Malignant biliary obstruction commonly caused by pancreatic adenocarcinoma, cholangiocarcinoma and other etiologies like gallbladder carcinoma, hepatocellular carcinoma, lymphoma, and metastasis to regional solid organs and lymph nodes. Pancreatobiliary cancers generally present with jaundice, weight loss, and anorexia with significant impact on quality of life, morbidity, and mortality. The primary goal of diagnosis and management is curative resection but it's difficult due to local invasion and distant metastases at the time of clinical presentation. Biliary decompression helps to reduce symptoms and improve quality of life in patients with malignant biliary obstruction. Endoscopically placed stents have become the standard of care for non-surgical biliary drainage due to their minimal invasiveness compared to percutaneous drainage. The standard treatment of obstructive jaundice has been ERCP with biliary stent placement with high success rate in expert hands and low frequency of adverse events. Endoscopic ultrasound-guided biliary drainage (EUS-BD) has been increasingly used in patients who underwent failed ERCP. EUS-BD can be performed in several ways, choledochoduodenostomy (CDS), hepaticogastrostomy (HGS), antegrade (AG) procedure, and rendezvous (RV) technique.
