Duodenum Circular Folds Disorders

The duodenum is the first part of the small intestine, playing a crucial role in digestion. It connects the stomach to the jejunum (the second part of the small intestine) and is essential for nutrient absorption. One of its distinctive features is the circular folds, also known as plicae circulares, which increase the surface area for absorption.

Anatomy of the Duodenum

• Location: The duodenum is about 10-12 inches long and is shaped like a “C.” It is located in the upper abdomen, just below the stomach.
• Structure: It has four sections:
  • Superior part: Begins at the pylorus of the stomach.
  • Descending part: Curves downwards, receives bile and pancreatic juices.
  • Horizontal part: Crosses horizontally.
  • Ascending part: Connects to the jejunum.

Circular Folds (Plicae Circulares)

• Description: These are deep folds in the intestinal lining that help increase the surface area for nutrient absorption.
• Function: They slow down the passage of food, allowing more time for absorption.

Types of Duodenal Disorders

1. Duodenitis: Inflammation of the duodenum.
2. Peptic Ulcer Disease: Sores in the lining of the duodenum.
3. Duodenal Obstruction: Blockage in the duodenum.
4. Celiac Disease: An autoimmune disorder where gluten damages the intestinal lining.
5. Crohn’s Disease: A type of inflammatory bowel disease that can affect the duodenum.
6. Intestinal Ischemia: Reduced blood flow to the intestine.
7. Diverticulitis: Inflammation of diverticula in the intestine.
8. Lactose Intolerance: Inability to digest lactose, leading to gastrointestinal symptoms.
9. Bacterial Overgrowth: Excess bacteria in the small intestine.
10. Tumors: Benign or malignant growths in the duodenum.
