Acute Pancreatitis XUE Huiping;Pancreatitis is an inflammatory process in which pancreatic enzymes autodigest the gland.;√The gland can sometimes heal without any impairment of function or any morphologic changes. This process is known as acute pancreatitis. √It can recur intermittently, contributing to the functional and morphologic loss of the gland, the pathological change referred to as chronic pancreatitis.;√Acute pancreatitis refers to an attack involving a previously normal pancrease.√Chronic pancreatis is applied to an attack involving a previously, permanently damaged pancrease.;√Acute pancreatitis is an acute inflammatory process of the pancreas, with variable involvement of other regional tissue or remote organ systems.  √ Although pancreatic function and structure usually return to normal, the risk of recurrent attacks is 20 to 50% unless the precipitating cause is removed.  √ The disease includes a broad spectrum of pancreatic disease, which varies from mild parenchymal edema to severe hemorrhagic pancreatitis associated with subsequent gangrene and necrosis. 急性胰腺炎（acute pancreatitis）是指胰酶在胰腺内激活后引起胰腺组织自身消化的急性化学性炎症。 ;A sensible classification system separates pancreatitis into mild and severe disease based on physiologic findings, laboratory values, and radiologic imaging.;Mild pancreatitis is not associated with organ dysfunction or complications, and recovery is uneventful. Severe pancreatitis is associated with decreased function of the pancreas, local and systemic complications, and a complicated recovery. ;√ 轻型急性胰腺炎是指仅有很轻微的脏器功能紊乱，没有明显腹膜炎体征及严重代谢紊乱等临床表现，临床恢复顺利者。该型病理上绝大多数为水肿型胰腺炎，少数也可有胰腺实质坏死。 ;Severe pancreatitis is defined as a local complication and/or organ failure.;√重症急性胰腺炎是指急性胰腺炎伴有脏器功能障碍，或出现坏死、脓肿或假性囊肿等局部并发症，或两者兼有。该型病理上绝大多数为坏死型胰腺炎，但少数情况下水肿型胰腺炎也可表现为重症胰腺炎。 ;Local complications are defined as (1) acute fluid collections;(2) pancreatic necrosis;(3) pancreatic abscess;(4) pancreatic pseudosyst;√ The clinical presentation of acute pancrea
