Bile duct injury is mostly caused by cholecystectomy in cases of bile duct injury. In the process of cholecystectomy, the complications of bile duct injury are a very difficult problem in biliary surgery. If common bile duct injury occurs, it will cause bile outflow, acute, biliary and diffuse peritonitis, chills, high fever, jaundice and abdominal pain, which is life-threatening.
After cholecystectomy for choledocholithiasis, the bile salt pool was significantly reduced and the bile concentration was lost. The decrease of bile acid concentration in hepatobiliary duct leads to the decrease of cholesterol ablation ability, which is easy to lead to cholesterol accumulation and easy to form stones, that is, common bile duct stones.
The recurrence of polyps after gallbladder surgery will aggravate the imbalance between liver and gallbladder, which will further aggravate the causes of polyp formation and lead to the formation of new polyps in hepatic duct and common bile duct.
