Impact of Nissen fundoplication on laryngopharyngeal reflux symptoms

Efficacy and safety of fundoplication in treating gastroesophageal reflux-related chronic cough: A meta-analysis

Gastroesophageal reflux related chronic cough (GERC), is a common type of chronic cough. Drug treatment is the first choice. But some patients are tired of taking medicine everyday and some patients can not benefit from drugs. For these patients, fundoplication may be the most effective method. However, the importance of fundoplication in treating GERC is undervalued, and there is very few meta-analysis looking into the effect and safety of fundoplication in treating GERC. To solve this question, we performed this meta-analysis. The PRISMA strategy was used for this study. Our study was registered with PROSPERO (ID: CRD42021251072). We searched PubMed, Medline, Web of Science, and the Cochrane databases from 1990 to December of 2022. The meta-analysis was performed with Review Manager 5.4 and Stata 14. After selection and exclusion, 15 articles out of 672 were included. The meta-analysis showed that the cure rate of laparoscopic fundoplication in treating GERC was 58% (95%CI: 52%-65%), with I2 = 45%; and the effective rate was 86% (95%CI: 80%-93%), with I2 = 0%. Laparoscopic fundoplication is effective for the most of GERC patients; however, when the goal is to cure GERC completely, a relatively conservative attitude should be taken. In terms of safety, laparoscopic fundoplication is quite reliable offered by skilled surgeons.

The Inclusion of Voice Assessments to Aid Diagnostic and Surgical Decision Making for Patients With Laryngopharyngeal Reflux

OBJECTIVE

Patients with suspected laryngopharyngeal reflux (LPR) present with a variety of symptoms, such as cough, hoarseness, and globus sensation, and often do not have the classic features associated with gastroesophageal reflux disease.

STUDY DESIGN

To achieve greater clarity in the symptom presentation, response to treatment, and the impact on vocal function among patients presenting with signs and symptoms consistent with LPR, we prospectively evaluated initial assessments and outcomes after medication or surgical management.

METHODS

A sample of 109 patients completed self-report measures of reflux symptoms, voice handicap, and underwent diagnostic workup by both laryngologist and foregut surgeon to include laryngoscopy, esophagogastroduodenoscopy, manometry and pH monitoring. Patients were then followed for at least 3 months, and outcomes of therapy were recorded.

RESULTS

The most common indicators on initial workup were reflux symptom inventory score ≥ 13 and at least one abnormality on manometry. Male patients were significantly more likely to demonstrate esophagitis on biopsy, abnormal upper esophageal sphincter mean pressure, and acid (vs nonacid) reflux. Older patients were more likely to have normal esophageal distal contractile integral activity. Significantly higher voice handicap ratings were observed among patients with a positive reflux indicator score in addition to abnormal upper esophageal sphincter mean basal pressure and contractile front velocity. Patients with acid versus nonacid reflux were equally as likely to report non-responsivity to antisecretory medications. Among a subset of patients with 3-month follow-up data (N = 39), reflux scores were significantly lower irrespective of treatment modality (surgical vs pharmacological intervention).

CONCLUSION

Extensive comprehensive workup did not reveal a single predictive indicator for LPR. Voice assessments may be more sensitive to upper esophageal symptomatology or dysfunction compared to reflux assessments, which may be better indicators of inflammation. Our collaborative data confirms the value of assessing vocal quality and impairment, especially in the presence of equivocal reflux indicators, as together these measures may achieve greater sensitivity to reflux issues and may aid in surgical decision making.

Medium-term clinical efficacy of endoscopic antireflux mucosectomy on laryngopharyngeal reflux: a retrospective multicenter cohort study

BACKGROUND AND AIMS

Studies on the effect of antireflux mucosectomy (ARMS) on laryngopharyngeal reflux disease (LPRD) are lacking. We conducted a multicenter retrospective study to explore the clinical efficacy of ARMS on LPRD.

METHODS

We retrospectively analyzed the data of patients diagnosed with LPRD by oropharyngeal 24-hour Dx-pH monitoring who underwent ARMS. The effects of ARMS on LPRD were evaluated by comparing the 36-Item Short-Form Survey (SF-36), reflux symptom index (RSI), and 24-hour Dx-pH monitoring scores before and 1 year after surgery. Patients were divided into groups according to gastroesophageal flap valve (GEFV) grade to explore the effect of GEFV on prognosis.

