STRICTURE OF THE INTESTINE. 



From healing of ulcers, inflammation or infiltration, neoplasms, ring like 

 or sacculated, in small intestine in horse preceded by a dilatation, an effect 

 of verminous trombosis ; in cattle ; in dog. Symptoms : Progressive, if in 

 duodenum can't eat full meal, belches gas, has colics and t3-mpany ; in 

 cattle t3'mpany, unthrift ; in dog vomiting, tympany, colic, accunuilations. 

 Treatment : Gradual stretching by bougies if within reach. 



vStrictures of the intestine are in the main the result of ulcera- 

 tion of the intestinal walls which contract in healing, or inflam- 

 mation, and infiltration which leads to contraction in their 

 organization into tissue. Neoplasms of the walls (cancer, 

 myxoma, lipoma, polypus, melanosis, actinomycosis, tubercle) 

 are additional causes of constriction. If resulting from a lesion 

 which completely encircled the bowel there is an uniform con- 

 striction in the form of a circular ring ; if on the other hand it 

 started from a longitudinal ulcer or lesion the bowel is .shortened 

 on that side and puckered. 



In solipeds strictures are most frequent in the small intestine, 

 or rectum. The pylorus is often affected. When on the small 

 intestine there is constantly a dilatation just in front of the ob- 

 struction. The constricted portion is usually short, but as seen 

 from outside of the gut may be duplicated a number of times. 

 Cadeac mentions seventeen such strictures in the same animal, 

 each preceded by a dilatation. The individual stricture \wa.y be 

 less than two inches in length and so narrow as ju.st to allow the 

 pas.sage of the index finger. The walls of many times their 

 natural thickness, are still further thickened by an external layer 

 of adipose tissue. It may be the seat of a small abscess, or of a 

 tumor. Internally the mucosa may show ulcerations. 



The stricture or .strictures in .solipeds often depend on the dis- 

 turbance of the circulation which results from verminous throm-
