[Annular pancreas--a congenital abnormality of the pancreas]

Our case report on a 26-year-old male suffering from epigastric pain for several years should emphasize the fact, that even a rare congenital malformation like the annular pancreas must seriously discussed as a reason for the so called unspecific abdominal pain. Embryological development, age of manifestation, symptoms and therapeutic concepts are described. The importance of endoscopic methods such as gastroduodenal endoscopy and endoscopic retrograde cholangiopancreatography (ERCP) for a more precise and frequent diagnosis will be strengthened and the influence on the prevalence will be discussed.
