Abstract

 Introduction: Recent advances have included improved preoperative diagnostic studies, interventional radiologic procedures to drain established periappendiceal abscesses, and the use of laparoscopy to confirm the diagnosis and exclude other causes of abdominal pain. Laparoscopic appendectomy was first reported by the gynecologist Kurt Semm in 1982 but has only gained widespread acceptance in recent years. Methodology: Patients admitted in Victoria hospital, Bengaluru with features suggestive of Acute Appendicitis and undergoing surgery for the same were included in this study. For each patient Alvarado Score was calculated and the result of Ultrasonography was noted. Results: The sensitivity, specificity, positive predictive value and negative predictive value for Alvarado Scoring considering a score of >7 as positive in diagnosing acute appendicitis are 52.08%, 100%, 100%,8% respectively. The diagnostic accuracy is 54%. Conclusion: No statistical difference could be proven between Alvarado scoring and Ultrasonography in diagnosing Acute Appendicitis.

Keywords: Appendicitis; Alvarado Score; Ultrasonography.
