The meaning of high ligation in terms of male surgery mainly includes high ligation for varicocele surgery and high ligation for traffic syringomyelia surgery. Elevation is an anatomical concept that refers to the location of or above the internal ring opening of the inguinal canal. Varicocele surgery includes traditional high ligation and laparoscopic high ligation, both of which are high ligation as the ligation site is located at or above the internal ring opening. Sphincter ligation for traffic syringomyelia is also performed at the level of the internal orifice of the inguinal canal, so it is also a high level ligation.
