Background
Crohn's disease is a gastrointestinal disease and is prone to cause a complication, anal fistula. Anal fistulas are the channels formed under the perianal skin that connect obstructed infected glands with abscesses. Typically, treatment of anal fistulas involves abscess drainage, i.e., making an operative opening in the perianal skin, however, in most cases, the fistula tract presents a continuing risk after drainage. Furthermore, even if the skin of the surgical opening heals, a continued fistula trajectory may lead to abscess recurrence. In order to achieve proper healing of the skin of the surgical opening and the fistula tract, the anal fistula patient is subjected to a thread-hanging procedure, i.e., a loop of drug wire is placed over the fistula tract to keep the surgical opening and fistula tract clear. In practice, a medicated thread is threaded through the fistula track and the ends of the medicated thread are then sutured or knotted (over the perianal skin) to form a loop of medicated thread.
