Abstract

Annular pancreas is a rare congenital abnormality characterized by a ring of pancreatic tissue encircling the descending part of the duodenum. It is considered to originate from incomplete ventral pancreatic bud rotation. A 39-year-old male with refractory nausea and vomiting despite receiving appropriate medical treatment underwent contrast-enhanced computed tomography; it revealed an annular pancreas encircling the descending part of the duodenum. We found that surgical resection of the annular pancreas relieved nausea and vomiting due to duodenal obstruction.
