Therapeutic Effect of Multilevel Surgery on Laryngopharyngeal Reflux in Obstructive Sleep Apnea Patients: Impact on the Reflux Symptom Index and Reflux Finding Score

Objectives.Our previous study found that multilevel obstructive sleep apnea (OSA) surgery mitigated laryngopharyngeal reflux (LPR) symptoms in terms of the reflux symptom index (RSI), but no studies have investigated the impact of OSA surgery on laryngoscopic parameters. The aim of this study was to examine the clinical outcome of LPR improvement following OSA surgery, with a focus on both the RSI and the reflux finding score (RFS).Methods.Prospectively collected data from 28 patients who underwent multilevel OSA surgery from 2017 to 2021 were retrospectively analyzed. Patients were asked to complete the RSI questionnaire and underwent a laryngoscopic examination to evaluate the RFS before and after surgery. Age, height, weight, body mass index (BMI), and polysomnography data before and after surgery were also reviewed.Results.After surgery, the total RSI and RFS decreased significantly from 11.96±8.40 to 7.68±6.82 (P=0.003) and from 6.57±3.49 to 3.21±1.87 (P<0.001). The positive rates of RSI and RFS decreased from 28.6% to 17.9% and 32.1% to 0%, respectively. Significant improvements were found in the RSI subdomains of throat clearing, throat mucus, breathing difficulty, troublesome cough, and heartburn sensation, while all RFS subdomains except granuloma improved significantly. In subgroup analyses, no significant differences were found between subgroups based on age, OSA severity, or BMI.Conclusion.OSA surgery has the potential to alleviate both LPR symptoms and laryngoscopic results. Additional research integrating more objective techniques and novel treatment strategies is required to better comprehend the clinical impact of OSA surgery on LPR.     

Laryngopharyngeal reflux in obstructive sleep apnoea patients: Literature review and meta-analysis

Purpose

Laryngopharyngeal reflux (LPR) is a frequent condition in Obstructive Sleep Apnoea (OSA) patients and different studies have been published in the last years about this topic. A review of the published literature regarding LPR in OSA patients has been reported. A meta-analysis to evaluate the incidence of LPR in OSA patients and correlate LPR positivity with OSA patients' characteristics has been performed.

Study on the time-point distribution characteristics of the occurrence of laryngopharyngeal reflux北大核心CSCD

Objective To investigate the characteristics of the time-point distribution of the occurrence of laryngopharyngeal reflux (LPR) by 24-hour multichannel intraluminal impedance-pH monitoring (24 h MII-pH) and to provide guidance for the development of individualized anti-reflux strategies for LPR patients. Methods We conducted a retrospective analysis of 24 h MII-pH data from 408 patients [339 males and 69 females, aged 23-84 (55.08± 11.08) years] attending the Department of Otorhinolaryngology Head and Neck Surgery at the Sixth Medical Center of the PLA General Hospital from January 2013 to March 2020. The number of gas acid/weak-acid reflux, mixed gas-liquid acid/weak-acid reflux, liquid acid/weak-acid reflux and alkaline reflux events at different time points were recorded and statistically analyzed through SPSS 26.0 software. Results A total of 408 patients were included. Based on the 24 h MII-pH, the total positive rate of LPR was 77.45% (316/408). The type of positive gaseous weak-acid reflux was significantly higher than the remaining types of LPR (χ2=297.12, P<0.001). Except the gaseous weak-acid reflux, the occurrence of the remaining types of LPR showed a tendency to increase after meals, especially after dinner. Liquid acid reflux events occurred mainly between after dinner and the following morning, and 47.11% (57/121) of them occurred within 3 h after dinner. There was a significant positive association between Reflux Symptom Index scores and gaseous weak-acid reflux (r=0.127, P<0.01), liquid acid reflux(r=0.205, P<0.01) and liquid weak-acid reflux(r=0.103, P<0.05) events. Conclusions With the exception of gaseous weak-acid reflux events, the occurrence of the remaining types of LPR events has a tendency to increase after meals, especially after dinner. Gaseous weak-acid reflux events accounts for the largest proportion of all types of LPR events, but the pathogenic mechanisms of gaseous weak-acid reflux are needed to further investigate. ©2021 Japanese Society of Allergology.

