Abstract
INTRODUCTION Abnormal DeMeester score on pH monitoring is a well-established predictor of favorable outcome after antireflux surgery (ARS). Esophageal pH monitoring also facilitates analysis of the temporal association between symptoms and reflux episodes. This association can be expressed with several symptom-reflux association indices with symptom association probability (SAP) being the most reliable. SAP is often used as an adjunct to DeMeester score during preoperative assessment of patients seeking ARS. However, data on the utility of SAP in predicting ARS outcome is limited. The aim of this study was to determine the utility of SAP as an adjunct to DeMeester score in predicting outcomes after fundoplication. METHODS Records of patients who underwent primary fundoplication from 2015 to 2021 were reviewed. Patients with a preoperative DeMeester score >14.7 on Bravo pH monitoring were included. A SAP >95% was considered SAP-positive. Favorable outcome was defined as freedom from proton pump inhibitors (PPIs) and patient satisfaction at 1 year postoperatively. Outcomes were compared based on the presence and number of SAP-positive symptoms, individual typical and atypical SAP-positive symptoms, and within demographic, clinical, and reflux severity subgroups. RESULTS The final study population consisted of 597 patients (71.4% female) with a median (IQR) age of 59.0 (49-67). At a mean (SD) follow-up of 10.5 (8) months, 82.0% patients achieved favorable outcome (satisfaction and freedom from PPI), freedom from PPI was 91.7%, and satisfaction was 87.4%. SAP was positive in 430 (72.0%) patients, of which 221 (37.0%) had one SAP-positive symptom, 164 (27.5%) had two SAP-positive symptoms, and 45 (7.5%) had all three SAP-positive symptoms. There was no association between having at least one SAP-positive symptom and favorable outcome (p=0.767). There was no difference in favorable outcome between patients with one, two, or all SAP-positive symptoms (0.785). Outcomes were comparable for SAP-positive typical (p=0.873) and atypical symptoms (p=1.000) and all individual symptoms (p>0.05). Outcomes were also comparable within all subgroups (p>0.05). CONCLUSION Symptom association probability with an abnormal DeMeester score did not enhance the prediction of antireflux surgery outcome. These findings suggest that SAP should not be used in surgical decision-making in patients with objective evidence of reflux.

Abstract
The prevalence of gastroesophageal reflux disease (GERD) has been increasing since the 1990 s, with up to 27.8 % of people in North America affected by this disorder. The healthcare burden of patients who primarily have extra-esophageal manifestations of GERD (atypical GERD) is estimated to be 5 times that of patients with primarily heartburn and regurgitation due to lack of a gold standard diagnostic test, poor responsiveness to PPI therapy, and delay in recognition. Empiric twice daily PPI therapy for 1-2 months is currently considered the best diagnostic test, but due to poor responsiveness to PPIs in patients with atypical GERD in multiple randomized controlled trials, newer modes of diagnostic procedures such as oropharyngeal pH monitoring have gained significantly more traction. The utility of oropharyngeal pH monitoring systems such as Restech Dx-pH is currently limited due to lack of consensus on normal and abnormal cutoff values. Recent studies suggest its utility as a prognostic tool and its ability to predict responsiveness to medical and surgical therapy. However, routine use of oropharyngeal pH monitoring is still not widespread due to the lack of well-controlled prospective studies.

Abstract
OBJECTIVES To investigate the laryngopharyngeal reflux (LPR) episodes and pH values in patients with suspected obstructive sleep apnoea (OSA) using the Dx-pH oropharyngeal probe. DESIGN Prospective cohort study. SETTING Tertiary medical centre. PARTICIPANTS Forty patients with complaint of snoring or suspected OSA were prospectively enrolled to receive full nocturnal polysomnography (PSG). The patients were divided into 2 groups: a simple snorers group if the Respiratory Disturbance Index (RDI) was < 5 and an OSA group if the RDI was ≥ 5. MAIN OUTCOME MEASURES The patients simultaneously received Dx-pH oropharyngeal probe monitoring for 12 h from about 6 pm to 6 am of the next day. The number of LPR events was recorded if the nadir of rapid pH drops was below pH 5.0 and 5.5. The difference of LPR events between the two groups and the difference of LPR events between awake and sleep periods in each group were analysed, respectively. RESULTS There were 18 (45%) patients diagnosed as OSA with a mean RDI of 28.7, and 22 patients (55%) diagnosed as simple snorers. Between 2 groups, there were no significant differences in the LPR events and pH values during the awake period, sleep period or overall recording period. Comparison of the LPR events and minimum pH values between the awake period and the sleep period revealed there were no significant differences in either group. CONCLUSION Using the new sensitive Dx-pH oropharyngeal probe with PSG, we found that OSA does not correlate with a higher incidence of LPR episodes.

