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.[1][2]
