Endoscopic Retrograde Cholangiopancreatography Tissue Sampling: When and How?

A 69-year-old man presented with obstructive jaundice. Endoscopic retrograde cholangiopancreatography was performed for biliary tree decompression and diagnostic tissue acquisition. Techniques, indications, methodologic considerations, and interpretation of tissue sampling at endoscopic retrograde cholangiopancreatography in patients with biliary/pancreatic strictures are discussed. This case-based educational presentation focuses on the importance of interdisciplinary communication between endoscopists and pathologists for optimal tissue sampling, interpretation, and diagnostic accuracy.
