Grade II acute pancreatitis. (A) CT scan at level of the pancreatic head obtained within a day of onset shows fluid collection spreading into the RMP (white diamonds), indicating Grade I pancreatitis. (B) CT scan at the same level as in panel A obtained on the day following admission shows extension of the fluid collection not only into the RMP (white diamonds) but also into the LCP (black triangles) and RRP (white triangles), indicating progression to Grade II pancreatitis. APS: anterior pararenal space, CIP: combined interfascial plane, CP: connecting passageway between the RRP and SFP, K: kidney, LCP: lateroconal plane, PM: psoas muscle, PPS: posteriorpararenal space, PRS: perirenal space, PS: presacral space, PV: prevesical space, QLM: quadratus lumborum muscle, RMP: retromesenteric plane, RRP: retrorenal plane, SFP: subfascial plane, TF: transversalis fascia, U: ureter, I: Grade I, II: Grade II, III: Grade III, IV: Grade IV and V: Grade V.

14 Objective: This study aimed to provide a classification system for acute pancreatitis by applying the principle that the disease spreads along the retroperitoneal interfascial planes. 15 16 Materials and methods: Medical records and computed tomography (CT) images of 58 patients with acute pancreatitis treated between 2000 and 2005 were reviewed...
