“…1 Clinical examination is helpful in diagnosis of acute appendicitis in only 70 to 87% of the cases. 4 About 20% to 33% of patients with suspected acute appendicitis have atypical findings making clinical diagnosis difficult which requires plasma markers and imaging techniques. 5,6 Due to this overlap of symptoms, the rate of negative appendectomy has been reported to range from 20% to 40%.…”

Introduction: Acute appendicitis is the most common pathology encountered among the patients with acute abdominal pain. Nowadays, different scoring systems are used to diagnose acute appendicitis. One of them is Tzanakis scoring, which is a combination of clinical examination, ultrasonography, and laboratory markers of inflammatory markers. Hence, this study was done to assess the diagnostic accuracy of Tzanakis scoring system in diagnosing acute appendicitis and compare its accuracy with histopathological examination. Methods: A retrospective observational study of all cases of acute appendicitis was conducted from July 2018 to June 2019 at the Department of Surgery, Western Regional Hospital.Out of 403 patients who had undergone appendicectomy during the period of one year, the necessary documents of 83 patients could not be collected. Hence, 320 patients were included in our study. The ethical approval was taken from the Institutional Review Committee (Ref. No. 14. 2077/078). Total Tzanakis score of all patients who underwent appendicectomy during this period was calculated and compared with histopathology report. Sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy were calculated. Results: The sensitivity,specificity of Tzanakis score of all 320 patients who underwent appendicectomy was 84% and 71% respectively. The diagnostic accuracy was 84% with positive predictive value 98% and negative predictive value 17%. Conclusions: The Tzanakis scoring system is simple, effective and easy to be applicable for the diagnosis of acute appendicitis.

“…By the application of this reliable Ultrasound-based score for diagnosing acute appendicitis, the process of decision making has improved, especially in developing countries lagging in resources. 6,7 In a recent study done in Pakistan, its sensitivity, specificity and overall diagnostic score was determined to be 99%, 91% and 95% respectively 8 indicating that it to be an accurate modality for - ----------------------------------------------------------------------------------------Received on 15-06-2021 Accepted on 25-10-2021 diagnosing of acute appendicitis and preventing a negative laparotomy in this region of the world. 9 However, a prospective study done in 2019 in India concluded that Tzanaki score is considering better diagnostic scoring system than Alvarado score for acute appendicitis 10 .…”

Aim: To find out how accurate the Alvarado and Tzanaki scoring systems are in diagnosing acute appendicitis taking histopathology as gold standard. Methods: A cross-sectional prospective study was conducted from August 2019 to July 2020 at Department of General Surgery, Pakistan Institute of Medical Sciences Islamabad. Sixty patients were included, all of whom had appendectomies after a clinical diagnosis of acute appendicitis. Samples were submitted for histopathology, which was used as the gold standard for the definitive diagnosis of acute appendicitis. The specificity, sensitivity, positive predictive value (PPV), negative predictive value (NPV), diagnostic accuracy and negative appendectomy rate of Alvarado and Tzanaki scoring systems was calculated using SPSS version 23. Results: The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of Alvarado score at optimal cut-off threshold of ≥7.0, were calculated as 74%, 55%, 90%, 27% and 71.66% respectively. The cut-off threshold point of Tzanaki score was set at more than 8, which yielded a 94.11% sensitivity and an 88.88% specificity. The positive predictive value was 99.95% and the negative predictive value was 72.72%. The Alvarado and Tzanaki scoring systems had negative appendectomy rates of 9.5% and 2.04%, respectively. Conclusion: The Tzanaki scoring system has a better diagnostic accuracy for acute appendicitis as compared to the Alvarado score. Keywords: Acute appendicitis, Alvarado score, Tzanaki score
