Anoscopy uses a short 7 cm scope to examine the anal canal for internal haemorrhoids and bleeding points. Takes 1–2 minutes, causes pressure but not significant pain.
Anoscopy: The Standard Tool for Internal Piles Diagnosis
An anoscope is a short (7 cm), hollow, lighted instrument used to examine the anal canal. It is the most commonly used instrument for diagnosing and grading internal haemorrhoids in outpatient proctology clinics.
How Anoscopy Differs from Proctoscopy
| Feature | Anoscopy | Proctoscopy | |---|---|---| | Length | 7 cm | 15 cm | | Visualises | Anal canal | Anal canal + lower rectum | | Best for | Grade I–III piles, fissure | All anorectal conditions | | Time | 1–2 minutes | 2–5 minutes |
Both are appropriate for haemorrhoid examination — your doctor chooses based on clinical need.
The Anoscopy Procedure
1. Patient placed in left lateral position 2. Anoscope lubricated and gently inserted 3. Inner obturator removed — provides direct view of anal canal 4. Internal haemorrhoids visualised as vascular cushions 5. Patient may be asked to strain gently — shows degree of prolapse 6. Scope withdrawn slowly 7. Procedure complete
**Total time:** 1–3 minutes. **Sensation:** Pressure/fullness, similar to urge to defecate. Not significantly painful for most patients.
What the Doctor Looks for During Anoscopy
- Size and location of internal haemorrhoidal columns (typically at 3, 7 and 11 o'clock positions)
- Degree of engorgement and prolapse
- Active bleeding points
- Mucosal condition (inflammation, polyps, proctitis)
- Grade assignment based on prolapse behaviour
Frequently Asked Questions
**Q: Do I need to do anything to prepare for anoscopy?** A: No special preparation. You can eat and drink normally. The procedure is done in the same visit as your consultation.
**Q: Will I need anoscopy every visit?** A: No — anoscopy is primarily diagnostic. Once grade is confirmed, follow-up visits typically use clinical examination and symptom assessment rather than repeated instrumentation.
