Part 67

Electricity is sometimes employed to overcome the spasm; but intra-oesophageal electrization of every kind is risky from the danger of exciting fatal syncope from irritation of the pneumogastric nerve. This objection is not applicable to percutaneous electrization, save in a much more limited degree. Caution is requisite even with external manipulations along the tract of the pneumogastric nerve; and such manipulations, therefore, should not be undertaken without sufficient familiarity with the effects of electric currents in that situation.

Taken all in all, the best results seem to follow the systematic use of the bougie and enforced deglutition under the eye of an attendant in whom the patient feels reliance can be placed in case the food should "go the wrong way" or become impacted in the gullet.

Organic Stricture of the Oesophagus.

DEFINITION.--Diminution in the calibre of the oesophagus in consequence of organic alterations in its walls, whether interstitial, cicatricial, or malignant.

SYNONYM.--Stenosis of the oesophagus.

HISTORY.--As mentioned in connection with other affections of the oesophagus, so with organic stricture: though much more has been written on the subject, it is to the observations and publications of Mondière, so frequently cited, that we must credit medical literature with a due appreciation of this topic. The last thirty years especially have been prolific in the record of cases, and their study has been further stimulated by the attention directed to the operation of gastrostomy as a means of prolonging life in cases otherwise hopelessly fatal.

ETIOLOGY.--Organic stricture of the oesophagus is occasionally congenital. As a rule, life is rarely prolonged under such conditions, but cases are on record in which it has been preserved to quite advanced age. Thus, in a female who died from inanition at fifty-nine years of age, after lifelong symptoms of stricture (Everard Homes), there was an annular stricture behind the first ring of the trachea; and in a male subject who died with pneumonia at seventy-four years of age, after lifelong symptoms of stricture, the stricture was found at the cardiac extremity of the oesophagus, which was enormously dilated its entire length above the constriction.

In the majority of cases the stricture is due to cicatricial obliteration of more or less of the calibre of the oesophagus, the result of losses of substance following scalds produced by caustic substances swallowed, mostly by accident and sometimes by design. Wounds of all kinds, {423} whether from the interior, as in the case of foreign bodies and instruments of extraction, or from the exterior, as in the case of surgical operations, wounds from firearms, and the like, are apt in their cicatrization to give rise to this form of stricture.

Though denied by some authorities, syphilitic disease of the oesophagus is an undoubted cause of stricture. Setting aside disputed records of older authorities, we may cite recent cases reported by Lancereaux, West, Wilks, Virchow, and Lublinski, the latter-named going deeply into the bibliography, pathology, and therapeutics of stricture from syphilis. The author could add his personal testimony were it requisite.

Stricture of the oesophagus is likewise occasioned by the presence of papillomatous, fibroid, and other morbid growths. Carcinoma is quite a frequent cause.

The frequent deglutition of undiluted spirituous liquors is said to give occasion at times to stricture of the oesophagus, but in these instances this result is usually due to precedent chronic oesophagitis thereby excited, and terminating in infiltration and hyperplasia of the submucous connective tissue, and sometimes great thickening of the epithelium as well.

Males are more frequently the subjects of stricture of the oesophagus, and early adult life the most frequent period for its occurrence, though it may present at any age.

SYMPTOMATOLOGY.--Except in traumatic cases, the earliest symptoms, preceded in some instances by indications of mild oesophagitis, perhaps unnoticed or unrecognized, are occasional impediments to deglutition of large and firm boluses, or rather a mechanical obstacle to completion of the act of glutition occurring at intervals of a few meals or a few days. After a while the swallowing of a large solid bolus becomes permanently impracticable. Then, sometimes, repeated efforts become necessary to swallow small masses of solid food; and even to do this may require external manipulation, or at least the additional pressure of liquids swallowed immediately after the solid bolus. These efforts are sometimes attended with spasm, regurgitation, and pain, and may be accompanied in addition with tracheal dyspnoea, and with nervousness in consequence. As the disease progresses it becomes impossible to swallow solid food, and subsequently even fluid food in extreme cases. The bolus is then often regurgitated immediately after its deglutition, and may be covered with mucus, blood, pus, or fragments or detritus of ulcerated malignant growth, according to the nature of the case. Pain and sensations of rawness are often felt at the point of constriction, whence the pain often radiates toward one or both scapulæ. If the tube is much dilated above the stricture, the food may be detained in the sac for several hours, and then be regurgitated in a softened, partially-decomposed condition. Should the mass be so situated as to compress the trachea, suffocative symptoms may be produced.

In stricture due to organic disease there may be dysphonia from pressure or injury to the recurrent laryngeal nerve producing paralysis of the vocal band. The anatomical relations of the left recurrent nerve renders it the much more liable of the two to become implicated. Moderate dyspnoea may result from this paralysis by reason of the reduced space of the glottis.

{424} PATHOLOGY AND MORBID ANATOMY.--Organic stricture of the oesophagus is usually due to disease or structural change involving the mucous membrane and submucous connective tissue; but the muscular structure may become involved likewise. It may, however, be due to abnormal laxity of the mucous membrane, permitting a fold to occupy a position impeding the passage of the bolus.