Pharyngeal pH monitoring better predicts a successful outcome for extraesophageal reflux symptoms after antireflux surgery. Surg Endosc 2013; 27:4113-8.

Abstract
BACKGROUND Gastroesophageal reflux disease can be associated with extraesophageal symptoms (hoarseness, cough, asthma, and globus). However, these symptoms may have a multifactorial etiology. Proximal pH monitoring has been proposed as a means of identifying patients where reflux is the cause of the extraesophageal symptoms. The aim of this study was to determine whether proximal esophageal or pharyngeal pH monitoring better identified patients with extraesophageal symptoms that improved after antireflux surgery. METHODS A retrospective chart review was performed to identify all patients who had esophageal and pharyngeal pH monitoring before an antireflux operation. A composite score was used to define an abnormal result with each test. A successful outcome was defined as improvement or resolution of extraesophageal symptoms. RESULTS There were 20 patients identified. Antireflux surgery led to a successful outcome in 14 patients (70 %). Restech better identified patients with extraesophageal symptoms who had a successful outcome with antireflux surgery (12 of 14 [86 %] based on abnormal Restech versus 5 of 10 [50 %] based on abnormal proximal probe, p = 0.06). Comparing only the 15 patients who had both proximal esophageal and pharyngeal pH monitoring, Restech again better identified those who had a successful outcome with antireflux surgery (9 of 10 [90 %] based on abnormal Restech versus 5 of 10 [50 %] based on abnormal proximal probe, p = 0.05). The positive and negative predictive values for symptomatic improvement after a fundoplication were better for an abnormal Restech score than for an abnormal proximal esophageal score (80 vs. 71 % and 60 vs. 38 %, respectively). In two patients with a successful outcome, Restech was the only positive test. CONCLUSIONS In patients with extraesophageal reflux symptoms, proximal esophageal pH monitoring failed to identify half of the patients who had a successful outcome after antireflux surgery. In contrast, an abnormal Restech pH test was present in 90 % of patients with a successful outcome. Further, a negative Restech study more reliably indicated the absence of reflux-induced extraesophageal symptoms. Our results indicate that Restech pharyngeal pH monitoring should be utilized in the evaluation of patients with extraesophageal symptoms that may be associated with reflux disease.

Abstract
Objectives The pathogenesis of laryngopharyngeal reflux (LPR) remains unclear. It is linked to but distinct from gastroesophageal reflux disease (GERD), which has been shown to be related to disturbed autonomic regulation. The aim of this study is to investigate whether autonomic dysfunction also plays a role in the pathogenesis of LPR. Study Design Case-control study. Setting Tertiary care center. Subjects and Methods Seventeen patients with LPR and 19 healthy controls, aged between 19 and 50 years, were enrolled in the study. The patients were diagnosed with LPR if they had a reflux symptom index (RSI) ≥13 and a reflux finding score (RFS) ≥7. Spectral analysis of heart rate variability (HRV) analysis was used to assess autonomic function. Anxiety and depression levels measured by the Beck Anxiety Inventory (BAI) and Beck Depression Inventory II (BDI-II) were also conducted. Results In HRV analysis, high frequency (HF) represents the parasympathetic activity of the autonomic nervous system, whereas low frequency (LF) represents the total autonomic activity. There were no significant differences in the LF power and HF power between the 2 groups. However, significantly lower HF% ( P = .003) and a higher LF/HF ratio ( P = .012) were found in patients with LPR, who demonstrated poor autonomic modulation and higher sympathetic activity. Anxiety was also frequently observed in the patient group. Conclusion The study suggests that autonomic dysfunction seems to be involved in the pathogenesis of LPR. The potential beneficial effect of autonomic nervous system modulation as a therapeutic modality for LPR merits further investigation.

