Horizontal Duodenum Tumors

Anatomy of the Duodenum

Understanding the duodenum’s structure helps in comprehending where tumors can develop.

• Location: The duodenum is a C-shaped tube located just below the stomach.
• Sections: It has four parts:
  1. Superior (First) Part: Connects to the stomach.
  2. Descending (Second) Part: Where most tumors occur, including the horizontal duodenum.
  3. Horizontal (Third) Part: Runs horizontally across the abdomen.
  4. Ascending (Fourth) Part: Connects to the jejunum, another part of the small intestine.
• Function: It plays a crucial role in digestion by receiving chyme from the stomach and digestive enzymes from the pancreas and bile from the liver.

Types of Duodenal Tumors

Duodenal tumors can be classified based on their origin and nature:

1. Adenomas: Benign? glandular tumors.
2. Carcinomas: Malignant? tumors, such as:
   • Adenocarcinoma: Cancer originating from glandular cells.
   • Neuroendocrine Tumors: Affect hormone-producing cells.
3. Lymphomas: Cancer of the lymphatic system cells.
4. Gastrointestinal Stromal Tumors (GISTs): Originating from connective tissue.
5. Polypoid Tumors: Growths resembling polyps.
6. Sarcomas: Rare malignant? tumors from connective tissues.
