Objective: Whether metal stents (MS) or plastic stents (PS) yield better outcomes for malignant biliary obstruction in endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is controversial. We aimed to compare outcomes of initial EUS-HGS performed with MS or PS.
Methods: In this single-center retrospective study, we included patients (MS/PS groups: n = 151/72) with unresectable malignant biliary obstruction and performed multivariable analysis.
Purpose: To evaluate the risk factors of non-diagnostic results based on cause of error in liver tumor biopsy.
Materials And Methods: This single-institution, retrospective study included 843 patients [445 men, 398 women; median age, 67 years] who underwent a total of 938 liver tumor biopsies between April 2018 and September 2022. An 18-G cutting biopsy needle with a 17-G introducer needle was used.
