Part 101

In general, the prognosis is more favorable in dilatation without stenosis. If the degree of dilatation be only moderate, a permanent cure may often be effected by proper treatment. If, however, the dilatation be considerable, while the symptoms may be relieved or even made to disappear for a time, relapses are prone to occur, and a permanent cure is rarely obtained. Undoubtedly, Kussmaul's publication in 1869, in giving to us a most valuable method of treatment, at the same time raised extravagant expectations of the frequency with which dilatation of the stomach can be cured. Too often the treatment with the stomach-tube proves only palliative and not curative.

The course of dilatation of the stomach is chronic. The mode of death is usually by inanition, very rarely from rupture of the stomach.

TREATMENT.--Reference to the causation of dilatation of the stomach will show that there is considerable scope for the prophylactic treatment of dilatation not referable to stenosis or incurable organic disease. Thus, the correction of the habits of eating or drinking inordinate quantities, or of imperfectly masticating the food in consequence of haste or bad teeth or vicious custom, may avert the development of gastric dilatation. Of especial importance is the timely treatment of cases of dyspepsia or of chronic catarrhal gastritis which are accompanied with fermentation or delayed digestion--conditions in which the stomach-tube is of great service.

Of the means at our disposal for meeting the causal and the symptomatic indications of dilatation of the stomach, the most important by far is the use of the stomach-tube for the purpose of emptying and of washing out the stomach. The introduction of this procedure by Kussmaul in 1867 marked a new era in the treatment of gastric disorders.

{604} By washing out the stomach we accomplish three important things: first, we remove the weight which helps to distend the organ; secondly, we remove mucus and stagnating and fermenting material which irritates and often inflames the stomach and impedes digestion; and, thirdly, we cleanse the inner surface of the stomach and obtain the beneficial influence of the direct application of water, to which various medicinal substances can be added. It is probable that in removing the fermenting contents of the stomach we also remove a possible source of self-infection of the system (see page 596).

By accomplishing these things we may possibly also enable the stomach to regain its lost elasticity and muscular contractility. But unless the normal elastic and contractile powers of the stomach are restored, the treatment with the stomach-tube, indispensable as it is for the relief of symptoms, is only palliative and not curative. Whether or not this restoration of the stomach to its normal functional activity is to be expected depends chiefly upon the cause and the degree of the dilatation. Unfortunately, as has already been stated under Prognosis, the permanent cure of dilatation of the stomach due to organic stenosis, although possible, is not to be expected, and the number of cases in which largely dilated stomachs can be restored to their normal volume or made to perform permanently their normal functions is small. There remains, however, a considerable number of curable cases--to be sure, not always easily diagnosticated--in which the muscular coat of the stomach has not been seriously damaged and in which the dilatation is generally only moderate. Furthermore, excellent results are obtained by the use of the stomach-tube in the cases which have been designated insufficiency of the stomach, and which are closely allied to dilatation--in fact, often represent its early stage. As has already been mentioned, the most important criteria of this so-called insufficiency are the fermentation of the contents of the stomach and the presence therein of undigested food after the period required for normal digestion (six to seven hours for an ordinary meal).

There are two principal methods of washing out the stomach--one by the stomach-pump, the other by the siphon process. The stomach-pump is the older method, and still has its advocates. The pump used by Kussmaul is the Wyman pump, described by Bowditch in the American Journal of Medical Sciences, vol. xxiii. p. 320, 1852. This (which is also called the Weiss pump), as well as other forms of stomach-pump, consists in principle simply of an aspirating syringe having at its anterior extremity two openings communicating with the barrel of the syringe. These openings can be alternately opened and closed by means of an arrangement of valves. Through one opening, which is made to communicate with an incompressible tube inserted into the stomach (the other opening being now closed), the gastric contents are drawn into the barrel of the syringe. This opening is now closed, and through the other opening the contents of the syringe are discharged through a tube externally. In a similar way fluid can be drawn into the syringe and pumped into the stomach.

In the siphon process the outer end of the tube inserted into the stomach is connected with a piece of elastic tubing about three and a half feet long, in the free end of which is inserted the extremity of a medium-sized glass funnel. A single elastic tube about six feet long may also be used. {605} When the funnel is elevated, water which has been poured into it will run into the stomach. If now, before the water has all run out, the funnel be depressed below the level of the stomach, the fluid contents of the stomach will flow out through the tube according to the principle of the siphon. Figs. 20 and 21 will make clear the mode of operation of this process. (The tube shown in these figures is the Faucher tube, commonly used in France, and consisting, with the funnel, of one piece. A longer tube than that shown in the figure should be used.)

