Human Esophagus

The opossum esophagus is commonly used as an animal model of the human esophagus. We used esophageal manometry in normal animals to provide basal data about normal esophageal motor functions in vivo in this species. At rest, separate and distinct high pressure zones can be recorded at the level of the lower esophageal sphincter, diaphragmatic hiatus, aortic arch, and upper esophageal sphincter. Each zone demonstrates a characteristic pattern of pressures in the radii of the coronal section and a characteristic response to swallowing. The hiatal and aortic zones can be mistaken for the esophageal sphincters. Pressures in the sphincters fall with swallowing. Peristalsis is not bolus-dependent and occurs with 98% of swallows. Pressures generated by peristalsis are greater in the middle of the esophagus than at the ends. Values for resting lower esophageal sphincter pressure and the characteristics of peristalsis were reproducible between different studies in the same animals.

Peristaltic Contractions

Studies were performed to investigate the effect of prostaglandin E2 on esophageal motility in 12 healthy volunteers. PGE2 infusion caused a dose-dependent reduction in the lower esophageal sphincter pressure. The threshold dose was less than 0.05 mug-kg-1-min-1 and maximal reduction of pressure (60%) occurred with a dose of 0.4 mug-kg-1-min-1. In contrast to its effect on the lower esophageal sphincter, PGE2 did not alter the pressure in the upper esophageal sphincter. PGE2 did not influence resting esophageal pressures; the amplitude of peristaltic contractions was reduced in the lower but not in the upper part of the body of the esophagus. These studies show that in man PGE2 exerts selective inhibitory influence on the activity of the lower part of the esophagus and lower esophageal sphincter which are composed of smooth muscle fibers.

Inclusion body myositis (IBM) is a progressive degenerative skeletal muscle disease leading to weakening and atrophy of both proximal and distal muscles. Dysphagia is reported in up to 86% of IBM patients. Surgical cricopharyngeal myotomy may be effective for cricopharyngeal dysphagia and there is one published report that botulinum toxin A, injected into the cricopharyngeus muscle using a hypopharyngoscope under general anesthesia, relieved IBM-associated dysphagia. This report presents the first documentation of botulinum toxin A injection into the upper esophageal sphincter using a flexible esophagogastroduodenoscope under conscious sedation, to reduce upper esophageal sphincter pressure and successfully alleviate oropharyngeal dysphagia in two IBM patients.
