BACKGROUND: Gastroesophageal reflux disease is thought to predispose to adverse lung allograft outcomes. However, little is known about the burden of gastroesophageal reflux (GER) and gastroparesis in pediatric patients. In this study we describe the burden of reflux and gastroparesis in children undergoing lung transplant, and evaluates their impact on allograft survival and rejection incidence. METHODS: This study is a retrospective analysis of pediatric lung transplant recipients who had combined pH and multichannel intraluminal impedance testing (pH-MII) and gastric-emptying scans (GES)...

BACKGROUND: Motility disturbances of the esophagus and gastroesophageal reflux disease (GERD) are observed frequently in children after repair of congenital esophageal atresia with distal tracheoesophageal fistula (EA/TEF). Recently, in many pediatric surgical centers, thoracoscopic repair was introduced, which theoretically would change the postoperative course. OBJECTIVES: The goal of the study was to assess physical development, disease symptoms, and GERD symptom frequency in children who underwent thoracoscopic surgery of congenital EA/TEF...

BACKGROUND/AIMS: Symptoms suspicious of extraesophageal reflux (SSEER) include globus, chronic cough, mucous obstruction and hoarseness. Reports of conventional esophageal function tests and measurement of extraesophageal reflux (EER) in these patients are spare providing conflicting results. METHODS: In a prospective study we evaluated 60 patients with SSEER by esophageal function tests (esophageal manometry, combined 24 h pH - metry - impedance and oropharyngeal pH measurement, Dx - pH measurement) and esophagogastroduodenoscopy (EGD)...

INTRODUCTION: It is not yet clear if laparoscopic sleeve gastrectomy (LSG) causes newly onset gastroesophageal reflux (GERD) or worsens already existing GERD. This is due to the absence of prospective studies using objective assessment measures of GERD such as pH monitoring. Our study aims at assessing GERD 1-year post-LSG procedure for obesity. MATERIALS AND METHODS: Twelve asymptomatic obese patients were studied prospectively by using 24-h multichannel intraluminal impedance-pHmetry (MIIpH) pre- and 12 months post-LSG...

Gastroesophageal reflux disease (GERD) is a common disorder of the gastrointestinal tract. In the last few decades, new technologies have evolved and have been applied to the functional study of the esophagus, allowing for the improvement of our knowledge of the pathophysiology of GERD. High-resolution manometry (HRM) permits greater understanding of the function of the esophagogastric junction and the risks associated with hiatal hernia. Moreover, HRM has been found to be more reproducible and sensitive than conventional water-perfused manometry to detect the presence of transient lower esophageal sphincter relaxation...

BACKGROUND: Gastroesophageal reflux (GER) is the retrograde flow of gastric contents into the esophagus and may induce a variety of complications. Endoscopically visible breaks in the distal esophageal mucosa are the most reliable evidence of reflux esophagitis. Combined multichannel intraluminal impedance and pH-metry (MII-pH) is a technique that enables monitoring of GER independent of its acidity. The aim of this study is to investigate the GER patterns in children with the aid of MII-pH monitoring and determine the correlation between endoscopically proven reflux esophagitis and reflux types by MII-pH monitoring...

Previously published studies have indicated that gastroesophageal reflux (GER) disease is common in pediatric patients with cystic fibrosis. The aim of the present study was to get insight into the incidence of GER and to characterize the nature of reflux episodes in children with cystic fibrosis. This was a multicenter, prospective study of children with cystic fibrosis older than 18 months. Forty four consecutive patients (22 boys, mean age 10.4 ± 3.6, range 3.0-17.8 years) were enrolled into the study...

BACKGROUND: Although several studies reporting normal values of 24h multichannel intraluminal impedance pH (MIIpH) have been published, none of them has ever studied obese individuals. The purpose of this study is to determine overall frequency and duration of reflux episodes (acid and non-acid, supine-upright, post and preprandial) in obese asymptomatic volunteers. METHODS: Obese volunteers were enlisted during their preoperative evaluation for bariatric surgery...

