The objective of this study is to evaluate the Mannheim Peritonitis Index (MPI) usefulness for acute generalized peritonitis management in a clinical limited resources context.


This is a prospective study from 1 January to 31 October 2019 including patients admitted to a sub-saharan hospital for acute generalized peritonitis. Perioperative variables and outcomes were considered.


70 patients were included. Mean age was 32.6 ± 14.6 years with a sex ratio of 1.33. The mean time to patients’ hospital admission was 3.9 ± 2.1 days. Most patients had ileal and gastric perforations (27.1% and 18.6%). Twenty six patients (37.1%) developed complications and thirty-day mortality rate was 14.3%. Positive predictive value of MPI was 63.6% and negative predictive value was 83, 8%. Sensitivity of MPI ≥ 26 was 77.8%; Specificity of MPI < 25 was 72.1%.


This experience shows that MPI is a good predictor of morbidity and mortality for patients with acute peritonitis even in a difficult context with few resources and many patients. Identifying the most critical patients, a more careful surgical staff involvement may improve patients outcome.
