Radiofrequency ablation in patients with large cervical heterotopic gastric mucosa and globus sensation: Closing the treatment gap

A multidisciplinary approach to identifying and managing heterotopic gastric inlet patches

INTRODUCTION

Gastric inlet patches are often incidental, but can also be a treatable cause of laryngo-esophageal symptoms.

METHODS

We retrospectively reviewed all patients whose gastric inlet patches were diagnosed following assessment for laryngopharyngeal and swallowing symptoms. Improvement following Argon Plasma Coagulation (APC) was assessed using Minimum Clinically-Important Difference methodology combining voice, throat, and swallowing domains. Correlations between APC response and measures of reflux and mucosal barrier integrity, measured during 24-h pH-impedance manometry, were obtained. Proximal and Distal Mean Nocturnal Baseline Impedance (MNBI) values were separately calculated and the novel variable of Mucosal Impedance Gradient was derived as [((Distal MNBI-Proximal MNBI)/((Distal MNBI + Proximal MMBI)/2)) x 100].

KEY RESULTS

Inlet patches were detected in 57 of 651 patients who had Transnasal Panendoscopy (8.7 ± 2.2%). There were 34 males. Mean age was 58 years. Mean duration of symptoms was 2 years. The commonest symptoms were hoarseness (n = 33), throat symptoms (n = 24), and dysphagia (n = 21), respectively. APC was used to ablate patches in 34 patients. Treatment response was 71% at a mean followup of 5.5 months. MIG > - 25% predicted response to APC, with area under the receiver operating characteristic curve of 0.875 (Sensitivity = 81%; Specificity = 100%; p < 0.0001).

CONCLUSIONS

Gastric inlet patches are common and under-recognized. They can cause protracted pharyngo-esophageal symptoms. Patch ablation is an effective treatment for carefully selected patients. Optimal patient selection requires multidisciplinary teamwork. Mucosal Impedance Gradient could further refine patient selection.

Ablation of cervical inlet patch for the treatment of globus sensation: A case report

We present a case of a medically resistant cervical inlet patch causing persistent globus and symptoms of laryngo-pharyngeal reflux, successfully treated with CO2 laser ablation.

The assessment and management of globus pharyngeus

Globus is the sensation of a foreign body in the throat. Investigation and management of patients with globus is widely variable. Most investigations yield negative results yet incur varying patient morbidity and healthcare costs, while malignancy is vanishingly rare in the absence of red flag symptoms and ear, nose and throat examination findings. History taking is key and can help to identify possible causative pathology, directing further investigations and management if necessary. Treatment of globus mainly centres on patient reassurance and counselling, and may include reflux management, neuromodulation, or speech therapy in selected cases, and treatment of any identified cause.

The Relationship Between Gastroesophageal Reflux Disease and Laryngopharyngeal Reflux Based on pH Monitoring

OBJECTIVES

Many studies on the relationship between gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) were based on symptoms, but there are few research on it using reflux monitoring. This study was designed to investigate the relationship between GERD and LPR based on pH monitoring.

METHODS

All patients were scheduled for esophageal manometry and pH monitoring sequentially. They were stratified into 4 groups as no reflux disease, isolated GERD, isolated LPR (iLPR), and GERD combined with LPR (GERD&LPR) according to pH monitoring.

RESULTS

The incidence of LPR in GERD was 46.3%, while the probability of combining GERD in LPR was 52.7%. The reflux profile in the laryngopharynx showed a significant difference in the total reflux time (17.82 ± 18.4 vs 9.62 ± 9.58, P = .023) and the percentage of total reflux time (1.31% ± 1.37% vs 0.71% ± .0.73%, P = .023) between the GERD&LPR and iLPR groups.

CONCLUSION

Laryngopharyngeal reflux can be combined with GERD or it can exist as an independent diagnosis. In patients with GERD&LPR, the total reflux time and the percentage of reflux time in the laryngopharynx are higher than those in the iLPR group. Reflux episodes in the laryngopharynx of patients with GERD&LPR may be derived from GERD.