BACKGROUND: Both esophageal atresia (EA) and duodenal atresia (DA) involve deficient anti-reflux barrier, poor esophageal function and eventually, duodenogastric reflux. This study aims at examining the upper gastrointestinal functional status in a cohort of patients with both EA and DA. METHODS: A retrospective survey of patients treated for EA and DA between 1965 and 2012 was conducted. Clinical charts, office visits, imaging, upper gastrointestinal endoscopy and esophageal pH metry/impedance were used to assess the long-term condition of the esophagus, the presence of gastroesophageal reflux disease (GERD) and/or the need for fundoplication...

BACKGROUND/AIMS: Globus, chronic cough, mucous obstruction and hoarseness are frequently interpreted and classified as manifestation of extraesophageal reflux (EER) or laryngopharyngeal reflux (LPR). Recent studies have indicated that ablation of heterotopic gastric mucosa of the proximal esophagus (HGMPE) by argon plasma coagulation (APC) significantly reduces EER/LPR symptoms. METHODS: In a prospective study we evaluated 14 patients with HGMPE and EER/LPR symptoms by esophageal function testing (esophageal manometry, combined 24 h-pH-metry-impedance - oropharyngeal-pH measurement), standardized symptom questionnaire (visual analogue scales), and esophagealgastroduodenoscopy (EGD)...

OBJECTIVES: It is unclear how diagnostic tests for gastroesophageal reflux disease (GERD) in children relate to the course of symptoms during follow-up. METHODS: During 1 year, all children (ages 0-18 years), who underwent pH-metry and/or pH multichannel intraluminal impedance (MII), were included after written informed consent was obtained. pH-metry and pH-MII test characteristics, such as reflux index (RI, % time that esophageal pH < 4), were obtained from the measurements...

BACKGROUND: 24-hour esophageal pH-impedance (pH-MII) is not totally reliable for laryngopharyngeal reflux (LPR). Oropharyngeal (OP) pH-monitoring with the Dx-pH probe may detect LPR better. The correlation between these two techniques is not thoroughly established. Aim of this study is to examine the correlation between OP pH-metry and esophageal pH-MII monitoring. METHODS: Thirty-six consecutive patients with suspected gastroesophageal reflux disease-related extra-esophageal symptoms were evaluated using 24-h OP-pH and concomitant esophageal pH-MII monitoring...

BACKGROUND: In infants, apneas can be centrally mediated, obstructive or both and have been proposed to be gastroesophageal reflux (GER) induced. Evidence for this possible association has never been systematically reviewed. PURPOSE: To perform a systematic review using PubMed, EMBASE and Cochrane databases to determine whether an association between GER and apnea in infants exists. Studies with n ≥ 10 infants, aged <12 months, were included. GER had to be studied by pH-metry or pH-impedancemetry...

BACKGROUND: To date, therapeutic guidelines and pattern of reflux for patients with no-dysplasia (ND) or low-grade dysplasia (LGD) Barrett's esophagus (BE) remain unclear. We aimed to analyze pattern of reflux and regression of ND- or LGD-BE after medical and surgical treatment. METHODS: We studied a cohort of ND- and LGD-BE patients who underwent laparoscopic total fundoplication and a cohort of ND- and LGD-BE patients managed medically. Patients were matched for age, sex, and disease duration...

AIM: This study was designed to investigate about findings of Impedance pH-monitoring in patients with atypical symptoms of GERD. BACKGROUND: The routine treatment with proton pump inhibitors is not very effective in patients with atypical symptoms of Gastro-Esophageal Reflux Disease (GERD). It may be due to non-acid reflux which cannot be monitored using common methods such as pH-metry. Therefore, in these patients combinational procedure of multi channel intraluminal impedance and pH monitoring has been suggested as a new approach...

AIM: To identify objective and subjective predictors for the reliable diagnosis of gastroesophageal reflux disease (GERD) and the response to proton pump inhibitor (PPI) therapy. METHODS: Retrospectively, 683 consecutive patients suspected for GERD who underwent pH-metry/impedance measurement (pH/MII) were analyzed. All patients had previously undergone standard PPI treatment (e.g., pantoprazole 40 mg/d or comparable). Four hundred sixty patients were at least 10 d off PPIs (group A), whereas 223 patients were analyzed during their ongoing PPI therapy (group B)...
