  1. 1The biliary tree descends from the [blank_start]hepatocytes[blank_end], gradually enlarging and merging to the right and left hepatic ducts . These 2 merge at porta hepatis to form the [blank_start]Common Hepatic Duct[blank_end] .The Common Bile Duct (CBD) is formed by the junction of the [blank_start]cystic duct[blank_end] from the gallbladder with the CHD. The CBD traverses through the head of the pancreas entering the duodenum at the [blank_start]Ampulla of Vater[blank_end] through the Sphincter of Oddi. Prior to draining into the duodenum the CBD is joined by the pancreatic duct, or [blank_start]duct of Wirsung[blank_end] and the accessory pancreatic duct ([blank_start]duct of Santorini[blank_end])
    1. Ahepatocytes
    2. BCommon Hepatic Duct
    3. Ccystic duct
    4. DAmpulla of Vater
    5. Educt of Wirsung
    6. Fduct of Santorini
  2. 2normal CBD Measurements
    1. A<6mm (+1mm per decade over 60yrs)
    2. B<7mm (+1mm per decade over 60yrs)
    3. C<9mm (+1mm per decade over 60yrs)
    4. D<10mm (+1mm per decade over 60yrs)
  3. 3CBD Measurements Post Cholecystectomy
    1. Aup to 10mm (but should gradually taper into the head of pancreas). The common bile duct should never exceed 10mm in diameter.
    2. Bup to 11mm (but should gradually taper into the head of pancreas)
    3. Cup to 12mm (but should gradually taper into the head of pancreas)
    4. Dup to 13mm (but should gradually taper into the head of pancreas)
  4. 4What is CHOLEDOCHOLITHIASIS
    1. AAt least one gallstone in the common bile duct
    2. BBacterial infection due to Billary obstruction
    3. Cnon-obstrucive, saccular bile duct dilations.
  5. 5Choledocholithiasis is when there is at least one [blank_start]gallstone[blank_end] in the common bile duct.

    About [blank_start]15[blank_end]% of people with gallstones will develop stones in the common bile duct. Risk factors include a [blank_start]history[blank_end] of gallstones. However, choledocholithiasis can occur in people who have had their [blank_start]gallbladder[blank_end] removed. Blockage and infection caused by stones in the [blank_start]biliary[blank_end] tract can be life threatening.
    1. Agallstone
    2. Bhistory
    3. Cgallbladder
    4. D15
    5. Ebiliary
  6. 6sonographic findings of Choledocholithiasis include stones appear as [blank_start]echogenic[blank_end] rounded foci. There may not be any [blank_start]shadowing[blank_end]. Sometimes the initial sign is that the bile duct is [blank_start]dilated[blank_end]. There may also be [blank_start]intrahepatic[blank_end] duct dilatation. [blank_start]Mobile[blank_end] Calculus: By rolling the patient onto their side, you may be able to visualise the calculus rolling within the CBD, excluding impaction.
    1. AMobile
    2. Bechogenic
    3. Cshadowing
    4. Ddilated
    5. Eintrahepatic