RESULTS

One hundred eighty-three patients were included in the study. The oropharyngeal pH monitoring results showed that the effective rate of ARMS was 72.1% (132/183). After surgery, the SF-36 score was higher (P = .000), RSI score was lower (P = .000), and the symptoms of constant throat clearing; difficulty swallowing food, liquids, and pills; coughing after eating or after lying down; troublesome or annoying cough; and breathing difficulties or choking episodes were significantly improved (P < .05). Upright reflux was dominant in GEFV grade I to III patients, and the SF-36, RSI, and upright Ryan index scores were significantly improved after surgery (P < .05). In GEFV grade IV patients, regurgitation was dominant in the supine position, and the above evaluation indexes were worse after surgery (P < .05).

CONCLUSIONS

ARMS is effective for LPRD. The GEFV grade can predict the prognosis of surgery. ARMS is effective in GEFV grade I to III patients, but the effect is not exact in GEFV grade IV patients and may even be aggravated.

Best Practices in Treatment of Laryngopharyngeal Reflux Disease: A Multidisciplinary Modified Delphi Study

BACKGROUND

Laryngopharyngeal reflux (LPR) is a common otolaryngologic diagnosis. Treatment of presumed LPR remains challenging, and limited frameworks exist to guide treatment.

METHODS

Using RAND/University of California, Los Angeles (UCLA) Appropriateness Methods, a modified Delphi approach identified consensus statements to guide LPR treatment. Experts independently and blindly scored proposed statements on importance, scientific acceptability, usability, and feasibility in a four-round iterative process. Accepted measures reached scores with ≥ 80% agreement in the 7-9 range (on a 9-point Likert scale) across all four categories.

RESULTS

Fifteen experts rated 36 proposed initial statements. In round one, 10 (27.8%) statements were rated as valid. In round two, 8 statements were modified based on panel suggestions, and experts subsequently rated 5 of these statements as valid. Round three's discussion refined statements not yet accepted, and in round four, additional voting identified 2 additional statements as valid. In total, 17 (47.2%) best practice statements reached consensus, touching on topics as varied as role of empiric treatment, medication use, lifestyle modifications, and indications for laryngoscopy.

CONCLUSION

Using a well-tested methodology, best practice statements in the treatment of LPR were identified. The statements serve to guide physicians on LPR treatment considerations.

Irritant-Induced Chronic Cough Triggers: A Scoping Review and Clinical Checklist

Purpose The primary aim of this review was to identify environmental irritants known to trigger chronic cough through the life span and develop a comprehensive clinically useful irritant checklist. Method A scoping review was conducted using the Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Reviews, checklist, and explanation. English-language, full-text resources were identified through Medline, PsycINFO, SPORTDiscus, Web of Science, and ProQuest Dissertations and Theses Global. Results A total of 1,072 sources were retrieved; of these, 109 were duplicates. Titles of abstracts of 963 articles were screened, with 295 selected for full-text review. Using the exclusion and inclusion criteria listed, 236 articles were considered eligible and 214 different triggers were identified. Triggers were identified from North America, Europe, Africa, Asia, and Australia. Occupational exposures were also delineated. Conclusions A clinically useful checklist of both frequently encountered triggers and idiosyncratic or rare triggers was developed. The clinical checklist provides a unique contribution to streamline and standardize clinical assessment of irritant-induced chronic cough. The international scope of this review extends the usefulness of the clinical checklist to clinicians on most continents.

Surgical Treatment for Laryngopharyngeal Reflux Disease: A Systematic Review

Importance

Laryngopharyngeal reflux (LPR) is a prevalent disease that is usually treated with diet, lifestyle modifications, and proton pump inhibitor therapy. However, nearly 10% to 30% of patients do not achieve adequate acid suppression even with high doses of proton pump inhibitors. For these patients with resistant disease, fundoplication may be recommended but the success rate of fundoplication surgery on laryngopharyngeal symptoms and findings remains uncertain.

Objective

To determine whether fundoplication is associated with control of signs and symptoms in patients with LPR.

