Annular Pancreas in Adult

ABSTRACT

An annular pancreas is a rare congenital variant of the pancreatic anatomy, which may cause symptoms of gastric outlet obstruction and recurrent pancreatitis, and is often hard to diagnose before operation. The case of an annular pancreas with intermittent abdominal pain in a 38-year-old alcoholic man is described. A duodenal obstruction with consecutive ulcers was the clinical manifestation in this patient. The annular pancreas was diagnosed by using hypertonic duodenography followed by pancreatic angiography. The duodenoscopy revealed stenosis of the pancreas. A duodeno-duodenostomy relieved the symptoms. The patient had an uneventful recovery following a operation.
