Ann King Edward Med Uni Jan ;10(1):52-4.

Objective: To compare the accuracy of clinical diagnosis of Acute Appendicitis with that of Alvarado Score System in Children. Design: A Prospective and Comparative Study. Patients and Duration of Study: Department of Pediatric Surgery, Nishtar Medical College & Hospital, Multan from January 200I to June 2002. All patients of pain abdomen with suspicion of acute appendicitis were included in study. Subjects and methods: 92 patients were admitted with pain abdomen, After preliminary history and examination sixty were suspected of acute appendicitis. A Detailed history, clinical examination and relevant investigations were done. These patients were divided in two equal groups of 30 each. In group-I all the findings were entered on Performa based on the indicants of modified Alvarado Score. Later on their Score was calculated according to the assigned weight-age of each indicant. Twenty-eight patients were submitted for Surgery having Alvarado Score of >7. In group-II patients were clinically evaluated by one of the consultant to declare the diagnosis of Acute Appendicitis or otherwise. Twenty-nine out of 30 were submitted for surgery in this group. Three cases turned out to be of mesenteric lymphadenitis confirmed on Ultrasonography. The diagnosis of Acute Appendicitis was further confirmed by Histopathology of appendix after removal. Hence the accuracy of both methods was compared. Results: The diagnostic accuracy of Alvarado Score was 85.71% with false positive or negative appendectomy rate of 14.29% while the accuracy of clinical diagnosis was 93.01% with false positive or negative appendectomy rate of 6.99%.
