Background
The aim of this study was to report a simple, effective and safe procedure, associated with minimal risk of incontinence and recurrence, for treating complex anal fistulas.
Methods
This was a prospective study of 53 consecutive patients with complex anal fistulas. The technique used included excision of the distal part of the fistula tract down to the external anal sphincter and electro-cauterization of the intersphincteric part of the tract with simple closure of the internal opening. Data collected included patient characteristics, fistula type determined by magnetic resonance imaging, pre- and postoperative continence status evaluated using the Wexner incontinence score (0–10), previous operations, hospital stay, healing time, recurrence rate and complications.
Results
The patients had a mean age of 41.37 ± 7.82 years; the most frequent fistula type was the high transsphincteric fistula; the mean follow-up period was 19 months with a success rate of 92.5 %; the mean wound healing time was 3.6 weeks; the incontinence scores were the same as before the procedure. The recurrence rate was 7.5 %.
Conclusions
Partial fistulectomy combined with electrocauterization of the intersphincteric fistula tract is a simple, and effective procedure for the treatment of complex anal fistulas.
