Abstract
|
|
|
|
Usually a patient has an anal fistula, which has an internal (primary) opening, an external (secondary) opening, and a tract connecting the two. Uncommonly, the external openings are more than one but mostly lead to a single internal opening. Rarely the multiple external openings lead to more than one internal opening. Each internal opening, its corresponding tract(s), and its external opening(s) are considered as a separate (independent) fistula. The patient in question had three external openings leading to three separate internal openings. When multiple external openings are present, injection of a dye or hydrogen peroxide to identify the internal openings must be considered.
