Abstract

Purpose: Although EUS-guided hepaticogastrostomy (EUS-HGS) with a covered self-expandable metal stent (SEMS) is a useful procedure, it is associated with severe adverse events, including stent migration. We, therefore, developed an intra-conduit release method, and investigated whether the technique yields a safer and more stable procedure. Methods: The intra-conduit release method is a procedure to release the SEMS in the working channel conduit of the scope for anchoring between the liver and stomach to avoid stent migration. Forty-three patients who underwent EUS-HGS at two high-volume centers in Japan were enrolled in this retrospective study, and the safety and usefulness of this method were evaluated retrospectively. Results: The intra-conduit release method was applied in 36 cases. The technical success rate of EUS-HGS with the intra-conduit release method was significantly higher in comparison with the conventional method. Additionally, the rate of early adverse events was significantly lower than that for the conventional method. Conclusion: The intra-conduit release method during EUS-HGS is useful for a stable procedure that avoids early adverse events.
