γγA patient with bile duct cancer with portal vein and hepatic artery infiltration was successfully treated by ERCP, followed by enlarged pancreatic head decubitus resection and combined with portal vein and hepatic artery resection and reconstruction, and was discharged from the hospital.γγAt the time of consultation, the patient had severe jaundice, liver disease face, and elevated bilirubin of 420ummol/l. The minimally invasive center first performed ERCP examination and found that the cause of biliary obstruction was not biliary tract injury. The patient’s jaundice was significantly relieved, the liver function indexes improved, and the patient’s surgical tolerance was significantly improved. After CTA and other examinations, the patient was diagnosed with bile duct cancer with portal vein invasion and pancreatic head invasion. Considering the patient’s young age and also the improvement in general status after ERCP to reduce the yellowing, it was decided to perform an extended radical pancreatic head duodenectomy.
