Laryngopharyngeal reflux disease treated with laparoscopic fundoplication

Laryngopharyngeal Reflux in Patients Who Received or Declined Nissen Fundoplication

OBJECTIVE

To evaluate whether Robotic or Laparoscopic Nissen Fundoplication (LNF) improves voice outcomes and symptoms in patients with Laryngopharyngeal Reflux (LPR) compared to patients who were candidates for surgery but elected to receive treatment with antireflux medical management alone.

STUDY DESIGN

Retrospective chart review.

METHODS

A retrospective chart review was conducted of patients who visited the office of the senior author, received a diagnosis of LPR, and were candidates for LNF. Patients were categorized into two groups: those who received LNF surgery (Nissen-received, n = 50) and those who declined surgery (Nissen-declined, n = 54). Reflux Finding Scores (RFS) collected pre- and post-treatment were compared between groups. 24-hour pH-impedance results also were evaluated pre- and post-treatment.

RESULTS

24-hour pH-impedance testing from patients in the Nissen-received group showed a statistically significant decrease in six recording categories at the proximal sensor and five at the distal sensor, pre- to post-Nissen fundoplication. Proximal sensor categories included: (1) total reflux, (2) supine reflux, (3) acidic reflux, (4) weakly acidic reflux, (5) upright reflux, and (6) total postprandial reflux. Distal sensor categories included: (1) total reflux, (2) weakly acidic reflux, (3) supine reflux, (4) upright reflux, and (5) upright weakly acidic reflux. There were statistically significant differences in the changes from pre- to post-intervention when comparing between the Nissen-received and Nissen-declined groups at three proximal and three distal recordings. The proximal recording categories were (1) total reflux, (2) upright reflux, and (3) upright weakly acidic reflux, and the distal sensor categories were (1) upright reflux, (2) upright weakly acidic reflux, and (3) weakly acidic reflux. The Nissen-received group demonstrated statistically significant improvements in total RFS score, as well as the subcategory score of erythema, from pre- to post-Nissen fundoplication. There were statistically significant differences in the subcategory scores of erythema and diffuse laryngeal edema when comparing the changes from pre- to post-intervention between the Nissen-received and Nissen-declined groups.

CONCLUSION

LNF provides improved LPR control compared with treatment with antireflux medication alone.

Resource utilization and variation among practitioners for evaluating voice hoarseness secondary to suspected reflux disease: A retrospective chart review

The purpose of this study was to assess the variation in resource utilization for the diagnosis and treatment of dysphonia or hoarseness in patients with suspected laryngopharyngeal reflux (LPRD) and/or gastroesophageal reflux (GERD). Secondary data was collected from a single-institution database of charts from patients evaluated between October 1, 2011 and March 31, 2020. This study was conducted as a retrospective chart review. Key outcome variables included demographic data, initial specialty visit, date of first symptom evaluation to final follow-up visit, additional procedural evaluation, and final diagnosis as attributed by the diagnosing physician. Inclusion criteria included patients ≥18 older referred to providers for suspected LPRD/GERD with a primary complaint of voice changes or hoarseness and appeared for follow-up. A total of 134 subjects were included for analysis. Data analysis included descriptive and univariate analysis, chi-square test of independence, independent means t test, and 1-way analysis of variance. Most patients (88) received some form of procedural evaluation in addition to clinical evaluation. The most frequent was videostroboscopy (59). Patients who first visited a gastroenterologist were more likely to undergo esophageal pH-monitoring (n = 14, P < .001) and manometry (n = 10, P < .001). Patients referred to speech-language pathology were very likely to undergo videostroboscopic evaluation (n = 7, P < .001). The prevailing final diagnosis as attributed by the diagnosing physician was confirmed to be of non-reflux etiology (49) or due to GERD alone (34). LPRD only was the least frequent diagnosis (10). Our results demonstrate that there is significant variation in the number and type of diagnostic tests based on the type of practitioner initially seen by the patient. Additionally, of patients thought to have voice change or hoarseness because of LPRD and/or GERD, more than a third had a non-reflux cause of their symptoms. Further research should identify beneficial patterns in resource utilization and further diagnostic utility of diagnostic procedures for more accurate diagnosis.

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.

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.

Voice Disorders and Voice Knowledge in Choir Singers

OBJECTIVES

Singers have reported higher prevalence of vocally harmful behaviors, vocal symptoms, and voice disorders than nonsingers have. The purpose of this study was to investigate the prevalence of voice disorders among choir singers and to discover the risk factors associated with voice disorders. Another purpose was to explore the choir singers' knowledge about the anatomy and physiology of the voice, and voice ergonomics.

METHODS

Three hundred and fifteen adult choir singers, 65% women, and 35% men, completed a web-questionnaire. The questionnaire included demographic questions and questions about vocal symptoms, risk factors for voice disorders, and voice knowledge.

