Presentation and treatment of annular pancreas in an adult population.

Abstract

1) Annular pancreas occasionally presents in the adult population. 2) Although gastric outlet obstruction was seen in two of seven patients, a plethora of additional presentations included pancreatic mass, pancreatitis, peptic ulcer disease, and post-operative obstructive jaundice. 3) Diagnosis of annular pancreas was most commonly suggested by upper GI series or endoscopic retrograde cholangiopancreatography. However, fully 40% of diagnoses required surgery for confirmation. 4) In contrast to the pediatric population in whom gastrojejunostomy or duodenojejunostomy is the treatment of choice, a variety of surgical as well as interventional endoscopic procedures were utilized for effective treatment in adults with annular pancreas.
