BACKGROUND: Ano-rectal manometry (ARM) is the most commonly performed investigation for assessment of anorectal dysfunction. Its use is supported by expert consensus documents and international guidelines. Variation in technology, data acquisition, and analysis affect results and clinical interpretation. This study examined variation in ARM between institutions to establish the status of current practice. METHODS: A 50-item web-based questionnaire assessing analysis and interpretation of ARM was distributed by the International Anorectal Physiology Working Group via societies representing practitioners that perform ARM...

Introduction and aims High-resolution esophageal manometry (HRM) has improved the diagnostic work-up of esophageal motility disorders. Simultaneous evaluation of bolus clearance delivers useful information about the function of tubular esophagus. We assessed bolus clearance in a combined HRM-impedance examination for esophagogastric junction outflow obstruction (EGJOO) in comparison to achalasia patients. The collected data were assessed in a retrospective analysis. Patients and methods After gastroscopy excluded a mechanical esophageal or gastric obstruction, 142 consecutive patients underwent combined HRM-impedance examination...

AIMS: We evaluated associations of esophagogastric junction (EGJ) metrics as an anti-reflux barrier with impedance-pH, endoscopic esophagitis, and lower esophageal sphincter (LES) metrics. METHODS: We reviewed high resolution manometry data from consecutive patients with GERD symptoms who underwent impedance-pH and endoscopy, and asymptomatic volunteers. The EGJ contractile integral (CI) was calculated as the mean contractile integral/second during three respiratory cycles...

BACKGROUND: Based on Chicago Classification version 3.0, the disorders of esophagogastric junction outflow obstruction (EGJOO) include achalasia (types I, II and III) and EGJOO. Although no curative treatments are currently available for the treatment of the disorders of EGJOO, medical treatments, endoscopic pneumatic dilation (PD), laparoscopic Heller myotomy (LHM), and per-oral endoscopic myotomy (POEM) are usually the sought-after modes of treatment. Since the etiology and pathogenesis might vary depending on the types of EGJOO disorders, treatment strategies should be considered based on those subtypes...

Background/Aims: Little research has been done to evaluate the effect of stress in exacerbating the symptoms associated with gastroesophageal reflux (GER). We aimed to investigate the effect of acute stress on esophageal motility and GER parameters in healthy volunteers. Methods: A total of 10 (M:F = 8:2, median age 34 years-old) healthy volunteers without any recurrent gastrointestinal symptoms participated in this study. They underwent esophageal high-resolution manometry with 10 wet swallows (Experiment I) and esophageal impedance-pH monitoring (Experiment II) in the basal period and in the stress period...

BACKGROUND: Esophageal achalasia can be classified on the grounds of three distinct manometric patterns that correlate well with final outcome after laparoscopic Heller-Dor myotomy (LHM). No analytical data are available, however, on the postoperative picture and its possible correlation with final outcome. The aims of this study were: (a) to investigate whether manometric patterns change after LHM for achalasia; (b) to ascertain whether postoperative patterns and/or changes can predict final outcome; and (c) to test the hypothesis that the three known patterns represent different stages in the evolution of the disease...

BACKGROUND: The differential diagnosis of intractable reflux in children includes rumination syndrome, but confirming the diagnosis using antroduodenal manometry is invasive, is costly, and requires anesthesia. High-resolution esophageal manometry with impedance (HRM-MII) overcomes these limitations, and the goal of this study is to validate the use of HRM-MII as a diagnostic tool for rumination and to describe the subtypes of pediatric rumination. METHODS: We reviewed the HRM-MII tracings of 21 children presenting with symptoms of intractable reflux in whom rumination was being considered...

NeuroGUT is a EU-funded initial training network (ITN) of 14 research projects in neurogastroenterology that have employed an equal number of early-stage researchers. Neurogut trainees have-among other activities-attended an international conference on irritable bowel syndrome (IBS) in Bologna in 2016 and were asked to critically review and evaluate the current knowledge on IBS for their respective research activities, and to state what they were missing. Most appreciated were the topics brain imaging of gut activity, the role of the gut microbiota, the pharmacology of gut functions, the IBS-IBD interrelation, the new Rome IV criteria, the role of gas, and the placebo response in functional disorders...

Gastroesophageal reflux disease (GERD) is nowadays a highly prevalent, chronic condition, with 10% to 30% of Western populations affected by weekly symptoms. Many patients with mild reflux symptoms are treated adequately with lifestyle modifications, dietary changes, and low-dose proton pump inhibitors (PPIs). For those with refractory GERD poorly controlled with daily PPIs, numerous treatment options exist. Fundoplication is currently the most commonly performed antireflux operation for management of GERD...

BACKGROUND: Three-dimensional high-resolution anorectal manometry (3DHRAM), used for exploring anorectal disorders, was recently developed, providing interesting topographic data for the diagnosis of pelvic floor disorders such as excessive perineal descent. The aim of our study was to define a diagnostic strategy based on selected 3DHRAM parameters to identify rectal intussusceptions (RI), considering conventional defecography (CD) as the gold standard. METHODS: All patients referred to our center in the previous 6 months for 3DHRAM to explore fecal incontinence or constipation, and who previously achieved CD, were eligible...

BACKGROUND: The epidemiology of chronic constipation (CC) skews toward female predominance, yet men make up an important component of those suffering from CC. We sought to determine whether there are sex-specific differences in symptoms and physiologic parameters on anorectal manometry (ARM). METHODS: We performed a case-control analysis of sequential men and age-matched women (2:1 ratio) presenting for ARM as part of the evaluation of CC. We collected physiologic parameters derived from 3D high-resolution ARM in addition to the ROME III constipation module and the Pelvic Floor Distress Inventory 20 (PFDI-20) questionnaires...

BACKGROUND: Patients with dysphagia may be diagnosed with impaired lower esophageal sphincter (LES) relaxation and treated with pneumatic dilation (PD), stretching and tearing LES muscle fibers. Esophageal perforation has been reported to be as high as 10%. We conducted a retrospective study to evaluate the perforation rate of PD when used for impaired relaxation of the LES using current techniques. METHODS: A chart review was conducted to identify patients referred for esophageal manometry by high-resolution manometry and later received PD from January 2013 to April 2016...
