OBJECTIVE: We described the entity moderately severe acute pancreatitis (MSAP), characterized by local complications (LCs) without organ failure (OF). The aim of this study was to validate MSAP. METHODS: We classified a prospectively collected cohort of 137 acute pancreatitis patients admitted to Mayo Clinic Hospitals into (a) severe acute pancreatitis (SAP; n = 15), presence of OF with/without LCs; (b) MSAP (n = 27), presence of LCs without OF; and (c) mild acute pancreatitis (MAP; n = 95), no OF and LCs. Primary outcomes were need for intensive care unit (ICU) care, total ICU days, total hospital stay, need for interventions, and death. RESULTS: Scores in the Acute Physiology and Chronic Health Evaluation II during admission were significantly different among the 3 groups (MAP vs MSAP, P = 0.02; MSAP vs SAP, P = 0.001); scores in the systemic inflammatory response syndrome during admission were similar between MAP and MSAP. Compared with patients with MAP, patients with MSAP had a significantly longer hospital stay (4 [3.0-7.0] vs 6 [4.0-18.0] days). Compared with those with SAP, a significantly smaller proportion of patients with MSAP required ICU care (12% vs 80%); total hospital stay and need for interventions were similar (6 [4.0-18.0] vs 21 [11.8-27] days and 44% vs 33%, respectively). None of the MSAP patients died compared with 40% from the SAP group. CONCLUSIONS: We have validated MSAP as an exclusive entity.
