Refractory reflux disease

Gastroesophageal reflux disease (GERD) is common, with increasing worldwide disease prevalence and high economic burden. A significant number of patients will remain symptomatic following an empiric proton pump inhibitor (PPI) trial. Persistent symptoms despite PPI therapy are often mislabeled as refractory GERD. For patients with no prior GERD evidence (unproven GERD), testing is performed off antisecretory therapy to identify objective evidence of pathologic reflux using criteria outlined by the Lyon consensus...

OBJECTIVES: Reflux hypersensitivity (RH) is a form of refractory gastroesophageal reflux disease in which duodenogastroesophageal reflux (DGER) plays a role. This study aimed to determine the usefulness of an endoscopy system equipped with image-enhanced technology for evaluating DGER and RH. METHOD: The image enhancement mode for detecting bilirubin and calculated values were defined as the Bil mode and Bil value, respectively. First, the visibility of the Bil mode was validated for a bilirubin solution and bile concentrations ranging from 0...

Gastrinomas are pancreatic or duodenal endocrine tumors that secrete excess gastrin, which causes gastroesophageal reflux disease, peptic ulcers, and chronic diarrhea. Due to the rarity of the disease, nonspecific symptoms, and the outstanding effect of proton pump inhibitors, diagnosing gastrinomas is difficult. Here, we present the case of a 58-year-old woman who had a duodenal gastrinoma that caused rare but critical events, including esophageal perforation, necrotizing esophagitis, and severe esophageal stricture...

BACKGROUND: Yukgunja-tang (YGJ) is an herbal prescription used to treat the symptoms of gastroesophageal reflux disease (GERD). Although many preclinical and clinical studies on YGJ have been conducted on GERD, there is a lack of evidence from blinded studies to exclude placebo effects. Therefore, this protocol proposes a clinical trial that is single-centered, randomized, double-blinded, double-dummy to objectively evaluate the efficacy and safety of co-administered YGJ and rabeprazole (RPZ) in patients with GERD previously treated with proton pump inhibitors (PPIs) and still experiencing symptoms...

PURPOSE: Only limited studies have depicted the unique features and management of refractory chronic cough (RCC) and unexplained chronic cough (UCC). These led to the initiation of this study, which reported the demographic characteristics, manifestations, and long-term outcomes on a large series of consecutive RCC/UCC patients, providing a guideline-led real-world clinical experience. METHODS: Retrospective baseline information was obtained from Clinical Research Database (January 2016 to May 2021)...

Background: Chronic cough (CC), a cough that lasts > 8 weeks, has an overall prevalence of 5-11% in adults, peaking between 60 and 80 years of age. Of the 15% of patients who remain undiagnosed or refractory to treatment, two thirds are women. Objective: The objective was to present an updated evidence-based algorithmic approach for evaluating and managing CC, with emphasis on treatment modalities for refractory CC. Methods: A literature search was conducted of medical literature data bases for guidelines, position papers, systematic reviews, and clinical trials from January 2022 to June 2023, on the evaluation and management of CC...

OBJECTIVES: Anti-reflux mucosectomy (ARMS) and anti-reflux mucosal ablation (ARMA) were developed as interventions for proton pump inhibitor (PPI)-refractory/-dependent gastroesophageal reflux disease (GERD). Although ARMS and ARMA are established treatments for PPI-refractory GERD, reliance on natural healing for ulcer scar formation introduces uncertainty and bleeding risk. To address these issues, we introduced a novel approach called anti-reflux mucoplasty (ARM-P), which involves immediate closure of mucosal defects following mucosectomy...

Gastroesophageal reflux disease (GERD) is a clinical condition in which gastric reflux causes symptoms or damage to the esophageal mucosa. It is managed with proton pump inhibitors, however, up to 45% of patients with suspected GERD are refractory to treatment. It is necessary to establish a true GERD diagnosis by means of a digestive endoscopy, which does not show lesions in approximately 70% of patients. In this scenario, it is necessary to perform an esophageal pH-impedance measurement, a procedure that allows to determine whether exposure to gastric acid is pathological...

Gastrinomas are the most common neuroendocrine tumors worldwide and cause a clinical syndrome known as Zollinger-Ellison Syndrome (ZES). Increased acid production resulting from elevated gastrin levels contributes to symptoms such as abdominal pain, heartburn, and diarrhea. However, the non-specificity and overlap in the symptoms with idiopathic peptic ulcer disease and gastroesophageal reflux disease (GERD) can lead to delayed diagnosis. In this case, we describe a patient with a past medical history of GERD and a perforated gastric ulcer who continued to experience symptoms of dyspepsia and had a subsequent esophageal perforation, despite H...

