Middle Rectal Valve Cancer

The middle rectal valve is located in the rectum, which is the final section of the large intestine. The rectum is where waste (stool) is stored before it exits the body through the anus. The rectal valve itself helps control the movement of waste as it passes through the rectum.

• Structure: The rectal valve is made up of muscular tissue. It assists in regulating the passage of stool.
• Blood Supply: The rectal valve is supplied with blood by the superior, middle, and inferior rectal arteries. These arteries ensure the rectal tissues receive enough oxygen and nutrients.
• Nerve Supply: The autonomic nervous system, particularly the inferior hypogastric plexus, controls the rectum and its valves.

Types of Middle Rectal Valve Cancer

Middle rectal valve cancer is a type of colorectal cancer. The most common types are:

1. Adenocarcinoma – cancer that starts in mucus-secreting glands.
2. Squamous cell carcinoma – starts in the flat cells lining the rectum.
3. Neuroendocrine tumors – cancer that affects the neuroendocrine cells.
4. Carcinoid tumors – slow-growing cancers that can affect the rectal area.
5. Lymphoma – cancer that starts in the lymphatic system.
6. Sarcoma – rare cancer that affects the connective tissue in the rectal area.
