Common bile duct with orifice of cystic duct
and evident pits corresponding to
underlying sacculi of Beale. |
Fig 13 - COMMON BILE DUCT(CHOLEDOCUS)
Can be divided in sopraduodenal,retroduodenal,pancreatic and
intraduodenal segments.It is 1.5 -5.0 cm long, 1 mm thick and
measures from 0.4 to 1.2 cm in diameter.The mucosa shows
fine pits (sacculi of Beale).It enetrs the duodenal lumen with the
pancreatic duct,jointly in 2/3 of the cases and separately in 1/3 of
the cases.At the duodenal lumen these tow ducts form a nipple
like protuberance called "papilla of Vater".The common bile duct
inits intrapancreatic and intraduodenal segments contains a layer
of circular and longitudinal smooth musculature which forms a
bile flow regulating sphincter,the "sphincter of Oddi".The
secondary pancreatic duct of Santorini may enter the duodenum
2 cm above the papilla of vater and there it forms the minor
papila.The sacculi of Beale are again mucinous glands in the
wall of the choledocus not to be iterpreted s adenacarcinoma.
