自1992年亚特兰大关于急性胰腺炎的分类及指导意见发表以来，经20年实践检验，该分类对急性胰腺炎局部并发症的分类及定义存在不足，各情况多有交叉，不够确切。在与每一具体情况相对应的诊断、治疗及预后方面，关联性不强。近年来不断有文献对亚特兰大分类进行补充及修订，目前多将胰腺炎局部并发症分为4种类型，即急性胰周液体积聚、假性囊肿、急性坏死后胰腺及胰周液体积聚和包裹性胰腺坏死，上述修订更加切合病理生理及临床诊疗实际，也更具有指导性。

Recongnition of the diagnosis and treatments of local complications in acute pancreatitis        YANG Yin-mo. Department of Surgery, Peking University First Hospital, Beijing 100034, China
Abstract    Local complications often occur in acute pancreatitis (AP) and have been defined by the Atlanta Symposium on Acute Pancreatitis in 1992. Two decades since the Atlanta Conference additional experience has brought to light the inadequacy and poor understanding of the terms used by different specialists involved in the care of patients with AP when interpreting imaging modalities and the need for a uniformly used classification system. Recognizing the deficiency, some revisions of the Atlanta classification have been proposed by some research groups. The 4 major subsets of local complications in AP as modified by the research groups' revision are “acute peripancreatic fluid collections”,  “pancreatic pseudocyst”,  “postnecrotic pancreatic/peripancreatic fluid collections” and “walled-off pancreatic necrosis”. Differentiation of one from another is important because management varies with the type of local complications.
