The main complications of choledochoscopy include biliary tract infection, biliary tract hemorrhage and sinus injury. Among them, infection was associated with complicated intrahepatic bile duct stones, long operation time, high biliary pressure during operation, and poor postoperative T-tube drainage. Bleeding is related to coagulation dysfunction, improper lithotripsy, dilatation and tearing, violent lithotripsy, etc. Sinus injury is associated with poor healing of sinus, blind access, violent lithotomy, blind catheterization and other factors.
It is recommended to choose the appropriate time of diagnosis and treatment, prophylactic application of drugs, control operation time, maintain clear vision, pay attention to biliary pressure, avoid violence or blind operation, and close observation after surgery can reduce the occurrence or severity of complications.
