A One-step Procedure by Using Linear Echoendoscope to Perform EUS-guided Choledochoduodenostomy and Duodenal Stenting in Patients with Irresectable Periampullary Cancer

Abstract Objective: Endoscopic ultrasound-guided choledochoduodenostomy (EUS-CD) has become an alternative method after unsuccessful endoscopic retrograde cholangiopancreatography (ERCP) treatment. We present a case series study and its feasibility by using only a linear therapeutic channel echoendoscope to create both a biliary-enteral fistula and anatomic enteral recanalization. Methods: We presented seven cases of unresectable periampullary cancer with both biliary and duodenal obstruction. In these cases, the EUS-guided technique might be an alternative to double stenting (biliary and enteral) in the same procedure
