Thus, the present study was conducted to identify the risk factors of IPN secondary to SAP. METHODS： The clinical data of patients with SAP were retrospectively analyzed. Univariate and multivariate logistic regression analyses were sequentially performed to assess the associations between the variables and the development of IPN secondary to SAP. A receiver operating characteristic（ROC） curve was created for each of the qualified independent risk factors. RESULTS： Of the 115 eligible patients, 39（33.9%） progressed to IPN, and the overall in-hospital mortality was 11.3%（13/115）.The early enteral nutrition（EEN）（P=0.0092, OR=0.264）, maximum intra-abdominal pressure（IAP）（P=0.0398, OR=1.131）and maximum D-dimer level（P=0.0001, OR=1.006） in the first three consecutive days were independent risk factors associated with IPN secondary to SAP. The area under ROC curve（AUC） was 0.774 for the maximum D-dimer level in the first three consecutive days and the sensitivity was 90% and the specificity was 58% at a cut-off value of 933.5 μg/L; the AUC was 0.831 for the maximum IAP in the first three consecutive days and the sensitivity was 95% and specificity was 58%at a cut-off value of 13.5 mm Hg. CONCLUSIONS： The present study suggested that the maximum D-dimer level and/or maximum IAP in the first three consecutive days after admission were risk factors of IPN secondary to SAP; an EEN might be helpful to prevent the progression of IPN secondary to SAP.展开更多
