An anal fistula often results from a prior abscess that caused erosion of the muscular barriers between the internal cavity and the skin surface.
Causes of Anal Fistula:
- Bacterial infection of the glands in the anal canal
- Formation of a pus-filled abscess in the anal region
- Tuberculosis
- Cancer
- Crohn’s disease
- Sexually transmitted diseases, such as syphilis
- Surgical injury
Symptoms of Anal Fistula:
- Recurrent anal abscesses that return despite treatment
- Anal pain that intensifies during bowel movements; the pain is often throbbing, caused by internal pus accumulation
- Swelling in the anal area
- Traces of blood in the stool
- Discharge of blood or pus from an abnormal opening in the anal area; the patient may feel relief after the pus drains
Important Tips After Anal Fistula Surgery:
It is essential to maintain good hygiene and consume fiber-rich foods—such as vegetables and fruits—to facilitate easy bowel movements without causing complications in the anal canal. Laxatives may also be prescribed by the doctor to prevent constipation during the recovery period.
