Notwithstanding the definite aetiopathogenetic path of certain diseases, the relationship between Helicobacter pylori (H. pylori) and Barrett’s esophagus (BE), a condition that increases the risk for dysplasia and consequently adenocarcinoma of the distal esophagus and esophagogastric junction, remains uncertain. This paper reviews the current scientific literature with emphasis on the protective correlation between H. pylori infection and BE and demonstrates that a causal relationship has not been disproved with certainty...

BACKGROUND: Transient lower esophageal sphincter relaxations (TLESRs) induced by gastric distension are modulated by the metabotropic glutamate receptor 5 (mGluR5) that influences the vagal reflex loop. We therefore aimed to examine the effects of the selective mGluR5 antagonist mavoglurant (AFQ056) on the number of TLESRs in dogs and reflux episodes in patients with gastroesophageal reflux disease (GERD). METHODS: In a dog model, the number of meal-induced TLESRs was determined after intravenous (0...

BACKGROUND: Esophageal hypersensitivity is important in gastro-esophageal reflux disease (GERD) patients refractory to acid-suppressive therapy. Stress affects visceral sensitivity and exacerbates heartburn in GERD. Peripheral CRH is a key mediator of the gut stress response. We hypothesize that CRH increases esophageal sensitivity and alters esophageal motility in health. METHODS: Esophageal sensitivity to thermal, mechanical, electrical and chemical stimuli was assessed in 14 healthy subjects after placebo or CRH (100μg IV)...

OBJECTIVE: Gastroesophageal reflux disease (GERD) clinically predisposes to columnar Barrett's metaplasia (BM) in the distal esophagus. We demonstrate evidence supporting cellular origin of BM from reprograming or trans-commitment of resident normal esophageal squamous (NES) epithelial cells in response to acid and bile exposure using an in vitro cell culture model. DESIGN: The hTERT-immortalized NES cell line, NES-B10T, was exposed 5 min/day to Acid and Bile (A+B) mixture for 30 weeks...

BACKGROUND: Laparoscopic anti-reflux surgery (LARS) is generally the treatment of choice for patients with gastroesophageal reflux disease (GERD). This report describes our experiences in performing LARS on patients with GERD, and focuses retrospectively on the pathophysiology of individual patients and the current status of Japanese patients who have undergone LARS. We demonstrate that patients with non-erosive reflux disease resistant to proton pump inhibitors (PPI-resistant NERD) and high-risk giant hernia, whom we are sometimes hesitant to treat surgically, can be safely and successfully treated with LARS (depending on the pathophysiology of individual patients)...

INTRODUCTION: Large esophageal hiatal hernias occur most commonly in elderly patients with comorbidities, in whom even an elective surgery cannot be performed without high risks. Although fundoplication is recommended for esophageal hiatal hernia repair, we prefer not to limit our options to fundoplication, as obstruction is a frequent main complaint. We favor an anterior gastropexy approach instead to perform anti-reflux surgery and prevent recurrent protrusion and torsion of the incarcerated organ with minimal risk...

Medical treatment is effective in the majority of patients with gastroesophageal reflux disease (GERD). Lifestyle modifications are often recommended for patients with GERD, although the data supporting lifestyle recommendations are limited. Antacids are often used to treat the symptoms of GERD, but their effect is short-lived. H2-receptor antagonists and proton-pump inhibitors provide more effective options for remission of GERD symptoms and healing of esophagitis. Prokinetic medications (e.g., metoclopramide) have not been proven to help in the control of symptoms...

OBJECTIVE: Gastroesophageal reflux disease (GERD) is a common disease which can cause troublesome symptoms and affect quality of life. In addition to esophageal complications, GERD may also be a risk factor for extra-esophageal complications. Both GERD and coronary artery disease (CAD) can cause chest pain and frequently co-exist. However, the association between GERD and acute myocardial infarction (AMI) remain unclear. The purpose of the study was to compare the incidence of acute myocardial infarction in GERD patients with an age-, gender-, and comorbidity matched population free of GERD...

Gastroesophageal reflux disease (GERD) has a large economic burden with important complications that include esophagitis, Barrett's esophagus, and adenocarcinoma. Despite endoscopy, validated patient questionnaires, and traditional ambulatory pH monitoring, the diagnosis of GERD continues to be challenging. Areas covered: This review will explore the difficulties in diagnosing GERD with a focus on new developments, ranging from basic fundamental changes (histology and immunohistochemistry) to direct patient care (narrow-band imaging, impedance, and response to anti-reflux surgery)...

