This video demonstrates a case of EUS-guided choledochoduodenostomy, emblematic of the latest cutting-edge technology. A 86-year-old woman with recent abdominal pain and jaundice underwent a CT-scan, which showed an enlarged tumor of the second portion of the duodenum with biliary tree dilatation. Gastroscopy with biopsy confirmed the diagnosis of duodenal adenocarcinoma of the 2nd duodenum. First, endoscopic retrograde cholangiopancreatography (ERCP) failed to achieve biliary drainage because of an inability to cannulate the papilla due to tumor infiltration. EUS-guided hepatogastrostomy (EUS-HGS) was not attempted because the left intra-hepatic bile ducts were minimally dilated (3mm). However, the common bile duct (CBD) was largely dilated (20 mm). A Hot AXIOS™ Stent and Electrocautery Enhanced Delivery System (stent of 8 by 6mm) was advanced through the bulb. Pure cut electrocautery current was then applied, allowing the device to reach the CBD. Next, the distal flange was opened and retracted towards the EUS transducer, and once a biliary and bulbar tissue apposition had been noted, the proximal flange was released. Good drainage of purulent bile was observed and no complications occurred during the procedure and one month afterwards.
