| Background: EUS-guided biliary drainage (EUS-BD) using conventional biliary stents has been successfully performed. However, those stents need prior dilation and have the risk of bile leakage. A novel braided fully covered 6 mm diameter biliary stent (Braided 6) is mounted on 6 Fr delivery system. This thinnest system seemed to allow the insertion of the stent without prior dilation. The aim of this study was to evaluate the efficacy of the novel stent for one-step EUS-BD. Method: The retrospective study included the patients who underwent EUS-BD with the novel stent between December 2018 and February 2019. Result: A total of seven patients, 5 pancreatic and 2 gastric cancers, were enrolled in this study. None of the patient had acute cholangitis. Four EUS-HGS, 2 EUS-HJS and 1 EUS-CDS were performed. Both technical and clinical success rate were 100%. All stents were successfully inserted without prior dilation. The median time for improvement of jaundice was 3 days (range 1-7). Although there was no acute serious adverse event, stent obstruction (n=1) and stent migration (n=1) occurred during the follow-up period. Conclusion: This study suggested that one-step EUS-BD with the novel stent may have high technical and clinical success rates. Further evaluation of this stent for EUS-BD is warranted. |
