In the =dog= much may be expected from the use of emetics, (ipecacuan, tartar emetic, apomorphine, tepid water, tickling the fauces). In some cases of sharp pointed bodies an exclusive and abundant diet of well boiled potatoes proves successful. The object is to pass much of the starchy matter through the small intestines undigested, so that it may envelop the sharp body and protect the mucosa. When it reaches the colon, the ingesta as a whole becomes more solid and invested by this, the body is often passed without danger. Other methods failing laparotomy remains. The dog is stretched on his back on a table with the forelimbs held well apart. The skin of the epigastrium is denuded of hair and washed with antiseptics (mercuric chloride solution 1:500). Hands and instruments are also made aseptic. Then an incision is made in the epigastrium or in the situation where the offending body has been felt, and the finger is introduced to locate the body. At this point a thread is passed through the walls of the stomach, and these are drawn well out through the abdominal wound and incised to the extent of an inch or more. Through this orifice the foreign body can be easily felt and extracted. Then in case the stomach is over-filled it may be emptied, and the edges washed with the antiseptic and carefully sutured with sterilized catgut. The usual care must be taken to turn the mucosa inward and bring the muscular and serous coats in accurate opposition. Finally the abdominal wound is closed by a continued suture of silk or catgut. The greatest care must be taken to prevent the escape of any of the gastric contents into the abdominal cavity, to render both wounds aseptic and to protect the external wound especially against infection. A wash of carbolic acid (1:100) with a little of some intense bitter (quassia) will often succeed in preventing licking or gnawing. Even greater care must be given in the matter of diet. At first a few teaspoonfuls of cold water only need be given. After twenty-four hours a little well strained beef tea; later milk or gruel may be added, and by degrees more solid food. In three weeks the ordinary food may usually be resumed. In case the foreign body has escaped into the peritoneal cavity, the same method may be pursued, the edges of the gastric or intestinal wound being made raw, treated antiseptically and carefully sutured, and the abdomen washed out with an antiseptic solution (aluminum acetate solution) and closed. TUMORS OF THE STOMACH. In horse—sarcoma, papilloma, lipoma, adenosarcoma, epithelioma, in cattle—scirrhus, in dog—sarcoma, lipoma, epithelioma. Symptoms: chronic gastritis, periodic indigestions, colics, vertigo, salivation, impacted gullet, blackened fæces, eructations, vomiting, rumbling, stiffness, emaciation. Treatment: laparotomy in dog.
