Long-term Follow-up of Anal Fistula Plug for Treatment of Complex Trans-sphincteric Fistulas

Aim of the study is to evaluate long-term success rate of Biodesign® anal fistula plug for treatment of complex trans-sphincteric anal fistulas.

A prospective series of 95 consecutive patients (30 with inflammatory bowel disease) treated with Biodesign® plug in May 2006 - October 2009. All patients were preoperatively assessed by physical examination and 3D endoanal ultrasound, and treated with a loose seton. The patients were assessed by physical examination and 3D endoanal ultrasound at 2 weeks, 3 months, and 6 to 12 months after surgery. Long-term follow-up was carried out using a questionnaire, and, when indicated, physical examination and 3D endoanal ultrasound.
