Common bile duct stones

Common bile duct stones are mostly located in the middle and lower sections of the common bile duct. However, as the stones increase, increase and the common bile duct expands, the stones accumulate or move up and down, the common hepatic duct is often involved. The meaning of common bile duct stones should actually include the entire extrahepatic bile duct stones including the common hepatic duct. The source of common bile duct stones is divided into primary and secondary. Primary common bile duct stones are a component of primary bile duct stones, which can form in the common bile duct, or the stones that originally originated in the intrahepatic bile duct fall into the common bile duct. Secondary choledocholithiasis means that the stones originally in the gallbladder descend through the gallbladder duct to the common bile duct.
