Conclusion
AP is an acute inflammatory disease of the pancreas caused by inappropriate intracellular activation of proteolytic enzymes with subsequent autodigestion of pancreatic tissue,
interstitial fat necrosis and necrotizing vasculitis.
The CTSI and the Modified CTSI are the most common grading systems.
They categorize the disease in mild,
moderate or severe AP using pancreatic complications only for the first or both pancreatic and extrapancreatic complications of the disease.
The RAC introduced new terminology to better characterize the morphologic and imaging features of necrotizing pancreatitis and its complications.
Imaging findings are also key determinants in guiding management.
It categorizes AP as IEP or necrotizing pancreatitis and the acute collections are referred to APFCs or as ANCs,
depending on the absence or presence,
respectively,
of necrosis.
These collections evolve toward chronic collections and are called respectively pseudocysts or WON.
All four types of collection can be sterile or infected.
