DISEASES OF THE DIGESTIVE APPARATUS 



from the anus; this is a thick yellowish-brown liquid, often stained with

 breaks through the skin at the anus, forming an anal fistula. 



The treatment consists in pressing the engorged glandular tissue be- 

 tween the fingers, either the two fingers externally, or putting the index 

 finger into the rectum, and pressing on the pouches. If they cannot be 

 emptied in this manner, they must l)e opened by means of a curved bis-

instances it is necessary to curette the pouches. The general condition 

 may be assisted by laxatives, to assist in easier defecation.

 situated in the sphincter, forming the anus, become inflamed and cause 

 a swelling of the entire neighborhood of the anus, causing great inter- 

 ference with defecation. These generally form pus, fluctuate and break. 

 The treatment consists in opening the abscesses and treating them 

 antiseptically. 



Diverticulum of the Rectum, Pseudo-perineal Hernia. — From the fre- 

 quent accumulation of fa^'/cs in the rectum, particularly in old animals, 

 the terminal portion of the floating colon and rectum becomes dilated and 

 forms a sac, and when this diverticulum becomes filled, the neighboring 

 structures are pushed out, and the condition may be mistaken for perineal 

 hernia (Fig. 39.) It can be differentiated from hernia by the fact that
