A CLINICO.PATHOLOGICAL STUDY OF ANAL FISTULAE

Anal Fistula
Revle* of Literature
This hy?othesis postulates that infection starts in anal gland lying
within inter sphincteric plene at line of anal valves (dentate line).
As the abscess expimds pus may traok longitudinally, up or down, in
the inter sphincteric, submucous or extra sphincteric planes to present as a
perianal, ischiorectal or supra levator abscesses.
f
Circumferential tracking can similarly occur along these planes to
form horse shoe abscess. The fistula is complete when the abscess
spontaneously discharges or the surgeon prOvides this corununisation.
Secondry fiacks complicate the situation rspresent upward extension
into the supralevator $pase or lateral extension into the ischiorectal fossa
(Lnttimer et aL, 1996).
