Summary

EUS - guided choledocho-duodenostomy (ECDS) is an established option for bile duct drainage in unresectable malignant distal CBD strictures when endoscopic retrograde cholangiopancreatography (ERCP) fails. However, how primary ECDS compares with ERCP with covered self-expanding metallic stents (CSEMS) in unresectable malignant distal CBD strictures is uncertain.

The aim of the current study is to compare primary ECDS versus ERCP with CSEMS in unresectable malignant distal CBD strictures. We hypothesis that ECDS is associated with a higher 1-year stent patency rate.

Conditions

  • Malignant Biliary Obstruction

Interventions

PROCEDURE

EUS-guided choledocho-duodenostomy

The CBD would be identified by a linear echoendoscope and a suitable puncture site in the bulb of the duodenum would be located. The common bile duct would be punctured with a 19-gauge needle and the position would be confirmed by aspiration of bile and contrast injection. A 0.025" or 0.035" guide wire would be passed through the needle in to the CBD. A fully covered metal stent would then be inserted after track dilation.

PROCEDURE

Endoscopic retrograde cholangiopancreatography with covered metallic stent

After cannulation of the CBD, a cholangiography would be performed to assess the diameter of the CBD, the length and position of the biliary stricture. The endoscopist would decide on the appropriate size of SEMS to be placed. The stents should be visible from the duodenal lumen after deployment.
