Mannheim's Peritonitis Index Validation Study in the Indian Set-Up

The Mannheim peritonitis index emerged as a reliable marker for assessing the severity and prognosis of Intra-abdominal infection. This is a randomised prospective study including 50 cases in our institute having clinical suspicion of peritonitis. Outcome of peritonitis was predicted by Mannheim peritonitis index. Postoperative follow up was done clinically for 30 days. Mortality rate is more with high MPI score. In our study, MPI score is divided in to two or three interval. With high number of MPI score patient has bad prognosis. With age more than 50 year, late presentation, diffuse peritonitis, purulent exudate, non-colonic pathology and organic failure associated with high MPI score and more mortality. The favourable prognostic factor are age less than or equal to 50 year, early presentation, colonic pathology, localized peritonitis, non-purulent exudate without organ failure. MPI is simple useful method to determine the outcome of patient with peritonitis with sensitivity and specificity comparable to APACHE II score which has been adopted as the gold standard by Surgical Infection Society.
