What is annular pancreas?
Annular pancreas is the most common birth defect seen in the pancreas. The pancreas is an organ that plays an important part in your digestive process. The term annular pancreas means that a ring of extra pancreatic tissue covers the first part of your small intestine (duodenum). It goes all the way up to your pancreas. Your pancreas can still function, but the extra tissue can cause a number of symptoms. It can also disrupt your digestive process and other bodily functions.
What causes annular pancreas?
Annular pancreas is a birth defect. The cause is not known.
What are the symptoms of annular pancreas?
Annular pancreas is a rare condition. The exact number of people born with it is unknown. Healthcare providers may diagnose the defect in babies, even before birth. Sometimes, however, it’s not recognized and diagnosed until after symptoms start. This could be in childhood or even adulthood. In infants and young children, it can cause intolerance to food, vomiting, and swollen belly. In older children and adults, it can cause similar symptoms and chronic belly pain. Most people with annular pancreas don’t have any symptoms.
Annular pancreas is linked with Down syndrome. About one-fourth of people with this condition also have Down syndrome.
Annular pancreas can lead to other problems such as peptic ulcer disease, acute or chronic pancreatitis, and jaundice
How is annular pancreas diagnosed?
Your healthcare provider will do an exam and ask about your health history. Other tests may be done to evaluate whether you have annular pancreas.
An ultrasound may identify the presence of annular pancreas even before a baby is born. If the diagnosis is made later in life, it’s often found through an upper GI series X-ray, CT scan, or MRI. These diagnostic scans often identify the tissue that causes a narrowing of the duodenum and air pockets typical of a blockage.
How is annular pancreas treated?
If the condition causes problems, surgery is the typical treatment. The surgery involves bypassing the blockage that the annular pancreas causes. The annular pancreas itself is rarely removed. This would risk injuring the pancreatic tube and causing a leak of fluids within it. A surgeon does the surgery through an incision in the upper part of the belly.
What are possible complications of annular pancreas?
Complications related to annular pancreas include blockage of the duodenum and poor liver function. It can result in pancreatitis, small intestine ulcers, intestinal blockage, and jaundice. In some cases, an abnormal connection between the windpipe and the esophagus can also be associated with an annular pancreas. In rare cases, pancreatic cancer is a complication related to annular pancreas.
When should I call my healthcare provider?
