Sigmoid Colon Stenosis

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 wastes until they are ready to be expelled from the body.

Blood Supply

The sigmoid colon receives blood primarily from the sigmoid arteries?, branches of the inferior mesenteric artery?. Adequate blood flow is essential for the healthy functioning of the colon.

Nerve Supply

The sigmoid colon is innervated by the autonomic nervous system, which controls involuntary actions like muscle contractions for moving stool through the intestines.

Types of Sigmoid Colon Stenosis

1. Benign? Stenosis: Caused by non-cancerous conditions such as diverticulitis? or inflammatory bowel disease?.
2. Malignant? Stenosis: Resulting from cancerous growths, typically colon cancer, that narrow the sigmoid colon.
3. Congenital? Stenosis: A rare condition present from birth due to abnormal development of the colon.
4. Iatrogenic Stenosis: Occurs as a complication? from medical procedures or surgeries involving the colon.
