Annular pancreas in adults: imaging features in seven patients.

摘要: Background: Annular pancreas is a rare congenital abnormality that may be associated with variable degrees of duodenal obstruction. This diagnosis often overlooked in adult patients who present symptoms suggestive Imaging evaluation aids establishing the diagnosis. We evaluated imaging findings seven known annular pancreas. Methods: Seven abdominal had one or more following studies: upper gastrointestinal (UGI) series, computed tomography (CT), and endoscopic retrograde cholangiopancreatography (ERCP). All underwent subsequent laparotomy as part routine care. Surgical were correlated each patient. Results: UGI series suitable for demonstrating different narrowing at level pancreatic annulus. Contrast-enhanced CT useful visualizing directly complete partial tissue. ERCP particularly annulus duct coursing around duodenum. Conclusions: plays pivotal role avoiding surgery confirmation its cost risks.