BACKGROUND: After achalasia treatment, a subset of patients has poor esophageal emptying without having symptoms. There is no consensus on whether to pre-emptively treat these patients. We hypothesized that, if left untreated, these patients will experience earlier symptom recurrence than patients without stasis. METHODS: 99 treated achalasia patients who were in clinical remission (Eckardt ≤3) at 3 months after treatment were divided into two groups, based on presence or absence of esophageal stasis on a timed barium esophagogram performed after 3 months...

Background and study aims Esophageal mucosal breaks in patients with reflux esophagitis (RE) have a unique circumferential distribution. However, the specific location of mucosal breaks during recurrence of RE remains unclear. We investigated the circumferential distribution of mucosal breaks in patients with recurrent RE and compared their location to that noted at the initial diagnosis. Patients and methods We retrospectively enrolled patients with recurrent RE with Los Angeles (LA) grade A-C who were treated at our University Hospital between July 1996 and June 2014...

BACKGROUND/AIMS: Human Papilloma Virus (HPV) infection can be a predisposing condition for the development of squamous cell papilloma (SCP) of the esophagus, which can progress to dysplasia and to carcinoma as a result of chronic infection. The aim of the present study was to search for the presence of HPV in the esophageal SCP, and to genotype the detected HPV. MATERIALS AND METHODS: Data from patients with definite diagnosis of SCP of the esophagus were identified from pathology records for two years period at different Hospitals...

INTRODUCTION: One anastomosis gastric bypass (OAGB) demonstrated results similar to traditional Roux-en-Y procedures [1-3], in terms of weight loss and resolution of obesity-related comorbidities. The main controversy regarding OAGB is the concern for an association between biliary alkaline gastritis and esophageal or gastric cancer raised by some studies [4]. METHODS: We present the case of a 51-year-old woman with a BMI of 41 kg/m2 who underwent a laparoscopic OAGB in 2014...

Classic gastroenterological diagnostic tools have proven to be insufficient in identifying the causal relationship between extra-esophageal symptoms and presumed pathological reflux activity. Some new methodological approaches, such as functional endoscopy (video panendoscopy, VPE), are considered to be helpful. However, there are currently no data objectively verifying the success of this method. In a previous study, we found a good correlation between the reflux symptom index (RSI) according to Belafsky and endoscopic findings...

BACKGROUND: Gastroesophageal reflux disease (GERD) is common in patients with obesity. Diagnosing GERD is important as bariatric operations have different influence on GERD. We assessed reflux symptoms and objective findings prior to surgery. METHODS: Work-up included esophageal symptoms quantification by VAS-scores, esophagogastroduodenoscopy (EGD) and 24-h impedance-pH (imp-pH) monitoring off PPI therapy. Imp-pH was classified as abnormal if either %time pH<4 was abnormal, total number of reflux episodes was elevated or symptom index (SI) was positive...

BACKGROUND: Proton pump inhibitors (PPIs) are a class of medications that reduce acid secretion and are used for treating many conditions such as gastroesophageal reflux disease (GERD), dyspepsia, reflux esophagitis, peptic ulcer disease, and hypersecretory conditions (e.g. Zollinger-Ellison syndrome), and as part of the eradication therapy for Helicobacter pylori bacteria. However, approximately 25% to 70% of people are prescribed a PPI inappropriately. Chronic PPI use without reassessment contributes to polypharmacy and puts people at risk of experiencing drug interactions and adverse events (e...

BACKGROUND: Many asthmatics remain sub-optimally controlled despite current treatments. Reasons include comorbidities that could aggravate asthma, including gastro-esophageal reflux (GER). We aimed to investigate whether aspiration occurs in asthmatic patients and if so does it correlate with asthma control. METHODS: Patients had ACQ-7, FeNO, and spirometry performed to characterize their level of asthma control. Barium swallow with provocation was performed to assess for predisposition to aspiration...

INTRODUCTION: Despite consensus eosinophilic esophagitis (EoE) statement published in 2011 calling for a 2-month trial of protons pump inhibitor (PPI), the guidelines are not followed by many. We studied the practice patterns in our community and response to a PPI retrial in patients previously diagnosed with "idiopathic EoE." METHODS: All patients presenting to the senior author's practice with suspected EoE from 2011 to 2015. Two cohorts were studied: (1) patients diagnosed in the community as "idiopathic EoE"; (2) treatment naïve patients given a PPI trial at University of South Florida...

BACKGROUND: The Orbera intragastric balloon (IGB) has been approved by the US Food and Drug Administration for use in patients with a body mass index (BMI) between 30 and 40 kg/m(2) and is in wide use worldwide as a primary and bridge obesity management tool. The balloon filling volume (BFV) ranges between 400 and 700 mL of saline. Our objective was to determine whether there is an association between BFV and clinically relevant endpoints, namely weight loss outcomes, balloon tolerability, and adverse events...
