Chronic Oesophagitis

DEFINITION.—A chronic inflammation of some of the tissues of the oesophagus.

SYNONYM.—Oesophagitis chronica.

ETIOLOGY.—Chronic oesophagitis is sometimes a sequel of the acute affection. More frequently it is the result of excessive use of strong alcoholic beverages or of very hot drinks. It is said to be sometimes the result of passive congestion in chronic pulmonary and cardiac diseases. It follows the prolonged sojourn of foreign bodies in the oesophagus. It exists in connection with carcinoma of the oesophagus, with dilatation, and with stricture of the oesophagus, and with other diseases obstructing the tube externally or internally. It is sometimes produced by caries of the vertebræ, both scrofulous and syphilitic, and by the pressure of aneurismal and other tumors.

PATHOLOGY AND MORBID ANATOMY.—Hypertrophy of the mucous membrane of the oesophagus, of the submucous connective tissue, and even of the muscular coat, are the processes which take place in chronic oesophagitis, especially when it has been of long continuance. This hypertrophy, when at or near the cardiac extremity, may produce stricture (Rokitansky and others), with subsequent dilatation of the oesophagus from its frequent and prolonged distension by food which should have passed on at once into the stomach.

On post-mortem examination the main evidences of disease are most frequent in the lower third of the organ. Its folds of mucous membrane are thick and prominent, dirty red, brownish-red, or gray, as may be, abraded here and there, and covered with viscid muco-purulent secretions. Abscesses and ulceration are not uncommon in cases due to prolonged pressure or extension of disease from outside the tube. Such ulceration has not uncommonly been the source of serious hemorrhage.

Diffuse inflammation of the peri- or retro-oesophageal connective tissue has been noted as an occasional sequel to the inflammatory process in the walls of the oesophagus.

SYMPTOMATOLOGY, ETC.—The symptoms of simple chronic oesophagitis are similar in the main to those of mild acute oesophagitis, but are often still more moderate, and therefore likely to be overlooked. In severe cases the symptoms are chiefly those of the disease, usually stenotic, which has excited the chronic inflammatory process. The course is prolonged and the duration indefinite. Stricture is a frequent sequel.

DIAGNOSIS.—The diagnosis rests on the same principles and inferences as in acute oesophagitis, the symptoms, however, being of longer duration. The auscultatory signs of arrest or impediment in the descent of the solid or liquid bolus are usually more definite than in acute oesophagitis. The same differentiations are available in excluding spasm, stricture, and malignant diseases. The use of the sound or catheter is much more justifiable than in the acute variety.

PROGNOSIS.—The prognosis is usually unfavorable, on account of the great liability to stricture and occlusion from organization of inflammatory products.

TREATMENT.—Chronic oesophagitis may require both local and constitutional treatment. The constitutional treatment will have to be adapted to the cause of the disease. If due to obstructed circulation in consequence of valvular disease of the heart, digitalis and remedies of its class will be indicated. If due to obstructive pulmonic disease, chloride of ammonium and alkaline remedies will be indicated. Syphilitic inflammation requires the mixed treatment, with mercuric chloride and potassium iodide or their equivalent. Iodides, indeed, are often required in non-specific cases, and are useful particularly in ordinary circumscribed oesophagitis. Under all conditions alcoholic beverages should be interdicted, and so should the deglutition of all irritating food and drink. Mild, bland, and mucilaginous substances should be largely employed in food and drink. The copious use of carbonic-acid waters is also recommended (Oppolzer). Sinapisms and revulsives to the side of the cervical and dorsal vertebræ are also recommended by some writers (Oppolzer).

The topical treatment consists in the systematic use every few days of aqueous solutions of astringents (alum, tannin, ten to thirty grains to the ounce) or alterants (compound solution of iodine, twenty minims to the ounce) passed gently over the diseased surfaces by means of a piece of soft surgical sponge securely attached to a flexible staff.

Severe pain of rather sudden occurrence is usually attributable to circumscribed ulceration, and is best treated by superficial cauterization, as above, with a dilute solution of silver nitrate (ten grains to the ounce). These remedies may be used in the form of ointments of the same strength smeared upon a rather large flexible bougie. To relieve pain and sense of constriction belladonna or stramonium ointment, applied in the same manner, sometimes fulfils a useful indication. Before making these applications attempts should be made by auscultation to locate the seat of disease or obstruction. After subsidence of the disease, occasional catheterization may be practised at intervals of several weeks, in order to detect any recommencing stenosis.
