An unusual cause of gastric outlet obstruction-incomplete annular pancreas.

Annular pancreas (AP) is a developmental disorder uncommonly suspected in adults. We report a case presenting with signs and symptoms of progressive gastric outlet obstruction. The diagnosis was suggested on pre-operative imaging and confirmed at laparotomy where the patient was successfully treated with a bypass procedure.
