What happened to the duodenal eminence?

Duodenal swelling is usually associated with trauma or surgery, congenital abnormalities, and tumors.

1. Trauma or surgery

may cause scar tissue in the duodenum due to trauma or surgery, which may lead to local swelling.

2. Congenital abnormalities

such as duodenal diverticulum, which is a congenital mucosal protrusion that usually has no obvious symptoms, but may lead to complications in some cases.

3. Tumors

include benign tumors and malignant tumors, which can lead to local thickening of the intestinal wall, and as the tumor grows, it can lead to local swelling.
