Pancreas Divisum

It happens because of how the pancreas formed before birth; nothing in a person's lifestyle causes it. If pancreatitis does occur, doctors first look for the common causes such as gallstones, alcohol, high triglycerides (a type of blood fat), medicines and genetic factors, before blaming the divisum. Pancreas divisum alone is not enough to explain pancreatitis in most people.

It is one of the most common inborn variations of the pancreas, and the great majority of people who have it never develop symptoms and never know. It is often found by chance during scans done for another reason.

The usual test is an MRI of the bile ducts and pancreas (MRCP), sometimes with secretin to stimulate the pancreas, which shows the duct pattern without any instrument entering the body. Endoscopic ultrasound can give extra detail and look for other causes of pancreatitis. ERCP, an endoscopic X-ray test of the ducts, is no longer used just to diagnose, because it carries a risk of pancreatitis, and is kept for treatment. Blood tests look for other causes such as gallstones, alcohol effects and high blood fats.

If you have divisum without symptoms, no changes are needed. If you have had pancreatitis, these steps lower the risk of further attacks.

• Avoid alcohol completely if you have had pancreatitis.

• Do not smoke; smoking increases the risk of pancreatitis.

• Keep a healthy weight and exercise regularly.

• Do not take supplements or medicines that may inflame the pancreas without asking your doctor.

• Know the warning signs of an attack so you can get help early.

There is no specific diet for pancreas divisum. If you have had pancreatitis, a healthy diet lowers the chance of recurrence.

• Choose a balanced diet with plenty of vegetables, fruit and whole grains.

• Limit very fatty and fried meals, which may trigger pain in some people.

• Eat smaller, more frequent meals if large meals bring on pain.

• If your blood triglycerides are high, follow the diet advice to bring them down.

There is no medicine that corrects pancreas divisum. Medicines are used for pain or to treat other causes of pancreatitis, as decided by your doctor.

• Simple pain relief is chosen by your doctor, who will avoid medicines that could harm you.

• Pancreatic enzyme capsules may be used if there is pancreatic damage with poor digestion.

• Medicines for high blood fats or other conditions help to reduce attacks.

• Never start herbal products or supplements without checking first.

Procedures are only considered in a small group with repeated attacks of pancreatitis where no other cause is found. This should be discussed in a specialist centre.

• Endoscopic treatment (ERCP) can widen the minor opening, sometimes with a temporary stent, to improve drainage.

• ERCP has its own risks, including pancreatitis, bleeding and infection; the benefits and risks should be discussed in detail.

• Surgery on the minor opening is rarely used when endoscopic treatment is not possible or fails.

Experts now agree that pancreas divisum is mostly a harmless variant and that the diagnosis alone should not lead to treatment. Endoscopic therapy may help a selected group of people who have repeated unexplained attacks of pancreatitis, while its value for pain without pancreatitis is less clear. Genetic factors seem to play a role in those who do get pancreatitis.

For most people the outlook is excellent and no treatment is needed. For those with repeated pancreatitis, endoscopic treatment can reduce attacks in some, but not all. Avoiding alcohol and smoking and treating other causes lowers the risk of further attacks.

• Is my pancreas divisum likely to be the cause of my symptoms?

• Have other causes of pancreatitis been checked?

• Would an endoscopic procedure help me, and what are the risks?

• Do I need genetic testing or follow-up?

• What should I do if I get an attack of pain?
