Recently negative pressure wound therapy (NPWT) is increasingly being prophylactically used to prevent wound complications in various types of surgeries, but its role in spinal fusion surgery was less well established. This study aimed to evaluate the efficacy of prophylactic NPWT (PNPWT) usage in spinal fusion surgery.
Following PRISMA guidelines, databases PubMed, Embase and Web of Science were searched for relevant studies. Studies comparing PNPWT with standard wound dressing (SWD) were included and analyzed. The primary outcome was the incidence of surgical site infection, and secondary outcomes were incidence of wound dehiscence, overall wound complication, readmission and reoperation.
A total of five studies were included; there were 279 patients in PNPWT group and 715 patients in SWD group. Four studies investigated surgical site infection; the pooled analysis showed a significantly lower incidence of surgical site infection in PNPWT group (OR: 0.399; 95% CI: 0.198, 0.802). Two studies explored wound dehiscence, three studies reported overall wound complication, and there were no significant differences between the two groups ((OR: 0.448; 95% CI: 0.144, 1.389) and (OR: 0.562; 95% CI: 0.296, 1.065), respectively). Two studies evaluated readmission, three studies compared reoperation rate, and the pooled results demonstrated no significant difference between the two groups ((OR: 1.045; 95% CI: 0.536, 2.038) and (OR: 0.979; 95% CI: 0.442, 2.169), respectively).
The current evidence suggested PNPWT could effectively reduce postoperative surgical site infection, but it had no significant benefit on reducing the incidence of wound dehiscence, overall wound complication, readmission and reoperation.
