Core Tip

Core Tip: For patients with unresectable middle to low level malignant biliary obstruction, percutaneous transhepatic biliary drainage has been widely used in clinical practice. The selection of the approach and whether different approaches will affect the difficulty of puncture surgery, as well as intraoperative and postoperative complications, have not been discussed in detail. This study compared the clinical efficacy of two different puncture pathways in the treatment of middle and low level biliary obstruction. The authors found that the clinical efficacy of patients undergoing percutaneous left liver puncture was superior to that of patients undergoing percutaneous right liver puncture.