Evidence Review

A literature search was conducted on PubMed, Cochrane Library, and Scopus according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline to identify studies published between 1990 and 2018 about the efficacy of fundoplication on clinical outcomes of LPR. Three investigators screened publications for eligibility and exclusion based on predetermined criteria. Study design, patient characteristics, diagnostic method, exclusion criteria, treatment characteristics, follow-up, and quality of the outcome assessment were evaluated.

Findings

Of the 266 studies identified, 34 met the inclusion criteria, accounting for 2190 patients with LPR (1270 women and 920 men; mean [SD] age at the time of surgery, 49.3 [6.3] years). A weighted mean of 83.0% of patients (95% CI, 79.7%-86.3%) experienced improvement and a weighted mean of 67.0% of patients (95% CI, 64.1%-69.9%) experienced a disappearance of symptoms, but there is a high level of methodological heterogeneity among studies according to diagnostic method, exclusion criteria, and outcomes used to assess the efficacy of fundoplication. A pH study without impedance study was used in most studies but with various inclusion criteria. According to results of an a priori assessment, the clinical outcomes used were overall poor, excluding many symptoms and findings associated with LPR.

Conclusion and Relevance

The reported studies of fundoplication in LPR disease have important heterogeneity in method of diagnosis, exclusion criteria, symptoms, and signs assessed as therapeutic outcomes; therefore, this systematic review was nonconclusive regarding whether surgery for LPR disease is associated with effective control of sight and symptoms. Otolaryngologists, gastroenterologists, and surgeons must establish a diagnostic criterion standard, clear indications for surgery, and future clinical outcomes to precisely assess the effectiveness of treatment.

Anti-reflux surgery for controlling respiratory symptoms of gastro-esophageal reflux disease: A systematic review and meta-analysis

Gastro-esophageal reflux disease (GERD) patients have a higher prevalence of airway symptoms, such as chronic cough, wheezing, and hoarseness. The therapeutic management of patients with these symptoms is controversial. Therefore, this study aims to perform a systematic review and meta-analysis evaluating the efficacy of anti-reflux surgery for controlling respiratory symptoms related to GERD. A systematic review and meta-analysis was performed. Extraction of the data concerning proportions of participants who were not free of respiratory symptoms related to GERD (cough, wheezing, hoarseness) or not substantially improved at follow-ups (failure to cure) was performed. Of the 3,424 initially screened articles, 68 studies were included for systematic review and 61 were included for meta-analysis, with a cumulative sample size of 3,869 patients. Of all the included patients, after anti-reflux surgery, the general symptoms improvement was 80% (95% CI 75.2-84%). The numbers needed to harm (NNH) and the numbers needed to treat (NNT) were 15.21 and 1.23, respectively. Of the included patients, 83.4% (95% CI 78.3-87.5%) patients reported improvement in cough symptoms after surgery. For the wheezing symptom, 71.5% (95% CI 62.9-78.8%) reported improvement after surgery. Moreover, surgery presented better results in improving respiratory symptoms than medical therapy (risk difference: -0.46; 95% CI -0.77, -0.16). Physicians should strongly consider surgical anti-reflux procedures for controlling respiratory symptoms in GERD patients after proper patient selection. Anti-reflux surgery has shown high efficacy in improving respiratory symptoms related to GERD, even when compared to medical therapy.

How to select patients for antireflux surgery? The ICARUS guidelines (international consensus regarding preoperative examinations and clinical characteristics assessment to select adult patients for antireflux surgery)

OBJECTIVE

Antireflux surgery can be proposed in patients with GORD, especially when proton pump inhibitor (PPI) use leads to incomplete symptom improvement. However, to date, international consensus guidelines on the clinical criteria and additional technical examinations used in patient selection for antireflux surgery are lacking. We aimed at generating key recommendations in the selection of patients for antireflux surgery.

DESIGN

We included 35 international experts (gastroenterologists, surgeons and physiologists) in a Delphi process and developed 37 statements that were revised by the Consensus Group, to start the Delphi process. Three voting rounds followed where each statement was presented with the evidence summary. The panel indicated the degree of agreement for the statement. When 80% of the Consensus Group agreed (A+/A) with a statement, this was defined as consensus. All votes were mutually anonymous.

