Duodenal Stenosis

Anatomy? of the Duodenum

The duodenum is the first segment of the small intestine, located just below the stomach. It plays a crucial role in digestion by receiving partially digested food (chyme) from the stomach and digestive enzymes from the pancreas? and bile from the liver?. The duodenum is divided into four parts:

1. Superior (first) part
2. Descending (second) part
3. Horizontal (third) part
4. Ascending (fourth) part

The muscular layer of the duodenum is essential for peristalsis—the wave-like contractions that move food through the digestive tract.

Types of Duodenal Stenosis

Duodenal stenosis can be categorized based on its location, cause, and severity:

1. Congenital? Stenosis: Present at birth due to developmental anomalies.
2. Acquired Stenosis: Develops later due to diseases or injuries.
3. Benign? Stenosis: Non-cancerous causes like scarring or inflammation?.
4. Malignant? Stenosis: Caused by cancers affecting the duodenum.

Causes of Duodenal Stenosis

Duodenal stenosis can result from various factors. Here are 20 common causes:

1. Congenital Defects: Malformations present at birth.
2. Peptic Ulcers: Sores that can cause scarring.
3. Inflammatory Bowel Disease?: Conditions like Crohn’s disease?.
4. Cancer: Duodenal tumors or pancreatic cancer.

14. Gastric Bypass Surgery: Complications from weight loss? surgery.
15. Foreign Bodies: Ingestion of objects causing blockage.
16. Endoscopic Procedures: Complications from endoscopy?.
