A prospective study to evaluate the utility of Mannheim peritonitis index in predicting prognosis of perforation peritonitis at our tertiary care centre

Background: This study was aimed to evaluate the validity of Mannheim Peritonitis Index (MPI) in predicting the outcome in patients with perforation peritonitis.Methods: A prospective study was designed for a study period of 2 years, 75 patients who underwent operation for perforation peritonitis were included in the study. Post evaluation done with predesigned proforma, MPI score was calculated and analyzed for each patient who underwent surgery, death being the main outcome measure. The MPI scores were divided into three categories. MPI scores <15 (category 1), 16-25 (category 2), and >25 (category 3).Results: Present study consisted of 60 males and 15 females (male:female ratio of 4:1) with the mean patients age 37.96±17.49 years. 47, 26, and 27 cases belonged to MPI score categories 1, 2, and 3. The dominating source of perforation was small intestinal. The individual parameters of MPI score were assessed against the mortality, age >50 years (P = 0.015), organ failure (P = 0.0001), noncolonic origin of sepsis (P = 0.002), and generalized peritonitis (P = 0.0001) were the factors significantly associated with mortality. The sensitivity of MPI was 92% and specificity was 78% in receiver operating characteristic curves.Conclusions: MPI is an effective tool for prediction of mortality in cases of perforation peritonitis.

Background: Peritonitis is defined as inflammation of the peritoneal cavity, caused by a number of etiologic agents including bacteria, fungi, viruses, chemical irritants, and foreign bodies. The Mannheim peritonitis index (MPI) is one of the simple scoring systems in use that allows the surgeon to easily determine outcome risk. Aims and objective: To estimate outcome of patients with perforation peritonitis. To evaluate effect of MPI score in identification of high risk cases.Methods: A prospective study was conducted in 100 patients with peritonitis due to hollow viscous perforation at surgical unit of tertiary care unit. The duration of study was 2 years. All the data was recorded. Written informed consent was obtained and data was analyzed using appropriate analysis strategy.Results: In this study, total 100 patients enrolled, out of which 54 % patients were in the age group <50 years and 46% patients were in the age group >50 years. Mortality was higher among patients with age group more than 50 years (21%) and in female patients (37.93%). 18 patients had organ failure. 87 patients had preoperative duration was >24 hours. 93% patients had non-colonic origin of sepsis. In 52 (52%) patients total MPI score was <21 while 25 (25%) patients total score was 21-29 and it was >29 in 23 (23%) patients. Mortality was higher among patients with MPI Score more than 29 (95.65%).Conclusions: MPI is accurate to be used with patients with peritonitis and should be considered reliable and simple reference for estimating their risk of death. This study differs in one adverse outcome variables, non-colonic origin of sepsis, we advocate need for further studies on Mannheim peritonitis index to include colonic origin of sepsis.
