Diagnostic Value of CT Severity Index and APACHE Ⅱ Score in the Severity of Acute Pancreatitis
Objective To study the computed tomography severity index(CTSI)and the acute physiology and chronic healthy evaluation Ⅱ(APACHEⅡ)on the prognosis of patients with acute pancreatitis(AP).Methods A retrospective analysis of 273 AP patients admitted to our hospital from January to December 2021 was performed to observe their abdominal enhanced CT images.According to CT findings,they were divided into edematous AP and necrotic AP,and CTSI scores were performed according to their images.APACHE Ⅱ score,local complications,death,hospitalization time and ICU stay were calculated within 24 hours after admission.The relationship between CTSI,APACHE Ⅱ score and local complications,death,hospitalization time and ICU stay was analyzed.Results In AP patients,the CTSI score of patients with local complications was higher than that of patients without local complications(P＜0.05).There was no significant difference in APACHE Ⅱ score between patients with and without local complications(P＞0.05).The APACHE Ⅱ score of the dead patients was higher than that of the survival patients(P＜0.05),while,there was no significant difference in CTSI score between dead and surviving patients(P＞0.05).In terms of predicting hospitalization days,the higher the CTSI score and APACHE Ⅱ score,the longer the hospitalization time(r=0.340,0.264).The CTSI score and APACHE Ⅱ score of patients who needed to be transferred to ICU were higher than those of patients who did not need to be transferred to ICU(P＜0.05).Conclusion In patients with acute pancreatitis,CTSI score is superior to APACHE Ⅱ score in evaluating local complications,but inferior to APACHE Ⅱ score in evaluating death.Both CTSI and APACHE Ⅱ scores can predict the length of hospital stay and whether patients are transferred to ICU.
