Abstract: Appendicitis is inflammation of the appendix. Symptoms commonly include right lower abdominal pain, nausea, vomiting, and decreased appetite. However, approximately 40% of people do not have these typical symptoms. Severe complications of a ruptured appendix include widespread, painful inflammation of the inner lining of the abdominal wall and sepsis . Most of the appendicitis patients were in the age group of 31-40 years followed by 41-50 year age group. In the present study 60% of the cases were male and 40% cases were belongs to female gender. Of the 50 patients, 16 patients had score below 7 in which 12 patients had score between 5-7 and 4 patients had score between 1-4. USG showed 50% sensitivity, 50% specificity, 75% positive predictive value, 25% negative predictive value and 50% accuracy in Alvarado score of 1-4. In the score range of 5-7, USG showed 95.24% sensitivity, 100% specificity, 100% positive predictive value, 50% negative predictive value and 95.45% accuracy. In the score of more than 7, USG showed 67.80% sensitivity, 100% specificity, 100% positive predictive value, 66.67% negative predictive value and 68.33% accuracy.
