Patients with score of 7 or more of modified Alvarado score were included, patients with score of 6 or less were excluded. All patients underwent diagnostic laparoscopy, and the diagnosis was confirmed by histopathological examination. RESULTS: There was total of 228 patients. Twenty -four percent were overweight and 12% patients were obese. Sixty percent of the patients had confirmed diagnosis of acute appendicitis. CONCLUSION: Modified Alvarado scoring system is an easy method for diagnosis for acute appendicitis. It can be used as complementary aid for supporting the diagnosis of acute appendicitis in overweight and obese patients.
