INTRODUCTION Although inability to belch has previously been linked to dysfunction of the upper esophageal sphincter (UES), its underlying pathogenesis remains unclear. Our aim was to study mechanisms underlying inability to belch and the effect of UES botulinum toxin (botox) injections in these patients. METHODS We prospectively enrolled consecutive patients with symptoms of inability to belch. Patients underwent stationary high-resolution impedance manometry (HRIM) with belch provocation and a...

BACKGROUND Enteric neurons undergo to functional changes during aging. We investigated the possible age-associated differences in enteric γ-aminobutyric acid (GABA)ergic transmission evaluating function and distribution of GABAergic receptors in human colon. METHODS Mechanical responses to GABA and GABA receptor agonists on slow phasic contractions were examined in vitro as changes in isometric tension in colonic muscle strips from young ( 65 years old). GABAergic receptor expression was assesse...

BACKGROUND Abdominal bloating is common in functional gastrointestinal disorders (FGID). To better characterize this patient population, we evaluated clinical and psychological characteristics of bloating and analyzed their differences by bloating severity. METHODS Patients with FGIDs evaluated at a single academic outpatient referral gastroenterology clinic were surveyed. Bloating severity was classified as minimal, moderate or severe. Symptom-specific questionnaires were used to evaluate bowel...

BACKGROUND Rectal hyposensitivity (RH) is a well-known pathophysiological dysfunction in chronic constipation. Whether biofeedback training improves RH and restores bowel function is unknown. AIM To investigate the efficacy of barostat-assisted sensory training (BAST) with syringe-assisted sensory training (SAST) in patients with RH in a randomized controlled trial. METHODS Patients with RH and chronic constipation (Rome III) were randomized to receive 6 biweekly sessions of BAST or SAST. Verbal...

BACKGROUND High-resolution manometry overcomes limitations imposed by axial and radial asymmetry as well as swallow and respiration-induced movement of the upper esophageal sphincter (UES), allowing for its reliable use in evaluation of dysphagic and reflux patients. The aim of this study was to determine normative values and their variability across position, sex, age, height, weight, BMI, and volume for clinically relevant deglutitive and non-deglutitive UES parameters. METHODS We studied 89 a...

BACKGROUND Pediatric cyclic vomiting syndrome (CVS) is a little-known clinical condition, frequently diagnosed with delay. This study aims to describe the clinical presentation and management and to define possible predictive factors of the disease outcome. METHODS In this retrospective study, all children who were diagnosed with CVS during the period 2010-2019 in three tertiary academic centers were included. The association between clinical variables and outcomes was investigated. KEY RESULTS ...

BACKGROUND Short-term trials demonstrate the low FODMAP diet improves symptoms of irritable bowel syndrome (IBS) but impacts nutrient intake and the gastrointestinal microbiota. The aim of this study was to investigate clinical symptoms, nutrient intake, and microbiota of patients with IBS 12 months after starting a low FODMAP diet. METHODS Participants enrolled in a previous short-term clinical trial and who had been through structured FODMAP restriction, reintroduction, and personalization wer...

BACKGROUND Several cross-sectional studies have reported an association between childhood constipation and exposure to stressful events. We planned to systematically review the literature on constipation and its associated stressful events. METHODS PubMed, Embase, and PsycINFO databases were searched (until February 2021) using standard search terms related to "constipation" and "stress" from 0 to 18 years that describe the association between psychological stressors and constipation. Studies we...

BACKGROUND Gastroparesis is a severe diabetes complication characterized by delayed gastric emptying. We examined patients with symptoms of diabetic gastroparesis using gastric emptying scintigraphy and ultrasound drink test. The primary aim was to investigate how ultrasound could provide information about gastric motility features in diabetic gastroparesis. MATERIAL AND METHODS We prospectively included 58 patients with diabetes (48 type 1) with symptoms of gastroparesis and 30 healthy controls...
