PROLAPSE OF THE RECTUM 707 



marked. In some cases the prolapse is only noticed when the 

 animal strains in attempting to empty the bowels, and in these 

 cases there is only a small amount of the membrane protruded 

 through the opening, and this usually returns to its regular position 

 in a few minutes after the straining has been stopped. 



If the case be more severe it is not unusual for a fairly good- 

 sized tumor to be seen in the region of the anus. This swollen 

 mass is round, red, or dark-purple in color, and may be somewhat 

 painful when handled. The longer it remains exposed, the larger 

 it becomes and the more dark in color it appears. Finally, it may 

 become dry and show deep cracks or fissures on its surface. The 

 prolapsed part may itch very severely, and as a result the hog rubs 

 it against fence posts, the walls of the shed, and other convenient 

 objects, producing a more severe inflammation and often severe 

 injury to the parts. 



When allowed to remain untreated the animal loses appetite, 

 becomes feverish, and loses weight. The tumor-like mass finally 

 decomposes and may slough off if not taken care of. 

 ^^ Treatment. — Prevention consists principally in proper attention 

 to constipation and other digestive disorders. A mild laxative 

 given to the bound-up animals will empty the bowel of accumulated 

 dry fecal material and stop the straining efforts. In like manner, 

 diarrhea, perverted appetite, and intestinal worms should all 

 receive proper attention in order that severe consequences may be 

 afterward avoided. 



Where prolapse actually exists, the protruding portion of the 

 mucous membrane should be carefully cleansed with a warm anti- 

 septic solution or with warm water and soap. If badly inflamed 

 and swollen it may be washed with a 5 per cent, solution of alum 

 or with a 4 per cent, solution of cocain. The cocain may well be 

 applied after the alum has been used. It relieves the irritation 

 and will allow of the bowel being easily replaced. 



After the tumor mass has been returned to its natural position 

 it is necessary often to use some artificial means of keeping it from 

 again coming out. This may be accomplished by taking one or two 

 stitches across the anal opening, which may be left in position for a 

 couple of days, or a suppository containing 1 gr. of aqueous extract 

 of opium may be pushed up into the rectum once or twice a day.
