Prognostic factors of critical acute pancreatitis: A prospective cohort study

Abstract

BackgroundPatients with critical acute pancreatitis (CAP) have the highest risk of mortality. However, there have been no studies specifically designed to evaluate the prognostic factors of CAP. Aims & methodsThis was a prospective observational cohort study involving patients with CAP. Three aspects including organ failure, (peri)pancreatic necrotic fluid cultures and surgical interventions were analyzed specifically to identify prognostic factors. ResultsOf the 102 consecutive patients with CAP, 83 patients (81.4%) received step-up surgical treatment, the mortality of the step-up group was 25.3% (21/83). 19 patients (18.6%) underwent step-down surgical treatment, the mortality of the step-down group was 57.9% (11/19). Overall mortality in the whole cohort was 31.4% (32/102). Multivariate analysis of death predictors indicated that multiple organ failure (MOF) (OR = 5.3; 95% CI, 1.5–18.2; p = 0.008), long duration (≥5 days) of organ failure (OR = 6.4; 95% CI, 1.2–54.3; p = 0.029), multidrug-resistant organisms (MDROs) infection (OR = 4.6; 95% CI, 1.3–15.8; p = 0.013), OPN (OR = 3.7; 95% CI, 1.5–8.8; p = 0.004) and step-down surgical treatment (OR = 3.5; 95% CI, 1.2–10.1; p = 0.019) were significant factors. ConclusionAmong patients with CAP, MOF, long duration (≥5 days) of organ failure, MDROs infection, OPN and step-down surgical treatment were identified as the predictors of mortality.
