Developmental phase	Phase IV

Assessment
Primary outcomes	the accuracy of the diagnostic approach using ERCP-guided TPB and EUS-FNAB according to the type of biliary stricture in patients with suspected MBS
Key secondary outcomes	the accuracy of initial TPB, technical failure and adverse event rates of ERCP-guided TPB and EUS-FNAB

In outcomes field, the entry of just a few words such as "safety" or "efficiency" will not be accepted. Specify the name of outcome measures, including the time when you plan to measure. Usually, only one primary outcome is accepted. Write the other outcomes in "secondary outcomes" field.

Key inclusion criteria	(1) the presence of biliary stricture due to a thickened bile duct wall or pancreatobiliary mass revealed by cross-sectional radiologic images, computed tomography (CT), and/or magnetic resonance imaging (MRI), (2) clinical findings of obstructive jaundice and/or cholangitis, (3) age >18 years, and (4) ability to provide informed consent.
Key exclusion criteria	(1) underlying pancreatobiliary disease without clinical findings suggestive of malignancy (e.g., primary biliary cirrhosis or postoperative biliary stricture), (2) the presence of any contraindication for ERCP, (3) coagulopathy (international normalized ratio >1.5 or platelet count <80,000/mm3 (4) difficulty to perform ERCP due to altered gastrointestinal anatomy or a significant duodenal obstruction.
