Abstract:
Our prospective observational study, enrolling 167 patients undergoing emergency appendicectomy, served to evaluate the Alvarado, Tzanakis and RIPASA diagnostic scores. The latter was found to be a better scoring system because of its higher diagnostic accuracy. At centres with limited expertise in ultrasonography, RIPASA outperforms the Tzanakis score. Although easy to use, the Alvarado score was useful only to 'rule in' cases with AA with significant accuracy but at the cost of low sensitivity. It cannot be effectively used in triaging.
