Mannheim Peritonitis Index and APACHE II--prediction of outcome in patients with peritonitis.

Background: Early prognostic evaluation of patients with peritonitis is desirable to select high-risk patients for intensive management and also to provide a reliable objective classification of severity and operative risk. This study attempts to evaluate the use of scoring systems such as Acute Physiological and Chronic Health Evaluation score (APACHE II) and Mannheim Peritonitis Index (MPI) in patients with peritonitis.

Methods: A prospective study was conducted using 101 consecutive patients (69 male, 32 female) having generalized peritonitis over a two-year period.
