Ikezawa K, Shigekawa M, Yamai T, et al. - Given that endoscopic ultrasound (EUS) and EUS‐guided fine needle aspiration (FNA) are established as efficient and safe diagnostic modalities, researchers sought to analyze the risk of cholangitis after EUS/EUS‐FNA (post‐EUS cholangitis) in patients who have biliary strictures. Retrospectively, 136 consecutive inpatients with biliary strictures who received EUS/EUS‐FNA at the hospital from April 2012 to September 2017 were examined and complications that occurred the following day after EUS/EUS-FNA were evaluated. One hundred twenty-one patients (147 cases) were included; 90 patients were malignant. Endoscopic biliary stenting (EBS) was identified in patients with biliary strictures as a risk factor associated with post-EUS cholangitis. Post-EUS cholangitis, particularly in cases with EBS and biliary enzyme elevation, should be considered by endoscopists.
