1127 COMBINED ENDOSCOPIC ULTRASOUND (EUS), ENDOSCOPIC PANCREATIC FUNCTION TESTING (EPFTS) AND DYNAMIC EUS DUCTAL EVALUATION BEFORE AND AFTER HUMAN SECRETIN STIMULATION FOR THE DIAGNOSIS OF EXOCRINE PANCREATIC INSUFFIENCY (EPI) AND CHRONIC PANCREATITIS (CP)

Abstract

The diagnosis of EPI and CP is difficult and often uses EUS and ePFTs. The use of EUS and ePFTs at a single endoscopy and the use of dynamic EUS (change in diameter of main pancreatic duct, MPD) have not been evaluated.
