ERCP cannulation
The process of selectively inserting a catheter into the bile duct or pancreatic duct during endoscopic retrograde cholangiopancreatography.
Full Definition
ERCP cannulation represents one of the most technically challenging aspects of therapeutic endoscopy, requiring precise manipulation of a guidewire and catheter through the ampulla of Vater into either the biliary or pancreatic ductal systems. Success depends on proper patient positioning, duodenoscope manipulation, and understanding of anatomical variations. Failed cannulation may require alternative techniques such as precut sphincterotomy, needle-knife access, or conversion to percutaneous approaches.
Usage
Usage note: ERCP is typically not spelled out when discussing cannulation specifically.
