Background: Many patients diagnosed with gastro-oesophageal reflux disease (GERD) have persistent symptoms despite proton pump inhibitor (PPI) therapy.

Aims: The aim of this consensus is to provide evidence-based statements to guide clinicians caring for patients with refractory reflux-like symptoms (rRLS) or refractory GERD.

Methods: This consensus was developed by the International Working Group for the Classification of Oesophagitis.

Article Synopsis
  • * A group of 48 international experts used a modified Delphi process to review and reach a consensus on 48 statements regarding LPR, achieving agreement on 38 of them (79.2%) after three voting rounds.
  • * The consensus defines LPR as a disease caused by reflux of stomach contents affecting the upper aerodigestive tract, and highlights specific symptoms and diagnostic tools to aid clinicians in recognizing and diagnosing the condition.

The Lyon Consensus provides conclusive criteria for and against the diagnosis of gastro-oesophageal reflux disease (GERD), and adjunctive metrics that consolidate or refute GERD diagnosis when primary criteria are borderline or inconclusive. An international core and working group was assembled to evaluate research since publication of the original Lyon Consensus, and to vote on statements collaboratively developed to update criteria. The Lyon Consensus 2.

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.

Introduction: This is the first randomized controlled diet intervention trial to investigate both the amount and type of carbohydrate on symptomatic gastroesophageal reflux disease (GERD).

Methods: Ninety-eight veterans with symptomatic GERD were randomly assigned to high total/high simple, high total/low simple, low total/high simple, or low total/low simple carbohydrate diet for 9 weeks. The primary outcomes were esophageal acid exposure time (AET) and total number of reflux episodes derived from 24-hour ambulatory pH monitoring.

Introduction: Ambulatory reflux monitoring performed off proton pump inhibitor (PPI) is the gold standard diagnostic test for nonerosive gastroesophageal reflux disease (GERD). However, the diagnostic metrics and optimal duration of monitoring are not well defined. This study evaluated the performance of multiple metrics across distinct durations of wireless reflux monitoring off PPI against the ability to discontinue PPI therapy in patients with suboptimal PPI response.

Background: Optimal ambulatory reflux monitoring methodology in symptomatic reflux patients continues to be debated.

Aims: To utilise published literature and expert opinion to develop recommendation statements addressing use of ambulatory reflux monitoring in clinical practice METHODS: The RAND Appropriateness Method (RAM) was utilised among 17 experts with discussion, revision and two rounds of ranking of recommendation statements. Ambulatory reflux monitoring protocol, methodology and thresholds ranked as appropriate by ≥80% of panellists met the criteria for appropriateness.

Objective: Management of erosive oesophagitis (EE) remains suboptimal, with many patients experiencing incomplete healing, ongoing symptoms, and relapse despite proton pump inhibitor (PPI) treatment. The Study of Acid-Related Disorders investigated patient burden of individuals with EE in a real-world setting.

Design: US gastroenterologists (GIs) or family physicians (FPs)/general practitioners (GPs) treating patients with EE completed a physician survey and enrolled up to four patients with EE for a patient survey, with prespecified data extracted from medical records.

Background: Rising prevalence of gastroesophageal reflux disease (GERD) in US Veterans is concurrent with increasing excess body weight.

Objective: The objective of this cross-sectional study is to examine relationships between dietary macronutrients, gastrointestinal hormones, and GERD status.

Methods: Ninety-eight veterans with overweight/obesity and empiric proton pump inhibitor (PPI) treatment were enrolled from the Tennessee Valley Healthcare System.

Article Synopsis
  • The study evaluated the effects of chronic opioid use on esophageal motility disorders using a large patient cohort, focusing on clinical characteristics and long-term symptoms.
  • Opioid users showed a higher prevalence of dysphagia and were more likely to be diagnosed with distal esophageal spasm (DES) or hypercontractile esophagus (HE) compared to non-users.
  • Results indicated that opioid users experienced a greater long-term symptom burden, as reflected in their PROMIS-GI swallowing domain scores, suggesting significant impacts of opioid exposure on swallowing ability.

Background: Refractory reflux-like symptoms have a substantial impact on patients and healthcare providers. The aim of the survey was to qualitatively assess the needs and attitudes of practicing clinicians around the management of refractory reflux symptoms and refractory gastroesophageal reflux disease (rGERD).

Methods: An International Working Group for the Classification of Oesophagitis (IWGCO) steering committee invited clinicians to complete an online survey including 17 questions.

Dysphagia is a common symptom with significant impact on quality of life. Our diagnostic armamentarium was primarily limited to endoscopy and barium esophagram until the advent of manometric techniques in the 1970s, which provided the first reliable tool for assessment of esophageal motor function. Since that time, significant advances have been made over the last 3 decades in our understanding of various esophageal motility disorders due to improvement in diagnostics with high-resolution esophageal manometry.

Background And Aims: eradication rates have declined as antibiotic resistance rates have increased. In addition, adherence to treatment guidelines is suboptimal. It is therefore important that contemporary, real-world evidence of diagnostic and treatment patterns is explored and compared with evidence-based guidelines.

Objectives: To review the normative data for acid, weakly acid, and nonacid proximal esophageal (PRE) and hypopharyngeal reflux (HRE) events in diagnosing laryngopharyngeal reflux (LPR) using ambulatory reflux monitoring.

Data Sources: PubMed, Cochrane Library, and Scopus.

Review Methods: A literature search was conducted about the normative data for PRE and HRE on multichannel intraluminal impedance-pH monitoring (MII-pH), hypopharyngeal-esophageal MII-pH (HEMII-pH), or oropharyngeal pH monitoring using PICOTS (population, intervention, comparison, outcome, timing, and setting) and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statements.

Gastroesophageal reflux disease (GERD) is a common disorder that is treated with lifestyle modification, weight loss, and medications, such as proton pump inhibitors (PPIs). An empiric course of PPI therapy is an effective and cost-effective strategy for the management of GERD. However, in some patients, PPI therapy and lifestyle changes are inadequate to control symptoms.

Background: The management of achalasia has improved due to diagnostic and therapeutic innovations. However, variability in care delivery remains and no established measures defining quality of care for this population exist. We aimed to use formal methodology to establish quality indicators for achalasia patients.

Article Synopsis
  • The Chicago Classification v4.0 (CCv4.0) is an updated system for categorizing esophageal motility disorders based on high-resolution manometry (HRM) metrics.
  • Developed by 52 international experts over two years, CCv4.0 employs a more comprehensive HRM protocol that includes different positions during testing and new diagnostic criteria.
  • Key improvements aim to reduce ambiguity in diagnoses by distinguishing between conclusive and inconclusive motility disorders based on symptoms and specific tests, ultimately providing clearer standards for assessing esophageal function.