咽喉反流伴阻塞性睡眠呼吸暂停低通气综合征患者的治疗及其咽喉反流体征评分、症状指数特点

目的 分析咽喉反流病(LPRD)伴阻塞性睡眠呼吸暂停综合征(OSAS)患者的咽喉反流体征评分(RFS)和咽喉反流症状指数(RSI)特点,探讨临床治疗效果。 方法 抽取100例LPRD患者,将其中合并有OSAS的患者作为观察组(n=39),其余作为对照组(n=61),观察两组RFS、RSI及呼吸暂停低通气指数(AHI)、血氧饱和度(SaO₂)、反流总数、总反流时间;比较治疗2个月后RSI、RFS评分。 结果 观察组RFS和RSI评分总分显著高于对照组,RFS体征差异均有统计学意义(P<0.05),咽喉反流伴OSAS患者声门下水肿、喉室消失、杓会厌襞红斑/充血、喉黏膜水肿、后联合肥厚或肿胀评分显著高于单纯的咽喉反流患者(P<0.05),RSI评分中咽喉反流伴OSAS患者呼吸困难、烧心胸痛胃酸反流评分显著高于单纯的咽喉反流患者(P<0.05);治疗后,观察组RSI评分总分高于对照组(P均<0.05),对照组在呼吸困难、烧心胸痛胃酸反流方面明显优于观察组(P<0.05)。治疗前后,两组AHI、SaO₂、反流总数比较均差异有统计学意义(P<0.05)。治疗后,观察组AHI、SaO₂均明显改善,与治疗前比较差异有统计学意义(P<0.05),两组反流总数、总反流时间改善显著,对照组优于观察组(P<0.05)。 结论 伴OSAS会加重LPRD患者咽喉反流相关症状,可能是LPRD患者治疗效果和症状改善较差的原因。     

Trends in laryngopharyngeal reflux: a British ENT survey

There is a lot of scepticism surrounding laryngopharyngeal reflux (LPR). Symptoms such as globus pharyngeus, constant throat clearing, chronic cough, idiopathic hoarseness, catarrh and choking episodes may be reflux-related. The aim of this survey was to highlight current treatment trends in LPR. Questionnaires were emailed to 260 members of the British Academy of Otolaryngology-Head and Neck surgery (BAO-HNS). Survey recipients were asked about type, duration and dose of antireflux treatment and length of follow-up appointments, if any. Finally, they were asked about awareness of any reflux symptom and reflux sign questionnaires. Survey response rate was 60%. The vast majority of the otolaryngologists surveyed believe in laryngopharyngeal reflux (90%) and more than 50% prescribe proton pump inhibitors (PPIs). The preferred duration of treatment is 2 months (37%). Only a minority will prescribe PPIs for 6 months or more. Most otolaryngologists will give the standard GORD dose (70%) (once daily) and only a few (20%) will prescribe more aggressive and prolonged doses. The commonest symptoms for which proton pump inhibitors are prescribed are globus (73%), followed by choking episodes (66%) and chronic cough (62%). If LPR is suspected, most of the otolaryngologists will follow-up the patients (61%) and approximately one third (31%) will discharge them back to the general practitioners. Only eight-percent 8% will refer to gastroenterologists. The three commonest laryngoscopic signs that makes them suspect LPR are erythema of the arytenoids (86%) or the vocal cords (57%) and granulomas (42%). The majority of the otolaryngologists (94%) do not use popular questionnaires such as the RFS or RSI. Despite the controversy surrounding laryngopharyngeal reflux, our results suggest that the majority of the otolaryngologists surveyed believe in LPR and attempt to treat it. Interesting findings are: the duration of treatment, the doses used, the length of follow-ups or the lack of, and the fact that the majority does not request any specific diagnostic tests. “symptoms and signs” questionnaires are rarely used.     

Do the laryngopharyngeal symptoms and signs ameliorate by empiric treatment in patients with suspected laryngopharyngeal reflux?

Objectives

In clinical practice, antireflux medication is given almost always empirically without pH monitorization. We aimed to evaluate the improving effect of empiric antireflux treatment on layngopharyngeal symptoms and signs in patients with gastroesophageal reflux (GER) and suspected laryngopharyngeal reflux (LPR) according to reflux symptom index (RSI) and reflux finding score (RFS).

Methods

GER was determined by esophagogastroduedonoscopy and biopsy in 127 patients. RSI and RFS were calculated for each patient. The patients with a pathology other than LFR which may be responsible from laryngopharyngeal symptoms and signs were excluded from the study. Fifty patients whom were thought to have LPR according to RSI and RFS comprised the study group. After 12-weeks of antireflux treatment, RSI and RFS were calculated again. The statistical analyses were made according to the changes in the severity and frequency of each symptom and sign.

Results

There was statistically significant improvement in RSI and RFS after treatment when compared with initial scores. There was statistically significant improvement in severity of all symptoms and signs. Although there was quantitively decrease in frequency of some signs and symptoms, complete resolution of the disease was not observed generally.

Conclusion

Empiric antireflux treatment according to RSI and RFS is an effective method. Antireflux treatment has a significant improving effect on laryngopharyngeal symptoms and signs. There may be needed longer times of treatment for complete resolution of symptoms and signs.

