Patient Info: Anal Fistula and Lesions

Printable Version of This Topic

Fistula

Fistula is a false passage or tunnel usually from the lower end of the anal canal to the skin right next to it. It will not go away by itself and can be treated, in most cases, under local anesthetic in the clinic by de-roofing the tunnel and allowing it to heal from the inside out, which takes a few weeks. It is only painful if the post-operative wound is not kept clean and dry.

Anal Lesions

Anal lesions such as skin tags and hematomas (blood clots) are also removed under local in the clinic, but only if they bother the patient. This procedure takes about 3 minutes, but it requires the same care to keep the healing wound clean and dry.
