There was no difference in the effect of wound protectors based on the target organ for surgery, even with a high number of patients in one of the appendectomy trials, which the authors were concerned may have skewed the results.
Overall, the authors rated the evidence to be of moderate quality, but several studies had a high risk of bias.
The authors said that one barrier to routine use of these devices was cost. However, given that surgical site infections are estimated to cost around $3.5 billion to $10 billion annually in health care expenditures, they argued that “the use of dual-ring wound edge protectors should be considered in open lower gastrointestinal surgery, including open appendectomies.”
No funding sources or conflicts of interest were declared.
