BACKGROUND The absence of high-resolution esophageal manometry (HREM) norms in pediatrics limits the assessment of children with dysphagia. This study aimed to describe HREM parameters in a cohort of children without dysphagia. METHODS Children ages 9-16 years with a negative Mayo Dysphagia Questionnaire screen and normal histologic findings underwent HREM after completion of esophagogastroduodenoscopy. Ten swallows of 5 ml 0.45% saline boluses per subject were captured in supine position. Analy...

BACKGROUND Transcranial alternating current stimulation (tACS) and transcranial random noise stimulation (tRNS) have been shown to have physiological and functional effects on brain excitability and motor behavior. Yet, little is known about their effects in the swallowing system. AIM To examine the effects and optimal stimulation parameters of tACS and tRNS for modulating excitability of human pharyngeal motor cortex. METHODS 10 Hz (alpha), 20 Hz (beta), 70 Hz (gamma) tACS, 0.1-640 Hz (full-spe...
BACKGROUND The colonic motor patterns associated with gas transit are poorly understood. This study describes the application of high-resolution impedance manometry (HRiM) in the human colon in vivo to characterize distal colonic motility and gas transit; (a) after a meal and (b) after intraluminal gas insufflation into the sigmoid colon. METHODS HRiM recordings were performed in 19 healthy volunteers, with sensors positioned from the distal descending colon to the proximal rectum. Protocol 1 (n...

BACKGROUND Gastrointestinal infections represent a risk factor for functional gastrointestinal and somatoform extraintestinal disorders. We investigated the prevalence and relative risk (RR) of gastrointestinal and somatoform symptoms 5 months after SARS-CoV-2 infection compared with a control cohort. METHODS One hundred and sixty-four SARS-CoV-2 infected patients and 183 controls responded to an online questionnaire about symptoms and signs during the acute phase of the infection and after 4.8 ...

Dysphagia lusoria is a rare cause of dysphagia due to impingement of the esophagus by an aberrant right subclavian artery. Although most remain asymptomatic, this aberrant vessel can lead to progressive dysphagia in childhood or even later in life as a result of arteriosclerotic burden and attenuation of esophageal compliance that led to esophageal compression. We present a 56-year-old man with a 3-year history of progressively worsening dysphagia to solids and liquids and globus sensation. Vide...
BACKGROUND The low FODMAPs (fermentable oligo-, di-, monosaccharides, and polyols) diet improves lower gastrointestinal symptoms. Patients suffering from proton pump inhibitor (PPI) refractory gastroesophageal reflux disease (GERD) have limited treatment options. We investigated the efficacy of a low FODMAPs diet in patients with PPI refractory GERD. METHODS This multicenter, randomized, open-label study compared the efficacy of a 4-week low FODMAPs diet and usual dietary advice (ie, low-fat die...
BACKGROUND Tapentadol is a combined opioid agonist and norepinephrine reuptake inhibitor with fewer gastrointestinal side effects at equianalgesic doses compared with classical strong opioids. Previous studies on tapentadol have included multi-morbid patients in whom confounders exclude detailed assessment of the mechanistic effects and strict comparison with other opioids or placebo. This study aimed at investigating the effects of tapentadol and oxycodone on gastrointestinal motility and gastr...
BACKGROUND Esophageal chemical clearance has been evaluated with the post-reflux swallow-induced peristaltic wave (PSPW) index. The factors triggering PSPW in Gastro-esophageal reflux disease (GERD) have not yet been investigated. This multicenter study was aimed at evaluating the characteristics of reflux episodes associated with PSPW occurrence in patients with typical GERD symptoms. METHODS Impedance-pH tracings from patients with typical reflux symptoms were analyzed. Sixteen healthy subject...

BACKGROUND Biofeedback therapy is useful for treatment of fecal incontinence (FI), but is not widely available and labor intensive. We investigated if home biofeedback therapy (HBT) is non-inferior to office biofeedback therapy (OBT). METHODS Patients with FI (≥1 episode/week) were randomized to HBT or OBT for 6 weeks. HBT was performed daily using novel device that provided resistance training and electrical stimulation with voice-guided instructions. OBT consisted of six weekly sessions. Both ...
