Pancreas divisum is a birth defect in which parts of the pancreas do not join together. The pancreas is a long, flat organ located between the stomach and spine. It helps in food digestion.
Pancreas divisum is the most common birth defect of the pancreas. In many cases, this defect goes undetected and causes no problems. The cause of the defect is unknown.
As a baby develops in the womb, 2 separate pieces of tissue join together to form the pancreas. Each part has a tube, called a duct. When the parts join together, a final duct, called the pancreatic duct, is formed. Fluid and digestive juices (enzymes) produced by the pancreas normally flow through this duct.
If the ducts do not join while the baby is developing in the womb, pancreas divisum results. Fluid from the 2 parts of the pancreas drains into separate areas of the upper portion of the small intestine (duodenum). This occurs in 5% to 15% of people.
If a pancreatic duct becomes blocked, swelling and tissue damage (pancreatitis) may develop.
Note: Unless you have pancreatitis, you will not have symptoms.
Exams and Tests
You may have the following tests:
The following treatments may be needed if you have symptoms of the condition, or if pancreatitis keeps returning:
You may need surgery if these treatments do not work.
Most of the time, the outcome is good.
The main complication of pancreas divisum is pancreatitis.
When to Contact a Medical Professional

Because this condition is present at birth, there is no known way to prevent it.
