Anal Fistula is an abnormal passage (communication) between the interior of the anal canal or rectum and the skin surface around the anus. Rarely, the fistula may communicate from anus (rectum) to Vagina (Recto-Vaginal Fistula), Urinary Bladder (Recto-Vesical Fistula), Urethera (Recto-Uretheral Fistula) or other pelvic structures, including the bowel.


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.
