Using a probe and forceps, remove the stroma from the posterior surface of the pancreas to expose the pancreatic ducts. The large main pancreatic duct begins in the tail of the pancreas and ends at the hepatopancreatic ampulla on the greater duodenal papilla in the second part of the duodenum. Along its course, it receives numerous smaller pancreatic ducts.
The accessory pancreatic duct begins within the head of the pancreas, superior to the main pancreatic duct. It ends at the lesser duodenal papilla, which is also located in the second part of the duodenum.
