Large Amplitude, Short Wave Peristalsis
6 Valveless, tubular pumps are widespread in the animal kingdom, but the mechanism by which these pumps generate fluid flow are often in dispute. Where the pumping mechanism of many organs was once described as peristalsis, other mechanisms, such as dynamic suction pumping, have been suggested as possible alternative mechanisms. Peristalsis is often evaluated using criteria established in a tec...
متن کاملDisruption of primary and secondary esophageal peristalsis by afferent stimulation.
Recent studies have shown that afferent signals originating from the pharynx inhibit progression of primary esophageal peristalsis. Our aim was to further elucidate the effect of esophageal and pharyngeal afferent stimulation on primary and secondary esophageal peristalsis. We studied the effect of esophageal air distension and pharyngeal water stimulation on progression of primary and secondar...
متن کاملEffects of large hiatal hernias on esophageal peristalsis.
HYPOTHESIS Anatomic changes induced by large hiatal hernia may alter esophageal pressure topography measurements made during high-resolution manometry. DESIGN Retrospective study. SETTING Single-institution tertiary hospital. PATIENTS Ninety patients with large (>5 cm) hiatal hernias on endoscopy were compared with a control group of 46 patients without hernia selected from the same datab...
متن کامل'Efficacy' of esophageal peristalsis: a manometric parameter to quantify esophageal body dysfunction.
Esophageal motor abnormalities are currently categorized into separate entities based on standard manometry. The clinical significance of these categories is controversial. We evaluated whether ambulatory 24-h esophageal motility monitoring improves the assessment of patients thought to have a primary esophageal motor disorder. Standard and ambulatory 24-h esophageal motility records of 30 heal...
متن کاملDifferences in the Control of Secondary Peristalsis in the Human Esophagus: Influence of the 5-HT4 Receptor versus the TRPV1 Receptor
OBJECTIVE Acute administration of 5-hydroxytryptamine4 (5-HT4) receptor agonist, mosapride or esophageal infusion of the transient receptor potential vanilloid receptor-1 (TRPV1) agonist capsaicin promotes secondary peristalsis. We aimed to investigate whether acute esophageal instillation of capsaicin-containing red pepper sauce or administration of mosapride has different effects on the physi...
