[Prospective study of procalcitonin as a diagnostic marker of the severity of secondary peritonitis].

Introduction: It has been shown that procalcitonin (PCT) is a good marker for sepsis as the more severe the infection the higher the plasma levels. The Mannheim peritonitis index (MPI) is very effective in assessing the prognosis of secondary peritonitis. The aim of this study is to find out whether there is any correlation between preoperative PCT levels and the postoperative MPI, as well as the prognostic value of preoperative PCT levels.
