Heterogeneity Analysis of Moderately Severe Acute Pancreatitis Based on the Revised Atlanta Classification / 胃肠病学

Background: Recent studies showed that the clinical outcome of moderately severe acute pancreatitis (MSAP) are different among different subgroups. Aims: To further subdivide MSAP, and explore the heterogeneity of MSAP subgroups. Methods: A retrospective analysis was performed on patients with acute pancreatitis (AP) from January 2016 to December 2020 at Northern Jiangsu People’s Hospital, including 538 patients with mild acute pancreatitis (MAP) and 461 patients with MSAP. MSAP patients were divided into four groups according to local complication and transient organ failure (TOF), including single acute peripancreatic fluid collection (APFC) without TOF group (group A), multiple APFC without TOF group (group B), other local complication without TOF group (group C) and TOF group (group D). The baseline data and the severity of AP among the four subgroups were compared. Meanwhile, the severity of disease between group A and MAP patients was also compared. Logistic regression analysis was used to evaluate the risk factors of MSAP. Results: Patients in group D were older than those in group A (P<0.05). There were statistically significant differences in different scoring systems among the four subgroups (P<0.05). The proportions of APACHE Ⅱ≥8, Glasgow≥3 and BISAP≥3 in group D were significantly higher than those in the other three groups (P<0.05). There were significant differences in levels of Ca

Acute Pancreatitis Classification Working Group published Classification of Acute Pancreatitis-2012:Revision of the Atlanta Classification and Definitions by International Consensus in 2012,which redefined the diagnosis,severity,local complication,local infection of acute pancreatitis (AP).Under the guidance of revised Atlanta classification (RAC),the constituent ratio of severe acute pancreatitis (SAP) decreases significantly,which is between 3.7％ ～ 25.4％,and less than 10.0％ is reported in most researches.The mortality of SAP is between 10.0％ ～ 52.9％,and more than 20％ is observed in most publications.The constituent ratio of mild severe acute pancreatitis (MSAP) is between 10.9％ ～ 40.1％,the mortality is between 0 ～ 4.8％,and the incidence rate of organ failure is between 4.6％ ～ 34.0％.The percentage of patients with SAP who need ICU care and surgery intervention is higher than that of MSAP,and the total hospital stay of SAP are longer than that of MSAP.RAC could better reflect the severity and predict the outcome of AP than Atlanta classification published in 1992,but RAC also has some potential limitations.For example,the “local infection” is not included in this classification.This paper veviewed the relavent issues.
