Transhepatic Cholangiography and Biliary Drainage: Basic Concepts and Technique

Abstract Percutaneous transhepatic biliary procedures are essential for managing a variety of hepatobiliary conditions, particularly when endoscopic retrograde cholangiopancreatography is not feasible or has failed, or when patients are unstable. This review article provides a comprehensive overview of the indications, contraindications, and procedural steps for biliary puncture, focusing on techniques such as percutaneous transhepatic biliary drainage (PTBD) and percutaneous cholecystostomy. We also address strategies for accessing minimally dilated biliary systems and performing bedside PTBD. The article highlights the increasing demand for these interventions due to rising incidences of biliary diseases such as gallbladder cancer and cholangiocarcinoma, as well as complications arising from previous surgeries. Furthermore, we discuss common and life-threatening complications associated with these procedures, including biliary leaks, hemorrhage, and sepsis, and provide guidance on effective management strategies. Understanding these procedures and their potential complications is crucial for optimizing patient care and outcomes in complex biliary conditions.
