Evaluation of Right Iliac Fossa Pain with Reference to Alvarado Score – Can We Prevent Unnecessary Appendicectomies?

摘要

Background: Appendicectomy for acute appen-dicitis is the most common surgical cause ofemergency laparotomy throughout the world.Acute appendicitis is a clinical diagnosis; theaccuracy of clinical examination has been re-ported from 71 to 97% and varies greatly de-pending upon the experience of the examiner.The treatment being surgical, negative appen-dicectomy rates are high. Aim and Objective:Present study was conducted to evaluateAlvarado Scoring system for diagnosis of acuteappendicitis and its co-relation by histopathol-ogy. Material and Methods: Prospective studyof consecutive patients admitted with suspectedacute appendicitis during the period of July2011 to December 2012 was undertaken.Alvarado Score of each patient was calculated.Out of 130, 95 patients had histologicallyproven acute appendicitis. Reliability of scor-ing system was assessed by calculating posi-tive predictive value and negative appendicec-tomy rate. Results and Conclusion: The posi-tive predictive value was 88.37% and negativeappendicectomy rate was 11.63% (with respectto Alvarado score 7). Alvarado Scoring sys-tem is easy, simple, cheap, useful tool in pre-operative diagnosis of acute appendicitis.
