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.

Peripheral nerve injury (PNI) remains a challenging area in regenerative medicine. Nerve guide conduit (NGC) transplantation is a common treatment for PNI, but the prognosis of NGC treatment is unsatisfactory due to 1) neuromechanical unmatching and 2) the intra-conduit inflammatory microenvironment (IME) resulting from Schwann cell pyroptosis and inflammatory-polarized macrophages. A neuromechanically matched NGC composed of regenerated silk fibroin (RSF) loaded with poly(3,4-ethylenedioxythiophene): poly(styrene sulfonate) (P:P) and dimethyl fumarate (DMF) are designed, which exhibits a matched elastic modulus (25.
