DEFINITION An acute inflammatory process of the pan creas usually associated with sever pain in the upper abdomen in most instances blood levels of pancrea tic enzymes are increased sever acute pancreatitis: organs failure and/or local complications(necrosis, absc ess, psuedocyst

2 DEFINITION • An acute inflammatory process of the pan￾creas usually associated with sever pain in the upper abdomen • in most instances, blood levels of pancrea￾tic enzymes are increased • sever acute pancreatitis: organs failure and/or local complications(necrosis, absc￾ess, psuedocyst)

PATHOLOGY(1) Mild acute pancreatitis(MAP) characterized by interstitial edema associ- ated with inflammatory cell within parench yma, and microscopic parenchyma necro sis can be detectable

3 PATHOLOGY(1) • Mild acute pancreatitis(MAP) characterized by interstitial edema associ￾ated with inflammatory cell within parench￾yma, and microscopic parenchyma necro￾sis can be detectable

PATHOLOGY (2) Sever acute pancreatitis(SAP Sever necrotizing pancreatitis(SNP) macroscopic evidence of either focal or diffuse necrosis and hemorrhage of the pancreatic parenchyma

PATHOGENY AND PATHOGENESIS(4) 6 inflammatory media theory In AP, the leukocytes that appear first in areas of inflammation are neutrophils, then macrophages, monocytes, lymphocytes and other cells. These cells can secrete a lot of inflammatory media (1) platelet activating factor, PAF (2)prostaglandins, PGs
