Abstract
ABSTRACT
Background
Acute appendicitis is the most frequent surgical emergency encountered worldwide.
This study was conducted to compare the efficacy of Tzanakis score and Alvarado
score in diagnosing acute appendicitis.
Objectives
The aim of this study is to compare the efficacy of Tzanakis scoring system with
Alvarado scoring system in diagnosing AA.
Methods
This was a retrospective and nonrandomized observational study conducted in
Dhulikhel hospital. It included 200 clinically diagnosed cases of acute appendicitis
who underwent emergency open or laparoscopic appendectomy during the year
2012. Final diagnosis of acute appendicitis was based on histological findings given
by pathologist.
Results
The sensitivity, specificity, positive predictive value and negative predictive value
of Tzanakis score was 86.9%, 75.0, 97.5% and 33.3% respectively. The sensitivity,
specificity, positive predictive value and negative predictive value of Alvarado score
was 76.0%, 75.0%, 97.2% and 21.4% respectively. Negative appendectomy was
8.0%.
Conclusion
Tzanakis scoring system is an effective scoring system in diagnosing acute
appendicitis.
