Evaluation of Mannheim Peritonitis Index (MPI) Scoring System in Prognosis of Patients with Peritonitis Due to Hollow Viscus Perforation at Tezpur Medical College and Hospital

Background: Peritonitis due to hollow viscus perforation is a severe surgical emergency associated with high morbidity and mortality. The Mannheim Peritonitis Index (MPI) has been proposed as a prognostic tool to assess disease severity and guide management decisions in such cases. Methods: A retrospective cohort study was conducted at Tezpur Medical College and Hospital, involving 203 patients diagnosed with peritonitis secondary to hollow viscus perforation. Data on demographics, clinical presentation, MPI scores, and clinical outcomes (mortality, length of hospital stay) were collected and analyzed. MPI scores were categorized into low-risk (≤ 20), moderate-risk (21-29), and high-risk (≥ 30) groups. Results: Higher MPI scores were associated with increased mortality rates and prolonged hospital stays. Mortality rates were 12.1% in the low-risk group, 28.9% in the moderate-risk group, and 54.2% in the high-risk group. Mean hospital stays increased from 8.5 days in the low-risk group to 16.3 days in the high-risk group. These findings highlight the MPI’s effectiveness in stratifying patients and predicting outcomes in peritonitis due to hollow viscus perforation. Conclusion: The MPI serves as a valuable prognostic tool in peritonitis, aiding clinicians in risk stratification and guiding therapeutic interventions. Early identification of high-risk patients using the MPI facilitates timely management, potentially improving patient outcomes in this critical surgical condition.
