What is an anal fistula? Why do anal fistulas occur?
Anal fistula is an abnormal connection between anal canal and skin. There are a number of causes for anal fistulas, the most common being infection in the glands close to the anal canal.
What are the typical symptoms of an anal fistula?
The most common symptom of anal fistula is perianal discharge. Quite often, the first presentation of anal fistula is an anal abscess.
How are anal fistulas diagnosed? Why is early diagnosis important?
The diagnosis of anal fistula is based on clinical and radiological assessment. Clinical assessment can be performed in clinic and under anaesthesia. Radiological assessment is often necessary in recurrent or complex fistulas.
Delayed diagnosis of anal fistula can result in conversion of simple fistulas into complex anal fistulas.
What are the available treatment options for anal fistulas?
There are a number of treatment options for anal fistulas, including placement of setons, laying open of the fistula tract, ligation of the fistula tract, fibrin plug, video assisted treatment and treatment using laser or radiofrequency. Depending upon the severity and complexity of the fistula, the most appropriate form of treatment will vary.
What are the potential complications and long-term consequences of anal fistulas?
The main complication of fistula treatment is incontinence and recurrence. Often the ideal management of a fistula is to maintain a balance between fistula recurrence and faecal incontinence. The newer treatments, such as video assisted treatment and use of laser or radiofrequency, have a higher chance of recurrence but a lower chance of incontinence.