BACKGROUND: Belching disorders and rumination syndrome (RS) are disorders of gut-brain interaction (DGBIs) in Rome IV. Belching disorders are composed of excessive gastric belching (GB) and supragastric belching (SGB). Excessive GB is related to physiological phenomenon whereas excessive SGB and RS are behavioral disorders. SUMMARY: A recent large internet survey found that prevalence of belching disorders and RS were 1% and 2.8%, respectively. It has been recognized that not a few patients with two behavioral disorders, excessive SGB and RS, could be misdiagnosed as proton pump inhibitors (PPI)-refractory gastroesophageal reflux disease (GERD)...

BACKGROUND: Many children respond to medical treatment for gastroesophageal reflux disease (GERD). However, some may require invasive intervention for refractory disease. Due to the lack of prognostic tools in children, this study aimed to develop a predictive model for refractory GERD. METHODS: A retrospective review was performed in children with symptoms of GERD at a university hospital. Refractory GERD was defined as an unresponsive disease after optimal treatment with medication for >8 weeks...

BACKGROUND AND AIM: Anti-reflux mucosal ablation (ARMA) is an emerging endoscopic treatment aimed at enhancing the gastroesophageal junction flap valve. This study aimed to evaluate its feasibility, effectiveness, and safety. METHODS: Between May 2018 and December 2022, patients with gastroesophageal reflux disease (GERD) symptoms refractory to acid suppression medications or those dependent on such medications were enrolled for ARMA. This retrospective analysis utilized prospectively collected data from an international bi-center study...

BACKGROUND: Gastroesophageal reflux disease (GERD) affects a significant proportion of individuals, with life stress being a contributing factor. This study aimed to investigate the correlation between psychosomatic evaluations, heart rate variability (HRV), and GERD in a cohort of individuals. Additionally, the study aimed to analyze the sequencing changes following proton pump inhibitor (PPI) treatment and identify predictive factors associated with refractory GERD. METHODS: A prospective cohort of 105 individuals with reflux esophagitis and a control group of 50 participants without acid reflux symptoms were enrolled...

BACKGROUND: An esophageal anastomotic stricture (EAS) after an esophageal atresia surgery occurs in approximately 4-60% of the cases, and its first-line therapy includes balloon dilatation. Oral balloon dilatation cannot be performed in some EAS cases; conversely, even if dilatation is possible, these strictures recur in some cases, necessitating a surgical procedure for repairing the stenosis. However, these procedures are invasive and have short- and long-term complications. If an EAS recurs repeatedly after multiple balloon dilations, gastroesophageal reflux disease (GERD) may be the underlying cause...

Chronic cough (CC) is associated with many conditions, so identifying contributing causes poses a diagnostic challenge. However, guidelines written for US physicians do not explicitly outline suggested roles for primary care providers (PCPs) in the approach to patients with CC, including refractory or unexplained CC. The objective of this review is to describe the role of PCPs in the diagnosis and treatment of CC in adults. This narrative review draws upon literature (identified via a PubMed search performed January 9, 2023, using primary care/disease state-related terms) and expertise from specialist physicians to provide recommendations for CC management in primary care...

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 2.0 provides a modern definition of actionable GERD, where evidence from oesophageal testing supports revising, escalating or personalising GERD management for the symptomatic patient...

BACKGROUND: Post-surgical macular edema (ME) is a common cause of prolonged visual impairment. Here we report on the feasibility and clinical outcomes from the use of a novel suprachoroidal microcatheter to treat post-surgical chronic ME by the posterior suprachoroidal placement of a triamcinolone acetonide (TA) suspension. METHODS: Two patients were catheterized with the Oxulumis suprachoroidal delivery system on two separate occasions starting 5 and 10 mm posterior to the limbus...

BACKGROUND: Systemic sclerosis (SSc) patients often become refractory to proton pump inhibitors (PPI)-a standard treatment for gastroesophageal reflux disease (GERD)-and intolerant to PPI in combination with domperidone. PPI with alginic acid is an alternative treatment option, but alginic acid is costly. OBJECTIVES: We compared the costs and effectiveness of alginic acid plus PPI versus standard treatments (PPI with/without antacids as needed and lifestyle modifications) for GERD in SSc patients unsuitable for, or intolerant to, domperidone...

PURPOSE: The Korean Chronic Cough Registry study was initiated to characterize patients with chronic cough (CC) and investigate their outcomes in real-world clinical practice. This report aims to describe the baseline cohort profile and study protocols. METHODS: This multicenter, prospective observational cohort study included newly referred CC patients and those already being treated for refractory or unexplained chronic cough (RUCC). Cough status was assessed using a visual analog scale, the Leicester Cough Questionnaire (LCQ), and the Cough Hypersensitivity Questionnaire (CHQ)...
