Part 79

In 444,564 deaths in New York City from 1868 to 1882, inclusive, ulcer of the stomach was assigned as the cause of death only in 410 cases. Little value can be assigned to these statistics as regards a disease so difficult of diagnosis.]

{486} Gastric ulcer is more common among the poor than among the rich. Anxiety, mental depression, scanty food, damp dwellings, insufficient exercise, and exposure to extreme cold are among the depressing influences which have been assigned as predisposing causes of gastric ulcer, but without sufficient proof.

The comparative frequency of gastric ulcer among needlewomen, maidservants, and female cooks has attracted the attention of all who have had large opportunity for clinical observation.

Pressure upon the pit of the stomach, either by wearing tight belts or in the pursuit of certain occupations, such as those of shoemaking, of tailoring, and of weaving, is thought by Habershon and others to predispose to ulcer of the stomach.

Vomiting of blood has been known in several instances to affect a number of members of the same family, but beyond this unsatisfactory evidence there is nothing to show hereditary influence in the origin of gastric ulcer.

In a few cases injury of the region of the stomach, as by a fall or a blow, has been assigned as the cause of ulcer. The efficacy of this cause has been accepted by Gerhardt, Lebert, Ziemssen, and others. In many of the cases in which this cause has been assigned the symptoms of ulcer appeared so long after the injury that it is doubtful whether there was any connection between the two.

That loss of substance in the mucous membrane of the stomach may be the result of injury directly or indirectly applied to this organ cannot admit of question. But it is characteristic of these traumatic ulcers that they rapidly heal unless the injury is so severe as to prove speedily fatal. Thus, Duplay relates three cases in which pain, vomiting, repeated vomiting of blood, and dyspepsia followed contusions of the region of the stomach. But these traumatic cases, which for a time gave the symptoms of gastric ulcer, recovered in from two weeks to two months, whereas the persistence of the symptoms is a characteristic of simple ulcer.

In the same way, ulcers of the stomach produced by corrosive poisons as a rule soon cicatrize, unless death follows after a short time the action of the poison. That corrosive ulcers may, however, be closely allied to simple ulcers is shown by an interesting case reported by Wilson Fox, in which the immediate effects of swallowing hydrochloric acid were recovered from in about four days, but death resulted from vomiting of blood two weeks after. At the autopsy the source of the hemorrhage was found in an ulcer of the pyloric region of the stomach. An equally striking case is reported by Williams. A boy who suffered severely for three or four days after drinking some strong mineral acid recovered, so that he {487} ate and drank as usual. Two months afterward he died suddenly from perforation of a gastric ulcer.

While, then, it would be a great error to identify traumatic and corrosive ulcers of the stomach with simple ulcer, it is possible that either may become chronic if associated with those conditions of the stomach or of the constitution, for the most part unknown to us, which prevent the ready healing of simple ulcer.

Gastric ulcer is often associated with other diseases, but it occurs also uncomplicated in a large number of cases. Most of the diseases with which it has been found associated are to be regarded simply as coincident or complicating affections; but as some of them have been thought to cause the ulcer, they demand consideration in this connection.

The large share taken by pulmonary phthisis in deaths from all causes renders this disease a frequent associate of gastric ulcer. It is probable that the lowered vitality of phthisical patients increases somewhat their liability to gastric ulcer. Moreover, it would not be strange if gastric ulcer, as well as other exhausting diseases, such as diabetes and cancer, diminished the power of resisting tuberculous infection. Genuine tuberculous ulcers occur rarely in the stomach, but they are not to be identified with simple ulcer.

There is no proof that amenorrhoea or other disorders of menstruation exert any direct influence in the production of gastric ulcer, although Crisp went so far as to designate certain cases of gastric ulcer as the menstrual ulcer. Nevertheless, amenorrhoea is a very common symptom or associated condition in the gastric ulcer of females between sixteen and thirty years of age.

Chlorosis and anæmia, especially in young women, favor the development of gastric ulcer, but that there is no necessary relation between the two is shown by the occurrence of ulcer in those previously robust. Moreover, it is probable that in some cases in which the anæmia has been thought to precede the ulcer it has, in fact, been a result rather than a cause of the ulcer.

Especial interest attaches to the relation between gastric ulcer and diseases of the heart and of the blood-vessels, because to disturbances in the circulation in the stomach the largest share in the pathenogenesis of ulcer has been assigned by Virchow. As might be expected, valvular lesions of the heart and atheroma of the arteries are not infrequently found in elderly people who are the subjects of gastric ulcer. A small proportion of cases of ulcer has been associated also with other diseases in which the arteries are often abnormal, such as with chronic diffuse nephritis, syphilis, amyloid degeneration, and endarteritis obliterans. But, after making the most generous allowance for the influence of these diseases in the causation of ulcer of the stomach, there remains a large number of cases of ulcer in which no disease of the heart or of the arteries has been found. Gastric ulcer develops most frequently between fifteen and forty years of age, a period when arterial diseases are not common. Changes in the {488} blood-vessels of the stomach will be described in connection with the morbid anatomy of gastric ulcer.

Chronic passive congestion of the stomach in cases of cirrhosis of the liver, direct injury to the mucous membrane of the stomach by parasites in trichinosis, hemorrhage into the coats of the stomach in scorbutus and in dementia paralytica, persistent vomiting in pregnancy, and anæmia induced by prolonged lactation, have each been assigned as causes in a few cases of gastric ulcer, but they are not associated with gastric ulcer in enough cases to make their causative influence at all certain.

Galliard assigns diabetes mellitus as the cause in one case of gastric ulcer.

Rokitansky attributed some cases of gastric ulcer to intermittent fever.

Those who believe in the inflammatory origin of ulcer of the stomach think that chronic gastritis is an important predisposing cause.

The abuse of alcohol is admitted as an indirect cause of gastric ulcer by the majority of writers.

Lastly, burns of the skin, which are an important factor in the etiology of duodenal ulcers, have been followed only in a very few instances by ulcer of the stomach.

The direct causes of ulcer of the stomach, concerning which our positive knowledge is very limited, will be considered under the pathenogenesis of the disease.

SYMPTOMATOLOGY.--The following classes of cases of gastric ulcer may be distinguished:

First: Gastric ulcer may give rise to no symptoms pointing to its existence, and be found accidentally at the autopsy when death has occurred from some other disease. This latent course is most frequent with gastric ulcers complicating chronic wasting diseases, such as tuberculosis, and with gastric ulcers in elderly people.

Second: Gastric ulcer may give rise to no marked symptoms before profuse hemorrhage from the stomach or perforation of the stomach, resulting speedily in death, occurs. Acute ulcers in anæmic females from fifteen to thirty years of age are those most liable to perforate without previous symptoms.

Third: Gastric ulcer may occasion only the symptoms of chronic gastritis, or of functional dyspepsia, or of purely nervous gastralgia, so that its diagnosis is impossible. In this class of cases after a time characteristic symptoms may develop. Here, too, sudden death may occur from hemorrhage or from perforation.

Fourth: In typical cases characteristic symptoms are present, so that the diagnosis can be made more or less positively. These symptoms are pain, and hemorrhage from the stomach, associated usually with vomiting and disturbances of digestion.

The different symptoms of gastric ulcer will now be described.

Of all the symptoms, pain is the most constant and is often the first to attract attention. It is absent throughout the disease only in exceptional cases. In different cases, and often in the same case at different times, the pain varies in its quality, its intensity, its situation, its duration, and in other characteristics.
