Weak and absent peristalsis [PDF]
Neurogastroenterology and Motility, 2012 AbstractBackground Weak and absent esophageal peristalsis are frequently encountered esophageal motility disorders, which may be associated with dysphagia and which may contribute to gastroesophageal reflux disease. Recently, rapid developments in the diagnostic armamentarium have taken place, in particular, in high‐resolution manometry with or ...

Inhibitory Effect of Lidocaine on Duodenal Peristalsis During Endoscopic Retrograde Cholangiopancreatography: A Multicenter, Randomized Controlled Trial (With Video) [PDF]
DEN OpenObjectives Conventional antispasmodics used during endoscopic retrograde cholangiopancreatography (ERCP), such as hyoscine butylbromide and glucagon, are often contraindicated in elderly patients with comorbidities.

Analytical Solution of Electro-Osmotic Peristalsis of Fractional Jeffreys Fluid in a Micro-Channel
Micromachines, 2017 The electro-osmotic peristaltic flow of a viscoelastic fluid through a cylindrical micro-channel is studied in this paper. The fractional Jeffreys constitutive model, including the relaxation time and retardation time, is utilized to describe the ...

Uremic Paralytic Ileus in a 70 Years Old Female: A Diagnostic Dilemma [PDF]
Clinical Case ReportsUremia has been associated with slowed intestinal motility, resulting in loss of peristalsis and the development of paralytic ileus. We present a case of uremia‐induced paralytic ileus in a 70‐year‐old woman. The patient was admitted with a 7‐day history

Esophageal acid burden in reflux patients with normal endoscopy: Does esophageal peristalsis matter?
Journal of the Formosan Medical Association, 2022 Background: A majority of patients with gastroesophageal reflux disease (GERD) have normal endoscopy. We aimed to investigate whether esophageal primary and secondary peristalsis influence esophageal reflux parameters in patients with normal endoscopy ...

Peristalsis by pulses of activity [PDF]
Physical Review E, 2021 Peristalsis by actively generated waves of muscle contraction is one of the most fundamental ways of producing motion in living systems. We show that peristalsis can be modeled by a train of rectangular-shaped solitary waves of localized activity propagating through otherwise passive matter.

Differences in the Control of Secondary Peristalsis in the Human Esophagus: Influence of the 5-HT4 Receptor versus the TRPV1 Receptor. [PDF]
PLoS ONE, 2016 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.
