Abstract :

Background:Early stratification of peritonitis by scoring system will allow in predicting the possible outcome and providing more critical care services to the serious patients. The objective of the study was to validate the performance of Mannheim Peritonitis Index (MPI) score in patients with secondary peritonitis. Methods: This is a prospective study conducted on 105patients admitted and operated for peritonitis in the department of surgery. Clinical, laboratory, surgical finding, MPI scoring and outcome were recorded on pre–structured format. Collected data were analyzed. Pearson�s chi square test was used as statistical test and considered as showing a significant difference if P was equal or less than< 0.05. Result: The overall mortality and morbidity was 11.42% and 20.95% respectively. The mortality rate of 0%, 38% and 80% were at the MPI score of ≤20,21–29 and >29 respectively. There was strong association between increasing MPI score and mortality (p<0.001).MPI score also influences morbidity and hospital stay (P<0.05).The Receptor operating characteristic (ROC) curve prediction between nonsurvivors and survivors was an excellent with a sensitivity of 50% and a specificity of 98.5% at an MPI of 27 points. Conclusion:The increasing MPI score is strongly associated with outcome of secondary bacterial peritonitis
