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: Gastroesophageal reflux (GER) has been associated with idiopathic pulmonary fibrosis (IPF). Pathogenesis may be related to chronic micro-aspiration. We aimed to assess objective measures of GER on multichannel intraluminal impedance and pH study (MII-pH) and their relationship with pulmonary function testing (PFT) results, and to compare the performance of pH/acid reflux parameters vs corresponding MII/bolus parameters in predicting pulmonary dysfunction in IPF. METHODS: This was a retrospective cohort study of IPF patients undergoing prelung transplant evaluation with MII-pH off acid suppression, and having received PFT within 3 months...

BACKGROUND: Esophageal intraluminal baseline impedance reflects the conductivity of the esophageal mucosa and may be an instrument for in vivo evaluation of mucosal integrity in children with gastroesophageal reflux disease (GERD). Laparoscopic antireflux surgery (LARS) is a well-established treatment option for children with proton pump inhibitory (PPI) therapy resistant GERD. The effect of LARS in children on baseline impedance has not been studied in detail. The aim of this study was to evaluate the effect of LARS on baseline impedance in children with GERD...

M M J Singendonk, M A Benninga, M P van Wijk
Recently, multichannel intraluminal impedance (MII) monitoring was added to the repertoire of tests to evaluate the (patho)physiology of gastroesophageal reflux (GER) in children. Its advantage above the sole monitoring of the esophageal pH lies in the ability of the detection of both acid and nonacid GER and to discern between liquid and gas GER. Currently, combined 24 h pH-MII monitoring is recommended for evaluation of gastro-esophageal reflux disease (GERD) and its relation to symptoms in infants and children, despite the lack of reference values in these age groups...

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...

BACKGROUND/AIMS: Respiratory symptoms are often associated with gastroesophageal reflux disease (GERD). Although the role of multichannel intraluminal impedance-pH (MII-pH) monitoring in GERD is clear, little is known regarding the characteristics of patients with respiratory symptoms based on MII-pH monitoring and anti-reflux therapy. We evaluated a cohort of GERD patients to identify the MII-pH parameters of GERD-related respiratory symptoms and to assess the anti-reflux therapy outcomes...

OBJECTIVE/HYPOTHESIS: The objective of this study was to determine the validity of our laryngopharyngeal reflux (LPR) diagnostic system from our previous study (Witt et al.) against the results of a standard pH probe monitoring. We hypothesized that subjects with abnormal pH probe results demonstrate color and texture abnormalities that would be classified as LPR according to artificial neural network (ANN) analysis. STUDY DESIGN: Retrospective analysis. METHODS: Eighty-two subjects, including 18 pH-positive, 11 pH-negative, and 53 control subjects were tested for LPR through multichannel intraluminal impedance 24-hour pH (MII-24pH) monitoring...
