[Early prognostic risk factors in acute pancreatitis: study of a representative population from Peru].

Thirty-one patients with acute pancreatitis were prospectively evaluated using the Early Prognostic Risk Factors of Ranson and Bank & Wise, in order to assess severity of that condition. The purpose was to determine the usefulness of such factors as clues to orient diagnosis and treatment of acute pancreatitis, particularly in the most severe clinical forms; and the factibility of using them in our setting. The presence of 4 or more of Ranson's and/or 1 or more of Bank & Wise Factors fulfilling positive criteria, identified the patients with a high risk of complications and mortality. Hypocalcemia, leucocytosis and hyperuricemia were the most frequent findings in this group. The development of Early Objective Prognostic Risk Factors in acute pancreatitis, as a clinical concept, has improved the management of these patients. It allows to establish diagnosis and therapeutics upon objective basis.
