Background: If properly used in appendicitis, antibiotics can reduce the rate of infection by 50%. The use of post-operative antibiotics for preventing infective complications in non-perforated cases is still controversial.

Methods: A randomised prospective study was conducted in the Department of Surgery, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi with patients who presented acute appendicitis. A minimum number of 30 patients each in group A (pre-operative and post-operative antibiotics) and group B (only pre-operative antibiotics) were evaluated for 18 months, from January 2018 to June 2019.

Results: The mean age of group A is 29.9±15.16 years and in group B is 25.97±9.470 years (p value=0.122, insignificant). There was male preponderance. The seroma formation in both the groups was 10.00% and no patients developed intra-abdominal abscess. The incidence of local site oedema was 10% in both the groups A and B and their p value is insignificant. In both the groups A and B, 10% of the people developed pus discharge from the stitch line and the p value is insignificant. In group A, 6.67% of the patients and in group B 10.00% of the patients developed stitch line inflammatory changes and the p value insignificant. In group A, 13.3% and in group B, 10.00% of the patients developed fever and their p value is 1. The mean length of hospital in case 1.23±0.5 days (group A) and is 1.17±0.45 days (group B) (p value=0.508).

Conclusions: Hence we can conclude that a well-chosen and adequately-timed pre-operative antibiotics are adequate in preventing post-operative complications and post-operative antibiotics do not affect the same.
