    Aims EUS-guided transmural drainage (EUS-TD) of the bile duct and gallbladder (GB) using a lumen-apposing metal stent (LAMS) has been established as one of the effective alternative procedure. Moreover, as the electrocautery-enhanced delivery system enhanced LAMS has been introduced, one-step EUS-biliary drainage (BD) is facilitated in a recent. In this study, we evaluated the feasibility of the novel electrocautery-enhanced LAMS for one-step EUS-guided choledochoduodenostomy (CDS) or GB drainage (GBD).

    Methods Patients who had failed ERCP for the drainage of malignant distal biliary obstruction or patients with acute cholecystitis by malignant biliary stricture or high risk for surgery were enrolled prospectively. EUS-CDS or GBD were performed using a fully covered LAMS with an electrocautery-enhanced device (Niti-S HOT SPAXUS; Taewoong Medical Co., Ltd., Ilsan, South Korea). Primary outcome is technical success of EUS-CDS and EUS-GBD.

    Results Among 14 enrolled patients (median age, 70.5 years; 10 males), EUS-GBD and EUS-CDS were performed in 8 patients and 6 patients, respectively. Overall technical success rate of EUS-BD was 92.9% (13/14 patients) with one technical failure in EUS-GBD. All 13 patients successfully undergoing EUS-BD showed clinical success (100%). Median procedure time of EUS-GBD and CDS were 13 min and 7 min, respectively. Adverse event was observed in 2 patients; peritonitis responding to antibiotics with EUS-GBD (n=1), abdominal pain with EUS-CDS (n=1).

    Conclusions One-step EUS-CDS and GBD using a novel electrocautery-enhanced LAMS is feasible with high technical success rate and safety.
