A fistula is a tunnel-like structure that connects two areas of tissue. It is most commonly found in the skin, but can also form between internal organs. Fistulas can be caused by injury, infection, or medical conditions such as Crohn’s disease or diverticulitis.
Symptoms of a Fistula
The most common symptom of a fistula is an opening in the skin, which may be tender, red, or swollen. Other symptoms may include drainage of pus or blood, pain, fever, and chills.
Diagnosis of a Fistula
A doctor may diagnose a fistula based on physical examination and medical history. They may also order imaging tests such as an X-ray, CT scan, or MRI to confirm the diagnosis.
Treatment of a Fistula
Treatment for a fistula will depend on the cause and severity. If the fistula is caused by an infection, antibiotics may be prescribed. Surgery may be necessary if the fistula is large or the infection is severe. In some cases, the fistula may heal on its own.
