Endoscopic Ultrasound Guided Choledocoduodenostomy With the Lumen Apposing Metal Stent [Axios® Stent]

Endoscopic Ultrasound Guided Choledocoduodenostomy With the Lumen Apposing Metal Stent [Axios® Stent]

Endoscopic Ultrasound (EUS) guided biliary drainage is indicated in case of impossibility or failure of classic biliary drainage by endoscopic retrograde cholangio-pancreatography (ERCP). Recently the investigators reported a good efficiency of EUS guided choledocoduodenostomy using the HOT-AXIOS device (Electrocautery enhanced lumen apposing metal stent) in a retrospective multicentric study. Utilization of the recommended technique (direct punction with the HOT AXIOS using a pure cut current + using a 6 mm Stent) was the only predicting factor of clinical success. The investigators reevaluate this procedure one year after in the same centers.

Inclusion Criteria:

• patients with tumoral obstruction of the distal biliary tract that have been treated by an EUS-CDS with a electrocautery enhanced LAMS

Exclusion Criteria:

• < 18 years old
