Overview

Choledocholithiasis causes include primary and secondary causes.

Causes

While stones can frequently pass through the common bile duct into the duodenum, some stones may be too large to passthrough the CBD and will cause an obstruction. Choledocholithiasis causes include primary and secondary causes.

• Primary causes are rare, and they are usually brown pigment stones formed in the bile duct. Recurrent pyogenic cholangitis (RCC), also known as Oriental Cholangiohepatitis hepatolithiasis, is an intrahepatic brown pigment stone exclusive to individuals who live or lived in southeast Asia. It is caused by a bacterial in the bile duct, undernutrition, and parasitic infection (e.g., Clonorchis Sinensis, Opisthorchis viverrini) leading to chronic bacterial cholangitis with hepatolithiasis|primary hepatolithiasis.
• Secondary causes occur in greater than 85% of people in a developed country, and about 10% presents symptomatically after Cholecystectomy. Secondary causes are caused by stones from the gallbladder, with cholesterol stones being the most common.

Other causes include residual stones that develop in the ducts greater than three years after surgery.
