  • Title: [Pathogenesis and morphology of anal fistulas].
    Author: Jostarndt L, Nitsche D, Thiede A, Schröder D.
    Journal: Fortschr Med; 1984 Jun 14; 102(22):615-8. PubMed ID: 6469167.
    Abstract:
    In a prospective consecutive study in 80 patients with anal fistulous disease we found characteristics in the morphology of the fistulous tracks, which correspond to the structure of anal glands. The theory of a cryptoglandular infection as the cause of anal fistulous disease seems to be realistic for this reason. The chronic fissure in ano represents likewise a pathogenetic factor in the genesis of anal fistula, especially in the posterior part of the anal canal. In this region we found trans- and suprasphincteric tracks with abscesses in the fossa ischiorectalis. Anal fistulas as a consequence of specific intestinal infections could be found only in 6%, whereas unspecific fistulas with inter- and transsphincteric tracks amounted to 90%.
