Palliative endoscopic biliary drainage for malignant hilar biliary obstruction

Study designs: Systematic Review, Meta-Analysis

Abstract: Malignant hilar biliary obstruction (MHBO) is most commonly caused by cholangiocarcinoma or gallbladder cancer and frequently presents with obstructive jaundice, pruritus, and/or cholangitis. These symptoms impair performance status and delay the initiation of chemotherapy, making biliary drainage essential for both palliation and oncologic treatment. Endoscopic transpapillary biliary stenting via endoscopic retrograde cholangiopancreatography is the standard approach for biliary decompression. In patients with unresectable disease, either plastic or self-expandable metal stents may be used. Optimal outcomes are achieved when drainage encompasses more than 50% of functional liver volume, while atrophic segments should be avoided. When transpapillary access is not feasible or unsuccessful, alternative approaches such as percutaneous transhepatic biliary drainage or endoscopic ultrasound-guided biliary drainage may be considered. Adjunctive therapies, including photodynamic therapy and radiofrequency ablation, are being investigated to enhance local tumor control and prolong stent patency. With continued advances in stent technology, imaging modalities, and endoscopic techniques, the management of MHBO is expected to become increasingly individualized and effective.
