Superior Part of Duodenum Stenosis

The duodenum is the first part of the small intestine. It’s where food passes after leaving the stomach. The superior part refers to the upper section of this area, which connects to the stomach.

Stenosis means narrowing. So, superior part of the duodenum stenosis is when the upper part of the duodenum becomes too narrow for food to pass through easily. This can lead to digestive problems, including pain, bloating, and vomiting.

Types of Duodenum Stenosis

1. Congenital stenosis – Present at birth.
2. Acquired stenosis – Develops later due to other health conditions.
3. Partial stenosis – The narrowing isn’t complete, so food can still pass, though slowly.
4. Complete stenosis – The narrowing is so severe that food cannot pass through.
5. Benign stenosis – Not cancerous; usually caused by scarring or ulcers.
6. Malignant stenosis – Caused by cancer in the duodenum or nearby organs.
7. Inflammatory stenosis – Related to chronic inflammation, such as Crohn’s disease.
8. Post-surgical stenosis – Stenosis that occurs after a surgery that involves the duodenum.
9. Traumatic stenosis – Caused by injury to the abdomen.
10. Ischemic stenosis – Narrowing due to lack of blood flow.
11. Anastomotic stenosis – Happens after surgery to connect two parts of the digestive tract.
12. Peptic stenosis – Resulting from severe peptic ulcers.
13. Radiation-induced stenosis – After radiation therapy in the abdominal area.
14. Vascular compression stenosis – Caused by blood vessels pressing on the duodenum.
15. Idiopathic stenosis – The cause is unknown.
16. Tumor-induced stenosis – Narrowing due to growth of tumors.
17. Fibrotic stenosis – Due to excessive tissue buildup, usually from chronic inflammation.
18. Chronic pancreatitis-induced stenosis – Chronic inflammation of the pancreas affecting nearby organs.
19. Parasitic stenosis – Caused by parasitic infections.
20. Chemical-induced stenosis – Due to ingestion of harmful substances.
