Synchronous biliary and duodenal malignant obstruction is a challenging endoscopic scenario in patients affected with ampullary, peri-ampullary, and pancreatic head neoplasia. 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.

Cholangiocarcinoma(CCA) is a malignant tumour that arises from biliary epithelium at any portion of the biliary *** is currently classified as intra-hepatic or extra-hepatic CCA(EH-CCA).Recent evidences suggest that intra-hepatic CCA(IH-CCA) and EH-CCA are biologically different cancers,giving further support to a number of recent epidemiological studies showing large differences in terms of incidence,mortality and risk *** purpose of this manuscript is to review recent literature dealing with the descriptive epidemiology and risk factors of CCA with a special effort to compare IH-with EH-CCA.
