Methods: Patients undergoing appendectomy January 2012- December 2014 were included in prospective study. We collected and analyzed data on patient demographics; length of symptoms; times of presentation, admission and surgery; antibiotic administration; operative findings; and occurrence of SSI. Comparison of data between two groups was undertaken with chi-square tests for categorical data and student’s t-test or Mann-whitney test for continuous data. The p value of less than 0.05 was considered statistically significant.
Results: In 400 patients (234 female (58.5%) and 166 male (41.5%)) who underwent appendectomies the average age was 41.48 year old. Ruptured appendicitis was found in 106 patients (26.5%). Group I included patients who underwent appendectomy within 12 hours of diagnosis and group II included those appendectomies performed greater than 12 hours after diagnosis. . The operative time (50.14 vs 57.7 minutes), length of stay (2.65 vs 2.09 days), wound infections (4 vs 6), and antibiotic use at discharge (19 vs 3) for group I and II were not statistically different.
Conclusion: In-hospital delay more than 12 hours was not associated with significantly higher risk of SSI in patients who underwent appendectomies.
