PROGNOSIS FOR SECONDARY PERITONITIS OUTCOME

Objectives. To develop a new system for predicting the outcome of secondary peritonitis and analyze its accuracy in comparison with the most common analogous systems. Methods. The study is based on the analysis of treatment results in patients (n=352) with secondary peritonitis. At admission sepsis was diagnosed in 15 (4.3%) patients, septic shock - in 4 (1.1%) persons. There were the following main causes of death in the mortality structure: purulent intoxication and/or sepsis - 51 cases (87.9%), cancer intoxication - 4 (6.9%) cases, acute cardiovascular failure - 3 cases (5.2%). The efficacy of the Mantheim Peritoneal Index (MPI), WSES prognostic score, APACHE-II scale, gSOFA score and Peritonitis Prediction System (PPS) developed by the authors were analyzed. The likelihood of the effect of 85 clinical and laboratory parameters on the outcome of patients with secondary peritonitis using nonparametric methods of statistical research (Fisher’s test, Mann-Whitney test, Chi-square with Yates correction) have been analyzed. Criteria predictively associated with lethal outcome (p
