 Technic for the Correction of Extra-Vaginal 



Hernia. — In eases of cxtra-vagiital hernia, or in anj^ 

 case where the amount of intestine protruding into 

 the vaginal tunic adjacent to the testicle is consider- 

 able, it becomes necessary to execute a different opera- 

 tion than the one heretofore described. 



The animal should be restrained upon an inclined 

 imi:)rovised table with the head lowermost, and given 

 complete anesthesia of ether or A. C. B. The sur- 

 gical area — region of the groin — should be cleansed 

 with gasoline and painted with tincture of iodin. 

 Serving as a guide, the inner abdominal ring may 

 first be located by palpation, and an incision about 

 four inches long is then made over this site and paral- 

 lel with the course of the vaginal tunic. The tissues 

 are divided by careful dissection and the upper in- 

 guinal region thus exposed makes possible the incising 

 of the vaginal sheath, bringing to view the cord and 

 intestine, provided the intestine has not returned into 

 the peritoneal cavity by gravitation. The margins of 

 the wound made in the vaginal sheath are then seized 

 with forceps and the hernia is reduced. The cord is 

 secured and the testicle drav/n outward and ampu- 

 tated with an emasculator or ligatured with gut and 

 severed with scissors. After amputating the cord and 

 trimming away any excess portions of the vaginal 

 tunic, the cord is then pushed into the peritoneal cav- 

 ity and the inner abdominal ring is closed liy a four 

 or five-point purse-string suture of sterile chromic gut. 

 The skin wound is closed by means of silk sutures and 

 no further attention need be given the subject except 

 to provide clean, sanitary quarters, where they will 

 be unmolested by other animals.
