Background: Acute appendicitis is one of the most common surgical emergencies worldwide. Early and accurate diagnosis is crucial to avoid complications such as perforation and unnecessary surgeries. The Fenyo-Lindberg scoring system, a clinical decision tool developed using logistic regression, incorporates demographic, clinical, and laboratory parameters for objective diagnosis. This study aims to evaluate the diagnostic efficacy of the Fenyo-Lindberg scoring system in patients presenting with suspected acute appendicitis. 
Methods: This prospective observational study was conducted at Dr. RPGMC Kangra at Tanda over a one-year period and included 100 patients aged ≥12 years with clinical signs of acute appendicitis. Each patient was evaluated using the Fenyo-Lindberg scoring system. Surgical decisions were made independently of the score. Final diagnosis was confirmed via histopathology for operated cases and clinical resolution in conservatively managed cases. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall diagnostic accuracy were calculated using SPSS software. 
Results: The mean age of the study population was 28.7±11.2 years, with a male-to-female ratio of 1.27:1. At a cutoff score of ≥18, the Fenyo-Lindberg system demonstrated a sensitivity of 94.4%, specificity of 53.6%, PPV of 83.9%, NPV of 78.9%, and an overall diagnostic accuracy of 83%. Conclusion: The Fenyo-Lindberg scoring system is a sensitive and effective diagnostic tool for acute appendicitis, particularly useful in resource-limited settings. However, due to its moderate specificity, it should be used alongside clinical judgment and imaging when available.
