Surgical bypass is no longer the gold-standard therapy for these patients, as simultaneous endoscopic biliary and duodenal stenting is currently a feasible and widely used technique, with a high technical success in expert hands. In recent years, endoscopic ultrasonography(EUS) has evolved from a diagnostic to a therapeutic procedure, and is now increasingly used to guide biliary drainage, especially in cases of failed endoscopic retrograde cholangiopancreatography(ERCP). The advent of lumen-apposing metal stents(LAMS) has expanded EUS therapeutic options, and changed the management of synchronous bilioduodenal stenosis. The most recent literature regarding endoscopic treatments for synchronous biliary and duodenal malignant stenosis has been reviewed to determine the best endoscopic approach, also considering the advent of an interventional EUS approach using LAMS.展开更多