RESULTS

Patients with heartburn with a satisfactory response to PPIs, patients with a hiatal hernia (HH), patients with oesophagitis Los Angeles (LA) grade B or higher and patients with Barrett's oesophagus are good candidates for antireflux surgery. An endoscopy prior to antireflux surgery is mandatory and a barium swallow should be performed in patients with suspicion of a HH or short oesophagus. Oesophageal manometry is mandatory to rule out major motility disorders. Finally, oesophageal pH (±impedance) monitoring of PPI is mandatory to select patients for antireflux surgery, if endoscopy is negative for unequivocal reflux oesophagitis.

CONCLUSION

With the ICARUS guidelines, we generated key recommendations for selection of patients for antireflux surgery.

Extraesophageal Symptoms and Diseases Attributed to GERD: Where is the Pendulum Swinging Now?

The purpose of this review is to outline the recent developments in the field of extraesophageal reflux disease and provide clinically relevant recommendations. The recommendations outlined in this review are based on expert opinion and on relevant publications from PubMed and EMbase. The Clinical Practice Updates Committee of the American Gastroenterological Association proposes the following recommendations: Best Practice Advice 1: The role of a gastroenterologist in patients referred for evaluation of suspected extra esophageal symptom is to assess for gastroesophageal etiologies that could contribute to the presenting symptoms. Best Practice Advice 2: Non-GI evaluations by ENT, pulmonary and/or allergy are essential and often should be performed initially in most patients as the cause of the extraesophageal symptom is commonly multifactorial or not esophageal in origin. Best Practice Advice 3: Empiric therapy with aggressive acid suppression for 6-8 weeks with special focus on response of the extraesophageal symptoms can help in assessing association between reflux and extraesophageal symptoms. Best Practice Advice 4: No single testing methodology exists to definitively identify reflux as the etiology for the suspected extra esophageal symptoms. Best Practice Advice 5: Constellation of patient presentation, diagnostic test results and response to therapy should be employed in the determination of reflux as a possible etiology in extra esophageal symptoms. Best Practice Advice 6: Testing may need to be off or on proton pump inhibitor (PPI) therapy depending on patients' presenting demographics and symptoms in assessing the likelihood of abnormal gastroesophageal reflux. A. On therapy testing may be considered in those with high probability of baseline reflux (those with previous esophagitis, Barrett's esophagus or abnormal pH). B. Off therapy testing may be considered in those with low probability of baseline reflux with the goal of identifying moderate to severe reflux at baseline. Best Practice Advice 7: Lack of response to aggressive acid suppressive therapy combined with normal pH testing off therapy or impedance-pH testing on therapy significantly reduces the likelihood that reflux is a contributing etiology in presenting extraesophageal symptoms. Best Practice Advice 8: Surgical fundoplication is discouraged in those with extra esophageal reflux symptoms unresponsive to aggressive PPI therapy. Best Practice Advice 9: Fundoplication should only be considered in those with a mechanical defect (e.g., hiatal hernia), moderate to severe reflux at baseline off PPI therapy who have continued reflux despite PPI therapy and have failed more conservative non-GI treatments.

Surgical Treatment of Extraesophageal Manifestations of Gastroesophageal Reflux Disease

OBJECTIVE

To review the current literature on the role of antireflux surgery (ARS) for the treatment of extraesophageal manifestations of GERD. The extraesophageal manifestations of gastroesophageal reflux disease (GERD) include chronic cough, laryngopharyngeal reflux, and asthma. They are responsible for significant morbidity in affected patients and a high economic burden on healthcare resources. We recently published a larger review on the symptoms, diagnosis, medical, and surgical treatment of the extraesophageal manifestations of GERD. Through our investigation, we found that the role of ARS for respiratory symptoms was unclear. Hence, we resorted through the data of our previous meta-analysis to compile a comprehensive and focused review on the role of ARS for respiratory symptoms.

METHODS

Using the archive of our previous meta-analysis, we selected studies extracted from the MEDLINE, Cochran, PubMed, Google Scholar, and Embase databases pertaining to the surgical treatment of extraesophageal manifestations of reflux (cough laryngopharyngeal reflux, and asthma). We applied a similar reporting methodology as was used in our previous manuscript and then hand searched the bibliographies of included studies yielding a total of 27 articles for review. We graded the level of evidence and classified recommendations by size of treatment effect per the American Heart Association Task Force on Practice Guidelines.

