Anal Fistula Treatment Outcome - Collagen Plug Versus Advancement Flap Surgery
Comparison of Anal Fistula Treatment Outcome - Collagen Plug vs Advancement Flap Surgery. A Randomised Prospective Blinded Multi-centre Study

The purpose of this study is to determine whether the outcome of anal fistula repair with a collagen plug is comparable to that of repair by a mucosal advancement flap.

Perianal fistula can occur as a complication to a perianal abscess. A perianal fistula is associated with significant morbidity and reduced quality of life. Anal fistulas seldom heal spontaneously and may require surgical intervention. The main purpose of the operation will be to close the fistula and preserve anal continence. The traditional surgical fistula closing techniques often show disappointing results. Today, a collagen plug for fistula treatment is commercially available. The mounting of this plug is technically easy and less invasive than the traditional closure of the fistula by making a lid of anal mucosa (advancement flap). The purpose of this study is to determine whether the outcome of anal fistula repair with a collagen plug is comparable to that of repair by a mucosal advancement flap, with regard to healing of fistula, anal continence and pain. Plug treatment has so far shown promising results, but prospective, randomised controlled trials are needed.
