Most people have just one pancreatic duct
. However, some have an additional accessory pancreatic duct
, called the Duct of Santorini
, which connects straight to the duodenum
at the minor duodenal papilla
. Both these ducts connect to the second part (the vertical one) of the duodenum
However, the Duct of Santorini, which bypasses the Ampulla of Vater, is non-functional whereas the Duct of Wirsung is functional and carries the digestive enzymes released by the pancreas.
It is named for Giovanni Domenico Santorini.
