Swallowing difficulty is considered one of the nonspecific symptoms that many patients with laryngopharyngeal reflux complain of. However, the relationship between laryngopharyngeal reflux and swallowing problems is not clear. The purpose of this work is to explore correlation between swallowing-related problems and laryngopharyngeal reflux (LPR) in a group of patients diagnosed with oropharyngeal pH monitoring and to study the effect of laryngopharyngeal reflux on the patients' self-perception of swallowing problems.
44 patients complaining of reflux-related problems were included in the study. Patients underwent 24-hour oropharyngeal pH monitoring and were divided into positive and negative LPR groups based on the pH monitoring results. All patient filled out the Dysphagia Handicap Index (DHI) and Reflux Symptom Index (RSI) questionnaires. Comparison was made between the positive and negative LPR groups regarding the results of the DHI and RSI ratings. Also, correlation between DHI scores, RSI scores, and pH monitoring results was studied.
Significant difference was reported between positive and negative LPR groups regarding DHI scores, RSI scores, and overall rating of swallowing difficulty. There was significant correlation demonstrated between DHI scores, RSI scores, and 24-hour oropharyngeal pH results.
Laryngopharyngeal reflux appears to have a significant impact on patients' self-perception of swallowing problems as measured by DHI.
吞咽困难被认为是许多喉咽反流患者所抱怨的非特异性症状之一。然而，喉咽反流与吞咽问题之间的关系尚不清楚。本研究的目的是探讨一组经口咽pH监测确诊的患者中，吞咽相关问题与喉咽反流（LPR）之间的相关性，并研究喉咽反流对患者吞咽问题自我认知的影响。
44名抱怨反流相关问题的患者纳入本研究。患者接受24小时口咽pH监测，并根据pH监测结果分为LPR阳性组和阴性组。所有患者均填写吞咽障碍 handicap指数（DHI）和反流症状指数（RSI）问卷。比较LPR阳性组和阴性组在DHI和RSI评分结果上的差异。此外，还研究了DHI评分、RSI评分与pH监测结果之间的相关性。
LPR阳性组和阴性组在DHI评分、RSI评分和吞咽困难总体评分方面存在显著差异。DHI评分、RSI评分与24小时口咽pH结果之间存在显著相关性。
通过DHI测量，喉咽反流似乎对患者的吞咽问题自我认知有显著影响。
