Periampullary duodenal diverticulum

Epidemiology

Pathology

It is located close to the region of the duodenum often involving the D2 segment.

Associations
  • can be associated with increased risk of failure for cannulation of the papilla.
  • associated with an incompetent sphincter of Oddi and colonization of bile duct with beta-glucuronidase-producing organisms.
  • they are implicated in the pathogenesis of pigment common bile duct stones, but there is no conclusive evidence that they are associated with cholecystolithiasis or pancreatitis.
