Duodenum Muscular Layer Stenosis is a medical condition where the muscular layer of the duodenum, the first part of the small intestine just beyond the stomach, becomes narrowed. This narrowing, known as stenosis, can impede the normal passage of food and digestive juices, leading to various digestive issues.
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:
- Superior (first) part
- Descending (second) part
- Horizontal (third) part
- 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:
- Congenital Stenosis: Present at birth due to developmental anomalies.
- Acquired Stenosis: Develops later due to diseases or injuries.
- Benign Stenosis: Non-cancerous causes like scarring or inflammation.
- Malignant Stenosis: Caused by cancers affecting the duodenum.
Causes of Duodenal Stenosis
Duodenal stenosis can result from various factors. Here are 20 common causes:
- Congenital Defects: Malformations present at birth.
