Levator Ani Muscle Posterior Midline Incision Method for Diffrentiation of Anal Fistulas Involving Ischioretal and Pelvirectal Spaces.: Lim, Seok Won; J Korean Soc Coloproctol. 2008;24(1):72-74.; DOI: https://doi.org/10.3393/jksc.2008.24.1.72

Abstract PDF: The difference between anal fistulas involving the ischioretal space and pelvirectal space is that in the former the involvement of the anal fistula is low the levator ani muscle whereas in the latter it is above the levator ani muscle. The levator ani muscle posterior midline incision method, which is introduced here, is thought not to injure the anal sphincter; thus, it does not affect the anal function. The method also allow the surgeon to assess readily and accurately whether or not the fistula has invaded the pelvirectal space.
