PROLAPSUS AND INVEl^Sl()N OF TH K KECTUM.

Second stage. Digital exploration of the cavity of the pelvis 

 after breaking down of the layers of connective tissue, and search 

 for the blind end of the floating colon. When discovered, the colon 

 is grasped between the jaws of a clamp or large forceps with smooth 

 jaws, and gently drawn 

 towards the opening. 



Third stage. Punc- 

 ture of the blind end of 

 the colon, and suture of 

 the latter to the cutaneous 

 wound, as in the former 

 case. 



A third condition may 

 exist, where the ex- 

 tremity of the colon re- 

 mains within the abdo- 

 men. Operation by way 

 of the pelvis then proves 

 unsuccessful. If con- 

 sidered advisable, an 

 opening may be made 

 through the right flank, 

 BO that the floating colon 

 may be brought to the 

 surface and an artificial 

 anus produced in this 

 region. 



An incision 1 or 2 

 inches in length is made 

 •below the haunch, to 

 allow of the introduc- 

 tion of the index finger, 

 with w^hich the loop is 

 sought. The colon is withdrawn, and the operation thenceforth is as 

 above described.

PROLAPSUS AND INVERSION OF THE RECTUM. 



This condition occurs in young pigs in various degrees. The 

 necessity for reduction depends on the extent to which tearing or 

 gangrene of the mucous membrane has progressed. The inverted 

 portion is carefully washed, freely dressed with some non-irritant 

 fatty substance such as vaseline, and progressively pushed back with 

 the thumbs and index fingers of both hands applied flat on either
