[Systematic investigation of surgical site infections (SSI) in plastic reconstructive and aesthetic surgery (ERCS): Feedback]. / Investigation systématique des infections de site opératoire (ISO) en chirurgie plastique reconstructrice et esthétique (CPRE) : retour d'expérience.

Surgical site infection (SSI) in plastic, reconstructive and aesthetic surgery (ERCP) is quite uncommon compared to other surgical specialities but remains one of the main complications. The aim of our study was to provide feedback on the systematic investigation of SSI in ERCP. This is a monocentric retrospective study, including all paediatric and adult patients who have undergone ERCP surgery between 01/01/2014 and 31/12/2021. During this period, the department systematically investigated all SSI cases. Eight thousand eight hundred and seventy-eight surgical procedures were performed. The SSI rate was 0.34%. Thirty SSIs (19W,11M), with a mean age of 56 years (none paediatric), were investigated. Twenty-seven patients suffered from comorbidities. The surgical indications included 17 cases of skin cancer, 7 cases of weight loss, 4 cases of breast reconstruction, 1 lipoma, 1 pectus excavatum. Eleven surgeries consisted in lymphnode procedures (8 sentinel lymphnodes, 3 curage). The average operating time was 116minutes. Nineteen patients received antibiotic prophylaxis. The average time to onset of SSI after surgery was 10 days. The most prevalent bacteria were commensals of the skin flora and the digestive tract. Apart from surgical management, 100% of patients were treated with antibiotics. High age, multiple comorbidities, long, combined procedures, placement of equipment, lymph node surgery, post-operative punctures on implanted equipment, are all risks factors for SSI. The implementation of a systematic monitoring of SSI within our department has provided us with the opportunity to analyse our data in real time and allow us to adjust our practices if necessary. This process can be used in other plastic reconstructive and aesthetic surgery departments. The collection and analysis of SSIs is both easily done and the procedure is well standardized. The assistance of the operational hygiene team is a key asset for the success of this project. The development of this type of procedure on a national level could be an asset to improve the management of SSI by taking advantage of the experience of a larger number of centres.
