Correlation between Alvarado score and preoperative serum hyperbilirubinemia as a new diagnostic modality for severity of acute appendicitis

Introduction: Acute appendicitis is a prevalent abdominal emergency that necessitates immediate surgery. The mostcommon emergency procedure carried out globally is an appendectomy.Objective: To assess the clinical significance of the preoperative correlation between the Alvarado score and serumhyperbilirubinemia and to evaluate their ability to predict the severity of acute appendicitis clinically.Patients and Methods: This cross-sectional analytic study was performed at the Department of General SurgeryEmergency of a tertiary hospital in the period between June 2022 and March 2023. This study was carried out on 208cases with acute appendicitis.Results: The mean age of participants was 29.17±14.452 years, predominantly males (54.8%). About two-thirds ofthe cases (67.8%) underwent open appendectomy, 58 (27.9%) underwent laparoscopic appendectomy, and nine (4.3%)underwent laparoscopic and then converted to open appendectomy. More than half of the cases were categorized asprobably appendicitis by Alvarado score. There was a statistically significant difference comparing Alvarado’s scores andthe pathological findings of the participants (P=0.021). No statistically significant differences were recorded betweenAlvarado score findings and preoperative serum bilirubin levels.Conclusion: The study found an association between Alvarado’s score and pathology findings. However, no statisticallysignificant differences were recorded between the Alvarado score and preoperative serum bilirubin levels.
