The pre-operative risk of surgical site infection after liver resection
This model calculates the preoperative probability of developping a surgical site infection (SSI) after liver resection. SSI may either be an incisional infection or an intra-abdominal infection. Additional measures may be taken in patients with increased risk.

The model was created in a Dutch multicenter cohort study, and is based on logistic regression. The study included 982 liver resections, both benign and malignant indications.

Conditional information

Precautionary measures in high risk patients might include an extended antimicrobial prophylaxis, for instance based on rectal cultures that may be obtained preoperatively to detect colonization of resistant microbes and adjust antibiotic prophylaxis. Furthermore, a more extensive antiseptic regime for instance with chlorhexidine body wash preoperatively, the use of antimicrobial coated sutures, and the use of wound protectors or negative pressure wound therapy. Finally, enhanced nutritional support, and physical prehabilitation to optimize the immuno-nutritional status, might reduce the risk of SSI. See also the WHO Global guidelines on the prevention of surgical site infection.
