Narrowing of the Intestine. 387 



In a ease reported hj Sporer au obturating potato was crushed after lapar- 

 otomy had been made, and in another case a rough stalk was broken in the middle; 

 both cases then recovered. Feser successfully removed a piece of tin by laparotomy. 



The expulsion of foreign bodies wedged in tlie intestinal 

 tract is favored in dogs by the administration of laxatives. For- 

 eign bodies in the rectum can be removed by hand or with proper 

 extracting forceps. If these methods are not successful, or if 

 they are not applicable from the start on account of the nature 

 of the obstructing body, laparo-enterotomy may be successfully 

 performed, as is shown by the reports of Felizet, Siedam- 

 grotzky, Frolmer, Degive, JPlosz, Marey and others. It is, of 

 course, not advisable to wait long with an operation if it is at 

 all indicated.

22. Narrowing" of the Intestine. Stenosis intestini. 



Stenosis of the intestines is a more or less chronic disease 

 with a generally progressive diminution of the lumen of the in- 

 testine at a circumscribed place. 



Occurrence. .Stenosis of the intestine is a rare affection. 

 It occurs in horses with about the same frequency as obturation 

 of the intestines (see page 379). 



Etiology. The following are the pathologic conditions 

 which may be the causes of intestinal stenosis : Scar formation 

 in the intestinal wall caused by injury through foreign bodies, 

 by ulceration, possibly after gangrene of an intussuscepted 

 portion of the bowel, produces narrowing of the intestinal wall 

 (strictura intestini) in consequence of cicatricial contraction 

 of the newly formed connective tissue. Upon this basis intes- 

 tinal stricture is usually found in the small intestine, the small 

 colon, or the rectum, in domestic animals with the exception of 

 the hog. According to Bruckmuller, Sikorski, Bolton, in horses 

 occasionally, but according to the reports of the Berlin patho- 

 logical institute frequently, a cicatricial stenosis of the ileo- 

 cecal opening is noted, due to chronic inflammation of the mu- 

 cosa and caused by the continuous irritation of coarse feed
