Abstract

BACKGROUND/PURPOSE Endoscopic transpapillary re-intervention (ETP-RI) after multiple self-expandable metallic stent (SEMS) placement for unresectable malignant hilar biliary obstruction (MHBO) is challenging, but endoscopic ultrasound-guided biliary drainage (EUS-BD) could be an alternative following failed ETP-RI. We investigated appropriate re-intervention (RI) methods in MHBO after multiple SEMS placement and evaluated RI with EUS-BD (EUS-RI) benefits following ETP-RI failure. METHODS Patients requiring RI after multiple SEMS placement for MHBO between October 2017 and April 2021 were enrolled. Patients' characteristics, metallic-stent type, stent-placement configuration, overall survival, stent patency, re-intervention results, and re-intervention technical and clinical success rates were reviewed. RESULTS Forty-nine patients underwent ETP-RI for MHBO. ETP-RI's technical success rate was 69.4%. Of 15 failed ETP-RI cases, all underwent EUS-RI, achieving technical and clinical success rates of 86.7% and 100%, respectively. Time to recurrent biliary obstruction (TRBO) after RI was significantly different between EUS-RI and ETP-RI (212 vs 84 days; P = .01). On multivariate analysis, EUS-RI was the only factor associated with TRBO (odds ratio: 4.48; 95% confidence interval: 1.01-19.91; P = .04). Acute pancreatitis and bile peritonitis were present in 6.1% of ETP-RI and 13.3% of EUS-RI cases, respectively; both improved conservatively. CONCLUSIONS EUS-RI was effective and safe in difficult ETP-RI cases after multiple SEMS placement for MHBO.

Abstract

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.
