Popis: To evaluate the feasibility and safety of endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) without fistula dilation using a novel self-expandable metal stent (SEMS).This retrospective study examined patients who underwent EUS-CDS for malignant distal biliary obstruction between October 2017 and May 2021 at the National Cancer Center, Japan. The primary outcome was a technical success without fistula dilation. Secondary outcomes were the overall technical success, clinical success, adverse events (AEs), procedure time, recurrent biliary obstruction (RBO), and time to RBO (TRBO).Forty-one patients were enrolled; 31 patients underwent EUS-CDS with fistula dilation using a conventional SEMS with 7.5-8.5-Fr delivery system (conventional SEMS group), and 10 patients underwent EUS-CDS without fistula dilation using the novel SEMS with a 5.9-Fr delivery system (novel SEMS group). In the novel SEMS group, the rate of technical success without fistula dilation was 90%. There were no differences in overall technical success (100% vs. 97%,EUS-CDS without fistula dilation using the novel SEMS with a 5.9-Fr delivery system is technically feasible, straightforward, quick, and safe.
