True abscess requires drainage. When a fistula tract can be identified, a seton can be used to prevent premature skin closure and recurrent abscesses. These indwelling setons should be left in place for an extended period (up to 6-12 months) to allow complete epithelialization of the tract as visualized by MRI or EUS. This approach leads to a chronically draining fistula tract. In cases where severe perianal disease has destroyed the sphincter, proctectomy with permanent ileostomy may be necessary.
