main pancreatic ducts การใช้

• The duct of the dorsal bud regresses, leaving the main pancreatic duct.
• The main pancreatic duct is formed by the fusion of the dorsal and ventral pancreas.
• It has two main ducts, the main pancreatic duct, and the accessory pancreatic duct.
• The main pancreatic duct needs to be 6mm in diameter in the body of the pancreas for this procedure to be possible.
• At this point of fusion, the main ducts of the ventral and dorsal pancreatic buds fuse, forming the main pancreatic duct.
• A Puestow procedure is indicated for the treatment of symptomatic chronic pancreatitis patients with pancreatic ductal obstruction and a dilated main pancreatic duct.
• Normally, the two ducts will fuse together to form one main pancreatic duct; this occurs in more than 90 % of embryos.
• The success rate is around 50 %, and the unsuccessful drainages are mostly caused by large ductal leaks or blockage of the main pancreatic duct.
• The transpapillary approach is used when the pseudocyst is in communication with the main pancreatic duct, and is also successful in patients with pancreatic duct disruption.
• The characteristic ERCP finding is segmental or diffuse irregular narrowing of the main pancreatic duct, usually accompanied by an extrinsic-appearing stricture of the distal bile duct.
• Main branch intraductal papillary mucinous neoplasms ( IPMNs ) are associated with dilatation of the main pancreatic duct, while side branch IPMNs are typically benign, and not associated with dilatation.
• 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 " ).
