What are abscesses and anal fistulas? Abnormal connections between the anal canal and skin-lined structures.

Anal abscesses and fistulas are painful conditions affecting the anal region. An abscess is a localized infection with an accumulation of pus, often resulting from the obstruction of an anal gland. When an abscess doesn’t heal properly, it can develop into an anal fistula, an abnormal tunnel between the infected gland and the skin near the anus. Both conditions can cause considerable discomfort, swelling and drainage. They are usually treated by surgery, which offers relief and prevents the recurrence of infection. Fistulas can also form between the bowel and the bladder or vagina, causing leakage of fecal matter from either organ.

What are the symptoms of abscesses and anal fistulas?

  • Pain
  • Swelling
  • Drainage of pus or fluid
  • Redness and irritation around the anal area
  • Recurrent infections
  • Fever (in severe cases)

Who do abscesses and anal fistulas affect?

People with conditions such as diverticular disease, Crohn’s disease or cancers of the gastrointestinal tract are more likely to develop fistulas, as these conditions can lead to the formation of tunnels or abnormal passages between the anal canal or rectum and surrounding tissues. In addition, infections, trauma, and certain sexually transmitted infections can also contribute to the development of fistulas. These abnormal connections can result from tissue erosion, inflammation or infection in the area concerned. Surgical treatment is often required to treat and manage fistulas.
