度的问卷,是评价LPR最广泛使用的指标之一。本研究评估了印尼语RSI问卷的有效性和可靠性,并调查了问卷中报告的每种食管外症状与内镜检查结果确定的糜烂性食管炎严重程度之间的关系。方法:85例有胃食管反流症状的成年患者行上颌内窥镜检查,并要求完成RSI的翻译。评估问卷的效度和信度。结果:印尼语RSI量表的结构效度得到验证,每个问题的r值均高于关键表值(r>0.213)。结论:印尼语RSI量表是评估食管外胃食管反流症状的有效、可靠的工具。有典型胃食管反流症状的患者出现食管外症状与LA级B或更严重的糜烂性食管炎的内镜检查结果相关。
