Evaluation of Modified Alvarado Score Combined With Ultrasonography in Decreasing Negative Appendicectomy Rate

Background And Objectives – to assess accuracy of modified Alvarado score along with aid of ultrasonography in the pre-operative diagnosis of acute appendicitis to decrease the negative appendicectomy rate. Methods-A consecutive series of 100 patients who came to emergency opd with provisional dia gnosis of acute appendicitis was evaluated with modified Alvarado score and subjected to ultrasonography ,diagnosis was confirmed by histopathology. Resultsin our study men were affected more than women 1.2:1, 4 men with Alvarado score <7 had negative appendectomy (7.2%), and two women with scores >7 and 4 women with scores <7 had negative appendectomy(13.3%). Conclusionscombined technique of using both clinical and sonological criteria is a cheap and effective tool in diagnosing appendicitis and reduce the negative appendectomy.
