Rectal and Anal Conditions

Rectal Prolapse

What is rectal prolapse?

A rectal prolapse is a condition in which the rectum protrudes through the anus. This is not a life threatening condition but it may be alarming for the sufferer. There are varying degrees of prolapse:

  • Incomplete prolapse - this is internal and therefore not visible from outside the anus
  • Mucosal prolapse - this involves only the inner lining of the rectum
  • Complete prolapse - protusion of the full thickness of the rectum

What causes a rectal prolapse?

The cause of rectal prolapse is largely unknown. Possible causes include

  • Excessive straining during defecation
  • Chronic constipation
  • Weak pelvic floor and anal sphincter muscles
  • Lack of fixation of the rectum to pelvis
  • Ageing process due to weakening of the ligaments supporting the rectum
What are the symptoms of rectal prolapse?
  • Protrusion of the bowel which generally occurs during defecation or when the intra abdominal pressure is increased either coughing or straining.
  • A feeling of an incomplete emptying of the rectum
  • Discomfort
  • Bleeding
  • Mucous discharge from the rectum
  • Incontinence or poor control of bowel motions
How will your doctor diagnose a rectal prolapse?
  • Your doctor may ask you to strain whilst in a sitting position, or ask you to go to the toilet to strain.
  • Your doctor may place a gloved finger in your rectum and ask you to squeeze your anus. This establishes anal pressure
  • Anal manometry -this is a test that measures if the muscles around the rectum are functioning normally.
  • Flexible sigmoidoscopy examination- this is a flexible telescope inserted through your anus into your rectum and sigmoid colon
  • Proctogram - an x-ray taken with contrast in the rectum

How is a rectal prolapse treated?

A prolapse may be treated with bulk laxatives in an attempt to reduce straining during bowel movement. However simple correction of these problems may not improve a prolapse once it has developed.

Surgical treatment for rectal prolapse is dependent on a number of factors:

  • Age
  • Physical condition
  • Extent of prolapse
Types of surgical procedures that your surgeon may discuss with you include:
  • Abdominal operations to fix the rectum in the pelvis.
  • Operations through the anus to tighten the area of rectum that has prolapsed.