RESULTS

Twenty one percent of the participants experienced two or more frequently occurring vocal symptoms, which was defined as having a functional voice disorder. Choir singers with a vocally demanding profession were almost twice as likely to report several frequently occurring vocal symptoms. Health-related risk factors, such as inhalant allergy and asthma, had a significant relation with the number of vocal symptoms. The overall voice knowledge among the choir singers seemed limited.

CONCLUSIONS

The prevalence of voice disorders among choir singers seems to be similar to the prevalence rate among professional voice users. Choir singers with a vocally demanding profession are at a higher risk of developing a functional voice disorder. The results of this study raise the importance of educating choir singers about the voice, in order to prevent development of voice disorders.

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).

Optimal treatment of laryngopharyngeal reflux disease

Laryngopharyngeal reflux is defined as the reflux of gastric content into larynx and pharynx. A large number of data suggest the growing prevalence of laryngopharyngeal symptoms in patients with gastroesophageal reflux disease. However, laryngopharyngeal reflux is a multifactorial syndrome and gastroesophageal reflux disease is not the only cause involved in its pathogenesis. Current critical issues in diagnosing laryngopharyngeal reflux are many nonspecific laryngeal symptoms and signs, and poor sensitivity and specificity of all currently available diagnostic tests. Although it is a pragmatic clinical strategy to start with empiric trials of proton pump inhibitors, many patients with suspected laryngopharyngeal reflux have persistent symptoms despite maximal acid suppression therapy. Overall, there are scant conflicting results to assess the effect of reflux treatments (including dietary and lifestyle modification, medical treatment, antireflux surgery) on laryngopharyngeal reflux. The present review is aimed at critically discussing the current treatment options in patients with laryngopharyngeal reflux, and provides a perspective on the development of new therapies.

Pharyngeal pH monitoring better predicts a successful outcome for extraesophageal reflux symptoms after antireflux surgery

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.

Globus pharyngeus: a review of its etiology, diagnosis and treatment

Globus is a persistent or intermittent non-painful sensation of a lump or foreign body in the throat. It is a commonly encountered clinical condition that is usually long-lasting, difficult to treat, and has a tendency to recur. Furthermore, due to the uncertain etiology of globus, it remains difficult to establish standard investigation and treatment strategies for affected patients. As a first step for managing globus, careful history taking and nasolaryngoscopy are essential. Given the benign nature of the condition and the recent notion that gastroesophageal reflux disease is a major cause of globus, empirical therapy with a high dose of proton pump inhibitors is reasonable for patients with typical globus. If patients are nonresponsive to this therapy, definitive assessments such as endoscopy, multichannel intraluminal impedance/pH monitoring, and manometry should be considered. Speech and language therapy, anti-depressants, and cognitive-behavioral therapy can be helpful in patients whose symptoms persist despite negative investigations.

Impact of laparoscopic fundoplication for the treatment of laryngopharyngeal reflux: review of the literature

Laryngopharyngeal reflux (LPR) is part of the so-called extraesophageal manifestations of gastroesophageal reflux disease (GERD). It is presented by unspecific symptoms and signs and is believed to be caused by the reflux of gastric content to the proximal esophagus and larynx. However, evidence considering the role of the antireflux surgery for LPR has failed to demonstrate results comparable to those for GERD. The aim of this paper is to review the current literature regarding the impact of laparoscopic fundoplication for the treatment of LPR.

Long-term outcomes after transoral incisionless fundoplication in patients with GERD and LPR symptoms

Background

A retrospective study evaluated safety, symptom resolution, patient satisfaction, and medication use 1–2 years after transoral incisionless fundoplication (TIF) in patients with gastroesophageal reflux disease (GERD) and/or laryngopharyngeal reflux (LPR) symptoms.

Methods

Thirty-four patients with a confirmed diagnosis of GERD symptoms that were inadequately controlled by antisecretory medications, and who where either dissatisfied with their current therapy or not willing to continue taking medication, underwent TIF using EsophyX at our community-based hospital. Follow-up assessments were completed in 28 patients.

Results

Median age of the study group was 57 (range = 23–77) years, BMI was 25.7 (18.3–36.4) kg/m², and 50% were female. All patients had documented chronic GERD for a median 5 (1–20) years and refractory symptoms to proton pump inhibitors (PPIs). Hiatal hernia was present in 75% (21/28) of patients, and 21% (6/28) had erosive esophagitis (LA grade A or B). TIF was performed following a standardized TIF-2 protocol and resulted in reducing hiatal hernia and restoring the natural anatomy of the gastroesophageal (GE) junction (Hill grade I). There were no postoperative complications. At a median 14-months follow-up, 82% (23/28) of patients were off daily PPIs (64% completely off PPIs), and 68% (19/28) were satisfied with their current health condition compared to 4% before TIF. Median GERD Health-Related Quality of Life scores were significantly reduced to 4 (0–25) from 26 (0–45) before TIF (P < 0.001). Heartburn was eliminated in 65% (17/26) and improved by >50% in 86% (24/28) of patients. Regurgitation was eliminated in 80% (16/20) of patients. Atypical LPR symptoms such as hoarseness, coughing, and throat clearing were eliminated in 63% (17/27) of patients as measured by Reflux Symptom Index scores.

