Anal Canal Piles

Anatomy of the Anal Canal and Hemorrhoids

The anal canal is the final part of the digestive system, measuring about 4 cm in length. It connects the rectum to the outside of the body and allows waste (stool) to exit during a bowel movement.

Structure

The anal canal consists of:

• Internal anal sphincter: This muscle remains tight to keep stool inside until you’re ready to pass it.
• External anal sphincter: This muscle helps control the release of stool.
• Mucosal lining: The inside is lined with tissue that helps ease the stool’s passage.
• Blood vessels: Veins surround the anal canal and can become swollen, forming piles (hemorrhoids).

Blood Supply

The anal canal gets its blood from:

• Superior rectal artery
• Middle rectal artery
• Inferior rectal artery

Nerve Supply

The anal canal is innervated by:

• Somatic nerves for the external area (voluntary control).
• Autonomic nerves for the internal area (involuntary control).

Types of Hemorrhoids (Piles)

There are two main types of hemorrhoids:

1. Internal hemorrhoids: These occur inside the rectum and are usually painless, though they can cause bleeding.
2. External hemorrhoids: These occur under the skin around the anus and can cause pain?, swelling?, and irritation.

Another subtype includes:

• Thrombosed hemorrhoids: These are external hemorrhoids that have developed a blood clot, causing severe pain? and swelling?.

Causes of Hemorrhoids

Diagnostic Tests for Hemorrhoids

Doctors use the following tests to diagnose hemorrhoids:

1. Physical exam (visual inspection)
2. Digital rectal exam (finger examination)
3. Anoscopy (viewing the anal canal)
4. Proctoscopy (viewing the rectum)
5. Colonoscopy (examining the colon for other issues)
6. Sigmoidoscopy (examining the lower colon)
7. Ultrasound? (to check blood flow)
8. MRI (for detailed images of tissues)
9. CT scan? (for cross-sectional images)
10. Complete blood count (CBC)
11. Fecal occult blood test (FOBT)
12. Stool sample test
13. Hemorrhoid grading (from I to IV based on severity)
14. Anorectal manometry (measuring muscle tone)
15. Endoscopy? (using a small camera)
16. Pelvic MRI
17. Rectal biopsy? (in rare cases)
18. Doppler ultrasound? (to assess blood flow in hemorrhoidal vessels)
19. Defecography (an X-ray? to study bowel function)
