HISTORY.—On this subject there is little of importance in medical annals previous to the observations of Frederick Hoffmann,15 and little of importance subsequently save the observations of Mondière,16 though numerous personal observations are on record, as well as a number of excellent compilations in various monographs, text-books, encyclopædias, and dictionaries.

ETIOLOGY.—Spasmodic stricture of the oesophagus is a neurosis often hysterical. It is much more frequent in females than in males, and, although observed in young subjects and less frequently in old ones, is most common between the ages of twenty and fifty. It is sometimes observed in several members of a neurotic family. It is often associated with other evidences of neurosis, but sometimes constitutes the sole manifestation. Sometimes the cause defies detection. Sometimes it can be traced to a fear of strangulation, induced primarily by some accidental impediment to deglutition or the entrance of a foreign body. Strong mental emotion, such as the dread of hydrophobia after having been bitten by a dog, sometimes produces the affection.
It occurs in connection with organic lesions of the oesophagus, organic lesions of the stomach, organic lesions of the larynx and trachea, and organic lesions of the lungs, heart, large blood-vessels, and perioesophageal tissues, but likewise as a reflex disorder, with lesions of distant organs, as the genito-urinary tract, the intestines, the brain and spinal cord. Even pregnancy may produce reflex oesophagismus. It sometimes occurs as a direct or reflex manifestation of gout and of rheumatism. In a few instances it occurs as one of the manifestations of tetanus and of hydrophobia.
SYMPTOMATOLOGY, COURSE, DURATION, ETC.—The spasm may affect the oesophagus only, or may be associated with spasm of the muscles of the pharynx. It is usually manifested in a sudden inability to swallow or to complete the acts of deglutition. This may be transitory or may continue for a number of hours. The relaxation of the spasm is sometimes followed by the discharge of flatus and the copious secretion of pale urine. The spasm may recur at irregular intervals or be more or less distinctly intermittent. Sometimes it precedes every effort at deglutition. In some instances it occurs only upon attempts to swallow certain kinds of food, and the articles of food vary with different patients. Cold viands sometimes produce spasm when warm and hot food is tolerated. Consciousness of a liability to spasm increases the dysphagia for the time being, or brings it on suddenly when this liability had been forgotten. The spasm is sometimes painless and sometimes painful. In some instances it is associated with partial regurgitation of a mass of air (the globus hystericus).
The dysphagia is rarely complete, instances in which no liquids can be swallowed being infrequent. The aliment swallowed usually passes on into the stomach, upon relaxation of the spasm, after a certain period of detention varying from a number of seconds to many minutes. In cases of prolonged or persistent spasm the aliment is usually rejected, either at once or after a time, according as the contraction takes place at the pharyngeal extremity of the oesophagus or lower down. When rejected after some detention in the gullet, the aliments are usually enveloped with mucus or followed by expulsion of mucus and of flatus.
In some subjects the pain in swallowing is severe. Sometimes it is associated with spasm of the diaphragm (hiccough), spasm of the air-passages, palpitation of the heart, and syncope.
The liability to spasm sometimes continues for years. Sometimes it ceases permanently as suddenly and as unexpectedly as it began.
The seat of the spasm is referred by the patient to different regions, which in their totality comprise the entire extent of the oesophagus. In some patients the seat varies on different occasions. The actual seat of any individual spasm is best determined by exploration with the oesophageal bougie or by auscultating the oesophagus during the passage of a bolus. It is most frequent perhaps at the upper extremity, and then perhaps at the cardiac extremity. When habitually low down, there is some liability to permanent distension of the oesophagus from repeated retentions of food at the same place for hours together. In some instances food is regurgitated from the oesophagus after its retention for a day or even longer. When the spasm is high up, the regurgitation may follow the act of deglutition almost immediately.
