title: [Valuation on prognostic factors about secondary acute peritonitis: review of 255 cases].
abstract: Despite advances in diagnosis, surgical treatment, antimicrobial therapy and intensive care support, severe secondary peritonitis remains a potentially fatal affliction. The purpose of this study is to present our experience of postoperative mortality in 255 patients with secondary acute peritonitis between 1998 to 2002. The Mannhein Peritonitis Index score (MPI) was calculated for each patient to predict the peritonitis related in-hospital death. Both literature reviews and our results show a strong correlation between some etiopathogenetic elements (age, origin of sepsis, organ failure, ...) and prognosis. Our patients were classified in three groups according to MPI, one with a score less than 21, another with a score between 21 and 29 and the third one with a score greater than 29. There was no mortality in the first group and there was significantly less mortality in the second group than the third one (P<0.001). While prognosis is influenced by many factors, the intervention time was the same, greater than 24 hours, for all the patients regardless of MPI score. This study suggests that intervention time may be considered the main determinant of mortality in patients with peritonitis. This observation is especially relevant since intervention time is a modifiable prognostic factor whilst many other factors are not.