In cases which are not carcinomatous the diminution in the actual calibre of the tube is usually due to submucous proliferation of connective tissue and to thickening of the mucous membrane. The encroachment on the calibre of the tube may be quite slight, or may be so great as to amount to almost complete occlusion.

The seat of stricture is at the upper portion of the oesophagus most frequently, then at the cardiac extremity, at the point of crossing by the left bronchus, and at the point of passage through the diaphragm--all localities slightly constricted normally--but it may occur at any portion.

In most instances the stricture is single. There may, however, be two, three, or even four strictures. Multiple strictures are most common after deglutition of caustic substances which have made their way clear down into the stomach.

Syphilitic strictures are usually single, and so, as a rule, are strictures of malignant origin. The latter are much larger in extent.

Cicatricial strictures from caustic substances may be in the form of bands, rings, or longitudinal stripes or folds. Sometimes they are quite extensive, and have been known to interest fully one-third of the length of the oesophagus. The circumference, length, calibre, and thickness of the stricture, however, vary within the most extreme limits. Occasionally occlusion of the tube is complete.

The detention of food above the stricture usually dilates the oesophagus, producing hypertrophy of the mucous membrane and submucous connective tissue, followed in its turn by fatty degeneration. Atrophy of the oesophagus may ensue below the stricture if at all tight, and the mucous membrane becomes thrown into longitudinal folds.

DIAGNOSIS.--The diagnosis of organic stricture of the oesophagus rarely presents difficulty. Dysphagia, spasm, and regurgitation are quite characteristic of stricture. When the constriction is high up, the vomiting or regurgitation of food may closely follow its deglutition; when low down, this act may be delayed ten or fifteen minutes, in some cases for hours. Alkaline reaction of the vomited matters is indicative of their having failed to reach the stomach. The presence of blood-cells, pus-cells, and cancer-cells indicates ulceration, suppuration, and malignant disease, respectively.

Auscultation of the oesophagus during deglutition of water will indicate the seat of stricture by revealing the ascent of consecutive air-bubbles even when palpation with bougies fails. The passage of oesophageal bougies or the stomach-tube into the oesophagus will often reveal the point of stricture. Its length is estimated by the distance of the resistance offered to the passage of the instrument; its diameter, by the size of the largest instrument which can be passed through it; and its consistence, by the character of the resistance. Care is requisite in manipulating with these instruments, lest by undue exertion of force they be passed through an ulcerated portion of the wall of the tube or {425} a diverticulum. The character of the resistance is sometimes the sole means of differentiating stricture from stenosis due to compression of the oesophageal wall from its outside.

It sometimes happens, in individuals with impaired sensitiveness of the epiglottis or vestibule of the larynx, that the exploratory bougie is introduced into the air-passage instead of the gullet. The usual premonitory phenomena of suffocation will indicate the mistake. There is some likelihood, too, of entering the larynx in individuals with unusually prominent cervical vertebræ and in cases of stricture at the extreme upper portion of the oesophagus. In introducing these instruments into the oesophagus, therefore, it is well that they be guided along the fore finger of the disengaged hand, and passed deeply into the throat, either to the side of the larynx or behind it. By keeping to the side and reaching the oesophagus by way of the laryngo-pharyngeal sinus the risk of entering the larynx may be avoided. Before introducing the tube the case should be carefully examined for aneurism, which by pressure sometimes gives rise to the ordinary subjective symptoms of stricture. Should aneurism be detected, passage of the tube would be hazardous.

PROGNOSIS.--The prognosis is in most instances unfavorable. It is comparatively favorable in cases of moderate stricture due to causes apparently remediable. The extent and volume of the stricture progress more or less slowly according to the nature of its cause, and in non-malignant cases, such as are due to the action of caustic substances, it may last for years before the patient, if not relieved, succumbs, as he does, from gradual inanition. In the earlier stages, before the hypertrophied muscles above the stricture undergo fatty metamorphosis, the increased muscular power is sufficient to force nourishment through the stricture; but when this becomes no longer possible progressive marasmus must ensue. Meantime, abscess may become developed in consequence of the pressure of retained food, and tuberculous degeneration of the lung and local gangrene may take place in consequence of the malnutrition.

TREATMENT.--The treatment of organic stricture of the oesophagus resolves itself into maintenance of the general health, the administration of the iodides to promote absorption of effusions into the connective tissue or the muscles, mechanical and operative measures for removal of the causes of the constriction or the strictured tissues themselves, and operations for securing artificial openings below the point of stricture for the introduction of nourishment (oesophagostomy and gastrostomy). Nourishment by enema is of great value.

In carcinomatous stricture local measures are in the main unjustifiable, as they usually entail injury which may prove very serious. Arsenic internally is thought to retard the progress of malignant disease when administered early and persistently. Morphine is used hypodermically to assuage pain.

In cancerous and tuberculous disease great caution is requisite in determining upon mechanical or surgical procedures. In cicatricial stenosis from the effects of caustic substances, such measures may be undertaken with much less consideration.