Another convenient but somewhat more complicated method of employing the siphon process is according to Rosenthal's principle, and is represented in Fig. 22. To the outer end of the stomach-tube is attached a Y-shaped glass tube, one arm of which is connected with an elastic tube running to an irrigator, while the other arm is connected with the discharging tube. Through the irrigating tube water runs into the stomach, the discharging tube being compressed. If the discharging tube be opened while the fluid is flowing from the irrigator, and if then, after the establishment of a column of water in the discharging tube, the irrigating tube be compressed or the stopcock of the irrigator be closed, a siphon communicating with the stomach is formed and empties this organ of its fluid contents.

In the siphon process the tube inserted into the stomach may be an incompressible hard-rubber tube like that employed with the stomach-pump, but by far the simplest, most convenient, and safest form of stomach-tube is the soft, flexible, red rubber tube, resembling the Jacques catheter, but of course larger and longer. This soft tube can inflict no {606} injury, and in most cases it is readily introduced. Generally, the patient himself can best manipulate the introduction of the tube. After the tube is introduced into the pharynx, the patient, who should be in a sitting posture, makes repeated acts of swallowing, by means of which, accompanied by directing and gently pushing the tube with the fingers, the tube passes along the oesophagus into the stomach. Often at first the nervousness and inexperience of the patient occasion some trouble, but after a little practice he generally succeeds in introducing the tube without discomfort or difficulty. Before its introduction the tube should be anointed with a little vaseline or some similar substance. In an adult the tube is introduced for a length of at least 20 to 25 inches, and in cases of dilatation of the stomach of course for a greater distance. Whatever form of stomach-tube be used, it is important that the tube should be at least 30 inches long, and should be provided with one, and preferably with two, large eyes at its distal extremity.

Oser's tube is 2 meters long, and is made of mineralized rubber. There are two sizes. The smaller has a lumen of 8 mm. The thickness of the wall is 2½ mm. In the larger tube the lumen is 10 mm., and the thickness of the wall 3 mm. He generally uses the smaller tube.

Faucher's tube is 1½ meters long. The external diameter of the tube is 10 to 12 mm. The walls are of such thickness that the tube can be bent without effacing its lumen. At one extremity is a lateral eye with two orifices. To the other extremity is adapted a funnel with a capacity of about 500 grammes.]

Although the stomach-pump has the advantage of more completely evacuating the stomach and of removing coarser solid particles than is possible with the siphon, nevertheless its disadvantages--namely, the possibility of inflicting injury to the mucous membrane of the stomach, the expense and greater complexity of the instrument, and the circumstance that it should be used only by the physician--in contrast with the advantages of the siphon--namely, its cheapness, simplicity, safety, and possible employment by the patient or his attendants--have led to the general adoption of the latter process. Only the soft-rubber stomach-tube should be left to the employment of the patient.

Sometimes the flow through the siphon is interrupted by occlusion of the eye of the stomach-tube by a solid mass or by some cause not always clear. As already mentioned, it is desirable that there should be two openings at the gastric extremity of the tube. When the flow is {607} interrupted the position of the tube in the stomach may be changed, or the patient may be directed to cough or to exert the pressure of the abdominal muscles, or more water may be allowed to run into the stomach in order to displace an occluding mass in the tube. It is, however, well for such cases to have, if possible, a stomach-pump and an incompressible tube in reserve. Moreover, as is apparent from the foregoing statement of the advantages of the stomach-pump, there are cases in which this instrument is much more useful than the siphon, so that one cannot decide unconditionally in favor of one instrument over the other.

The stomach-tube should be secured so that there can be no possibility of its being swallowed entirely. A string may be attached to the distal end of the tube. Leube has reported an instance in which the whole tube disappeared into the stomach, and Jackson has also narrated a case in which an insane patient swallowed the stomach-tube. In both cases the tube was subsequently rejected by vomiting.

For washing out the stomach after the greater part of the contents have been withdrawn, about a pint of tepid fluid is allowed to slowly run into the stomach, and is then siphoned out. This process is to be repeated several times. In general, tepid water suffices for washing out the stomach, but it is often better to use, at least a part of the time, a 1 to 2 per cent. solution of bicarbonate of sodium, which facilitates the removal of mucus. The artificial and the natural Vichy and Carlsbad waters are also excellent for this purpose. Various additions are also made to the water with the view of counteracting fermentative changes in the stomach. For this purpose perhaps the best agents are salicylate of sodium (1 per cent. solution) or resorcin (2 per cent. solution). Other substances which have also been recommended are carbolic acid, permanganate of potassium, hyposulphite of sodium, creasote, benzine. Simple water, however, accomplishes about all that is possible, and many are satisfied to use it without any medication.

As regards the frequency with which the stomach is to be washed out, one is to be guided by the symptoms and the effect obtained by the use of the stomach-tube. As a general rule, it suffices to wash out the stomach once a day, and often the process need be repeated only every second or third day.

