Abstract
PURPOSE: The management of high fistula-in-ano presents a difficult surgical challenge. Laying open of high transsphincteric, intersphincteric, and suprasphincteric fistulas is associated with incontinence. Mucosal advancement flap can be technically difficult and is associated with ectropion and incontinence. We report a new technique for the treatment of fistulas, which may eliminate these problems. PATIENTS AND METHODS: Between 1997 and 2002, 18 patients (13 males), median age 46 (range, 25-64) years with high fistula-in-ano were treated. There were ten transsphincteric, four intersphincteric, and four suprasphincteric fistulas. In all patients, perianal sepsis was allowed to resolve completely with a drainage seton before definitive surgery. The surgical technique used involved core fistulectomy, curettage of any cavity, closure of the defect in the internal anal sphincter, and a V-Y advancement buttock flap to cover the internal opening, leaving the site of the external opening for drainage while preserving both internal and external sphincters. Outcome was assessed in terms of healing and continence. RESULTS: Most patients were discharged from the hospital within 48 hours. Median follow-up was 19 (range, 3-60) months. There were three patients who failed to heal. Of these, two underwent repeat surgery and healed. Two further patients had recurrent fistulas, both of whom continued with conservative treatment. Overall, 15 of 18 (83 percent) patients experienced healing of their fistula. Continence was preserved in all patients. CONCLUSION: This procedure is easy to perform, healing is rapid, and it appears to be effective in curing fistula-in-ano while preserving both external and internal anal sphincters.
