A periampullary diverticulum is a location-specific type of duodenal diverticulum.
The incidence is reported to increase with age with reported rates as high as 27%.
It is located close to the region of the ampulla of Vater often involving the D2 segment.
Associations
- can be associated with increased risk of failure in cannulation of the papilla.
- associated with an incompetent sphincter of Oddi and colonization of the bile ducts with beta-glucuronidase-producing organisms.
- implicated in the pathogenesis of pigment common bile duct stones, but there is no conclusive evidence that they are associated with cholecystolithiasis or pancreatitis.
