ABSTRACT
Objective: To assess the sensitivity of the Alvarado score [AS], modified Alvarado score [MAS], Fenyo-Lindberg score [FS], Lintula score [LS], Eskelinen score [ES], Teicher score [TS], and Christian score [CS] [seven scorings] in patients with acute appendicitis [AA]
Study Design: Analytical study
Place and Duration of Study: The First Affiliated Hospital of Chongqing Medical University, China, from January 2012 to June 2015
Methodology: Patients with diagnosis of AA were evaluated retrospectively to compare the scoring systems. The diagnostic sensitivity [the correct number of diagnoses divided by the total number] was compared. Data were analyzed using SPSS software
Results: One hundred and seventy-nine patients were studied. The sensitivity of AS was 92.7%; It outperformed each of the other scores. The sensitivity of FS, LS, and TS in women was lower than that in men [p=0.016, p<0.001, and p<0.001, respectively]. The sensitivity of the FS, ES, TS, and CS in patients with a duration of illness greater than 48 hours was lower than that in patients with a duration of illness less than 48 hours [p<0.001 for all]
Conclusion: AS is the most useful and sensitive diagnostic tool for AA. FS, LS, and TS had a lower diagnostic sensitivity in women; and FS, ES, TS, and CS had a low sensitivity in patients with a duration of illness greater than 48 hours
