Rectal Examination: A Step-by-Step Guide

Introduction

A rectal examination is a crucial component of a comprehensive physical examination, especially for older adults. It allows for the assessment of the rectum, anus, and prostate gland, and can help identify various conditions. This guide will outline the steps involved in performing a rectal examination, explain the rationale behind each step, and discuss potential findings, including those associated with acute prostatitis and benign prostatic hypertrophy (BPH).

Steps Involved in Rectal Examination

1. Preparation:

   • Ensure privacy: Conduct the examination in a private setting, such as an examination room.
   • Explain the procedure: Clearly explain the procedure to the patient, addressing any concerns or questions they may have.
   • Position the patient: The patient can be positioned in the left lateral decubitus position or standing, with their feet slightly apart.

2. Inspection:

   • Inspect the perianal area: Examine the skin around the anus for any lesions, fissures, hemorrhoids, or signs of inflammation.
   • Assess anal tone: Observe the anal sphincter for any involuntary contractions or relaxation.

1. Digital Examination:

   • Don gloves and lubricant: Wear disposable gloves and apply lubricant to your index finger.
   • Insert finger: Gently insert your lubricated index finger into the anus.
   • Palpate the rectum: Palpate the rectal wall for any masses, polyps, or abnormalities.
   • Assess rectal tone: Evaluate the tone of the internal and external anal sphincters.
   • Palpate the prostate gland: In males, palpate the prostate gland through the anterior rectal wall. Assess its size, shape, consistency, and tenderness.

Rationale for Each Step

• Inspection: Visual examination allows for the identification of external abnormalities that may indicate underlying conditions.
• Digital Examination: Palpation of the rectum and prostate gland can help detect abnormalities such as masses, polyps, or inflammation. Assessing the anal sphincters provides information about their function and potential abnormalities.

Findings During Rectal Sphincter Assessment

• Normal: The anal sphincters should contract normally when the finger is inserted and relax when the finger is withdrawn.
• Incontinence: If the sphincters are weak or damaged, the patient may experience fecal incontinence.
• Spasticity: Increased tone of the sphincters can lead to constipation or difficulty passing stools.

Acute Prostatitis vs. Benign Prostatic Hypertrophy

• Acute Prostatitis:
  • Rectal examination: The prostate gland will feel enlarged, tender, and warm to the touch.
  • Other findings: Fever, chills, urinary frequency, urgency, dysuria, and pelvic pain are common symptoms.
• Benign Prostatic Hypertrophy:
  • Rectal examination: The prostate gland will feel enlarged, smooth, and rubbery.
  • Other findings: Urinary frequency, nocturia, weak urinary stream, and hesitancy are common symptoms.

Physical Examination Findings

• Acute Prostatitis: In addition to the rectal examination findings, physical examination may reveal fever, tachycardia, and abdominal tenderness.
• Benign Prostatic Hypertrophy: Physical examination may also reveal a distended bladder or a palpable prostate gland.

Conclusion

A rectal examination is a valuable diagnostic tool for assessing the rectum, anus, and prostate gland. By understanding the steps involved, the rationale behind each step, and the potential findings, healthcare providers can effectively conduct this examination and identify any underlying conditions.
