Objectives

Narrative objectives1

To evaluate the non-inferiority of the 22-gauge needle puncture approach compared with the 19-gauge needle puncture approach in EUS-guided hepaticogastrostomy/hepaticojejunostomy (EUS-HGS/HJS) for patients with biliary obstruction unsuitable for or refractory to transpapillary biliary drainage, using technical success rate as the primary endpoint.

Assessment

Primary outcomes

Technical success rate of EUS-HGS/HJS assessed at the completion of the procedure.

Key secondary outcomes

1.Procedure time (time from needle insertion through the echoendoscope to successful stent deployment)
2.Incidence and types of procedure-related adverse events within 30 days after the procedure
