STOMACH (Gr. vrbsaxos from arbga, a mouth)  , the bag-like See also:digestive See also:organ which in See also:man is situated in the upper See also:left See also:part of the See also:abdomen . See, for anatomical details, ALIMENTARY See also:CANAL . For the diseases of the See also:stomach in See also:general see DIGESTIVE See also:ORGANS; and for See also:special forms See also:GASTRITIS, GASTRIC See also:ULCER, See also:DYSPEPSIA, &C.; also ABDOMEN (Abdominal See also:Surgery) . See also:Cancer of the Stomach is a See also:common disease . It occurs for the most part in persons at or after See also:middle See also:life, and in both sexes equally . Its favourite situation is the outlet (pyloric cancer), where a hard, fibrous growth forms a contracting See also:ring of the scirrhous variety . But when cancer attacks the inlet of the stomach, the See also:tumour is of the scaly epitheliomatous variety . It often begins in the tissues of the end of the gullet, spreading downwards to the stomach . Chronic gastric ulcer is not unfrequently the starting point of cancer . The symptoms of cancer of the stomach are See also:apt to be indefinite (for many See also:weeks or months) . There may be See also:long-See also:standing complaints of " indigestion," which is sometimes made better, sometimes worse, by taking See also:food . Then comes a feeling of discomfort which can be often localized, the individual pointing with his See also:finger to a. spot somewhere behind the end of the breastbone .

Difficulty and See also:

pain in swallowing may be complained of when the cancer is beginning to See also:block the inlet, but if it is situated at the pylorus the discomfort comes on an See also:hour or two after a See also:meal—at the See also:time that the partially digested food is trying to make its way into the small See also:intestine . Much of the food remains in the stomach and, undergoing See also:fermentation, causes the See also:evolution of See also:gas which distends the stomach and gives rise to unavoidable belching . Later on vomiting occurs . The vomiting may take See also:place every two or three days, enormous quantities of undigested food mixed with frothy, yeast-like mucous being thrown up . And whilst the stomach is slowly filling up again after one of these uncontrollable emptyings, sudden and violent movements of the individual may cause the fluid to give rise to audible " splashings." But even at this See also:stage the disease may be unrecognizable, though the symptoms are extremely suggestive . But later the vomited See also:matter is blackened by See also:blood which has escaped into the stomach from the ulcerated growth . The patient then rapidly loses flesh and strength, and a hard lump may be See also:felt in the upper part of the abdomen . A characteristic feature of cancer is the carrying of the See also:epithelial cells (which are the essential See also:element of the growth) to the nearest lymphatic glands, and in cancer of the stomach the secondary implication of the glands may cause the formation of large masses between the stomach and the See also:liver, which may See also:press upon the large See also:veins and give rise to See also:dropsy . Secondary deposits are apt to See also:form also in the liver and they may cause the See also:appearance of a bulging below the ribs on the right See also:side . Another characteristic of cancer is that it spreads far and wide, See also:drawing other tissues to itself by contracting fibrous bands . These are sometimes erroneously spoken of as the " roots " of cancer, and in the See also:case of cancer of the stomach they may See also:fix it to the See also:pancreas, the liver, the bowels or the spine . The invasion of the lymphatic glands and the spreading of the growth into neighbouring organs, render the successful operative treatment of gastric cancer hazardous and disappointing .

By the time that a tumour has made itself recognisable the See also:

probability is that it is too See also:late for the See also:attempt to be made for its removal . But in many cases the patient prefers that the abdomen should be opened for exploration for a possible operation than that he should hopelessly give himself over to the disease . And sometimes the surgeon is enabled by operation to give See also:great See also:relief, though the removal of the growth itself is impracticable . When the growth is at the cardiac end of the stomach, blocking the gullet and causing slow See also:starvation, the abdomen may advisedly be opened, and, the stomach having been fixed to the See also:surface-See also:wound, a permanent opening may be arranged for the introduction of an adequate amount of food . This operation is called gastrostomy and may be the means of giving many weeks of comfort to the unhappy patient—provided that its performance is not too long postponed . In the case of pyloric obstruction a permanent opening may be established between the stomach and a neighbouring piece of intestine, so that the food may find its way along the alimentary canal greatly to the relief of the symptoms of gastric See also:dilatation . This is called " See also:short-circuiting." In some See also:early cases of pyloric cancer resection of the disease may be performed, the upper end of the intestine being afterwards joined to the middle of the stomach by a See also:kind of short-circuiting operation . In certain rare cases the whole of the stomach has been removed, the bowel being brought up and spliced to the end of the gullet . In the case of gastric dilatation from pyloric obstruction great relief may be afforded by washing out the viscus by means of a long See also:rubber See also:tube, a See also:funnel, and a See also:jug of hot See also:water, as originally suggested by Adolf Kussmaul . Pyloroplasty.—See also:Simple fibrous narrowing of the gateway of the stomach or of the intestine is dealt with by dividing it longitudinally and then suturing the edges of the wound transversely . This ingenious operation widens the track at the expense of an unimportant fraction of its length . In cases of great dilatation of the stomach with no obstruction to the outlet the slack of the walls may be gathered up by pleating and so permanently secured by suturing .

Loreta's operation for dilatation of the outlet of the stomach is now rarely performed . (E .
