Transient inflammation is known to alter visceral sensory function and frequently precede the onset of symptoms in a subgroup of patients with irritable bowel syndrome (IBS). Duration and severity of the initial inflammatory stimulus appear to be risk factors for the manifestation of symptoms. Therefore, we aimed to characterize dose-dependent effects of(More)
The current gold standard for the surveillance of Barrett’s esophagus is the Seattle four-quadrant biopsies protocol (4-QB). Using endoscopic brush cytology, this study prospectively investigated whether digital image cytometry (DICM) is of additional benefit over regular histology as a predictor for progression to high-grade dysplasia or cancer during a(More)
OBJECTIVES To assess magnetic resonance (MR)-colonography (MRC) for detection of colorectal lesions using two different T1w three-dimensional (3D)-gradient-recalled echo (GRE)-sequences and integrated parallel data acquisition (iPAT) at a 3.0 Tesla MR-unit. MATERIALS AND METHODS In this prospective study, 34 symptomatic patients underwent dark lumen MRC(More)
This study aimed to characterize the role of the neuropeptide calcitonin gene-related peptide (CGRP) in the development of mechanically induced visceral hyperalgesia. Tonic colorectal distension (CRD) was performed in fasted, conscious male Sprague-Dawley rats. The visceromotor reflex associated with noxious CRD was determined as the number of contractions(More)
BACKGROUND AND STUDY AIMS The reference surveillance method in patients with Barrett's esophagus is careful endoscopic observation, with targeted as well as random four-quadrant biopsies. Autofluorescence endoscopy (AFE) may make it easier to locate neoplasia. The aim of this study was to elucidate the diagnostic accuracy of surveillance with AFE-guided(More)
AIM To compare the efficacy of simethicone with placebo and the prokinetic cisapride in patients with functional dyspepsia. METHODS One hundred and eighty-five patients with functional dyspepsia were randomized and treated in a double-dummy technique with simethicone (105 mg t.d.s.), cisapride (10 mg t.d.s.) or placebo (t.d.s.). The primary outcome(More)
Gastric distension has been used to evaluate gastric sensory function in humans, but the methodology is poorly validated and studies in vivo comparing different distension protocols are lacking. We aimed to compare the influence of the mode of gastric distension on sensation and gastric compliance utilizing a barostat device. In seven healthy volunteers, we(More)
Functional gastrointestinal disorders (FGD) are highly prevalent worldwide. Recent research demonstrates that complex and interacting biological and behavioral mechanisms contribute particularly to the pathogenesis of irritable bowel syndrome and functional dyspepsia. Dysregulation of the enteral, neuroenteric, visceral-autonomic, and central nervous(More)
BACKGROUND The high prevalence of functional bowel disorders among the general population contrasts with the limited number of pharmacological treatment options for this condition. This has led to an interest for alternative therapeutic approaches. Padma Lax is an herbal laxative on the basis of Tibetan formulas. Our aim is to examine the effect of Padma(More)
Abdominal pain syndromes can be categorised into acute or chronic manifestations. In general, diagnostic work-up is targeted upon identification of structural lesions that cause the symptoms and allows therapeutic measures that permanently cure the cause of symptoms. If no structural or biochemical abnormality can be identified upon utilising the necessary(More)
