Brief Summary

The investigators aim to assess the efficacy of the Curaseal anal plug in patients with idiopathic uncomplicated fistulous tracts. Healing of the fistula tract will be assessed both clinically and radiologically with MR imaging.

Detailed Description

Perianal fistula is a challenging condition for colorectal surgeons. Achieving a favourable balance between healing and incontinence is the key to success. Surgeons have adopted many methods to close off this abnormal tract, which include laying opening, use of setons, advancement flaps and permanent stoma. A more recent approach has been the use of devices or substances to block the tract in the hope that it will seal off. Most of the devices that have been used to close the tract have not proved to be as effective in healing as a lay open with high rates of fistula persistence. A major failure of the devices has been their early expulsion and their inability to seal off the internal opening.

The new Curaseal plug may be able to overcome these shortcomings. This plug has a disc to seal the internal opening, with a suture to be placed at the external opening, which may prevent it falling out and ensure internal opening closure.

The investigators aim to assess the efficacy of the Curaseal anal plug in patients with idiopathic uncomplicated fistulous tracts. Healing of the fistula tract will be assessed both clinically and radiologically with MR imaging.
