Duodenum Circular Folds Obstruction

The duodenum is the first part of the small intestine that comes right after the stomach. Its main job is to break down food coming from the stomach so the body can absorb nutrients. The circular folds (also called plicae circulares) are tiny, raised ridges inside the duodenum that increase surface area to help absorb nutrients. Duodenum circular folds obstruction refers to a blockage or narrowing of the duodenum that affects the normal flow of food and digestive juices.

Let’s explore this condition in detail, from anatomy to treatments, symptoms, causes, and more. This guide is designed to be easy to understand and helpful for both patients and those looking to learn more about this condition.

Anatomy of the Duodenum and Circular Folds

The duodenum is around 25-30 cm long and is divided into four parts:

1. Superior part: Connects to the stomach.
2. Descending part: Where bile and pancreatic juices enter to help break down food.
3. Horizontal part: Runs horizontally across the abdomen.
4. Ascending part: Leads into the next section of the small intestine (jejunum).

Circular folds, also called plicae circulares, are ridges or folds inside the wall of the small intestine. These folds are permanent, meaning they don’t flatten out, and they help slow down the movement of food, giving the intestine more time to absorb nutrients.

Types of Duodenal Obstructions

1. Complete Obstruction: The duodenum is fully blocked, preventing food and liquids from passing through.
2. Partial Obstruction: There’s a narrowing or partial blockage that still allows some food and liquid to pass.
3. Congenital Obstruction: This is a birth defect where part of the duodenum doesn’t form properly.
4. Acquired Obstruction: This type develops later in life, usually due to injury, inflammation, or disease.

Causes of Duodenum Circular Folds Obstruction

1. Congenital duodenal atresia (a birth defect)
2. Duodenal web (a thin layer of tissue blocking the duodenum)
3. Crohn’s disease (inflammatory bowel disease)
4. Duodenal ulcers (sores that cause swelling or scarring)
5. Intestinal adhesions (bands of tissue from previous surgery)
6. Tumors or cancers (can block the duodenum)
7. Gastrointestinal stromal tumors (GIST)
8. Pancreatitis (inflammation of the pancreas)
9. Gallstones (may block the duodenum)
10. Intestinal hernias
11. Intussusception (one part of the intestine slides into another)
12. Volvulus (twisting of the intestine)
13. Celiac disease (autoimmune reaction to gluten)
14. Peptic ulcers
15. Radiation therapy damage
16. Foreign bodies (objects accidentally swallowed)
17. Infections (e.g., tuberculosis)
18. Trauma or injury to the abdomen
19. Cystic fibrosis (thick mucus blocks the intestines)
20. Vascular problems (like a superior mesenteric artery syndrome)