Opinions are divided as to the best time of day to select for washing out the stomach. Kussmaul recommends the morning before breakfast, and the majority have followed his advice; others prefer the evening. There is much, however, in favor of washing out the stomach about half an hour before the principal meal of the day. The best opportunity has been offered for the digestion and absorption of the food taken at the previous main meal, and the stomach is placed in the best possible condition for the reception of more food.

The habitual washing out of the stomach is not without its drawbacks. We often remove, as has been pointed out especially by Leube, not only noxious substances from the stomach, but also the completed products of digestion. To withdraw from the nourishment of the body this chyme which the stomach has laboriously manufactured cannot be a matter of indifference. Still, with the weakened absorptive powers of the stomach, {608} and its inability to properly propel its contents into the intestine, it is a question how much of this chyme would eventually be utilized for nutrition. Another point is worthy of attention. The relief which the patient experiences when his overloaded stomach is freed of its burden, and the knowledge that this method of relief is always at hand, may make him careless in the observance of the dietetic rules which are of great importance in the treatment of this disease. It is well, therefore, not to wash out the stomach oftener than is necessary, nor to continue the habitual use of the stomach-tube longer than is required.

There are contraindications to the use of the stomach-tube. In very rare instances the attempt to introduce the tube causes the patient so much distress, produces such violent spasm of the pharyngeal and adjacent muscles, or induces so much retching and vomiting, or is attended with such prostration or even syncope, that this method of treatment has to be abandoned. Great weakness, recent gastric hemorrhage, ulcer of the stomach in most cases (see page 523), often cancer of the cardia or of the oesophagus, and aneurism of the aorta, are contraindications to the use of the stomach-tube.

If we group together the results obtained by the use of the stomach-tube in gastric dilatation, we shall find cases in which no benefit results; cases which are benefited, but are obliged to continue the use of the stomach-tube throughout life; cases in which recovery is slow and gradual; cases with more or less speedy relief or apparent cure, but followed by relapses; and cases of prompt relief and permanent cure.

The regulation of the diet is never to be neglected in cases of dilatation of the stomach. Here the guiding principles are that little fluid should be taken, and that the food should be small in bulk, nutritious, easily digestible, and not readily undergoing fermentation. The patient should drink as little water as possible, and should therefore avoid whatever occasions thirst. It is hardly practicable to carry out the plan of giving water mostly by the rectum, as has been proposed. In most cases milk is useful, but an exclusively milk diet is not generally well borne on account of the quantity of fluid required. Leube's beef-solution is often serviceable. Soft-boiled eggs and tender meats are to be allowed, particularly the white meat of fowl and rare beefsteak, especially that prepared from scraped and finely-chopped beef, as recommended in the treatment of gastric ulcer (page 521). Fatty, saccharine, and amylaceous articles of food--hence most vegetables and fruits--are to be avoided on account of their tendency to undergo fermentation in the stomach. Alcohol in any form is usually detrimental. If gastric symptoms, particularly vomiting, be very urgent, or if food introduced into the stomach affords little or no nourishment, as in some cases of tight pyloric stricture, then rectal alimentation is to be resorted to.

An important indication is to restore the tone and contractile power of the muscular coat of the stomach. For this purpose electricity, in the form both of the constant and of the faradic current, has been beneficially employed. The best results are reported from the use of the faradic current. Both poles may be applied over the region of the stomach. The application of electricity to the inside of the stomach by means of electrodes attached to stomach-tubes or bougies is a more {609} difficult procedure, but has its advocates. Uniformly good results are not obtained by the use of electricity in gastric dilatation, but there can be no doubt that in some cases decided benefit follows this method of treatment.

Nux vomica, particularly its alkaloid strychnia, has been much employed with the view of stimulating the muscular power of the stomach. Strychnia is given either internally or hypodermically. Hypodermic injections of ergotin have also been used for the same purpose. It has been hoped to increase the contraction of the stomach by cold applications to the abdomen, as by ice-bags applied immediately after washing out the stomach. The benefit derived from these various attempts to increase the tonicity of the gastric muscle is not very apparent.

A belt or bandage around the abdomen in order to support the stomach sometimes makes the patient feel more comfortable; in other cases it aggravates the symptoms.

In many cases digestion is promoted by giving dilute hydrochloric acid with or without pepsin. About ten drops of dilute hydrochloric acid may be given half an hour to an hour after each meal.

When the stomach is systematically washed out, the individual symptoms of dilatation of the stomach will rarely require special treatment. The sensation of fulness and weight in the stomach, the eructations, the vomiting, and the constipation are generally relieved, at least temporarily, by washing out the stomach. The appetite is improved, and an increase in weight is usually soon noticeable.

If heartburn and eructations of gas continue troublesome, an antacid, such as bicarbonate of sodium or prepared chalk, will be found useful.
