Duodenal Ampulla Dysfunction

The duodenal ampulla, also known as the Ampulla of Vater, is a small opening located in the first part of the small intestine called the duodenum. This tiny structure is where two important ducts meet:

1. Common bile duct: Carries bile from the liver and gallbladder.
2. Pancreatic duct: Brings digestive enzymes from the pancreas.

These substances help digest fats and proteins. The flow through the ampulla is controlled by a muscle called the sphincter of Oddi.

Types of Duodenal Ampulla Dysfunction

Duodenal ampulla dysfunction, often referred to as Sphincter of Oddi Dysfunction (SOD), happens when the sphincter muscle doesn’t work properly. There are three main types:

1. Type I (Biliary Type):
   • Severe, recurrent pain.
   • Abnormal liver function tests.
   • Dilated bile duct.
2. Type II (Biliary Type):
   • Pain with one or two of the above features.
3. Type III (Pancreatic Type):
   • Pain without other abnormalities.

 Causes of Duodenal Ampulla Dysfunction

1. Gallbladder Removal (Cholecystectomy): Surgery can alter bile flow.
2. Gallstones: Stones can block the ducts.
3. Pancreatitis: Inflammation affects nearby structures.
4. Scarring: Injury or surgery can cause scar tissue.
5. Inflammation: Due to infections or autoimmune diseases.
