Fistula

A fistula is a pathological formation that connects two different cavities or tissues. The occurrence of a fistula can be due to various reasons, including trauma, infection, inflammatory processes and some surgical interventions. The appearance of a fistula is accompanied by pain, bleeding and an unpleasant odor. Fistulas are an indication for surgery to stop the spread of infection.

There are many types of fistulas. They can occur in any part of the body, but are most common in the skin, joints, genitourinary system and abdomen. The most common are odontogenic (dental), postoperative and carcinomatous fistulas. Treatment of fistulas can be complex and depends on the type and severity of the lesion. Typically, fistulas require surgery, which involves removing the affected tissue or debridement of the cavity connected to the outside world. Antibiotics, anti-inflammatories, and physical therapy may also be used. In some cases, fistulas heal on their own.
