Esophageal and upper esophageal sphincter motor function in babies

The American Journal of Medicine, 2001
The incidence of concomitant feeding and airway-related disorders is high among premature infants and babies with congenital anomalies. The cause of these disorders is commonly attributed to foregut dysfunction, and the approach to diagnosis and management is largely empiric.

Disorders of Upper Esophageal Sphincter Motility in Children

Journal of Pediatric Gastroenterology and Nutrition, 1987
SummaryDysfunction of the upper esophageal sphincter was found in five out of 44 children with gastroesophageal reflux. Three of the five children had mental retardation associated with Silver Russell syndrome. 5p syndrome, or minimal change myopathy. The five patients had swallowing disorders.

Upper Esophageal Sphincter in Health and Disease

Surgical Clinics of North America, 1971
Esophageal manometry has identified, as part of the complex act of swallowing, a sphincter-like high pressure zone corresponding to the cricopharyngeus muscle and adjacent pharyngeal and esophageal musculature. Functional abnormalities may occur under a variety of circumstances and lead to disabling symptoms which may be relieved by cricopharyngeal ...

Upper esophageal sphincter impedance as a marker of sphincter opening diameter

American Journal of Physiology-Gastrointestinal and Liver Physiology, 2012
The measurement of the physical extent of opening of the upper esophageal sphincter (UES) during bolus swallowing has to date relied on videofluoroscopy. Theoretically luminal impedance measured during bolus flow should be influenced by luminal diameter.

Upper esophageal sphincter function during belching

Gastroenterology, 1986
We studied the mechanism of belching with specific attention to the upper esophageal sphincter (UES) in 14 normal volunteers. Belching occurred by the following sequence of events: lower esophageal sphincter relaxation; gastroesophageal gas reflux, recorded manometrically as a gastroesophageal common cavity phenomenon; UES relaxation ...

Retrograde upper esophageal sphincter function… and dysfunction

Neurogastroenterology & Motility, 2022
AbstractUpper esophageal sphincter (UES) function has been extensively studied in the context of swallowing and antegrade bolus transit, but relatively little attention has been paid to its retrograde function to facilitate belching. Indeed, prior to 2019, there were only three case reports in the world literature of individuals with a physiologically ...

Functional anatomy and physiology of the upper esophageal sphincter

The American Journal of Medicine, 2000
Upper esophageal sphincter (UES) refers to the high-pressure zone located in between the pharynx and the cervical esophagus. The physiological role of this sphincter is to protect against reflux of food into the airways as well as prevent entry of air into the digestive tract.

Upper esophageal sphincter function during deglutition

Gastroenterology, 1988
Upper esophageal sphincter function was investigated during swallows of graded volumes in 8 normal volunteers. Concurrent recordings of video-fluoroscopic and manometric studies were obtained and correlated with each other by means of a videotimer. Maximal upper esophageal sphincter (UES) pressure was typically located 1.5 cm distal to the air-tissue ...

Pharyngeal and upper esophageal sphincter manometry in humans

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1990
Manometric studies of pharyngeal-upper esophageal sphincter (UES) coordination during swallowing have proven difficult. Asymmetry of the UES makes pressure measurements with a single, unoriented transducer suspect. Perfused systems lack the necessary response rate for measuring peak pharyngeal contraction pressures.

Hypertonic Upper Esophageal Sphincter in the Oculopharyngeal Syndrome

Journal of Clinical Gastroenterology, 1980
The oculopharyngeal syndrome (OPS) is a rare variant of muscular dystrophy characterized by progressive ptosis and dysphagia. Previous esophageal motility studies in OPS have yielded conflicting results because of low-fidelity esophageal recording systems.