RESULTS

Observational data indicated that syndromes of chronic cough, laryngopharyngeal reflux and asthma might improve after antireflux surgery only in highly selected patients-likely those with non-acid reflux-while those patients with objective markers of asthma severity do not. Because of the varied methods of diagnosis and surgical technique, non-comparative observational data may be unreliable. Additionally, our search found no randomized controlled trials (RCTs) comparing antireflux surgery to medical therapy in the treatment of cough or laryngopharyngeal reflux. One RCT compared medical treatment to antireflux surgery in patients with asthma, but medical treatment included high-dose H₂ blockers instead of PPIs.

CONCLUSIONS

Extraesophageal manifestations of GERD are common, costly, and difficult to treat. ARS might be effective in highly selected patients, especially in those whose extraesophageal manifestations are caused by non-acid reflux. The available data to date are generally of poor quality or outdated. Well-designed randomized controlled trials or large-scale observational cohort studies are urgently needed.

Allergic laryngitis: unraveling the myths

PURPOSE OF REVIEW

This article provides a thorough review of the literature highlighting the articles that have advanced our knowledge about the sensitivity of the larynx to allergens in the air or ones consumed. This area of inquiry requires continued interest and investigation. As the field of clinical laryngology changes, and more information is discovered about the possible causal association between allergy and vocal pathologies, practicing otolaryngologists, allergists, and other medical professionals may discover more comprehensive methods to evaluate and treat their allergic patients, particularly those who present with complaints of dysphonia, dysphagia, laryngopharyngeal reflux (LPR), and/or dyspnea.

RECENT FINDINGS

There continues to be epidemiological studies designed to describe the relationship of allergy to vocal symptoms and signs. Both population and smaller studies have recently attempted to link these two conditions. Unfortunately, the patient with chronic laryngeal complaints is often tagged by default with the diagnosis of LPR and treated with proton pump inhibitors, which are not always beneficial. The endoscopic assessment may not be as reliable to make the diagnosis of LPR as the examination is subjective and the inter-rater reliability is low. It has been demonstrated by direct laryngeal provocation studies that sticky-viscous endo-laryngeal mucous is the only reliable finding consistently associated with allergy potential allergic tissue reactivity.

SUMMARY

The interrelationship of allergic sensitivity and chronic laryngitis in certain individuals is becoming clearer because our knowledge of inquiry has increased and the available routine technology to diagnose these conditions has remarkably improved. Notwithstanding these advancements, much more research is needed on this subject to reduce the frequency of mis-diagnoses and mis-management of allergic patients.

Diagnosis and Treatment of the Extraesophageal Manifestations of Gastroesophageal Reflux Disease

OBJECTIVE

To review the clinical presentation, diagnosis, and treatment options available for management of extraesophageal manifestations of gastroesophageal reflux disease (GERD) and to compare the most recent technological advances to the existing guidelines.

SUMMARY BACKGROUND DATA

Extraesophageal manifestations of GERD include cough, laryngopharyngeal reflux (LPR), and asthma. Recent advances in diagnostic modalities may have outpaced the existing diagnostic and therapeutic clinical guidelines.

METHODS

We searched the MEDLINE, Cochrane, and Embase databases for articles pertaining to the presentation, diagnosis, and treatment of extraesophageal manifestations of reflux, specifically cough due to reflux, LPR, and asthma due to reflux. Search terms applied to 3 thematic topics: diagnosis, medical treatment, and surgical treatment. We had searched the bibliographies of included studies, yielding a total of 271 articles for full review. We graded the level of evidence and classified recommendations by size of treatment effect, according to the guidelines from the American Heart Association Task Force on Practice Guidelines.

