[Fistulectomy with closure by first intention in the treatment of perianal fistulae].

The authors report in a retrospective study their experience in the treatment of anal fistulas suggesting the total exercises of the fistula with primary closure of external and internal anal sphincters and rectal mucosa. In our department of surgery between 1987 and 1993, 36 patients (22 males and 14 females) with anal fistulas (17 intersphincteric, 15 trans-sphincteric and suprasphincteric) were treated with this technique. Postoperative in-hospital stay ranged between 2 and 5 days (mean 3.1) and surgical healing needed 12-15 days. A dehiscence of distal tract was observed in 3 cases (8.2%). in these cases secondary closure of the wound needed 24-28 days. All the patients controlled at follow-up (it lasted at least 1 year) did not show rectal incontinence for gas or stools. The authors conclude that total exeresis with primary closure is a safe procedure indicated in the treatment of anal fistula not associated to inflammatory bowel disease in consideration of earlier healing and minor costs.
