Sumario: | BACKGROUND AND AIM: The advent of endoscopic ultrasound‐guided biliary drainage (EUS‐BD) has provided an inimitable alternative for gaining biliary access in patients who fail conventional endoscopic drainage. The antimigratory features of the partially covered metal stent (PCMS), namely, the flange head and uncovered portion of the stent, makes it a valuable option in patients undergoing EUS‐guided hepaticogastrostomy (EUS‐HGS). The aim of the study is to evaluate the clinical outcome of EUS‐BD via the hepaticogastrostomy approach using PCMS in patients with malignant biliary obstruction after failed ERCP. METHODS: This is a single‐center retrospective observational study of patients with malignant biliary obstruction undergoing EUS‐HGS after failed ERCP between January 2018 and May 2019. The end‐point of the study was to assess the technical and clinical success rate, as well as the stent‐ and procedure‐related complications. RESULTS: There were 20 subjects in this study. The average age was 71.8 ± 7.6 years. Most patients were male, 16 (80%). Inaccessible papillae was the most common indication for this procedure, 16 (80%). Technical success was achieved in all patients. The average procedural time was 39.9 ± 1.3 min. Mean preprocedural bilirubin levels were 348.6 ± 28.8 and subsequently decreased to 108.94 ± 37.1 μmol/L at 2 weeks postprocedure. The clinical success rate was 95% (19/20), with one patient requiring percutaneous transhepatic biliary drainage (PTBD). There were no stent‐ or procedure‐related complications reported in this study. CONCLUSION: EUS‐HGS with PCMS is a feasible, effective, and safe alternative for biliary decompression in patients with failed endoscopic retrograde cholangiopancreatography (ERCP). |