ESNM/ANMS Review. Diagnosis and management of globus sensation: A clinical challenge

Globus is a non-painful sensation of a tightness or a lump/foreign body in the throat that is not associated with dysphagia and may actually improve during meals. While several otorhinolaryngologic, thyroid, and esophageal disorders have been linked to globus, cause-and-effect relationships are difficult to establish. Consequently, though part of the evaluation, objective otorhinolaryngologic and esophageal testing is often negative. The presence of alarm symptoms, particularly pain, weight loss, dysphagia, or odynophagia is indications for objective testing. A diagnosis of idiopathic globus requires exclusion of pharyngeal, laryngeal, and esophageal disorders with laryngoscopy, endoscopy, high-resolution manometry, barium radiography, and/or ambulatory reflux monitoring. A trial of acid-suppressive therapy may be reasonable in the absence of alarm symptoms, especially if concurrent reflux symptoms are identified. Ablation of heterotopic gastric mucosa in the proximal esophagus has been reported to improve globus symptoms. Beyond these specific approaches, further management of idiopathic globus consists of reassurance, neuromodulators, and complementary approaches. Globus has a benign course with no long-term consequences, and the overall prognosis is good as the magnitude of symptoms may decline over time.

Gastric inlet patches: symptomatic or silent?

PURPOSE OF REVIEW

The purpose of this review is to assess recent literature on the clinical relevance of the gastric inlet patch with particular focus on endoscopic diagnosis and treatment, the relationship of the inlet patch to laryngopharyngeal reflux disease and the association of proximal esophageal adenocarcinoma with inlet patch.

RECENT FINDINGS

Recent studies suggest endoscopic diagnosis of inlet patch increases with endoscopist awareness (up to 10-fold) and when using enhanced imaging techniques such as narrow band imaging (up to three-fold). The literature remains mixed on the association of inlet patch with laryngopharyngeal symptoms or globus sensation. Studies of endoscopic ablation, using argon plasma coagulation or radiofrequency ablation have shown improved laryngopharyngeal reflux symptom scores posttreatment. Proximal esophageal adenocarcinomas are rare but often associated with inlet patch when they occur. Case studies have described endoscopic resection of malignant lesions related to inlet patch, using endoscopic mucosal resection or submucosal dissection.

SUMMARY

Prospective, multicenter studies of symptom association with inlet patch using validated symptom questionnaires and blinded sham-controlled treatments are needed to further clarify the role of such treatments, which to date are limited to a small numbers of centers with a special interest.

The management of suspected or confirmed laryngopharyngeal reflux patients with recalcitrant symptoms: A contemporary review

OBJECTIVE

To summarise current knowledge about the prevalence, aetiology and management of recalcitrant laryngopharyngeal reflux (LPR) patients-those who do not respond to anti-reflux medical treatment.

METHODS

A literature search was conducted following the PRISMA guidelines to identify studies that reported success of anti-reflux medical treatment with emphasis on studies that attempted to be rigorous in defining a population of LPR patients and which subsequently explored the characteristics of non-responder patients (ie aetiology of resistance; differential diagnoses; management and treatment). Three investigators screened publications for eligibility from PubMED, Cochrane Library and Scopus and excluded studies based on predetermined criteria. Design, diagnostic method, exclusion criteria, treatment characteristics, follow-up and quality of outcome assessment were evaluated.

RESULTS

Of the 139 articles screened, 45 met the inclusion criteria. The definition of non-responder patients varied substantially from one study to another and often did not include laryngopharyngeal signs. The reported success rate of conventional therapeutic trials ranged from 17% to 87% and depended on diagnostic criteria, treatment scheme, definition of treatment failure and treatment outcomes that varied substantially between studies. The management of non-responders differed between studies with a few differential diagnoses reported. No study considered the profile of reflux (acidic, weakly acid, non-acid or mixed) or addressed personalised treatment with the addition of alginate or magaldrate, low acid diet, or other interventions that have emerging evidence of efficacy.

CONCLUSION

To date, there is no standardised management of LPR patients who do not respond to traditional treatment approached. A diagnostic and therapeutic algorithm is proposed to improve the management of these patients. Future studies will be necessary to confirm the efficacy of this algorithm through large cohort studies of non-responder LPR patients.

