Q

Journey of bile duct?

A
  • Descends posteriorly to 1st (superior part of duodenum)
  • Travels into groove on posterior aspect of pancreas
  • Joins main pancreatic duct to form ampulla of vater
  • Both then drain into 2nd part of duodenum through major duodenal papilla

Q

What happens in ERCP?

A
  • Endoscope is inserted through the oral cavity, oesphagus, stomach and duodenum
  • Cannula is then placed in the major duodenal papilla and radio-opaque dye is injected back into biliary tree, radiographic images are taken of dye filled tree

Q

What happens when there is an obstruction of the biliary tree?

A

Flow of bile can’t go down into duodenum as it should so it is pushed back to liver

=overspill into blood (including bilirubin)
