Background.Acute appendicitis is defined as the inflammation of the appendix
vermiformis. Given the prevalence of the diagnosis within the Indonesian territory, it
is relevant to compare the accuracy of the tests pertinent to the disorder. Currently,
there are two methods to diagnose it: based on signs and symptoms, called the
Alvarado Scoring System; or based on signs, symptoms, together with ultrasound
results, called the Tzanakis Scoring System
Goal. To compare the sensitivity and specificity between Alvarado and Tzanakis
Scoring System in the diagnosis of Acute Appendicitis.
Method. The comparative study is conducted retrospectively using the medical
records of Atma Jaya Hospital of reported cases of acute appendicitis within the
period of January 2013-June 2014.
Results. The sensitivity and specificity of the Alvarado scoring system is 77.78% and
28.57% respectively; whereas for the Tzanakis Scoring System, it is 91.67% and
28.57% respectively.
Conclusion. The Tzanakis scoring system has a higher sensitivity compared with the
Alvarado scoring system in accurately diagnosing patients with acute appendicitis.
However, for a specificity, both have equal values.
Suggestion.Prospective study techniques together with improved accuracy and
comprehensiveness of medical records are necessary for this research. |
