ABSTRACT

Background: Acute appendicitis represents the most common cause of acute abdomen surgery. However, patients with negative appendicitis might undergo unnecessary appendectomy which isconsidered problem in clinical practice. Objective: The aim of this study was to compare performance of RIPSA and Alvarado score in diagnosis of appendicitis. Patients and Methods: A comparative analytic study conducted for the period fifteen month (September 2021- December 2022) at Tishreen University Hospital in Lattakia-Syria. The study included patients who diagnosed with acute appendicitis and underwent surgery. Results: A total of 232 patients with mean age 26.31±10.7 of years were included in the study. Age group <40 years represented the most age group(87.9%) and 53.9% of the patients were males. The most common presenting symptom was pain in right iliac fossa (100%), while tenderness in right iliac fossa was the most common sign(98.7%). Abdominal ultrasound was positive in 58.19% of the study population, while CT-scan was positive in all cases which was performed(7 cases). RIPSA score was positive in 91.8% of the cases and Alvarado score was positive in 81.5%. RIPSA score exhibited sensitivity(98.13%) and specificity(88.23%) in diagnosis appendicitis, whereas Alvarado score had a sensitivity and specificity of 95.81% and 82.35% respectively. After age-and sex adjustment, RIPSA score was superior to Alvarado score in detecting presence of acute appendicitis. Conclusion: The current study results indicated that RIPSA score has higher diagnostic accuracy in distinguishing patients with acute appendicitis compared to Alvarado score.
