VAAFT (Video Assisted Anal Fistula Treatment) is a minimally invasive surgical procedure used to treat anal fistulas. An anal fistula is a small tunnel that forms between the end of the bowel and the skin near the anus. In VAAFT, a small video camera (endoscope) is inserted through the anus to visualize the fistula and guide the surgery. The fistula is then sealed off using a combination of techniques such as laser, diathermy or other methods, and the patient is usually discharged the same day of the surgery.
