Overview

Other imaging findings may include MRCP, ERCP, and endoscopic ultrasonography. MRCP is the diagnostic study of choice. MRCP findings suggestive of chronic pancreatitis may include calcifications and pancreatic duct obstruction. ERCP findings diagnostic of chronic pancreatitis may include beaded appearance of the main pancreatic duct and ectatic side branches from the main pancreatic duct. Presence of stones is the most predictive finding seen on endoscopic ultrasonography. Other findings suggestive of chronic pancreatitis may include visible side branches, cysts, lobularity, an irregular main pancreatic duct, hyperechoic foci, dilation of the main pancreatic duct and hyperechoic margins of the main pancreatic duct. Pancreatic function tests may include direct tests such as secretin stimulation tests and indirect tests.

Endoscopic retrograde cholangiopancreatography (ERCP):

• ERCP is usually done when there is no evidence of
  • Calcifications on imaging
  • Steatorrhea

Endoscopic ultrasonography (EUS):

EUS findings suggestive of hereditary pancreatitis may include:

• Visible side branches
• Cysts
• Lobularity
• An irregular main pancreatic duct
• Hyperechoic foci and strands
• Dilation of the main pancreatic duct
• Hyperechoic margins of the main pancreatic duct
