Invasion of the intrahepatic bile duct by gallbladder cancer, cholangiocarcinoma of the porta hepatis or bile duct embolism due to hepatocellular carcinoma can lead to fatal jaundice. Most physicians tend to treat such patients negatively in the clinical setting with advanced stages across the board. The most common management method is external drainage via percutaneous hepatic bile duct placement, also known as “PTCD”. This method is simple and has short-term efficacy. However, there is a tendency for the catheter to become obstructed and fall off. Patients with external bile drainage have poor digestive function. The catheter is fixed on the skin outside the body, which causes local pain and interferes with rest and social interaction. These unbearable pains can lead to a significant decrease in the quality of patient survival and an increase in the cost of follow-up treatment. For such patients, as long as there is still a section of tertiary bile duct not invaded by tumor, we can use bile duct jejunal bridge internal drainage can effectively avoid the above-mentioned adverse consequences. It improves the quality of patients’ survival at the later stage and significantly extends their survival time.
