Skin excisions are common procedures in children. They may be performed in the clinic using field sterility or the operating room with strict sterile technique. We compared the effect of these locations and the use of antibiotics on the incidence of surgical site infection (SSI) after skin excisions. Patients ages 0-18 years presenting to our department for the excision of lesions from 2006 to 2010 with complete medical records were included in our study. Records were reviewed for demographic characteristics, presentation, perioperative conditions, and postoperative SSI and other wound complications. Analyses were performed to estimate the costs associated with sterility technique and perioperative antibiotic use. We identified 700 patients with a mean age of 9.1 years. Of 872 lesions excised, 0.3% resulted in SSI and 1.8% had other wound complications. The incidence of SSI did not vary according to sterility technique, antibiotic usage, surgeon, age, or lesion size, type, or location. The equipment costs to excise a lesion in the operating room were 200% greater than in the clinic. The incidence of SSI after excision of benign lesions in children did not differ between those performed using clinic field sterility and those using the standard aseptic sterile technique in the operating room. A considerable cost savings could be realized by adopting field sterility for simple excisions performed in the operating room and avoiding routine perioperative antibiotics in pediatric skin excisions.
