A sigmoid mesocolon fistula is an abnormal connection that forms between the sigmoid colon (a part of the large intestine) and another organ or the skin. This condition can cause various health problems and requires medical attention. Understanding what sigmoid mesocolon fistulas are, their causes, symptoms, and treatment options can help you recognize and seek help if needed.
Anatomy of the Sigmoid Mesocolon
Structure
The sigmoid mesocolon is a fold of tissue that attaches the sigmoid colon to the back wall of the abdomen. The sigmoid colon is the S-shaped final part of the large intestine, leading to the rectum. The mesocolon provides support and contains blood vessels, nerves, and lymphatics that supply the sigmoid colon.
Blood Supply
Blood to the sigmoid colon is primarily supplied by the sigmoid arteries, branches of the inferior mesenteric artery. These arteries ensure that the sigmoid colon receives the necessary oxygen and nutrients to function properly.
Nerve Supply
The nervous system in the sigmoid mesocolon controls the movement and function of the sigmoid colon. It helps regulate the contraction and relaxation of muscles to move waste through the intestines.
Types of Sigmoid Mesocolon Fistulas
Sigmoid mesocolon fistulas can be categorized based on their connections:
- Enteric Fistulas: Connect the sigmoid colon to another part of the intestine.
- Enterocutaneous Fistulas: Connect the sigmoid colon to the skin.
- Enterovesical Fistulas: Connect the sigmoid colon to the bladder.
- Enterovaginal Fistulas: Connect the sigmoid colon to the vagina.
- Enteroenteric Fistulas: Connect different sections of the intestines.
