Mannheim Peritonitis Index

Mannheim Peritonitis Index

A prognostic scoring system used to predict mortality in patients with peritonitis. Long-term survivors have an MPI score of about 20; non-survivors have a score of 33.

Risk factor—Score
• Malignancy—4.
• Pre-op duration of peritonitis—4.
• Age > 50—5.
• Female gender—5.
• Diffuse generalised peritonitis—6.
• Organ failure—7.
• Exudates
   – Clear—0.
   – Cloudy, purulent—6.
   – Faecal—12.

published the Mannheim Peritonitis Index (MPI) based on analysis of possible risk factors in patients of peritonitis.
Patient age, gender, weight, height, American Society of Anesthesiologists (ASA) score, symptoms, time interval between symptom onset and surgery, accompanying diseases, length of hospital stay, operative technique, laboratory findings, site and diameter of perforation, Acute Physiology and Chronic Health Evaluation (APACHE) II and Mannheim Peritonitis Index (MPI) scores, preoperative shock state, morbidity, and mortality were recorded.
The Mannheim peritonitis index (MPI) was developed with incorporated information and discriminant analysis of 17 possible risk factors like age, gender, organ failure, cancer, duration of peritonitis, involvement of colon, extent of spread within the peritoneum, and the character of peritoneal fluid to define risk.
To compare groups, age, gender, comorbidities, ASA score, and Mannheim Peritonitis Index [12] were documented in all patients.
Planned relaparotomy was performed in 153 (67.11%) of the cases, (mean Mannheim peritonitis index score--28.9) and laparostomy--in 75 (32.89%) of the cases, (mean MPI score-33.19).
Gonullu et al19 reported a higher mortality in patients with higher APACHE II (Acute Physiology and Chronic Health Evaluation) and MPI (Mannheim Peritonitis Index) scores; their mortality rate was 43%.
[1,2,3] Many scoring systems have been developed and used successfully to grade the severity of acute peritonitis like, Acute physiology and chronic health evaluation (APACHE) II score, Simplified acute physiology score (SAPS), Sepsis severity score (SSS), Ranson score, Imrie score, Mannheim peritonitis index (MPI).
Mannheim peritonitis index (MPI) is one such prognostic system that helps us to estimate the probability of patient survival in cases of peritonitis.
