Diabetic foot wound ulcers management by vacuum sealing drainage: A meta-analysis

The meta-analysis aimed to assess and compare diabetic foot wound ulcer management by vacuum sealing drainage. Using dichotomous or contentious random- or fixed-effects models, the outcomes of this meta-analysis were examined, and the odds ratio (OR) and the mean difference (MD) with 95% confidence intervals (CIs) were computed. Twenty-three examinations from 2000 to 2023 were enrolled for the present meta-analysis, including 1928 individuals with diabetic foot ulcers. Vacuum sealing drainage had significantly lower wound healing (OR, 2.35; 95% CI, 1.79-3.08, p < 0.001), lower duration of therapy (MD, -6.19; 95% CI, -10.06 to -2.32, p = 0.002), higher wound size reduction (MD, 4.22; 95% CI, 0.87-7.56, p = 0.01) and lower complication (OR, 0.32; 95% CI, 0.13-0.80, p = 0.01) compared with standard therapy in patients with diabetic foot ulcers. The examined data revealed that vacuum sealing drainage had significantly lower wound healing, duration of therapy and complication rates, as well as higher wound size reduction, compared with standard therapy in patients with diabetic foot ulcers. Yet, attention should be paid to its values since most of the selected examinations had a low sample size.
