Part 66

DEFINITION.--Circumscribed destruction of portions of the mucous membrane of the oesophagus, the result of inflammatory processes.

ETIOLOGY.--Ulceration of the oesophagus occurs as a result of inflammation of the organ, as discussed in connection with Oesophagitis, and the cause varies with the character of the oesophagitis, whether idiopathic, traumatic, or symptomatic of disease elsewhere. Diseases, constitutional or local, provocative of ulceration of the oesophagus, usually implicate some portion of either the alimentary or the respiratory tract.

SYMPTOMATOLOGY.--The symptoms are in the main those described under Acute Oesophagitis, particularly the expulsion of sanguinolent products or of unmixed blood. Perforation into the trachea is indicated by expectoration of food or drink; perforation into the great vessels, by hæmatemesis, usually fatal; and perforation into the mediastinum, by emphysema and purulent cellulitis. When large or extensive ulcerations have cicatrized they occasion symptoms of organic stricture.

PATHOLOGY AND MORBID ANATOMY.--Referring to the corresponding section under Oesophagitis, attention may be directed here to the liability of deep-seated ulcers of the oesophagus to perforate the gullet and establish fistulæ with the trachea, bronchi, mediastinum, aorta, and carotid artery, according to the locality of the lesion. These lesions are usually necessarily fatal.

DIAGNOSIS.--The presence of blood in matters regurgitated or vomited forms the chief diagnostic indication of ulceration of the oesophagus, taken in connection with the usual symptoms of acute or chronic oesophagitis.

PROGNOSIS.--The prognosis is altogether dependent on the nature of the disease which has given rise to the ulceration.

TREATMENT.--The constitutional treatment will depend on the nature of the disease which has occasioned ulceration. Ergot and turpentine are administered in case of hemorrhage--the former best, perhaps, hypodermatically. Attempts are sometimes made to cauterize the ulcer or ulcers with nitrate-of-silver stick conveyed in a covered slotted canula, to be exposed when the fenestrum reaches the ulcerated locality, previously {419} determined by catheterization, or inferred to be reached by the sensations of the patient. The practice is uncertain in its manipulation and questionable in its results.

Stricture of the Oesophagus.

DEFINITION.--A constriction of the calibre of the oesophagus, whether spasmodic or organic in character. This definition excludes stenosis due to pressure from without.

Spasmodic Stricture of the Oesophagus.

DEFINITION.--A contraction of the muscles of the oesophagus, of variable duration, causing partial or complete stenosis of the gullet and interfering with the passage of food or of food and drink to the stomach.

SYNONYMS.--Oesophagismus, Spasm of the oesophagus, Cramp of the oesophagus, Convulsive dysphagia, Spasmodic dysphagia, Spasmodic stenosis of the oesophagus, Spastic stricture of the oesophagus.

HISTORY.--On this subject there is little of importance in medical annals previous to the observations of Frederick Hoffmann, and little of importance subsequently save the observations of Mondière, 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 {420} 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.

PATHOLOGY AND MORBID ANATOMY.--The affection being usually a pure neurosis, there is no oesophageal lesion to be cited. In some of the few autopsies recorded, constriction has been noted without lesion of tissue.

DIAGNOSIS.--The diagnosis is based on the sudden onset of the spasm without assignable cause, its intermittent or recurrent character, its manifestation in advance of the effort at deglutition, the symptoms of regurgitation, the coexistence of some of the affections mentioned in connection with its etiology, and on the satisfactory result of exploration with the oesophageal bougie; which differentiates the affection from organic stricture or mechanical obstruction. In catheterization of the oesophagus {421} in cases of pure spasm, although the sound is usually arrested at the seat of constriction, it passes onward after a few moments by sudden relaxation of the spasm. Sometimes, indeed, the very first manipulation of this kind overcomes the spasm permanently.

In the absence of other indications the differentiation from spasm of organic origin rests, in great measure, on the conservation of nutrition, cases being few in which the spasm is persistent enough to interfere so materially with the ingestion of aliment as to produce emaciation.

PROGNOSIS.--The prognosis is usually favorable in spasm of the oesophagus, except in cases where the underlying malady is itself a grave one. Patients do not die of neurotic spasm of the oesophagus. In the majority of cases it is susceptible of cure within a few weeks, sometimes much more promptly. Even when it continues for months or for years there is little fear of permanent injury to the general health, inasmuch as sufficient nutriment of some kind or other can be ingested to sustain the patient.

The duration of the affection depends upon the surroundings of the patient, his amenability to treatment, and the existence or absence of disease in the oesophagus or elsewhere. In cases dependent upon diseased conditions in the oesophagus or elsewhere the character of the disease controls the prognosis, both immediate and ultimate. Thus, aneurism of the aorta, tuberculosis, ulceration of the larynx and trachea, carcinoma of the stomach, tetanus, and hydrophobia present the highest unfavorable indications. Purely neurotic cases are extremely prone to recurrence.

TREATMENT.--The treatment to be pursued will depend upon the nature of the case. If due to organic lesion in the oesophagus or in some other organ, the treatment will be directed to that affection, whatever it may be. If due to emotional disturbance, therapeutic efforts will be directed to their suppression or removal. If purely hysterical, appropriate constitutional remedies for that condition will be prescribed. These comprise asafoetida, valerian, camphor, musk, oxide of zinc, bromides, belladonna, conium, and so on, best administered in small doses at frequent intervals.

Local treatment is almost always necessary, both for its beneficial mechanical effects and for its emotional influence. This consists in the systematic passage of the bougie; and it is by far the best practice to insist upon the patient's submission to it without an anæsthetic. In cases of intense hyperæsthesia, which are rare, and in the initial exploratory passage of the instrument in highly excitable or uncontrollable subjects, anæsthesia may be resorted to if there be no contraindication. The mere passage of the bougie will often effect immediate relaxation of the spasm. When required, the manipulation may be repeated a few times at intervals of several days. Should the passage of the bougie determine the stricture to be purely spasmodic, the patient should be made to partake of food in the physician's presence at first, and afterward under the supervision of an efficient attendant, until it becomes evident that there is no absolute impediment to the passage of food. The presence of the physician during early attempts at taking ordinary food imparts such confidence in the patient that he soon overcomes his dread of strangling and learns to eat again as he should do. Meantime, it may be necessary from time to time to pass the bougie just before food is taken. {422} In such cases it is well to smear the instrument with ointment of belladonna, so as to deposit it more or less along the entire tract of the oesophagus. Failing by these methods, success may follow the occasional passage, at intervals of a few days, of a sponge probang saturated with a very weak solution of iodine or of silver nitrate.

Counter-irritation along the course of the pneumogastric nerve or along the spine is sometimes useful.
