As a physician, can I perform a self‑examination of my perianal skin and anus before my appointment with a colorectal surgeon?

Can You Perform a Self-Examination of Your Perianal Area Before Your Colorectal Surgeon Appointment?

Yes, you can perform a visual inspection of your perianal skin, but you should not attempt a digital rectal examination on yourself—wait for your colorectal surgeon to perform a proper examination.

What You Can Safely Do

You can perform a careful visual inspection of your perianal area before your appointment. This is actually consistent with standard clinical practice, as guidelines emphasize that inspection is a fundamental component of anorectal evaluation 1, 2.

Specific Steps for Self-Inspection:

• Position yourself using a mirror in good lighting (similar to the left lateral position used clinically)

• Look for visible abnormalities including:

  • Skin tags or hemorrhoids
  • Anal fissures (tears in the skin)
  • Perianal swelling, redness, or cellulitis
  • Discharge or pus from external openings
  • Anorectal deformities or surgical scars
  • Signs of prolapse or patulous (gaping) opening
  • Perianal skin changes suggesting Crohn's disease 1

• Observe during simulated defecation (bearing down) to check for:

  • Descent of the perineum
  • Any prolapsing tissue
  • Abnormal opening of the anal verge 2

What You Should NOT Do

Do not perform digital rectal examination on yourself. Here's why:

1. Technical limitations: A proper digital rectal examination requires specific positioning and technique that cannot be adequately performed on oneself 1, 2

2. Critical assessment components you cannot evaluate on yourself:

   • Resting sphincter tone and squeeze pressure
   • Puborectalis muscle contraction
   • Presence of tender, indurated areas above the anorectal ring (suggesting deeper abscesses)
   • Proper assessment of masses or strictures
   • Evaluation for rectocele 2, 3

3. Safety concerns: If you have a retained foreign body or sharp object, digital examination should only be performed after imaging to prevent injury 1

4. Pain may require sedation: In cases of anorectal abscesses or severe pathology, proper examination may require sedation or anesthesia, which obviously cannot be self-administered 1

Common Pitfalls to Avoid

• Don't delay your appointment thinking self-examination is sufficient. Deeper abscesses (intersphincteric, supralevator) can be challenging to diagnose even with proper examination and may require imaging 1

• Don't miss red flags: If you notice severe pain, fever, swelling, or discharge, these may indicate an abscess requiring urgent drainage—don't wait for your scheduled appointment 1

• Remember symptoms can be subtle: In immunosuppressed patients, diabetics, or elderly individuals, symptoms may be diminished despite serious pathology 1

What to Document for Your Surgeon

Note any findings from your visual inspection:

• Location and appearance of any lesions
• Presence of discharge or bleeding
• Associated symptoms (pain, fever, difficulty with bowel movements)
• Timing and progression of symptoms
• Any history of inflammatory bowel disease, previous anorectal surgery, or immunosuppression 1, 3

Your colorectal surgeon will perform a complete anorectal examination including digital rectal examination, and potentially anoscopy or examination under anesthesia if needed 1, 4, 3. This comprehensive evaluation by a specialist is essential for accurate diagnosis and appropriate management.
