| - Brief summary | Background: Low transsfincteric fistulas less than 1/3 of the sphincter complex are easy to treat by fistulotomy with a high success rate. High transsfincteric fistulas remain a surgical challenge. Various surgical procedures are available, but recurrence rates of these techniques are disappointingly high. The mucosal flap advancement is considered the gold standard for the treatment of high perianal fistula of cryptoglandular origin by most colorectal surgeons. In the literature a recurrence rate between 0 and 63% is reported for the mucosal flap advancement. Recently Armstrong and colleagues reported on a new biologic anal fistula plug, a bioabsorbable xenograft made of lyophilized porcine intestinal submucosa. Their prospective series of 15 patients with high perianal fistula treated with the Anal Fistula Plug showed promising results. Objectives: To compare the Anal Fistula Plug with the mucosal flap advancement in the treatment of high perianal fistula in terms of success rate, continence, postoperative pain. Patients and Methods: A total of 60 patients who are planned to undergo surgery because of high perianal fistula will be included in a double blinded randomised controlled trial to compare the Anal Fistula Plug with the mucosal flap advancement. Study parameters will be anorectal fistula closure-rate, quality of life, post-operative pain, and continence. Follow-up: Patients will be followed-up at two weeks, four weeks, 16 weeks. At the final follow-up closure rate is determined by clinical examination. |
