Definitions

Choledocholithiasis are bile duct stones that can be either asymptomatic, symptomatic or symptomatic with complications of cholangitis or pancreatitis.

Terms Definitions
Choledocholithiasis (bile duct stones) Choledocholithiasis are crystallized pieces of bile containing cholesterol and bilirubin in the bile duct. It usually results from the migration of gallstones from the gallbladder into the biliary tract.
Primary choledocholithiasis Primary choledocholithiasis are biliary tract stones resulting from biliary stasis and not from the migration of gallstones from the gallbladder into the biliary tract.
Asymptomatic choledocholithiasis Asymptomatic choledocholithiasis refers to the presence of stones in the bile duct, that might be detected during imaging studies of the abdomen, in the absence of any symptoms.
Symptomatic and uncomplicated choledocholithiasis Symptomatic and uncomplicated choledocholithiasis refers to the presence of stones in the bile duct that are associated with symptoms in the absence of complications such as acute cholangitis or pancreatitis.
Symptomatic and complicated choledocholithiasis Symptomatic and complicated choledocholithiasis refers to the presence of stones in the bile duct with symptoms and complications such as acute cholangitis or pancreatitis.

Management of Symptomatic and Complicated Choledocholithiasis

Symptomatic and complicated choledocholithiasis refers to the presence of stones in the bile duct with symptoms and complications such as acute cholangitis or pancreatitis.

  • For the management of cholangitis, please click here.
  • For the management of pancreatitis, please click here.

Do's

  • Order serum liver biochemical tests and a transabdominal ultrasound of the right upper quadrant during the initial evaluation of suspected choledocholithiasis. These tests should be used to risk-stratify patients to guide further evaluation and management (Grade B).[3]
  • Consider EUS or MRCP in the diagnostic evaluation of postcholecystectomy patients suspected of having choledocholithiasis when initial laboratory and ultrasonography data are abnormal yet non diagnostic (Grade C).[3]
  • Consider sphincter of Oddi dysfunction as a differential diagnosis if EUS or MRCP did not detect any stones in the bile duct of postcholecystectomy patients suspected of having choledocholithiasis.
  • Laparoscopic cholecystectomy is preferred over open laparoscopy but conversion to open may be necessary and should not be considered a failure in the management.[4]

Dont's

  • Laparoscopic cholecystectomy is contraindicated in untreated coagulopathy, lack of equipment, lack of surgeon expertise, hostile abdomen, advanced cirrhosis/liver failure, and suspected gallbladder cancer.
