Middle Rectal Valve Ulcers

Structure

• The valve is formed by a crescent-shaped fold of mucosal tissue.
• It extends partway into the rectal cavity, functioning like a “shelf” to help control stool flow and maintain continence.

Blood Supply

• Blood supply to the rectal valves comes from the superior, middle, and inferior rectal arteries?.
• The middle rectal artery? specifically supplies the middle rectal valve and is a branch of the internal iliac artery.

Nerve Supply

• The rectal valves, including the middle one, receive nerve signals from the autonomic nervous system.
• Sympathetic nerves (inhibit movements) and parasympathetic nerves (stimulate movements) are involved in their innervation, helping control bowel movements.

Types of Middle Rectal Valve Ulcers

Middle rectal valve ulcers can be categorized based on their severity and underlying cause:

• Acute? ulcers: Sudden onset?, usually due to trauma? or injury.
• Chronic? ulcers: Long-standing ulcers often related to conditions like Crohn’s disease.
• Ischemic ulcers: Caused by reduced blood flow to the rectum.
• Inflammatory ulcers: Result from conditions like ulcerative colitis? or Crohn’s disease.
• Infectious ulcers: Caused by bacterial?, viral?, or parasitic infections.
• Radiation-induced ulcers: Result from radiation therapy? in the pelvic area.

Causes of Middle Rectal Valve Ulcers

1. Chronic constipation? (straining causes mucosal damage)
2. Crohn’s disease? (inflammatory bowel disease?)
3. Ulcerative? colitis? (inflammation? of the colon? and rectum)

5. Rectal trauma or injury
6. Radiation therapy (for cancers near the rectum)
7. Bacterial infections (e.g., E. coli)
8. Viral infections (e.g., cytomegalovirus)
9. Parasitic infections (e.g., amoebiasis)
10. Rectal prolapse (rectal tissue protrusion)
11. Anal fissures (small tears in the rectal lining)
12. Diverticulitis? (inflammation of diverticula in the colon)
13. Malignancy or tumors
14. Fecal impaction (hardened stool blocking the rectum)
15. Chronic diarrhea?
16. Rectal polyps (abnormal growths)
17. Hemorrhoids? (swollen veins? in the rectum)
18. Autoimmune? disorders (e.g., lupus?)
