A systematic literature search was performed according to the PRISMA guidelines. All human studies describing patients treated with SSd were included, when at least of evidence level consecutive case series. Studies describing up to 20 patients were pooled to improve readability and prevent overemphasis of findings from single small studies.
Ten studies, one cohort study and nine case series, all classified as poor based on Chambers criteria for case series, were included. Compared to patients treated with EBd, patients treated with SSd had no increased mortality rate, LOS or complication rate. SSd-treated patients had a high rate (75%) of total delayed primary closure (DPC) in the pooled case series.
The current available evidence is of insufficient quality to conclude whether SSd is noninferior to EBd for all assessed outcomes. There are suggestions that SSd may result in a decreased need for skin transplants, which could potentially improve the (health related) quality of life in survivors. Experienced surgical teams could cautiously implement SSd under close monitoring, ideally with uniform outcome registry.
