Aim: The efficiency of a chemical cauterization technique in
the treatment of high blind tracts, which are important causes
of recurrence in anorectal fistula, were investigated.
Materials and methods: Fifteen patients underwent surgery
for low perianal fistula with high blind tracts. Partial fistulectomy
and cutting seton technique was performed on all patients. The
high blind tracts were cauterized by silver nitrate particles and
the surgical area was left for secondary healing. The follow-up
duration was 6 months to 1 year. The anal continence was
evaluated according to the Wexner score.
Results: Four of the 15 patients were female, whereas 11 were
male. Ages ranged between 17 and 67 years. While 11
participants were primary cases, four were recurrent. Nine of
the fistula tracts were intersphincteric and five were transsphincteric
and one case had horseshoe fistula. The mean
wound healing duration was 5.5 weeks. Mild anal incontinence
(Wexner score = 3) was recorded in one case and recurrence
was observed in another.
Conclusion: Cauterization with silver nitrate is a new treatment
method for high blind tract in anal fistulas. It is a safe and
noninvasive method that reduces recurrences and surgical
complications.