Issues and controversies in esophageal inlet patch

The proximal esophagus is rarely examined, and its inspection is often inadequate. Optical chromoendoscopy techniques such as narrow band imaging improve the detection rate of inlet patches in the proximal esophagus, a region in which their prevalence is likely underestimated. Various studies have reported correlations between these esophageal marks with different issues such as Barrett's esophagus, but these findings remain controversial. Conflicting reports complicate the process of interpreting the clinical features of esophageal inlet patches and underestimate their importance. Unfortunately, the limited clinical data and statistical analyses make reaching any conclusions difficult. It is hypothesized that inlet patches are correlated with various esophageal and extraesophageal symptoms, diagnoses and the personalized therapeutic management of patients with inlet patches as well as the differential diagnosis for premalignant lesions or early cancers. Due to its potential underdiagnosis, there are no consensus guidelines for the management and follow up of inlet patches. This review focuses on questions that were raised from published literature on esophageal inlet patches in adults.

Malformations, choristomas, and hamartomas of the gastrointestinal tract and pancreas

Congenital and hamartomatous lesions of the gastrointestinal tract cause diagnostic challenges for surgical pathologists. Many of these are merely histologic curiosities, whereas others have substantial clinical implications because they herald cancer syndromes or associated anomalies. Although a comprehensive discussion of all developmental abnormalities that can occur in the gastrointestinal tract is beyond the scope of a single manuscript, some entities are more likely to be encountered by surgical pathologists, have important clinical consequences, or pose diagnostic difficulties. The purpose of this review is to discuss the more common malformations and choristomas, as well as hamartomatous lesions that may be clinically important due to their risk for cancer development, frequent associations with heritable cancer syndromes and other anomalies, or potential to simulate other entities.

Globus: Current Concepts and Dilemmas

Globus is an area of interest for many medical specialists including otorhinolaryngologists, gastroenterologist, allergists, and psychiatrists. It may be caused by an organic disease, but it is not uncommon that an underlying etiology remains unidentified even after a full workup has been performed. Patients who suffer from globus usually visit several physicians from different specialties without finding a solution for their symptoms. Identifying the underlying cause of globus is not always a simple task; therefore, structural or functional abnormalities of the thyroid, larynx, pharynx, and esophagus should be investigated. Gastroesophageal reflux disease is commonly considered to be the underlying cause after being identified in an otorhinolarygeal (ear, nose, and throat) evaluation, which is usually the first diagnostic step. In the last few years, an inlet patch in the proximal esophagus has been shown to be associated with globus, and its elimination has resulted in symptom resolution in some patients. Finally, globus can be associated with psychiatric disorders as well as oropharyngeal hypersensitivity that could be either chemical or mechanical. Treatment is directed toward an identified organic cause; in those with a functional disorder, the mainstay of therapy includes neuromodulators and psychiatric/psychological interventions.

How to use Rome IV criteria in the evaluation of esophageal disorders

PURPOSE OF REVIEW

In 2016, the Rome IV process and criteria were published. They provide a system to standardize patient diagnostic requirements for clinical studies and pharmaceutical trials on functional gastrointestinal disorders (FGIDs), which are now called disorders of gut-brain interaction (DGBI). Although the Rome criteria have limitations in clinical practice, an understanding of the criteria can help clinicians to manage symptoms in patients with DGBI, and with organic diseases as well.

RECENT FINDINGS

In this report, the Rome IV criteria for esophageal DGBI, the updated algorithms for esophageal symptoms, and the multidimensional clinical profile (MDCP) are reviewed.

SUMMARY

The esophageal DGBI comprise functional esophageal chest pain, functional heartburn, globus, functional dysphagia, and the newly introduced reflux hypersensitivity. They are characterized by the presence of chronic symptoms attributed to the esophagus without evidence of esophageal structural, inflammatory, or motility abnormalities. Also, Rome IV suggests for the first time the possibility that functional heartburn or reflux hypersensitivity might overlap with gastroesophageal reflux disease. Accordingly, testing with endoscopy and biopsies, esophageal pH ± impedance monitoring and high-resolution esophageal manometry are necessary to establish esophageal DGBI diagnoses. Algorithms aid in this diagnostic process, and the MDCP that captures the full dimension of each patient's presentation is helpful in planning personalized treatment regimens.
