The diagnostic test or imaging that would be the most useful in diagnosing chronic pancreatitis is ERCP.
ERCP, short for Endoscopic Retrograde Cholangiopancreatogram, is a procedure used to diagnose problems in the gallbladder, liver, bile ducts, and pancreas. Several things that may be found using ECRP are:
- Tumors
- Blockages or narrowing in the pancreatic ducts
- Blockages or stones in the bile ducts
- Fluid leakage
- Infection
Since the client in the case above is suspected of chronic pancreatitis, which is a problem with the pancreas, it would make sense if the nurse finds ECRP as the most useful test to diagnose whether the client really does have chronic pancreatitis or not.
