The rectum is the final part of the large intestine, which leads to the anus. The rectum can be divided into three sections: the upper, middle, and lower rectum. The middle rectum sits between the upper and lower rectum, approximately 5-10 cm above the anal opening.
- Structure: The rectum is a tube made up of multiple layers:
- Mucosa: The innermost layer that helps in absorbing water and nutrients.
- Submucosa: Contains blood vessels, nerves, and connective tissue.
- Muscle Layer: Contains circular and longitudinal muscles that push stool downwards.
- Serosa: The outer layer.
- Blood Supply: The middle rectum is primarily supplied by the middle rectal artery. The veins from the middle rectum drain into the middle rectal veins.
- Nerve Supply: Nerve supply comes from the pelvic splanchnic nerves and hypogastric plexus, which control bowel movements and sensations in the rectum.
Types of Middle Rectum Diseases
- Rectal Prolapse: Occurs when the rectum slips down into the anus.
- Rectal Cancer: Tumors that develop in the rectal walls.
- Rectal Polyps: Abnormal growths in the rectal lining.
- Proctitis: Inflammation of the rectum, often from infection or inflammatory bowel diseases.
- Hemorrhoids: Swollen blood vessels in the rectum, causing pain or bleeding.
- Diverticulitis: Inflammation or infection of small pouches that form in the rectum.
- Rectal Ulcers: Sores or ulcers that develop in the rectal lining.
- Fistulas: Abnormal connections between the rectum and other organs.
