Sigmoid mesocolon cancer is a type of cancer that affects the sigmoid colon and its surrounding tissues. This guide provides detailed information about its anatomy, types, causes, symptoms, diagnostic tests, treatments, medications, surgeries, prevention methods, when to see a doctor, and frequently asked questions. Written in simple language, this guide aims to enhance understanding and accessibility for everyone.
Sigmoid mesocolon cancer is a cancer that originates in the sigmoid colon, the S-shaped part of the large intestine closest to the rectum and anus. The mesocolon is the tissue that attaches the colon to the abdominal wall, supplying it with blood, nerves, and lymphatics. When cancer develops in this area, it can affect both the colon and the mesocolon.
Anatomy of the Sigmoid Mesocolon
Structure
The sigmoid colon is the final section of the large intestine, approximately 40 cm long, leading to the rectum. The mesocolon is a fold of the peritoneum that connects the sigmoid colon to the posterior abdominal wall, providing support and housing blood vessels, nerves, and lymphatics.
Blood Supply
- Superior Sigmoid Artery: Supplies the upper part of the sigmoid colon.
- Inferior Sigmoid Artery: Supplies the lower part of the sigmoid colon.
- Middle Colic Artery: Contributes to the blood supply.
Nerve Supply
- Autonomic Nervous System: Provides involuntary control over the colon’s movements.
- Enteric Nervous System: Manages local gut functions.
Types of Sigmoid Mesocolon Cancer
- Adenocarcinoma: The most common type, originating from glandular cells.
- Squamous Cell Carcinoma: Rare, arising from flat epithelial cells.
- Lymphoma: Cancer of the lymphatic system within the mesocolon.
- Sarcoma: Originates from connective tissues like muscles or fat.
- Metastatic Cancer: Cancer that has spread from another part of the body.
