234 CAiX/NE A.XD FELINE SURGERY 



Another method consists in opening the sac, ligaturing the 

 cord with aseptic silk as high up as possible, removing the 

 testicle, and closely suturing the end of the sac, the skin 

 being stitched and dressed afterwards in the usual way. 

 Occasionally the intestine can be returned and the canal 

 drawn together with sutures so that the neck of the sac 

 is too narrow to admit the prolapsed gut again, and vet 

 does not press upon the vessels or other structures of 

 the cord. 



If castration is not to be practised, and the hernia keeps 

 returning after being repeatedh' reduced, laparotomy may be 

 performed, the herniated intestine withdrawn and sutured to 

 the abdominal wall (see p. 211). 



Perineal Hernia. 



This occurs as a soft swelling at the side of the anus ; it is 

 not so common as the inguinal or umbilical varieties. 



The herniated organs are usually omentum or bowel, and 

 the bladder is not infrequently included. The author has 

 met with five such cases within a comparatively short time. 

 If the latter is present, it is of considerable danger to the 

 patient, and may cause retention of urine and excessive pain. 

 Under such conditions the urine must be withdrawn either 

 by the catheter or, if that is impossible, by a fine trocar and 

 cannula. 



In the case of the dachshund, represented by the photograph in 

 Fig- 152, the omentum was the only organ herniated, and the patient 

 Hved to a good old age, suffering no pain, but merely a certain amount of 

 inconvenience. 



Fig. 153 represents a perineal hernia in an aged collie, which contained 

 the bladder and a certain amount of omentum. The bladder used to 

 become distended, causing great pain, and the urine was drawn away 

 on numerous occasions with a catheter. On five separate occasions, 

 however, this was impossible, and a fine exploring trocar and cannula was 

 used, with most excellent results. It was an impossible case upon which 

 to attempt the radical cure.
