Background: One of the earliest scoring systems for projecting surgical outcome was POSSUM. In general surgery, it was discovered that the P-POSSUM approach was more reliable for predicting death. Objectives - The chief objectives of present research are to examine the validity and assessment of the PF Portsmouth Possum Scoring in cases of exploratory laparotomy and to study the mortality rates using Portsmouth POSSUM scoring in patients undergoing laparotomy and to calculate observed/predicted ratio for mortality based on Portsmouth POSSUM. Materials and Methods: An observational clinical trial that was to be done in general surgery and SICU wards at the Department of General Surgery, MGM Medical College and Hospital, Aurangabad was prospective and non-randomized. The patients on admission were evaluated as per Portsmouth - Possum Scoring. Operative outcomes had been taken note off, and a tailored surgical procedure would be performed. The patients were then assessed and the data will then be analyzed using the linear technique of analysis. After that, the observed to anticipated (O:P) ratio will be determined. Result: Using a linear analytic equation, the observed and P-POSSUM predicted death rates were compared. The obtained observed to expected ratio (O: E) was 1.5 (p=0.429), which was not statistically significant. Conclusion - P-POSSUM score includes the identification of high risk patients who would benefit from expedited surgical treatments or improved resuscitation during the pre and intra-operative phases.
