Background and aims Tertiary peritonitis is a severe persisting intra-abdominal infection and associated with high mortality. The aim was to find significant risk factors for mortality and tertiary peritonitis including the Mannheim Peritonitis Index (MPI), the Acute Physiology and Chronic Health Evaluation (APACHE) II score, and a sumscore of both. Materials and methods In this retrospective single-center cohort study, 122 patients were treated at the Surgical Department of a University Hospital. Results Sixty-nine patients (56.6%) developed tertiary peritonitis. Nineteen patients (27.5%), who suffered from tertiary peritonitis, died in contrast to eight patients (15.1%) with secondary peritonitis (P=0.101). Patients with tertiary peritonitis had significantly higher APACHE II (P Conclusion Prognostic scores besides age and fungal infections are risk factors for mortality and help to differentiate between secondary and tertiary peritonitis. The combination of prognostic scores is comparable to the APACHE II and superior compared to the MPI in regard to detection of tertiary peritonitis.