Abstract
Objective The aim of this study is to evaluate the sensitivity parameters of the percentage of time the pH is <4 and >7, as well as the total number of laryngopharyngeal reflux episodes in 24 hours, in patients with suspected laryngopharyngeal reflux disease. Study Design Retrospective controlled study. Setting University hospital. Subjects and Methods The study was conducted on 46 patients with laryngopharyngeal reflux disease and 58 healthy controls. Patients and controls underwent 24 hours of dual-probe pH monitoring of the distal and cervical esophagus. Patients completed a Reflux Symptom Index questionnaire and underwent esophageal manometry. Data concerning the percentage of time the pH was <4 and >7 and the number of reflux episodes registered at the cervical esophagus were collected and evaluated. Results The percentage of time the pH is <4 and the number of laryngopharyngeal reflux episodes seem to be a reliable diagnostic laryngopharyngeal reflux criterion reaching satisfactory sensitivity (81% and 83%, respectively). Although the pH >7 parameter appeared statistically different between the 2 groups ( P < .001), the sensitivity of the test appeared to be poor (55%). Conclusion Our study demonstrates the importance of the absolute number of laryngopharyngeal reflux episodes in 24 hours in the diagnosis of patients with suspected laryngopharyngeal reflux, proposing it as a new diagnostic criterion.

Abstract
BACKGROUND AND AIM Voice-related complaints are the most common extraesophageal manifestation of gastroesophageal reflux disease (GERD). The aim of this study was to compare objectively measured voice parameters in normal subjects and patients with GERD and to assess the impact of antireflux surgery on these parameters in patients with reflux disease. METHODS Normal subjects and patients with reflux symptoms were asked to read a standardized, phonetically balanced text while the impedance across vocal cords was recorded using electroglottography. Irregularity in the voice frequency (CFx) and amplitude (CAx) as well as irregularity of the closed phase ratio of vocal cords (CQx) were calculated. These 3 voice parameters were compared between the normal subjects and patients with gastroesophageal reflux. In a subgroup of GERD patients who underwent antireflux surgery, electroglottography was repeated 3 months or later after surgery and the voice parameters were compared with preoperative values. RESULTS There were 55 normal subjects and 32 patients with GERD. Compared with normal subjects, GERD patients had a significantly higher irregularity in both voice frequency (P=0.04) and amplitude (P=0.03). The CQx did not differ significantly between the 2 groups (P=0.18). In 16 GERD patients who underwent surgery, a significant improvement in postoperative values was observed for both voice frequency (CFx: 48.4 vs. 30.4, P=0.002) and amplitude (CAx: 25.9 vs. 9.3, P=0.004). CONCLUSIONS There are measurable alterations in voice quality in patients with GERD when compared with normal subjects. Antireflux surgery improves the irregularity in both amplitude and frequency of voice in patients with reflux disease.

Abstract
Objectives. Gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) are very common and controversial diseases. The authors have previously reviewed clinical practice guidelines (CPGs) on reflux disease, and these major consensus statements differ on what constitutes ideal management. The aim is to critically review existing protocols for reflux based on CPG recommendations and to present a refined protocol that may be further used to develop a critical pathway for reflux in ambulatory medical practice. Study Design. Literature review with discussion. Methods. A PubMed search was used to identify current clinical protocols or algorithms for reflux disease, and the principal elements of each were compared. Results. Of the 828 articles identified in the search, 11 met the search criteria. Together with 4 articles previously identified, 15 were analyzed. All protocols discuss the important role of empiric therapy, although with differences in use. Only 5 protocols (33%) were based on systematic review such as CPGs. Eight protocols (53%) used alarm symptoms to prompt a workup. For these patients, upper endoscopy was by far the most common diagnostic method. The use of other modalities varies significantly between protocols. The authors propose a standard protocol based on patient risk factors that employs CPG recommendations and may be used for critical pathway outcomes measures. Conclusion. There are major differences between existing protocols for reflux disease in the literature, reflecting many clinical controversies. Outcomes of different protocols have not been extensively studied. The authors propose a new protocol that is a synthesis of those reviewed and based on risk stratification.
