Effectiveness of mannheim peritonitis index in predicting the morbidity and mortality of patients with hollow viscous perforation

BACKGROUND: Peritonitis due to hollow viscous perforation is common cause of emergency surgery in India. Despite advances in surgical skills, antimicrobial agents and supportive care the morbidity and mortality of secondary peritonitis remains high. Prognosis and outcome of it depends on many factors which includes patient related factors, disease specific factors and management. Categorizing patients into different risk groups would help in management. Mannheim peritonitis index (MPI) is based on measuring simple clinical parameters in case of hollow viscous perforation. This study was conducted to know efficacy of MPI for predicting morbidity and mortality in hollow viscous perforation. AIMS AND OBJECTIVES: This study attempts to evaluate the prognostic value of Mannheim Peritonitis Index MPI scoring system in patients with peritonitis due to hollow viscous perforation, to assess it as a clinical tool in stratifying these patients according to individual surgical risk. METHODS: 64 patients with peritonitis undergoing surgical treatment at Govt. Kilpauk Medical College, Chennai were included in study. Demographic, clinical data, surgical treatment, outcome were documented and analysed. RESULTS: The morbidity and mortality rate were higher in patients with MPI >29. Surgical site infections were most common complication in patients with MPI>29. More ICU stay was required in patients with MPI>29 and mortality also higher in patients with MPI>29. CONCLUSION: MPI which is very easy to calculate is simple and effective in predicting morbidity and mortality in patients with hollow viscous perforation
