To Evaluate the Utility of RIPASA Scoring System in the Diagnosis of Acute Appendicitis and to Correlate Histopathological Finding with this Scoring System

Patients with palpable appendicular lump, appendicular abscess, previous history of urolithiasis and pelvic inflammatory disease were excluded from the study. The myriads of scoring system have been devised based on clinical history, physical examination and laboratory finding which help in early diagnosis and prompt management of acute appendicitis (e.g, Alvarado, Fenyo, Techer, Ramirez , Christian scores).The two promising scoring systems with increasing sensitivity and specificity in diagnosing acute appendicitis and to reduce the negative appendectomy rates are modified Alvarado and RIPASA score. The negative appendectomy rate decreased significantly from 16.3% to 6.9%, which was 9.4% reduction [3].Since not many studies have been conducted on RIPASA scoring system in the diagnosis of acute appendicitis, we have prospectively studied RIPASA score by applying them to the patients attending our tertiary care hospital with right iliac fossa pain. In our study, the sensitivity of RIPASA Scoring system was 92.47%, specificity 86.92%, positive predictive value 86% and negative predictive value of 93%.
