To determine the relationship between baseline impedance levels and gastroesophageal reflux, we retrospectively enrolled 110 patients (54 men and 56 female; mean age, 51 ± 14 years) with suspected gastroesophageal reflux disease (GERD) who underwent 24-h multichannel intraluminal impedance and pH monitoring. Patients were stratified according to symptom (typical or atypical) and reflux types (acid reflux, nonacid reflux [NAR], or no abnormal reflux). Mean nocturnal baseline impedance (MNBI) were measured 3 cm (distal esophagus) and 17 cm (proximal esophagus) above the lower esophageal sphincter...

AIM: In 2004 wide variation in the investigation and management of gastro-oesophageal reflux (GOR) of infants on UK major neonatal units was demonstrated. Our aim was to re-survey neonatal practitioners to determine current practice and whether it was now evidence based. METHODS: A questionnaire was sent to all 207 UK neonatal units. RESULTS: Responses were obtained from 84% of units. The most frequent "investigation" was a trial of therapy (83% of units); pH studies were used in 38%, upper GI contrast studies in 19% and multichannel intraluminal impedance (MII)/pH studies in 5%...

A relevant percentage of non-erosive reflux disease (NERD) is refractory to proton pump inhibitors (PPIs) treatment. Multichannel intraluminal impedance pH (MII-pH) monitoring should give useful pathophysiological information about refractoriness. Therefore, our aim was to assess whether this technique could be useful to guide a 'tailored' therapy in refractory NERD. We retrospectively recruited NERD patients undergoing MII-pH monitoring for unsuccessful treatment. All patients had undergone upper endoscopy, and those with erosive esophagitis were excluded...

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...

OBJECTIVES/HYPOTHESIS: Empiric proton pump inhibitor (PPI) trials for laryngopharyngeal reflux (LPR) are common. A majority of the patients respond to acid suppression. This work intends to evaluate once-daily, 40 mg omeprazole and once-nightly, 300 mg ranitidine (QD/QHS) dosing as an alternative regimen, and use this study's cohort to evaluate empiric regimens prescribed for LPR as compared to up-front testing with pH impedance multichannel intraluminal impedance (MII) with dual pH probes and high-resolution manometry (HRM) for potential cost minimization...

BACKGROUND: Combined pH-impedance monitoring has been suggested as the investigation of choice for diagnosing gastro-oesophageal reflux in children. Although it is superior to oesophageal pH monitoring in detecting all types of reflux episodes (acid, weakly acidic and alkaline) with the ability to evaluate symptom association with reflux events, it is still limited by the lack of true paediatric normal value and the high cost involved (equipment and personnel). OBJECTIVE: To produce a position statement on behalf of the Motility Working Group of the British Society of Paediatric Gastroenterology, Hepatology and Nutrition on the indications and practical application of combined oesophageal pH-impedance monitoring in children...

The clinical manifestations of non-erosive gastroesophageal reflux disease (NERD) are multiple and heterogeneous, and differ according to age and individual susceptibility. Weakly acidic reflux and the presence of gas in the refluxate could be relevant in the pathogenesis of symptoms. We present the case of a 3-year and 5-month-old child who came to the hospital with recurrent paroxysmal manifestations without fever assessed. The positive diagnosis was made using pH-metry associated with multichannel intraluminal impedance and glucose respiratory breath test, a new technique that allows positive diagnosis as well as establishes important connections regarding gas reflux and clinical symptomatology described by the patient...

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: Only a few reports focused on esophageal motility in patients with proton pump inhibitor (PPI)-refractory nonerosive reflux disease (NERD) and there has been no established strategy for treatment. OBJECTIVE: To clarify the characteristics of esophageal motility in patients with PPI-refractory NERD, we evaluated esophageal function using combined multichannel intraluminal impedance and esophageal manometry (MII-EM). In addition, we evaluated the efficacy of rikkunshito (RKT), which is a gastrointestinal prokinetic agent...

Conventional 24-h pH monitoring is the gold standard for the diagnosis of non-erosive, non-acidic gastro-esophageal reflux disease. Multichannel Intraluminal Impedance (MII) analysis markedly improves diagnostic accuracy of non-erosive, non-acidic gastro-esophageal reflux disease. However, MII catheters are more expensive than standard catheters. This study aimed to determine the rates of acid or non-acid reflux and by making a retrospective projection, to predict the costs of two algorithms. We retrospectively reviewed the medical data of 102 patients who presented to our hospital with suspected non-erosive GERD and underwent 24 h impedance/pH-monitoring...

BACKGROUND: The modalities for evaluating acid reflux in medical care for gastroesophageal reflux disease (GERD) include conventional pH (C-pH), wireless pH (Bravo(®)) and multichannel intraluminal impedance pH (MII-pH), which have been reported to vary with respect to the duration of acid reflux. In this study, we examined the difference between the acid reflux in C-pH and MII-pH among patients with GERD. METHODS: Prior to initial laparoscopic fundoplication carried out on 297 cases from December 1994 to April 2016, an upper gastrointestinal endoscopy and C-pH or MII-pH were conducted...
