 six inches parallel to the median line and one to one and a half inches 

 from it. <^ i.-^pj 



The sac (tunica vaginalis) containing the testicle should then be isolated 

 or detached by blunt dissection and tearing wp the inguinal canal to within 

 about two inches of the internal abdominal ring. 



Before proceeding further all blood-vessels of sufficient size should be 

 ligated. The sac (tunica vaginalis) should then be opened and the testicle 

 taken hold of and held witli one hand while the loop of intestine (J) is 

 gradually replaced through the internal inguinal ring (P) (See Fig. 36)

 passed up tlie inguinal canal. If a loop of bowel happens to be distended 

 by gas it should be punctured with a small trocar and canula. 



The scrotum may be packed with sterile gauze if considered advisable. 

 However, scrotum packing is not usually necessary.
