Rectal Prolapse Images and Medical Diagrams

These educational rectal prolapse images and medical illustrations explain how the rectum can descend, what an external prolapse may look like, and how specialists evaluate and treat the condition.

Pictures can help patients understand anatomy, but a photograph cannot reliably distinguish rectal prolapse from prolapsing hemorrhoids, mucosal prolapse, or another anorectal condition. A medical examination is the safest way to confirm the diagnosis.

What Does Rectal Prolapse Look Like?

External or full-thickness rectal prolapse may appear as a red or pink circular segment of tissue protruding through the anus. The surface often has concentric folds or rings. It may appear during a bowel movement and return inside afterward, require gentle manual reduction, or remain outside in more advanced cases.

Prolapsing hemorrhoids can also produce protruding tissue, but they arise from the anal canal and often form separate columns or lumps rather than the circular folds typical of full-thickness rectal prolapse. See the detailed comparison of rectal prolapse versus hemorrhoids.

Do not rely on online images for self-diagnosis, especially when bleeding, severe pain, or a new lump is present.


Rectal Prolapse Overview Diagram

Rectal prolapse develops when the normal support structures of the rectum weaken, allowing rectal tissue to descend or protrude through the anus.

Rectal prolapse occurs when the rectum loses its normal support and descends. The term may describe:

  • Internal rectal prolapse: the rectum folds inward but does not extend outside the anus
  • Mucosal prolapse: only the inner lining protrudes
  • Full-thickness external prolapse: the entire rectal wall protrudes through the anus

Rectal Prolapse Symptoms Diagram

Symptoms of rectal prolapse may include protruding tissue, rectal fullness, bleeding, mucus discharge, constipation, incomplete evacuation, or stool leakage.

Symptoms vary with the type and severity of prolapse. Patients may notice:

  • Tissue protruding from the anus
  • Rectal pressure or a sensation that something is falling out
  • Mucus drainage or moisture
  • Rectal bleeding or irritation
  • Constipation, straining, or incomplete emptying
  • Stool leakage or reduced control of gas

The dedicated rectal prolapse symptoms guide explains what prolapse may feel like, how symptoms can progress, and which warning signs need prompt care.


Diagnostic and Surgical Procedure Diagram

Rectal prolapse evaluation may include anorectal examination, defecography, anorectal manometry, and surgical repair depending on the severity of symptoms.

Evaluation and treatment may involve:

  • Anorectal examination: an office assessment, sometimes while the patient strains
  • Defecography: X-ray or MRI imaging that shows the rectum and pelvic floor during evacuation
  • Anorectal manometry: testing of anal and rectal muscle function and reflexes
  • Colonoscopy: evaluation of the colon when indicated by bleeding, screening needs, or surgical planning
  • Rectopexy: an abdominal operation that returns and secures the rectum within the pelvis
  • Perineal repair: surgery performed through the anus and perineum in selected patients

When Rectal Prolapse Needs Urgent Evaluation

Most rectal prolapse develops gradually, but urgent medical evaluation is appropriate when:

  • Prolapsed tissue cannot be returned inside
  • The tissue becomes dark, dusky, purple, gray, or black
  • Severe or rapidly worsening pain develops
  • Swelling increases quickly
  • Heavy or continuous bleeding occurs
  • Fever, fainting, or marked weakness is present

These findings can indicate trapped tissue or impaired blood supply. Read when rectal prolapse may be an emergency.
