Which feature is associated with a simple fistula?

• A. Abscess formation with multiple organ involvement
• B. Short, direct tract
• C. Open into base of a disrupted wound
• D. “Easy” fistula

Answer: (B)

A simple fistula is best defined by its single, straight tract from the internal source to the skin, with little to no branching. That direct, short course makes the fistula relatively easy to manage because there’s only one path for drainage and healing, and fewer compartments for infection or tissue distortion. The option describing a short, direct tract matches this pattern exactly, which is why it’s the best choice for a simple fistula. Other features point toward more complex fistulas. Abscess formation with involvement of multiple organs indicates multiple tracts and greater inflammation, which complicates care. Opening into the base of a disrupted wound suggests a more intricate wound environment with possible additional tracts or tissue damage. Calling it an “easy” fistula isn’t a standard descriptor and doesn’t define tract pattern. In practice, the simplicity or complexity is driven by the tract anatomy rather than just perceived ease.
