Background And Aim:
Endoscopic ultrasound (EUS) and EUS-guided fine needle aspiration (FNA) are established as efficient and safe diagnostic modalities. However, the risk of cholangitis after EUS/EUS-FNA (post-EUS cholangitis) in patients who have biliary strictures has not been fully examined.
Methods:
We retrospectively reviewed 136 consecutive inpatients with biliary strictures who received EUS/EUS-FNA at our hospital from April 2012 to September 2017 and evaluated complications that occurred by the next day after EUS/EUS-FNA. Patients with percutaneous biliary drainage, those in whom it was difficult to reach the duodenum, and those receiving concurrent endoscopic retrograde cholangiopancreatography were excluded.
Results:
We included 121 patients (147 cases); 90 patients were malignant. Endoscopic biliary stenting (EBS) with plastic stents had already been performed in 86 cases. Post-EUS cholangitis was observed in 4.1% (6/147). No other EUS-related complications were observed. The incidence of cholangitis with EBS was significantly higher than that in the cases without EBS (7.0% [6/86] vs 0% [0/61], P = 0.042). Biliary enzyme elevation was also identified as a risk factor of cholangitis.
Conclusion:
Endoscopic biliary stenting was identified as a risk factor associated with post-EUS cholangitis in patients with biliary strictures. Endoscopists should pay attention to post-EUS cholangitis, especially in cases with EBS and biliary enzyme elevation.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
