Other imaging findings
Other Imaging Findings
Other imaging findings may include:
MRCP:
- The diagnostic study of choice.
- Secretin-enhanced MRCP use has been increased recently for the early diagnosis of chronic pancreatitis.
- Findings suggestive of chronic pancreatitis may include:
- Calcifications
- Pancreatic duct obstruction
- It involves no radiation risk.
Endoscopic retrograde cholangiopancreatography (ERCP):
- ERCP is usually done when there is no evidence of
- Calcifications on imaging
- Steatorrhea
- Findings diagnostic of chronic pancreatitis may include
- Beaded appearance of the main pancreatic duct
- Ectatic side branches from the main pancreatic duct
- According to Cambridge classification, patients are divided into 3 categories on the basis of ductal changes seen on ERCP
Cambridge classification | Ductal changes seen on ERCP |
---|---|
Cambridge I | Equivocal changes |
Cambridge II | Mild to moderate changes |
Cambridge III | Considerable changes |
Endoscopic ultrasonography:
Pancreatic function tests:
(a) Direct tests:
- Used to assess pancreatic insufficiency in the early course of disease when patient has clinical symptoms but no radiologic findings
- Secretin stimulation test is considered the gold standard functional test for diagnosis of chronic pancreatitis. The observation that bi-carbonate production is impaired early in chronic pancreatitis has led to the rationale of use of this test in early stages of disease.
(b) Indirect tests:
- Used to assess the complications of chronic pancreatitis
- Not sensitive to assess pancreatic insufficiency in the early course of disease
