Middle rectal valve hemorrhoids are a type of internal hemorrhoid that develops near the middle rectal valve, an internal structure in the rectum. This detailed guide covers everything you need to know about the anatomy, types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, preventions, and more related to middle rectal valve hemorrhoids.
Anatomy of the Middle Rectal Valve & Hemorrhoids
1. Structure:
- The middle rectal valve is one of three horizontal folds within the rectum that supports stool retention.
- It helps control the passage of stool and gas through the rectum.
2. Blood Supply:
- Blood supply to this area comes primarily from the superior rectal artery, middle rectal artery, and inferior rectal artery.
- The venous drainage is via the superior rectal vein, which connects to the hemorrhoidal venous plexus, a common site for hemorrhoid formation.
3. Nerve Supply:
- The rectal nerves supply the rectal valve area, which carry sensations like pain and pressure.
- The middle rectal valve has both autonomic (involuntary) and somatic (voluntary) nerve fibers, contributing to bowel movement control.
Types of Hemorrhoids
Hemorrhoids are swollen veins in the rectum and anus. They can be classified into:
- Internal Hemorrhoids: Develop inside the rectum, often painless but can bleed.
- External Hemorrhoids: Located under the skin around the anus, can be painful.
- Thrombosed Hemorrhoids: Occur when a blood clot forms inside hemorrhoidal veins.
- Prolapsed Hemorrhoids: Internal hemorrhoids that bulge out of the anus.
Middle rectal valve hemorrhoids fall under the category of internal hemorrhoids.
