Healing of transsphincteric perianal fistulas in Crohn's disease using a new technique.
OBJECTIVE
Transsphincteric perianal fistulas in Crohn's disease are often refractory to medical therapy and difficult to treat surgically. Our objective was to determine whether a new method of anal fistulotomy was effective in healing these fistulas.


METHODS
In this new method, the internal opening of the fistula tract was displaced distally to the region of the anal mucosa in 26 patients with Crohn's disease.


RESULTS
Healing was achieved within 5 weeks of surgery in 45/49 (92%) of the fistulas and was not influenced by perioperative medication, site of preexisting Crohn's disease, or condition of the rectum. There has been no alteration of preoperative continence.


CONCLUSIONS
We conclude that this method is highly effective in treating transsphincteric perianal fistulas in Crohn's disease.
