Inspection
Inspect the region for any signs that may be clinically relevant:
👉 Skin tags: can be associated with IBD
👉 Anal fistula: pus discharge from the fistulae, caused by perianal Crohn’s disease/diverticulitis/chronic anal abscess
👉 Anal fissure: anal canal tear due to constipation
👉 Skin excoriation: caused by haemorrhoids/constipation/faecal incontinence
👉 External bleeding: caused by anal cancer/external haemorrhoids/ brisk gastrointestinal bleeding
👉 External haemorrhoids: ‘lump’ located just inside the anus
Ask the patient coughs inspect for:
👉 Internal haemorrhoids: bluish, bulging vessels covered in mucosa
👉 Rectal prolapse: concentric rings of mucosa on a mass
Inflammatory Bowel Disease (IBD):
👉 IBD: blanket term encompassing disorders which cause the gastrointestinal tract (GIT) to become chronically inflamed.
👉 Crohn’s disease: IBD subtype, affects any part of the GIT, causes rectal bleeding, abscesses, more than one skin tag or perianal fistulas
👉 Ulcerative colitis: IBD subtype, affects rectum and colon, causes excess mucous and loose, stool with blood in it
Palpation
- Apply lubricant to the finger 👆 you will use for the examination
- Inform the patient you are ready to insert your finger 👆 into the anal canal
- Gently insert finger
- Male patients: asses the size, texture and symmetry of the prostate gland by palpating it anteriorly, identifying abnormalities:
- Prostate cancer: hard, asymmetrical and irregular prostate gland, may also be a nodule in one of the lobes which you can palpate
- Prostatitis: spongy, tender prostate gland
- Benign prostatic hypertrophy: smooth and enlarged prostate with no groove in the midline
- Assess the rectum by circularly rotating your finger 👆 360°
- Record 📏 the size, texture, location and any lumps
- Identify any hard stool indicative of constipation
- Identify any tenderness indicative of anal fissure/thrombosed internal haemorrhoids
- Ask the patient to exert pressure on your finger 👆 to allow you to assess the tone
- Reduced anal tone is caused by spinal cord pathology, IBD and prior surgery
- Remove your finger 👆 from the anus and inspect it
- Fresh red blood: indicates lower GI bleeding
- Dark sticky blood (melaena): indicates upper GI bleeding
- Excess mucous: indicates IBD
- Using paper towels, clean the patient
- Cover the patient and leave the room, explain they can now get dressed
- Dispose of equipment appropriately
- Wash hands ✋
Completion
- Thank patient
- Document the examination
- Summarise what the examination revealed ✍
Subsequent investigations
👉 Blood tests: for concerns about GI bleeding
👉 CT abdomen and pelvis: for concerns about lower GI malignancy
👉 Abdominal examination: for concerns about intra-abdominal pathology
👉 Flexible colonoscopy/sigmoidoscopy: for concerns about lower GI malignancy or bleeding
👉 Faecal occult blood test: for concerns about lower GI malignancy
Summary:
- Greet the patient and briefly explain the examination
- Prepare by washing your hands, putting on PPE, and asking patient to lie on their side with their knees at their chest
- Inspect the rectal area for any clinically relevant signs, and ask the patient to cough
- Palpate the rectum
- Complete the procedure by thanking the patient and giving them privacy to change
