Classification

Choledocholithiasis can be classified as Primary or Secondary

  • Primary Choledocholithiasis is classified based on gallstones formed directly within the biliary and obstructing the common bile duct. Primary Choledocholithiasis is composed of brownstones and is less common compared to secondary choledocholithiasis. Primary choledocholithiasis often affect the biliary tree diffusely and have both intrahepatic and extrahepatic biliary stones. Intrahepatic stones may be complicated by recurrent pyogenic cholangitis.[1]
  • Secondary Choledocholithiasis is classified based on gallstones formed from the gall bladder and transported to block the common bile duct. This type of Choledocholithiasis is the most common type of Choledocholithiasis. The stone composition of secondary choledocholithiasis is similar to cholelithiasis with cholesterol stone as the most common type, and the cause is identical to the causes of gallstones. About 4.6% to 18.8% of patients undergoing cholecystectomy is found to have choledocholithiasis.[2]
