OBJECTIVES/HYPOTHESIS: Aspiration of gastric refluxate is one of the most commonly observed complications among long-term nasogastric tube (NGT) fed patients. The upper esophageal sphincter (UES) pressure barrier is the main defense mechanism against pharyngeal reflux of gastric contents. Our objective was to investigate the efficacy and safety of the UES assist device (UES-AD) in preventing gastric reflux through the UES in long-term NGT-fed patients. STUDY DESIGN: Self-Controlled Case series...

Alginate-based formulations are frequently used as add-on proton pump inhibitor (PPI) therapy to help control of heartburn and regurgitation. There are limited data regarding the mechanisms and effects of alginate-based formulations. We aimed to evaluate the effects of the sodium alginate intake and its likely temporal relations on intraesophageal reflux events by MII-pH in patients with and without hiatal hernia (HH). Fifty GERD patients (18 with HH, 32 without HH) with heartburn or regurgitation once a week or more common were included...

BACKGROUND: The diagnosis of laryngopharyngeal reflux is currently based on a combination of the patient history of multichannel intraluminal impedance and ambulatory pH (MII-pH); however, none of these findings alone is specific for the diagnosis of laryngopharyngeal reflux. We aimed to compare the baseline characteristics and esophageal baseline impedance values between patients with and without laryngopharyngeal reflux symptoms. METHODS: We retrospectively analyzed data from two groups of patients with laryngopharyngeal reflux according to their reflux finding score (RFS) as scored by ENTs...

BACKGROUND: Rumination syndrome is characterized by recurrent regurgitation of recently ingested food into the mouth. Differentiation with other diagnoses and gastroesophageal reflux disease (GERD) in particular, is difficult. Recently, objective pH-impedance (pH-MII) and manometry criteria were proposed for adults. The aim of this study was to determine diagnostic ambulatory pH-MII and manometry criteria for rumination syndrome in children. METHODS: Clinical data and 24-hour pH-MII and manometry recordings of children with a clinical suspicion of rumination syndrome were reviewed...

Obesity increases the risk of gastroesophageal reflux disease (GERD). The majority of the reflux attacks occur postprandially. The influence of the speed of food intake on gastroesophageal reflux events is unclear in obese patients. To determine the influence of the speed of food intake on intraesophageal reflux events in obese patients with and without GERD. A total of 26 obese female patients were recruited. The patients underwent esophageal manometry to evaluate the upper limit of the lower esophageal sphincter and subsequently placement of a Multichannel intraluminal impedance-pH (MII-pH) catheter...

BACKGROUND AND AIM: Spinal kyphotic deformity occasionally results in gastroesophageal reflux disease (GERD). The effects of acid reflux on the esophagus in kyphotic patients are unclear, however, and it is unknown whether acid reflux, endoscopic GERD, and reflux-related symptoms improve following surgical spinal correction in these patients. Herein, we investigated the characteristics of GERD in kyphotic patients and the improvement in GERD following surgical correction. METHODS: In 48 patients with severe kyphotic deformity scheduled for surgical spinal correction, we conducted esophagogastroduodenoscopy, 24-h pH monitoring and three questionnaire surveys, including the frequency scale for the symptoms of GERD (FSSG)...

BACKGROUND: It has been previously demonstrated that patients with reflux esophagitis exhibit a significant impairment in the secretion of salivary protective components versus controls. However, the secretion of salivary protective factors in patients with nonerosive reflux disease (NERD) is not explored. The authors therefore studied the secretion of salivary volume, pH, bicarbonate, nonbicarbonate glycoconjugate, protein, epidermal growth factor (EGF), transforming growth factor alpha (TGF-α) and prostaglandin E2 in patients with NERD and compared with the corresponding values in controls (CTRL)...

BACKGROUND: One of the primary indications for reflux testing with multichannel intraluminal impedance with pH (pH-MII) is to correlate reflux events with symptoms such as cough. Adult and pediatric studies have shown, using cough as a model, that patient report of symptoms is inaccurate. Unfortunately, intraesophageal pressure recording (IEPR) to record coughs is more invasive which limits its utility in children. The primary aim of this study was to validate the use of acoustic cough recording (ACR) during pH-MII testing...

PURPOSE: A significantly compromised epidermal growth factor (EGF) secretion by basal parotid saliva may contribute to the development of Barrett's esophagus (BE). The rate of secretion of EGF as well as a wide spectrum of protective factors in total basal and stimulated saliva in BE patients remains to be explored. We therefore studied the rate of secretion of salivary buffers, glycoconjugate, protein, EGF, transforming growth factor α (TGFα) and prostaglandin E₂ (PGE₂), evoked by esophago-salivary reflex, in patients with BE and controls (CTRL)...

BACKGROUND: Cow's milk protein allergy (CMPA) is being seen more frequently on a daily basis in pediatric consultations. It shares symptoms with gastroesophageal reflux (GER), which can complicate the differential diagnosis. AIMS: To attempt to corroborate the presence of acid GER in children with CMPA, as well as to find a characteristic profile through the 24-hour pH monitoring study in children with GER and CMPA METHODS: The intraesophageal pH monitoring studies performed on 47 children with CMPA were reviewed...

BACKGROUND/AIMS: There is a general belief that gastroesophageal reflux attacks appear more frequently after quick meal, which is without powerful scientific basis, and the general advise to patients is to eat slowly. We aimed to determine whether the speed of eating has an impact on reflux attacks and symptoms in gastroesophageal reflux disease patients. MATERIALS AND METHODS: 24-h intraesophageal pH monitoring was performed to 60 patients with frequent gastroesophageal reflux disease symptoms (39 women) in a tertiary referral center...

BACKGROUND: The symptom improvement rate is low with proton pump inhibitors (PPIs) in nonerosive reflux disease (NERD). The underlying pathogenic mechanism is complex. Esophageal motility disorders (EMDs) are thought to be a factor, but their prevalence, type, symptoms and the role played by gastroesophageal reflux (GER) in symptom onset have not been fully investigated. AIM: To investigate the role of GER in symptom onset in PPI-refractory NERD patients with EMDs...

BACKGROUND: Low basal lower esophageal sphincter (LES) pressure and transient LES relaxations are major causes of gastroesophageal reflux disease (GERD). Pumosetrag, a novel selective partial 5HT3 receptor agonist, showed a promising effect on reducing reflux events in health. We aimed to evaluate the effect of pumosetrag on changes in reflux episodes, lower esophageal sphincter pressure (LESP), and specific symptoms in patients with GERD receiving a refluxogenic meal. METHODS: Patients with GERD, who developed heartburn and/or regurgitation after ingestion of a refluxogenic meal, were randomized to 1 of 3 dose levels of pumosetrag (0...

BACKGROUND: One of the primary reasons for referral for reflux testing is to correlate reflux events with symptoms such as cough. Adult studies have suggested that symptom recording is flawed and pediatricians feel this is an even more significant problem because there may be errors in both parental and patient reports. We hypothesize that intraesophageal pressure recording (IEPR) provides an objective method to identify coughs during reflux testing in children. METHODS: We recruited 20 children undergoing multichannel intraluminal impedance with pH (pH-MII) testing for the evaluation of cough...
