In sufferers from esophageal stricture of the neurotic type the muscles by an unfortunate perversion of nerve force contract in front of the bolus instead of behind it. This contraction may be so complete as to prevent even the swallowing of liquids. Usually, however, liquids can be swallowed without much difficulty. Such patients, then, if they become much run down in weight, must be fed on milk and eggs and ice cream and the gruels and soups until they gain in weight. While they are much under weight their condition is distinctly worse and their power of co-ordination much less. It is, however, not hard to make them gain in weight. This gain in weight acts as a strong suggestion which persuades them that they are getting better and this of itself soon helps them to control their muscles. Local treatment does harm rather than good. Ice in small pieces swallowed shortly before a meal seems in some patients to have the effect of making the muscles less prone to follow the inco-ordinate nervous action and thus renders swallowing much easier. In some, and especially in nervous people, warm liquids have the same effect, while ice produces further irritation. Acids nearly always increase the spasmodic condition. Sucking a piece of hard candy for some time before a meal, especially if it is not too sweet nor flavored with acid, helps some people.
Nearly all of them when carefully questioned prove to have special foods that are more difficult of deglutition than others. Not infrequently these idiosyncrasies for food are found to follow ideas with regard to their digestibility. If the patient is hurrying for any reason and suddenly becomes conscious that he is not masticating sufficiently, swallowing at once becomes much more difficult.
The main element in the treatment, however, must be as far as possible to get the patient's mind off his condition. The more attention he gives to it the worse it will be. No treatment that we have will cure it any more than stuttering can be cured, though a deliberate effort to form a habit for the control of the swallowing muscles will often do much to lessen the discomfort and the inability to swallow.
It is important in all these cases to be sure that there has been no incident in childhood which might have caused the production of scar tissue in the esophagus with a consequent stricture. Sometimes it is many years before this manifests itself and, as in the case of the urethra, even ten to twenty years may pass before serious trouble comes. When the first symptoms are noticed, the actual stricture may be so slight as scarcely to be possible of diagnosis by the bougie. Occasionally the first symptom of a cancer of the esophagus is an inability to swallow, and cancers of the esophagus have been known to occur in quite young people, especially young men. I remember seeing a case at autopsy in Vienna where the first symptom had been the difficulty of swallowing and the man, at the recommendation of friends, swallowed a glass of beer with some black peppers in it and these stuck in his esophagus and produced death. Such cases are exceptional but must not be forgotten. Neurotic esophageal stricture is entirely benignant and its prognosis altogether favorable.
Treatment.—The treatment of stuttering presents the best example that we have of the influence of the mind over neurotic difficulties of any and every kind. Many forms of treatment have been announced as successful, most frequently in the hands of men who have themselves been stutterers and who have helped themselves by them. This would seem to make it clear beyond all doubt that discoveries in direct therapeutics had been found. As a matter of fact, however, when a review of all the methods is made, they are seen to be so different from one another and founded on such essentially diverse principles that the only common connecting link to be found is in the occupation of mind with something else besides speech which all these methods recommend. We have had successful cures announced by surgery, by discipline, by making speech more difficult by obstacles of various kinds, by special positions of the tongue—up against the palate or down against the floor of the mouth—by associated movements, by rhythmic speech, by special control of the muscles of respiration, and of many other structures much less related to speech. The interesting phase of all this is the uniform success claimed by different specialists using many different methods.
From the beginning of history cures have been suggested. That idea, still held among the non-medical, that the sufferer from a difficulty of speech is tongue-tied and needs to have the frenum cut, is as old as the history of medicine. Galen suggested cauterization of the tongue. Aetius, the first prominent Christian physician of whom we have any record, divided the frenum of the tongue. So did Paul of AEgina. Of course, in the Renaissance, when the old medical classics were revived, this became a favorite method of treatment. Hildanus is sure that it accomplishes great things. This idea has never been entirely given up, and recurs from time to time in the practice of those who do not reason much, but who look for some ready explanation and, above all, some direct method of treatment. Much more [{577}] serious surgical intervention has been suggested from time to time, however. Velpeau advised division of the extensor muscles of the tongue. Of course a number of surgeons have quite properly insisted on the removal of the tonsils, uvula, polyps in the nose and other obstructions of respiration.
Singing in Treatment.—A number of the stuttering cures employ singing as a method of training in forthright utterance. Few people stutter when they sing. Most people can be given confidence in themselves and their power to talk right on by being shown that as soon as they try to follow a set of notes there is little or no difficulty in utterance. The teaching of singing, then, is of distinct value in many cases. Taking advantage of this a number of those who correct stuttering endeavor to introduce a certain rhythm into speech. So long as the rhythm can be maintained stuttering does not occur. As Kussmaul has pointed out the rhythmus acts as an efficient will-regulator, so that nerve impulses go down regularly and are not interrupted by consciousness and by the sudden starts and stoppages due to fear and tremor and mental uneasiness. Undoubtedly the lesson of this method of teaching is extremely important as an index of how stuttering may be relieved.
Regulation of Respiration.—A number of systems to correct stuttering depend on the regulation of breathing. It has been shown over and over again, and notably by Prof. Gutzman of Berlin, [Footnote 42] that one of the most important differences between stutterers and those who talk naturally is that the normal individual talks during expiration as may be seen in Fig. 23, while the stutterer begins at the end of inspiration or at least where normally on the respiratory curve expiration is just about to begin, but instead of permitting his diaphragm to go up as in ordinary expiration, the stutterer makes it sink lower and lower in a forced inspiration.