RESULTS

One hundred twenty-eight articles met criteria for analysis. Our findings show that the diagnosis of cough, LPR, or asthma due to gastroesophageal reflux is difficult, as no criterion standard test exits. Also, patients often present without heartburn or regurgitation typical of GERD. Combined multichannel intraluminal impedance, the pH (MII-pH) monitoring system, and the symptom association probability (SAP) test might distinguish extraesophageal manifestations of reflux from idiopathic chronic cough, laryngitis due to other causes, and atopic asthma. In addition, extraesophageal manifestations of reflux are most effectively diagnosed with a stepwise approach incorporating empiric treatment and antisecretory therapy, combined MII-pH monitoring, and surgical intervention in few selected cases.

CONCLUSIONS

Recent studies demonstrate the potential diagnostic role of MII-pH monitoring. Surgical intervention provides resolution of extraesophageal symptoms less reliably than typical symptoms when the patient has GERD.

Dual pH with Multichannel Intraluminal Impedance Testing in the Evaluation of Subjective Laryngopharyngeal Reflux Symptoms

Objectives

Minimal data exist to define the use of contemporary dual pH with multichannel intraluminal impedance (MII) probes integrating both pharyngeal acid and impedance sensors to evaluate laryngopharyngeal reflux (LPR) symptoms in a laryngology clinic population. This study was performed to review a series of patients tested with dual pH-MII for suspected LPR symptoms and to analyze pH-MII data findings for this patient cohort.

Study Design

Case series with planned data collection.

Setting

Tertiary laryngology clinic.

Subjects and Methods

Patients with symptoms suggestive of possible LPR (dysphonia, chronic cough, globus sensation, subglottic stenosis,) were evaluated with a dual pH-MII system, as well as previously validated reflux finding score (RFS) and reflux symptom index (RSI) instruments.

Results

A total of 109 patients were evaluated with dual pH-MII studies between 2010 and 2015, with 51 (47%) studies interpreted as “positive” for evidence of significant LPR, 43 (39%) as “negative,” and 15 (14%) as “equivocal.” Dual pH-MII data analysis showed that positive studies had an average of 2.84 pharyngeal acid exposures below pH 4 (vs 0.28 for negative) and 46 episodes of proximal reflux exposure (either acid or nonacid) by impedance detection (vs 30.6 for negative). RSI scores were significantly different between positive and negative studies, while RFS scores were not.

Conclusions

Dual pH-MII analysis is a useful supplementary tool to provide objective evidence of pharyngeal reflux exposure in patients with suspected LPR. RSI scores appear to correlate with objective evidence of acid exposure in the pharynx, while RFS scores do not.

Nissen Fundoplication for Laryngopharyngeal Reflux After Patient Selection Using Dual pH, Full Column Impedance Testing

Objectives:

Prior studies demonstrate inconsistent diagnostic strategies for laryngopharyngeal reflux disease (LPR) patients who are offered laparoscopic Nissen fundoplication (Nissen). Superior symptom resolution outcomes are demonstrated in patients with accompanying typical gastroesophageal reflux (GERD) symptoms. This study aims to evaluate the efficacy of selecting patients with LPR complaints for Nissen using full column, dual pH impedance catheters (multichannel intraluminal impedance catheters [MII]).

Methods:

All patients who underwent Nissen for management of LPR symptoms refractory to at least 3 months of twice daily (BID) proton pump inhibitor (PPI) therapy with reflux symptom index (RSI) of 13 or higher and who had demonstrable reflux on MII were included. Pre- and (minimum) 16 week post-Nissen RSI scores as well as LPR-specific complaints were collected.

Results:

Eleven patients met criteria. Nine subjects (5 female, 4 male) had complete data. All 9 (100%) achieved improvement in RSI. The average pre-Nissen RSI was 31.7, and average post-Nissen RSI was 10 ( P < .001). Six (67%) subjects dropped below an RSI of 13. Seven subjects (78%) had resolution of their primary LPR symptom, and 6 (67%) subjects had resolution of all LPR symptoms.

Conclusions:

Patients with LPR who are selected using dual pH and full column impedance are likely to demonstrate improvement in RSI following Nissen.

Reflux and Voice Disorders: Have We Established Causality?

A trend of attributing abnormal voice changes to reflux has gained momentum among medical professionals over the last few decades. Evidence supporting the connection between reflux and voice and the use of anti-reflux medication in patients with dysphonia is conflicting and deserves careful examination. In the current health care environment, it is important that medical decisions be based on science rather than anecdote and practice patterns. The goal of this review is to investigate the evidence linking reflux and voice changes. Specifically, this association will be examined in the context of the Bradford-Hill criteria to determine what evidence exists for a causal relationship between this exposure (reflux) and outcome (voice change).

