==Background==
<languages/>
The biliary system includes the hepatic bile canaliculi, intrahepatic ducts, extrahepatic ducts, the gall bladder, the cystic duct, and the common bile duct. The liver produces bile, which is not only a byproduct of red blood cell breakdown, but also aids in digestion. The gallbladder stores bile until stimulated, upon which bile flows out the gallbladder, down the cystic duct into the common bile duct, and ultimately into the 1st portion of the duodenum.

Gallstones are classified as cholesterol stones and pigmented stones (black and brown), and are present in approx 20% of females and 8% of males in the United States. It is these stones that cause the majority of all biliary tract problems, and depending on where the stone become impacted, specific problems occur.
Choledocholithiasis occurs when a stone is expelled out of the gallbladder and becomes impacted in the common bile duct.

Background

  • Occurs when stone expelled from gallbladder becomes impacted in the common bile duct
  • If infected, becomes Cholangitis

Anatomy & Pathophysiology

  • Gallstones are classified as cholesterol stones and pigmented stones (black and brown), and are present in approx 20% of females and 8% of males in the United States
  • These stones cause the majority of all biliary tract problems, and depending on where the stone become impacted, specific problems occur.
  • Bile flows out the gallbladder, down the cystic duct into the common bile duct, and ultimately into the 1st portion of the duodenum.

Gallbladder disease types

Gallbladder anatomy (overview).
Gallbladder anatomy
Bile duct and pancreas anatomy. 1. Bile ducts: 2. Intrahepatic bile ducts; 3. Left and right hepatic ducts; 4. Common hepatic duct; 5. Cystic duct; 6. Common bile duct; 7. Sphincter of Oddi; 8. Major duodenal papilla; 9. Gallbladder; 10-11. Right and left lobes of liver; 12. Spleen; 13. Esophagus; 14. Stomach; 15. Pancreas: 16. Accessory pancreatic duct; 17. Pancreatic duct; 18. Small intestine; 19. Duodenum; 20. Jejunum; 21-22: Right and left kidneys.


Clinical Features

  • RUQ pain
    • Radiation to the right shoulder (phrenic nerve irritation)
    • Early pain characterized as colicky, intermittent
    • Once impacted, is constant and severe
  • Nausea and Vomiting
  • Jaundice/scleral icterus
    • Caused by buildup of direct bilirubin in blood


Differential Diagnosis

RUQ Pain


Evaluation

RUQ ultrasound showing non-obstructing common bile duct stone.
  • LFTs, lipase, and basic chemistry
  • Imaging
    • RUQ Ultrasound
      • Noninvasive and quick
      • Common bile duct < 6 mm plus 1mm per decade after 60 yrs old
      • US is highly sensitive and specific for acute cholecystitis, much less sensitive/specific in identifying cholelithiasis due to exam limitations (i.e. difficulty identifying the CBD)
    • ERCP - highly sensitive and specific, also therapeutic
    • MRCP - comparable sensitivity/specificity to ERCP
    • HIDA Scan - not useful, as IDA (technetium 99m-labeled iminodiacetic acid) can still go into gallbladder


Management


Disposition

  • Admission to medical services
    • Consult to GI for spherincerotomy and stone removal vs General Surgery for operative management
    • Strong predictors for choledocholithiasis on ERCP[1]:
      • Clinical ascending cholangitis
      • CBD stones on US
      • Total bilirubin > 4 mg/dL
