Esophageal motility: effects of injection sclerotherapy. 1984

G M Larson, and D J Vandertoll, and D T Netscher, and H C Polk

The purpose of this project was to evaluate the acute and chronic effects of sclerotherapy on esophageal motility and function. We studied motility in eight patients before and after injection sclerotherapy of esophageal varices. We injected the varices with 5% sodium morrhuate twice during the first week and then at 1, 2, 3, and 6 months. Lower esophageal sphincter pressure, contraction wave amplitude, and duration were not altered by sclerotherapy. However, the length of the high-pressure zone increased significantly from 3.6 +/- 0.3 cm to 4.2 +/- 0.2 cm during the first 3 days after initial treatment, and sclerotherapy caused considerable distortion of peristaltic wave form. Also, esophageal peristaltic velocity decreased in three patients who complained of dysphagia and subsequently developed esophageal stricture. The strictures have responded well to dilatation, and in two patients velocity has even returned toward the baseline value. Reflux esophagitis has not been a problem. Esophageal motility is altered by sclerotherapy of esophageal varices. Stricture formation seems to be reversible after sclerotherapy is stopped or discontinued.

D007267	Injections	Introduction of substances into the body using a needle and syringe.	Injectables,Injectable,Injection

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements
D010528	Peristalsis	A movement, caused by sequential muscle contraction, that pushes the contents of the intestines or other tubular organs in one direction.	Peristalses
D011312	Pressure	A type of stress exerted uniformly in all directions. Its measure is the force exerted per unit area. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)	Pressures
D004932	Esophageal and Gastric Varices	Dilated blood vessels in the ESOPHAGUS or GASTRIC FUNDUS that shunt blood from the portal circulation (PORTAL SYSTEM) to the systemic venous circulation. Often they are observed in individuals with portal hypertension (HYPERTENSION, PORTAL).
