	1	结肠直肠癌术后POSSUM、P-POSSUM及结肠直肠POSSUM预测术后病死率的比较显示文摘PURPOSE:POSSUM(Physiologic and Operative Severity Score for enumeration of Morbidity &Mortality)and P-POSSUM have been validated as scoring tools for the prediction of postoperative complications in general surgical patients.More recently a colorectal-specific POSSUM has been developed for mortality prediction.This study was designed to evaluate and compare the accuracy for mortality prediction of POSSUM,P-POSSUM,and colorectal POSSUM after major and complex major colorectal procedures.METHODS:The relationship between the observed and expected morbidity and mortality was examined in 347 consecutive patients(321 elective,26 urgent)undergoing amajor or complex major colorectal resection using POSSUM,P-POSSUM,and Colorectal POSSUM.The accuracy of using these scoring tools to predict mortality was assessed using Receiver Operator Characteristic curve analysis.RESULTS:A total of 347 consecutive patients(median age,69(range,34-92)years)were assessed.Seventy-one patients(20.5 percent)suffered a postoperative complication and 15 patients(4.3 percent)died.The observed∶expected POSSUM ratio for morbidity was 0.71 and mortality 0.68.The area under curve from Receiver Operator Characteristic curve analysis for POSSUM was 0.752.The observed∶expected mortality ratio for P-POSSUM was 0.71,and the area under curve from Receiver Operator Characteristic curve analysis was 0.749.The observed∶expected mortality ratio for colorectal POSSUM was 0.75,and the area under the curve from Receiver Operator Characteristic curve analysis was 0.781.CONCLUSIONS:Colorectal POSSUM provides comparable prediction of mortality risk after colorectal resection compared with POSSUM and P-POSSUM.
