A sigmoid mesocolon mass refers to an abnormal growth located in the sigmoid mesocolon, which is the connective tissue supporting the sigmoid colon—a part of the large intestine. Understanding sigmoid mesocolon masses is crucial for early detection and effective treatment. This guide provides detailed information on the anatomy, types, causes, symptoms, diagnostic tests, treatments, prevention, and frequently asked questions about sigmoid mesocolon masses.
Anatomy of the Sigmoid Mesocolon
Structure
The sigmoid mesocolon is a fold of the peritoneum (a thin layer of tissue) that attaches the sigmoid colon to the back wall of the abdomen. It contains blood vessels, nerves, and lymphatics that supply the sigmoid colon.
Blood Supply
- Superior Mesenteric Artery (SMA): Supplies blood to the midgut, including the distal part of the transverse colon and the ascending colon.
- Inferior Mesenteric Artery (IMA): Specifically provides blood to the sigmoid colon and upper part of the rectum through its branches:
- Left Colic Artery
- Sigmoid Arteries
Nerve Supply
- Autonomic Nervous System: Controls involuntary functions.
- Sympathetic Fibers: Originate from the spinal cord and provide pain sensation and control blood flow.
- Parasympathetic Fibers: Enhance digestive processes.
Types of Sigmoid Mesocolon Masses
- Benign Tumors:
- Lipomas
- Leiomyomas
- Fibromas
- Malignant Tumors:
- Adenocarcinoma (colon cancer)
