Sigmoid colon masses are abnormal growths located in the sigmoid part of the large intestine. Understanding their anatomy, causes, symptoms, diagnostics, treatments, and prevention can help in early detection and effective management. This guide provides detailed information in simple language to enhance your knowledge and assist in recognizing when to seek medical help.
Anatomy of the Sigmoid Colon
Structure
The sigmoid colon is the S-shaped last part of the large intestine, connecting the descending colon to the rectum. It plays a crucial role in storing fecal waste before it moves to the rectum for elimination.
Blood Supply
The sigmoid colon receives blood primarily from the sigmoid arteries, which branch off the inferior mesenteric artery. Adequate blood flow is essential for its function and health.
Nerve Supply
Nerves in the sigmoid colon come from the autonomic nervous system, specifically the pelvic splanchnic nerves. These nerves help regulate muscle contractions and secretions necessary for bowel movements.
Types of Sigmoid Colon Masses
- Benign Tumors
- Polyps: Small, non-cancerous growths that can develop into cancer over time.
- Leiomyomas: Smooth muscle tumors.
- Lipomas: Fatty tissue tumors.
- Malignant Tumors
- Adenocarcinoma: The most common type of colon cancer originating from glandular cells.
- Lymphoma: Cancer of the lymphatic system affecting the colon.
- Sarcoma: Cancer arising from connective tissues.
- Other Masses
- Diverticula: Pouches that can form and become inflamed (diverticulitis).
- Abscesses: Pockets of infection.
- Fibromas: Fibrous tissue tumors.
