What kind of doctor treats Pancreas Divisum?
A gastroenterologist, a doctor who treats diseases of the digestive system, usually cares for people with pancreas divisum. If other treatments do not work, a surgeon may be needed. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is pancreas divisum?
Pancreas divisum is a birth defect in which parts of the pancreas do not join together. The pancreas is a long, flat organ between the stomach and the spine. It helps with food digestion.
Pancreas divisum is the most common birth defect of the pancreas. In many cases, it goes undetected and causes no problems. Another name for it is pancreatic divisum.
Before birth, two separate pieces of tissue join to form the pancreas. Each part has a tube, called a duct. When the parts join, a final duct forms, called the pancreatic duct. Digestive juices called enzymes normally flow through this duct. In pancreas divisum, the ducts do not join. Fluid from the two parts drains into separate areas of the upper small intestine, called the duodenum.
Symptoms
Many people with pancreas divisum do not have any symptoms. Trouble can start if a pancreatic duct becomes blocked. Swelling and tissue damage, called pancreatitis, may then develop. Pancreatitis is the main complication of pancreas divisum. Symptoms of pancreatitis include:
- Belly (abdominal) pain, most often in the upper belly, that may be felt in the back.
- Belly swelling.
- Nausea or vomiting.
Pain from sudden (acute) pancreatitis can begin slowly or suddenly in the upper belly. It can be mild or severe and may last for several days. A swollen or tender belly can also be a sign. In long-lasting (chronic) pancreatitis, the pain may become worse after eating.
Causes and who gets it
The cause of the defect is unknown. The defect occurs in 5% to 15% of people. It is present at birth.
Pancreatitis is the main problem pancreas divisum can cause. The most common cause of sudden pancreatitis is gallstones.
How doctors diagnose it
Doctors may use these tests.
- Abdominal ultrasound, a scan that uses sound waves.
- Abdominal CT scan, a scan that takes detailed x-ray pictures.
- Amylase and lipase blood tests, which check two digestive enzymes in the blood.
- ERCP, a test that looks at the ducts with an endoscope, a thin tool with a camera.
- MRCP, an MRI scan that shows the ducts.
- Endoscopic ultrasound, an ultrasound done with an endoscope.
Treatment
Treatment may be needed if you have symptoms, or if pancreatitis keeps coming back.
- ERCP with a cut to enlarge the opening where the pancreatic duct drains.
- Placing a stent, which is a small tube, to keep the duct from getting blocked.
You may need surgery if these treatments do not work. Most of the time, the outcome is good.
When to see a doctor
Contact your health care provider if you develop symptoms of this disorder. Seek care right away if you have fever or chills, or yellow skin or yellow whites of the eyes, called jaundice. These signs can point to a serious infection or a blockage. Left untreated, these problems can be fatal.
Call 911 or go to the emergency room if you have severe belly pain or pressure, trouble breathing, fainting, chest pain or discomfort lasting two minutes or more, or you vomit blood.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. This kind of doctor can review your symptoms and order first tests or imaging. They can also refer you to a gastroenterologist and help coordinate your care over time.

No, many people do not have any symptoms. Symptoms can start if a duct becomes blocked and pancreatitis develops.
Can pancreas divisum be prevented?
No, there is no known way to prevent it. This is because the condition is present at birth.
What is the outlook for pancreas divisum?
The outlook is good most of the time. The main complication is pancreatitis, which is swelling and tissue damage in the pancreas.
