An anal fistula usually lasts until it is surgically removed.  One of its treatment we used is VAAFT.

• VAAFT ( Video- Assisted Anal Fistula Treatment)
• In VAAFT, a fistulascope is inserted through the external opening and the whole tract is visualized on camera. The internal opening is localized through the endoscope while visualizing the ano-rectum from outside. After this, two stitches are taken through the internal opening so as to isolate the internal opening. After this, the fistula tract is cauterized with a monopolar cautery electrode so as to coagulate (burn) the fistula mucosa (lining) from internal opening to the external opening. The necrotic burnt tissue is taken out with the help of a brush and forceps. After this, the internal opening is lifted with the help of two stitches taken earlier and closed with a linear cutting Stapler which closes the tract at the level of the internal opening.