Conclusion

Our results in 28 patients confirm the safety and effectiveness of TIF, documenting symptomatic improvement of GERD and LPR symptoms and clinically significant discontinuation of daily PPIs in 82% of patients.

Clinical and pH-metric outcomes of transoral esophagogastric fundoplication for the treatment of gastroesophageal reflux disease

BACKGROUND

Transoral treatment of gastroesophageal reflux disease (GERD) using the EsophyX device enables creation of an esophagogastric fundoplication with potential for better control of reflux than gastrogastric techniques. Efficacy and safety of a rotational/longitudinal esophagogastric transoral incisionless fundoplication (TIF) was evaluated retrospectively using subjective and objective outcomes.

METHODS

Thirty-seven consecutive patients on antisecretory medication and with proven gastroesophageal reflux and limited hiatal hernia underwent TIF for persistent GERD symptoms. Five patients were reoperations for failed laparoscopic fundoplication.

RESULTS

Of the 37 treated patients, 57% were female. The median age was 58 (range=20-81) years and BMI was 25.5 (range=15.9-36.1) kg/m2. Sixty-eight percent indicated GERD-associated cough, asthma, or aspiration as a primary complaint and 32% complained of heartburn or regurgitation. The TIF procedures created tight wraps of 230°-330° extending 3-4 cm above the Z-line. Two complications occurred: one mediastinal abscess treated laparoscopically and one postoperative bleeding requiring transfusion. At 6 (range=3-14) months median follow-up TIF resulted in a significant improvement of both atypical and typical symptoms in 64% and 70-80% of patients, respectively, as indicated by the corresponding GERD health-related quality of life (HRQL) and reflux symptom index (RSI) score reduction by 50% or more compared to baseline on proton pump inhibitors (PPIs). No patient reported problems with dysphagia, bloating, or excess flatulence, and 82% were not taking any PPIs. Reflux characteristics were significantly improved and normalized in 61, 89, and 56% of patients in terms of acid exposure, number of refluxates, and DeMeester scores, respectively. TIF was effective in treating GERD in 75% of patients among whom 54% were in a complete "remission" and 21% were "improved." The remaining 25% were considered failures, and five (13.5%) patients underwent revision.

CONCLUSION

Rotational/longitudinal esophagogastric fundoplication using the EsophyX device significantly improved symptomatic and objective outcomes in over 70% of patients at median 6-month follow-up. Post-fundoplication side effects were not reported after TIF.

Laryngopharyngeal reflux: current concepts and questions

PURPOSE OF REVIEW

Laryngopharyngeal reflux is a widely recognized disorder. Yet, decades after its initial description, debate persists regarding pathophysiology, diagnosis, and treatment. This review addresses current literature on laryngopharyngeal reflux and identifies areas of controversy and future opportunities for research.

RECENT FINDINGS

Despite numerous research efforts, the diagnosis and treatment of laryngopharyngeal reflux remain elusive and unproven. Acid-induced changes in laryngopharyngeal mucosa have been confirmed by histologic evidence. However, the implications of this for laryngeal symptoms and signs are unclear. Diagnosis remains controversial, confounded by lack of standardization and accepted, evidence-based norms. Whereas treatment is generally believed by clinicians to be effective in alleviating symptoms and signs attributed to laryngopharyngeal reflux, incontrovertible data confirming efficacy are scarce. Confounding the issues further, there are numerous studies that purport to show that various widely used treatments are not effective, although the scientific merit of virtually all of these studies has been challenged.

SUMMARY

Laryngopharyngeal reflux remains a controversial diagnosis. Treatment with proton pump inhibitors persists despite weak evidence supporting or refuting their utility, and well designed studies are needed to understand diagnosis, treatment, pathyophysiology, and long-term health consequences of laryngopharyngeal reflux and its treatment.

The diagnosis and management of globus: a perspective from Japan

PURPOSE OF REVIEW

The etiology of globus is multifactorial and its management is controversial. Recent findings in the etiology and diagnosis of globus are discussed, and a subjective opinion on its management is presented.

RECENT FINDINGS

Although there is considerable debate concerning the role of gastroesophageal reflux disease (GERD) in patients with globus, the globus symptom score has been shown to be significantly higher in patients with GERD than in those without GERD. This definite association between GERD and globus leads to the practical division of patients with globus into two groups: the GERD/laryngopharyngeal reflux (LPR)-induced and non-GERD/LPR groups. When the presence of GERD or LPR or both is established in patients with globus, management of this condition should be considered. Owing to limitations in the technology for the detection of GERD/LPR, precise discrimination between the two groups is still difficult. For practical purposes, empirical approaches for targeting GERD in patients with globus appear to be justified. A 24 h pH-metry/multichannel intraluminal impedance test may increase the detection of reflux events in patients with globus.

SUMMARY

A practical approach for dividing patients with globus into GERD/LPR-induced and non-GERD/LPR groups is introduced.
