Abstract

BACKGROUND: The most common complication of a surgical operation is surgical site infection (SSI). SSI is associated with an increased length of stay and healthcare cost. Appendectomy is the most common surgical operation and infections at the site of the surgery are the most frequently observed complications following an appendectomy. Although antibiotic prophylaxis would be used, the wound infection at the surgical incision could increase morbidity in the patients.


OBJECTIVE: This study sought to assess the risk factors associated with postoperative infections at the site of the surgery after an appendectomy in pediatric patients at Vajira Hospital, Bangkok, Thailand over a five-year period.


METHODS: A retrospective study of appendectomy patients aged from 0 to 15 years whose appendicitis treatment was performed from January 2017 to December 2021, at Vajira Hospital. The demographic data of the patients, diagnosis, operative findings, and disease-related factors were analyzed.


RESULTS: The sample comprised 335 pediatric patients. Fifteen patients (4.4%) developed an SSI. In the univariable analysis, the longer operative time >60 minutes and the BMI for age of a 95th percentile or greater was associated with SSI. After binary logistic regression analysis, the BMI for age of the 95th percentile or higher showed a significant risk of infection at the site of surgery (OR 4.58; 95%CI 1.13-18.54).


CONCLUSIONS: BMI for age of the 95th percentile or greater (obesity) was the risk factor for SSI after an appendectomy in pediatric patients.
