Perianal Abscesses

A perianal space abscess is a painful collection of pus that occurs in the tissues around the anus. This condition can arise from infections or blockages in the glands located near the anus.

Anatomy

Structure

The perianal area includes several key structures:

• Anus: The opening at the end of the digestive tract.
• Rectum: The part of the intestine just above the anus.
• Perianal glands: Small glands located around the anus that can become blocked and infected.

Blood Supply

The blood supply to the perianal region comes primarily from branches of the internal pudendal artery, which is a branch of the internal iliac artery.

Nerve Supply

The area is innervated by branches of the pudendal nerve, which provides sensation and motor function to the anal region.

Types of Perianal Abscesses

1. Ischiorectal Abscess: Located in the space between the rectum and the ischium.
2. Intersphincteric Abscess: Located between the internal and external anal sphincters.
3. Supralevator Abscess: Above the levator ani muscle.
4. Perianal Abscess: Directly adjacent to the anal opening.

Causes

Here are 20 potential causes of perianal space abscesses:

1. Infection of anal glands
2. Fistulas (abnormal connections between organs)
3. Inflammatory bowel diseases (like Crohn’s disease)
4. Anal trauma (such as from hard stools)
5. Skin infections (like cellulitis)
6. Bacterial infections
7. Sexually transmitted infections
8. Poor hygiene
9. Anal fissures
10. Chronic constipation
11. Diabetes (increased risk of infections)

13. Tumors in the anal area
14. Radiation therapy (causing tissue damage)
15. Surgical complications (post-anal surgery)
16. Hemorrhoids (that become infected)
17. Pilonidal cysts (infected cysts near the tailbone)
18. Cysts (blocking glands)
19. Obesity (increasing risk of skin infections)
20. Anal sex (increased risk of trauma or infection)

9. Anoscopy (using a camera to look inside the anal canal)
10. Fistulography (imaging of fistulas)
11. Laparoscopy (if internal issues are suspected)
12. Complete blood count (CBC) (to check for signs of infection)
13. Urinalysis (to rule out urinary issues)
14. Stool tests (to identify inflammatory bowel disease)
15. Biopsy (if tumors are suspected)
16. Blood cultures (to check for systemic infections)
17. Proctoscopy (to examine the anal canal)
18. Imaging for associated conditions (like Crohn’s disease)
19. Nerve conduction studies (if nerve damage is suspected)
20. Electromyography (to assess anal sphincter function)
