A novel and challenging EUS-guided bridging technique for hilar cholangiocarcinoma (Bismuth IV) after total...

The incidence of hilar cholangiocarcinoma is (1-2) / 100,0001. Due to the high location of obstruction, the treatment of hilar cholangiocarcinoma is complicated, especially for patients with gastrointestinal surgery. The traditional ERCP technique is to find a way to place more stents to treat obstructive jaundice. When ERCP fails, (Percuteneous transhepatic cholangial drainage, PTCD) is often chosen, but the effect is not ideal. The reason is that patients do not want to carry a drainage tube, which affects the quality of life of patients. Secondly, PTCD technology is bile external drainage technology, which will affect the balance of water and electrolytes in the patient's body, and the patient's appetite will also decrease. Here, we provide a bridge technique of EUS-BD to solve the problem of simultaneous drainage of left liver and right liver with a stent, in order to provide a new treatment idea for endoscopists.
