Background and Aim: This study set out to determine whether or not the use of Alvarado scoring and Ultrasonography together improved the accuracy of diagnosing acute appendicitis and whether or not it decreased the number of false-positive appendicectomy outcomes without increasing their associated morbidity and mortality. Study design: Cross-sectional study, conducted in the Department of Surgery at Government Medical College Haldwani Nainital. Patients and Methods: The participants were recruited from an emergency department or surgical ward and presented with symptoms suggestive of acute appendicitis, including abdominal pain, rebound tenderness, nausea, vomiting, or elevated temperature. Results: The study found that those between the ages of 21 and 40 had the highest rate of developing acute appendicitis. Evidently, the incidence is highest in the second, third, and fourth decades of life, Males outweigh females by a factor of two to one in this series, on correlating the Alvarado score to appendix histopathology data, and discovered that it had a sensitivity of 96.39 percent. On the correlation between ultrasonography and histopathological examination showed a sensitivity of 100% and a PPV of 86.46 percent. Conclusion: Combined use of the Alvarado score and USG in appendectomy decision-making has high sensitivity and accuracy, allowing patients to be diagnosed in the early acute appendicitis stage, and reducing morbidity and postoperative complications.