Extra-esophageal gastroesophageal reflux disease and asthma: understanding this interplay

Gastroesophageal reflux disease (GERD) is a condition that develops when there is reflux of stomach contents, which typically manifests as heartburn and regurgitation. These esophageal symptoms are well recognized; however, there are extra-esophageal manifestations of GERD, which include asthma, chronic cough, laryngitis and sinusitis. With the rising incidence of asthma, there is increasing interest in identifying how GERD impacts asthma development and therapy. Due to the poor sensitivity of endoscopy and pH monitoring, empiric therapy with proton pump inhibitors (PPIs) is now considered the initial diagnostic step in patients suspected of having GERD-related symptoms. If unresponsive, diagnostic testing with pH monitoring off therapy and/or impedance/pH monitoring on therapy, may be reasonable in order to assess for baseline presence of reflux with the former and exclude continued acid or weakly acid reflux with the latter tests. PPI-unresponsive asthmatics, without overt regurgitation, usually have either no reflux or causes other than GERD. In this group, PPI therapy should be discontinued. In those with GERD as a contributing factor acid suppressive therapy should be continued as well as optimally treating other etiologies requiring concomitant treatment. Surgical fundoplication is rarely needed but in those with a large hiatal hernia, moderate-to-severe reflux by pH monitoring surgery might be helpful in eliminating the need for high-dose acid suppressive therapy.

Prokinetic agents and laryngopharyngeal reflux disease: Prokinetic agents and laryngopharyngeal reflux disease: a systematic review

OBJECTIVES

Our objective was to systematically identify and evaluate prospective studies providing evidence for and against the use of prokinetic agents in the treatment of laryngopharyngeal reflux (LPR) disease.

DATA SOURCES

Our data sources were PubMed, Embase, BIOSIS, and Web of Science databases.

REVIEW METHODS

A systematic literature review was conducted to identify studies prospectively evaluating the effectiveness of prokinetic agents in the treatment of LPR. Data from eligible studies were independently extracted from each study by two authors. The primary outcome of interest was the improvement of LPR symptoms among study participants. Secondary outcomes included resolution of LPR physical signs and the development of side effects from therapy.

RESULTS

Among 724 unique articles identified, four studies met inclusion criteria. These four investigations provided mixed evidence about the effectiveness of prokinetic agents in the treatment of LPR. The studies included in the review were deemed to be at high risk of bias. Three of the four investigations demonstrated a statistically significant difference in patient symptoms that favored the use of prokinetics in the management of LPR. The investigations were mixed in their report of improvement in physical examination findings among patients receiving and those not receiving prokinetic medical therapy. No significant adverse effects were described in any of these trials.

CONCLUSIONS

Prokinetic agents may be a viable treatment option for LPR. The current body of literature is inadequate to make a recommendation for their use in this disease process. Further research should be conducted to assess the use of prokinetic medications in the management of LPR.

Transferable skills in the field of speech language pathology

PURPOSE

To highlight new knowledge and technologies that support the transfer of skills generally acquired by speech language pathologists (SLPs) in academic training programs and clinical practice to involvement in the evaluation and management of individuals with disorders such as paradoxical vocal fold movement (PVFM), chronic cough, manifestations of extra-esophageal reflux (EER), esophageal dysphagia and rumination disorder.

RECENT FINDINGS

A range of studies published in the previous year provide data to support SLP involvement in the management of some disorders, including PVFM, chronic cough, and some manifestations of EER, both as providers and as clinical resources for other health professionals. However, little research is available that describes the role of SLPs in management of esophageal dysphagia or rumination disorder.

SUMMARY

Recent research supports the expanded role of the SLP in the interdisciplinary management of PVFM, chronic cough, manifestations of EER, esophageal dysphagia, and rumination. SLP and other health professionals involved in the care of these patients must find a balance between the practical challenges of treating individuals with increasingly complex medical issues and staying abreast of the latest developments in the diagnosis and treatment of these disorders.
