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])

2normal CBD Measurements
- A<6mm (+1mm per decade over 60yrs)
- B<7mm (+1mm per decade over 60yrs)
- C<9mm (+1mm per decade over 60yrs)
- D<10mm (+1mm per decade over 60yrs)
3CBD Measurements Post Cholecystectomy
- Aup to 10mm (but should gradually taper into the head of pancreas). The common bile duct should never exceed 10mm in diameter.
- Bup to 11mm (but should gradually taper into the head of pancreas)
- Cup to 12mm (but should gradually taper into the head of pancreas)
- Dup to 13mm (but should gradually taper into the head of pancreas)
4What is CHOLEDOCHOLITHIASIS
- AAt least one gallstone in the common bile duct
- BBacterial infection due to Billary obstruction
- Cnon-obstrucive, saccular bile duct dilations.
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.- Agallstone

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.
