文摘Pancreatic exocrine insufficiency(PEI)is related to decreased pancreatic enzyme availability and/or activity(1).Multiples underlying mechanisms can cause PEI,such as loss of functioning parenchyma(chronic pancreatitis,pancreatic resections,pancreatic cancer...),decreased secretion despite intact parenchyma(obstruction of the pancreatic duct,decreased endogenous stimulation,intraduodenal inactivation of pancreatic secretions),and asynchrony(gastric resections,Roux-en-Y gastric by-pass)(1).
