Tumors of the Intestine in Cattle. 385 



or the whole tumor may be passed at once. Rectal exploration 

 may be intercepted by a rigid stricture, by a tumor blocking the 

 lumen, or a mass may be felt projecting in from one side. Aside 

 from these the situation, form and size of the tumor can some- 

 times be felt through the flaccid walls of the rectum. In other 

 cases the blocked and distended bowels may be felt, without the 

 identification of a tumor as the cause. 



Treatment. For tumors situated in the rectum, the removal 

 by surgical measures (torsion, ecraseur, etc.) is indicated. If 

 the tumor is. simple a permanent cure may be hoped for ; if 

 malignant it is likely to recur.' Tumors situated more anteriorly 

 are usually desperate cases. Yet a certain number of pediculated 

 tumors are detached spontaneously and discharged. In the ab- 

 sence of this, and when a tumor can be certainly diagnosed, 

 there remains a resort to laparotomy, which in the horse is too 

 often unsuccessful. If the tumor can be made out to be malig- 

 nant and multiple it is useless to resort to removal. 



TUMORS OF INTESTINE IN CATTLE. 



Sarcoma : usually near lymph glands. Lipoma : mucosa, serosa, pedicu- 

 lated, strangulation, obstruction. Fibroma : floating colon. Carcinoma : 

 generalized cancer, colon. Cystoma : reticulum, omasum, abomasum. Un- 

 determined tumors. Symptoms : discovery by rectal examination, in case 

 of debility or digestive disturbance. Treatment : removal through rec- 

 tum or by laparotomy, spontaneous sloughing. Hyperplasia of intestinal 

 mucosa. 



Sarcoma. Multiple sarcomata have been found in nearly all 

 parts of the abdominal cavity, but above all in or near the lymph 

 glands. They are from a small size up to masses of 60 lbs. 

 (Revel). 



Lipoma. Fatty tumors are found attached to the mucosa, 

 and peritoneum, but above all as masses with long elastic ped- 

 icles which are liable to wind round and obstruct the intestines. 

 Tannehauer records a case of fatal obstruction of the small in- 

 testine from a lipoma of the mucosa, and Pritchard two cases of 

 fatal obstruction of the rectum by a fatty neoplasm occupying its 

 walls.
