The pancreatic duct or duct of Wirsung (also, the major pancreatic duct due to the existence of an accessory pancreatic duct) is a duct joining the pancreas to the common bile duct. This supplies it with pancreatic juice from the exocrine pancreas , which aids in digestion .
When present, the sphincter is known as the sphincter of Helly, and the duct as the accessory pancreatic duct of Santorini. In 10% of people, the minor duodenal papilla is the prime duct for drainage of the pancreas, [1] although in others it may not be present at all. [2]

Two ducts, the main pancreatic duct and a smaller accessory pancreatic duct run through the body of the pancreas. The main pancreatic duct joins with the common bile duct forming a small ballooning called the ampulla of Vater (hepatopancreatic ampulla). This ampulla is surrounded by a muscle, the sphincter of Oddi.
The embryology also explains the strange zig-zag course of the main pancreatic duct and the occasional appearance of an accessory pancreatic duct. The uncinate process, unlike the remainder of the organ, passes posteriorly to the superior mesenteric vein (it can pass posteriorly to the superior mesenteric artery , but this is less common).

The ventral and dorsal pancreatic buds (or pancreatic diverticula) are outgrowths of the duodenum during human embryogenesis.They join to form the adult pancreas.. The proximal portion of the dorsal pancreatic bud gives rise to the accessory pancreatic duct, while the distal portion of the dorsal pancreatic bud and ventral pancreatic bud give rise to the major pancreatic duct.
Hemosuccus pancreaticus is a rare cause of hemorrhage in the gastrointestinal tract.It is caused by a bleeding source in the pancreas, pancreatic duct, or structures adjacent to the pancreas, such as the splenic artery, that bleed into the pancreatic duct, which is connected with the bowel at the duodenum, the first part of the small intestine.
