Dorsal pancreatic duct pancreatic ducts. Medical search. Frequent questions

Rarely the bleeding is not channeled into the bowel from the main pancreatic duct (or duct of Wirsung), but rather comes from the accessory pancreatic duct (or duct of Santorini). (wikipedia.org)
In patients with pancreas divisum, a congenital anomaly in which the dorsal and ventral pancreatic ducts fail to fuse, acute pancreatitis may result from stenosis of the minor papilla with obstruction to flow from the accessory pancreatic duct, although concomitant gene variants, particularly in the cystic fibrosis transmembrane conductance regulator ( CFTR ) gene, may account for acute pancreatitis in these patients. (mhmedical.com)
The remaining proximal part (head) of the duct of the dorsal bud remains as the accessory pancreatic duct (of Santorini). (medscape.com)
The connecting stalk between the ventral rudiment and the hepatic bud becomes the main duct of the pancreas, while the connexion of the dorsal outgrowth with the duodenum remains as the accessory pancreatic duct. (co.ma)
ventral and dorsal pancreas along with their ducts fuse so duct of Wirsung (W) becomes major pancreatic duct and distal part of duct of Santorini (S) becomes accessory pancreatic duct. (comprehensivephysiology.com)
Though Wirsüng himself and others did make the observation of occasionally seeing the duct to be double, the discovery of the accessory pancreatic duct as a normal variant is credited to Giovanni Domenico Santorini (1681-1737) (17). (pancreapedia.org)

The ventral bud rotates dorsally and fuses with the dorsal bud, and the duct of the distal part (body and tail) of the dorsal bud unites with the duct of the ventral bud to form the main pancreatic duct (of Wirsung). (medscape.com)
Because the common bile duct (CBD) also arises from the ventral bud, it forms a common channel with the main pancreatic duct. (medscape.com)
The lower (terminal) part of the CBD runs behind (or sometimes through) the upper half of the head of pancreas before it joins the main pancreatic duct (MPD) to form a common channel (ampulla). (medscape.com)
In 80% to 90% of individuals, the common bile duct and main pancreatic duct unite and emerge as a common channel through the ampulla of Vater. (clinicalgate.com)
In 1642, the main pancreatic duct was discovered by the German anatomist Johann Georg Wirsüng (1589-1643) during an autopsy of a human subject, engraving his finding on a copper plate as a method of reproducing the anatomical illustration (17). (pancreapedia.org)
The pancreatogram has blunting of the lateral branches, dilation of the main pancreatic duct, and filling defects consistent with pancreatolithiasis. (medscape.com)

Discussion: In the male patient inspection of the gall bladder revealed a diverticulum at the region of the Hartman, the specimen had a single artery and a single cystic duct, the wall of the specimen was thick containing a large stone whilst the diverticulum was thin-walled and had no stones. (fortuneonline.org)
The female patient inspection revealed duplicated gall bladder with two fundi, each containing stones, a common Hartman's pouch, and a single cystic duct and single artery. (fortuneonline.org)
At the most proximal end of the cystic duct, there is a discrete area of narrowing that helps to regulate the flow of bile into and out of the gallbladder. (clinicalgate.com)
The cystic duct is approximately 3 to 4 cm long and joins the common hepatic duct to form the common bile duct. (clinicalgate.com)

It occurs in the seventh week of intrauterine life and is due to a lack of fusion of the ductal systems of the dorsal and ventral pancreatic buds, an event that leads to the formation of a dominant dorsal pancreatic duct which drains through the minor papilla and a small ventral pancreatic duct which drains through the major papilla. (minervamedica.it)
Evidence of dorsal duct dilation on pancreatic imaging may suggest a stenotic minor papilla orifice, but is not a requirement for proceeding with minor papilla therapy [ 3 ]. (medilib.ir)
