TO STUDY PROGNOSTIC FACTORS IN PERFORATION PERITONITIS AND EVALUATING THE OUTCOME OF PATIENTS WITH PERFORATION PERITONITIS USING MANNHEIM PERITONITIS INDEX

BACKGROUND: Perforation peritonitis constitutes one of the commonest surgical emergency operation encounteredby surgeons all over world as well as in India.There is no single,easily available laboratory test that predicts severity orprognosis in patients with perforation peritonitis. The aim of this study is to study prognostic factors in perforationperitonitis and evaluating the outcome of patients with perforation peritonitis using Mannhein Peritonitis Index.MATERIALS AND METHOD:The study was a prospective analytical study done in the Department of General Surgery,JNIMS,Imphal from 1st September 2017 to 31st august 2019 comprising of 100 consecutive patients in which diagnosis ofperforation peritonitis were established by operative findings or surgical interventions during management wereincluded in the study as per the inclusion and exclusion criteria.RESULTS: Among the various prognostic factors of the scoring system, age >50 years, nature of peritoneal fluidexudates and presence of organ failure had a significant role in predicting the eventual outcome of the patients.Colonicorigin of sepsis was associated with worse outcome probably due to presence of faecal exudates which is commonlyassociated with colonic origin of sepsis. MPI < 21 was associated wih complications in 25% of patients whereascomplications increases as MPI score increases with 34.5% of patients having complication in MPI ranging from 21-29.CONCLUSION: MPI is disease specific, easy scoring system for predicting outcomes in patients with perforationperitonitis
