Determinants of upper esophageal sphincter pressure in dogs

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1990
Chronic experiments were done on six dogs fitted with EMG electrodes on pharyngeal and esophageal musculature. Electromyographic activity of the cricopharyngeus was recorded in awake and sedated animals with and without manometric recordings as well as during esophageal distension.

Neuromuscular Organization of the Human Upper Esophageal Sphincter

Annals of Otology, Rhinology and Laryngology, 1998
The upper esophageal sphincter (UES) is a key component of swallowing, and yet, its anatomy and function are still incompletely understood. The UES is a functional entity that is composed of three muscles: the cricopharyngeal (CP) muscle, the inferior pharyngeal constrictor (IPC) muscle, and the upper esophageal (UE) muscle.

Esophageal stents for malignant strictures close to the upper esophageal sphincter

Gastrointestinal Endoscopy, 2007
Self-expanding stents are a well-accepted palliative treatment modality for strictures resulting from esophageal carcinoma. However, the use of stents close to the upper esophageal sphincter (UES) is considered to be limited by patient intolerance caused by pain and globus sensation and an increased risk of complications, particularly tracheoesophageal

Chalasia of the Upper Esophageal Sphincter

Acta Radiologica. Diagnosis, 1985
Four patients with absence of stable tonus (chalasia) of the pharyngo-esophageal segment, i.e., the cricopharyngeal muscle and the adjacent cervical esophagus, are reported. The tonus between swallows was completely absent in 2 patients and was seriously impaired in 2.

An overview of the upper esophageal sphincter

Current Gastroenterology Reports, 2000
The anatomy and physiology of the upper esophageal sphincter (UES) are complex. Much progress has been made over the past few years in our understanding this important sphincter. The closing muscles of the UES include the inferior pharyngeal sphincter, the cricopharyngeus (CP), and the cervical esophagus. The CP is composed of two parts, which may have

Manometric Studies of the Upper Esophageal Sphincter

Annals of Otology, Rhinology & Laryngology, 1977
The pharyngoesophageal sphincter (PES) has been studied extensively using the standard three lumen esophageal catheter. Studies using this catheter are nonreproduciible because intraluminal pressure in the PES is dependent on the orientation of the catheter. This difficulty was overcome when a multiluminal catheter was developed by Winans. In this work

Anatomy and Physiology of the Upper Esophageal Sphincter

The American Journal of Medicine, 1997
The upper esophageal sphincter (UES) is composed of the cricopharyngeus (CP), thyropharyngeus (TP; inferior pharyngeal constrictor [IPC] in humans), and cranial cervical esophagus. All 3 muscles may at times function to maintain tone in the UES, but only the CP contracts and relaxes in all physiologic states consistent with the UES.

The innervation of the human upper esophageal sphincter

Dysphagia, 1996
The neuroanatomy and physiology of the human upper esophageal sphincter (UES) has long been controversial. As a result, there has been little progress in diagnosing and treating dysphagias involving this area. In this study, three specimens of the UES obtained from human autopsies were examined by Sihler's stain.

Manometric Findings of the Upper Esophageal Sphincter in Esophageal Achalasia

World Journal of Surgery, 1998
AbstractPharyngeal and upper esophageal sphincter (UES) manometry was performed in 15 patients with esophageal achalasia and compared with that in 10 healthy controls. Neither the pharyngeal contraction pressure nor the UES resting pressure were significantly different between the two groups, although the UES residual pressure in patients with ...
