Prevalence and Characteristics of Transsphincteric Anal Fistulas Unclassifiable by the Sumikoshi Classification: A Single-center Retrospective Study

Type IIT is not rare (6.0%) and should be treated as a complex fistula because of the greater involvement of the external anal sphincter. Surgeons may benefit by including type IIT as a new type II subclass in the Sumikoshi classification system.
