An annular pancreas is a rare congenital condition in which a ring of pancreatic tissue surrounds the duodenum (the first part of the small intestine). This ring may be complete or incomplete. When it constricts the duodenum, it can narrow or block the passage of food, leading to digestive discomfort. Diagnosis is typically made with imaging studies such as CT, MRI or contrast X-rays that may show a "double-bubble" sign.
Many adults with annular pancreas remain symptom-free, especially if the ring is loose. When symptoms do occur, they often stem from partial obstruction or irritation of the duodenum:

Annular pancreas occurs in about 1 in 12,000 people. Many individuals remain undiagnosed until adulthood when symptoms prompt imaging studies.
Yes. If symptoms are mild, you can manage with dietary changes, medications, and regular checkups. Surgery is reserved for cases with persistent or severe blockage.
Diagnosis typically involves CT or MRI scans. An abdominal X-ray may show the classic "double bubble" sign, and endoscopic ultrasound can provide detailed images of the pancreatic tissue.
Incomplete annular pancreas refers to a partial ring of pancreatic tissue around the duodenum. These cases often cause fewer or milder symptoms than a complete ring.
No. Surgery is only needed if dietary modifications and medications fail to relieve symptoms or if there is significant intestinal blockage.
Most patients stay in the hospital for 3-5 days after procedures like duodenojejunostomy. Full recovery typically takes 4-6 weeks, depending on individual health and procedure type.
Yes. A constricted pancreatic duct can cause inflammation, leading to bouts of pancreatitis if not properly managed.
In infants, annular pancreas usually presents with early vomiting and feeding difficulties. Adults more commonly experience chronic abdominal pain, bloating, reflux, and malabsorption symptoms.
