Mortality rate in patients with Secondary Peritonitis in Ain Shams University Hospitals as regard Mannheim Peritonitis Index (MPI) score

Abstract

Abstract Introduction Secondary peritonitis is one of the most common fatal surgical emergencies. The mortality rate is about 20% even in well- equipped places. The outcome can be improved be rapid surgical intervention and intensive care of the patient. Many scoring systems were developed to identify high-risk patients who may need rapid intervention or intensive care. Mannheim Peritonitis Index (MPI) is an easy and specific score for predicting the outcome of secondary peritonitis. Patients and Method It’s an observational prospective study over 50 patients presented with secondary peritonitis to our E.R during the period from January 2018 to June 2018 and patients were followed up for one month. Patients were divided into three groups according to their MPI score, Group I: with MPI score less than 21, Group II: with MPI score between 21 and 29, and Group III: with MPI score more than 29. Results In the present study, Mortality rate was about 24%. Mortality rates in those groups were 0%, 5.5% and 55% respectively which are similar to results of other studies performed in other places. Cut-off value is 28 with sensitivity 91% and specificity 76%. Conclusion MPI score is effective in predicting outcome of patients with secondary peritonitis in our hospitals.
