How is bile duct stone to return a responsibility?

First, when the biliary tract is infected, Escherichia coli is produced β- The activity of glucuronidase is very high. It can hydrolyze the conjugated bilirubin in bile to free bilirubin, which will combine with calcium ion in bile to form calcium bilirubin insoluble in water

Second, secondary biliary tract infection caused by biliary ascariasis is more likely to cause this kind of stone, because Ascaris lumbricoides residues, keratoderma eggs and the accompanying bacteria and inflammatory products can become the core of the stone.

Third: bile duct stenosis is bound to affect the smooth flow of bile, resulting in bile retention, bile pigment and cholesterol more easily precipitate to form stones. When combined with chronic inflammation, the process of stone formation is more rapid.