幽门螺旋杆菌感染对症状性咽喉反流患者唾液胃蛋白酶浓度的影响

目的 探讨幽门螺旋杆菌(HP)感染对症状性咽喉反流(LPR)患者唾液胃蛋白酶浓度的影响。方法 将咽部异物感、反复清嗓等非特异性症状为主诉的229例LPR初诊患者作为研究对象。应用¹⁴C呼气试验将所有LPR患者分为HP阳性组和HP阴性组,并分别给予HP根除治疗(三联疗法)与抑酸治疗。所有患者在初诊及治疗后复诊时均收集唾液样本(HP阳性者复诊时复查¹⁴C呼气试验),并比较治疗前后反流症状指数量表(reflux symptom index, RSI)、反流体征评分量表(reflux finding score, RFS)评分和唾液胃蛋白酶浓度变化。结果 HP阳性的LPR患者其RSI及RFS总分与HP阴性者相比无显著差异(11.00 vs 9.00,P=0.077; 8.50 vs 9.00,P=0.415),但HP阳性者其声嘶(P=0.005)、烦人的咳嗽(P=0.016)等症状评分,声带水肿(P=0.002)体征评分及唾液胃蛋白酶浓度显著高于HP阴性者(94.90μg/mL vs 45.28μg/mL,P<0.001),且治疗后HP阳性的L...     

Ryan指数与反流症状指数量表、反流体征量表在咽喉反流性疾病诊断中的相关性分析

目的 探讨Ryan指数与反流症状指数量表(RSI)、反流体征量表(RFS)在咽喉反流性疾病诊断中的相关性。 方法 回顾性分析以咽喉部不适症状就诊,病程1个月以上的行咽部pH检测的230例患者临床资料。所有患者均同时行电子喉镜检测,并行RSI、RFS评估。 结果 Ryan指数阳性率为15.2%(35/230)。RSI、RFS、RSI或RFS及RSI且RFS阳性率分别为46.5%、28.7%、60.9%、13.9%。Ryan指数阳性组患者RFS评分高于Ryan指数阴性组患者,RSI评分与Ryan指数阴性组患者差异无统计学意义。RFS阳性,RSI或RFS,RSI且RFS阳性组Ryan指数阳性率高于RFS阴性,RSI或RFS,RSI且RFS阴性组。Ryan指数阳性与RSI、RFS、RSI或RFS及RSI且RFS阳性的一致性检验的kappa值分别为-0.06,0.394,0.116和0.172。以pH监测作为金标准时,RSI、RFS、RSI或RFS及RSI且RFS的敏感性分别为37.1%,74.3%,82.9%,28.6%;特异性分别为51.8%,79.5%,43.1%,88.2%;阳性预测值分别为12.1%,39.4%,20.7%,30.3%;阴性预测值分别为82.1%,94.5%,93.3%,87.3%。RSI与直立位及平卧位Ryan指数的相关系数分别为-0.056和-0.083;RFS与直立位及平卧位Ryan指数的相关系数分别为0.425和0.166。 结论 咽部pH检测是直接反映咽喉部反流的客观、无创的检测方法。RFS与Ryan指数有一定的正相关性,但量表与Ryan指数一致性差。尚需进一步研究更准确的、反映咽喉反流的量表及pH诊断指数。     

The influence of laryngopharyngeal reflux in the healing of laryngeal trauma

The aim of this clinical study was to evaluate the effect of laryngopharyngeal reflux (LPR) on the healing process of surgical laryngeal trauma. A total of 112 consecutive patients, who suffered from LPR and were scheduled for operation of Reinke edema or laryngeal polyps/nodules (40 and 72 patients, respectively) during a period of 5 years, were included. Diagnosis of LPR was made on the basis of both history and dual pH probe recording during 24 h in the inferior esophagus and the hypopharynx. The reflux finding score (RFS) and the reflux symptom index (RSI) were used to estimate the clinical severity of LPR. In patients with LPR, proton pump inhibitors (PPI) were initiated in half of them, randomly chosen. Fifty LPR-free subjects operated for Reinke edema or laryngeal polyps during the same time period (19 and 31 patients, respectively) were used as controls. In six patients who had been administered PPI, resolution of the disease was observed and no surgical treatment was undertaken. The remaining patients were operated on under general anesthesia by a single surgeon. All patients had 1-year postoperative follow-up. Epithelization was complete in all vocal cords of both the control group and the group of patients who had been administered PPI. Within the group of patients who had not taken PPI, six patients presented granulation tissue or recurrence of the polyps and in two of them revision surgery was needed. RFS and RSI scores showed significant improvement postoperatively, across all the three groups of patients, with major differences observed in the group treated by PPI. Comparison of the postoperative RFS and RSI scores between the two groups of patients with LPR showed statistically significant differences in both, indicating better treatment outcome in those patients who had received PPI. It may be thus concluded that LPR influences epithelization and recurrence of laryngeal polyps or Reinke edema in vocal cords, after partial or total decortication. Surgical outcome is superior in patients with LPR with preoperative and postoperative anti-reflux treatment.
