Abstract

MPI is a perforation specific score which allow prognostication of patients with hollow viscous perforation peritonitis. We aimed to study the role of Mannheim Peritonitis Index to predict the outcome in patients with hollow viscous perforation and to evaluate the prognostic value Of MPI score in patients with hollow viscous perforation. Methodology- This study was conducted as a prospective cohort study on Patients with peritonitis due to hollow viscous perforation at Department of Surgery, People’s Hospital Bhopal, during the study period of 18 months. MPI score was calculated for each patient and patients were followed till their hospital stay and outcome was assessed in terms of Mortality and morbidity. Results- This study was conducted on a total of 50 patients with mean age of 40.02±12.964years and we reported male predominance in our study for peritonitis with male: female ratio of 2.13:1. Mean Mannheim peritonitis index (MPI) score was suggestive of mild, moderate and severe peritonitis in 46%, 42% and 12% cases respectively. We observed a statistically significant association of severe peritonitis with shock, acute renal failure and mortality (p<0.05). The area under the curve (0.806; 95% CI- 0.625-0.987) showed MPI to be a good predictor of outcome (p<0.05). Conclusions-Mannheim Peritonitis Index is a simple, rapid and cost effective tool based upon the clinical and preoperative parameters, which helps in predicting the mortality in perforation peritonitis with good accuracy. MPI is sensitive and specific indicator of mortality with few false positive and false negative cases. Increase in MPI helps in not only stratification of patients as mild, moderate and severe peritonitis but also predict the mortality in such cases.
