Ano-rectal pathology

Anorectal conditions are common and, if identified during assessment, require referral to a medical practitioner.

Common conditions experienced include:

  • Haemorrhoids - vascular structures in the anal canal which, in their normal state help to control stools. They can swell, becoming painful and inflamed.
  • Anorectal fistula - an abnormal connection between the anal canal and the perianal skin. The internal opening is inside the anorectal lumen. The external opening is on the perianal skin surface.
  • Anal fissure - a tear in the opening of the anus.
  • Rectal prolapse - a protrusion of either the rectal mucosa or the entire wall of the rectum. Rectal prolapses occur either with bowel movements or independently.
