COMPARISON BETWEEN MODIFIED ALVARADO AND RIPASA SCORING SYSTEM IN DIAGNOSING ACUTE APPENDICITIS

Background: The most frequent emergency surgery is an emergency appendectomy, which is one of the most prevalent causes of acute abdominal pain. A clinical scoring system is the less expensive, quicker, and non-invasive diagnostic technique for identifying acute appendicitis. In order to aid in the diagnosis of an acute appendicitis and reduce unnecessary exploration, scoring systems based on the history, clinical examination, and essential investigations are available. Aim: The aim of the present study was to compare the Modied Alvarado scoring system (MASS) and the Raja Isteri Pengiran Anak Saleha Appendicitis score (RIPASA score) and to determine their diagnostic accuracy. Materials and Method: A prospective observational study was conducted in the Department of General Surgery, Sree Mookambika Institute of Medical Sciences, Kulasekharam for a period of one year. A total of 80 cases were included in the study. Alvarado and RIPASA scores were calculated. Diagnosis was conrmed on histopathological evaluation. Results were analysed using SPSS 20.0 version and the association was tested using Chi square test. The scores were compared based on sensitivity, specicity, Positive Predictive Value (PPV), Negative Predictive Value (NPV) and diagnostic accuracy. Results: Among the 80 patients, based on the Modied Alvarado score, 61(76.25%) patients and in RIPASA score 70(87.5%) patients clinically had appendicitis. On histopathological examination it was found that 70(87.5%) of the patients were diagnosed to have acute appendicitis. The sensitivity, specicity, PPV, NPV and diagnostic accuracy for RIPASA score were 98.57%, 90%, 98.57%, 90% and 69.11% respectively. This was higher than the sensitivity, specicity, PPV, NPV and diagnostic accuracy for Modied Alvarado score which was 82.86%, 70%, 95.08%, 36.84%, 58.08% respectively. Conclusion: When comparing the RIPASA score to the modied Alvarado score in diagnosing acute appendicitis, the RIPASA score was better. The Fourteen parameters have been made available in a thorough clinical history as well as evaluation and can be used quickly and readily. As a result, a management choice can be taken quickly. Thus, appendicitis-related mortality and morbidity can be decreased
