duodenal papilla

The ampulla is specifically located at the major duodenal papilla.

The other names of minor duodenal papilla is Santorini's minor caruncle.

The junction between the embryological foregut and midgut lies just below the major duodenal papilla.

The minor duodenal papilla is the opening of the accessory pancreatic duct into the descending second section of the duodenum.

This part of the duodenum also contains the minor duodenal papilla, the entrance for the accessory pancreatic duct (of Santorini).

However, some have an additional accessory pancreatic duct also called the Duct of Santorini, which connects straight to the duodenum at the minor duodenal papilla.

These bile acids travel to the gall bladder during the interdigestive phase for storage and to the descending part of the duodenum via the common bile duct through the major duodenal papilla during digestion.

This operation is performed to treat cancerous tumours on the head of the pancreas, malignant tumors involving common bile duct, duodenal papilla, duodenum near the pancreas, and/or pancreatitis with or without definitive cause.

Proximal to the 2nd part of the duodenum (approximately at the major duodenal papilla - where the bile duct enters) the arterial supply is from the gastroduodenal artery and its branch the superior pancreaticoduodenal artery.

The common bile duct and the pancreatic duct together perforate the medial side of the second portion of the duodenum obliquely, some 7 to 10 cm below the pylorus, forming a structure called the major duodenal papilla.

The pancreatic duct joins the common bile duct just prior to the ampulla of Vater, after which both ducts perforate the medial side of the second portion of the duodenum at the major duodenal papilla.

The pancreatic duct and common bile duct enter the descending duodenum, commonly known together as the hepatopancreatic duct (or pancreatic duct in the United States), through the major duodenal papilla (known as Ampulla of Vater).
