During a VAAFT procedure, a small camera is inserted into the anal canal to visualize the fistula and surrounding tissue. A small incision is made at the external opening of the fistula and the internal opening is identified using the camera. A specialized instrument is then used to remove the lining of the fistula and seal the tract with a special glue.

VAAFT is a relatively quick and painless procedure that can be performed under local anesthesia on an outpatient basis. It offers several advantages over traditional fistula surgery, including a shorter recovery time, less pain, and a lower risk of complications such as incontinence and infection. However, VAAFT may not be suitable for all types of anal fistulas, and some people may still require traditional surgery. It is important for people with anal fistulas to consult with a healthcare provider to determine the best treatment option for their individual needs.
