An anal fistula can occur after surgery to drain an anal abscess. In some cases, an anal fistula causes persistent drainage.

In other cases, where the outside of the channel opening closes, the result may be recurrent anal abscesses. The only cure for an anal fistula is surgery.

Video Assisted Anal Fistula Treatment

Video-assisted anal fistula treatment (VAAFT) is a novel minimally invasive and sphincter-saving technique for treating complex fistulas. Karl Storz Video Equipment is used. Key steps are visualization of the fistula tract using the fistuloscope, correct localization of the internal fistula opening under direct vision, endoscopic treatment of the fistula and closure of the internal opening using a stapler or cutaneous-mucosal flap. Diagnostic fistuloscopy under irrigation is followed by an operative phase of fulguration of the fistula tract, closure of the internal opening and suture reinforcement with fibrin thrombin glue.

The main feature of the VAAFT technique is that the procedure is performed entirely under direct endoluminal vision. With this approach, the internal opening can be found in 82.6% of cases. Moreover, fistuloscopy helps to identify any possible secondary tracts or chronic abscesses. The VAAFT technique is sphincter-saving, and the surgical wounds are extremely small.
