RÉSUMÉ
PURPOSE: We analyzed the usefulness of vacuum-assisted closure (VAC) dressing to facilitate the healing of difficult wounds by comparing the results of conventional dressings. MATERIALS AND METHODS: We selected 20 cases for the experimental group (VAC group) and 20 cases for the control group (conventional dressing), and investigated the change in wound size, formation of granulation tissue, and duration of wound healing in the two groups. RESULTS: In the VAC group, the size of wound decreased from 60.2+/-59.1 cm2 to 29.7+/-18.8 cm2 (p=0.001). In the control group, it decreased from 60.3+/-83.3 cm2 to 34.4+/-47.6 cm2 (p=0.04). For formation of granulation, it increased from 1.2+/-0.4 to 2.7+/-0.6 (p=0.001) in the VAC group and from 1.2+/-0.4 to 2.4+/-0.5 in the control group. For the duration of healing, it took 17.5+/-8.3 days for the VAC group and 22.9+/-22.0 days in the control group (p=0.857). However there were no statistically significant differences in all the parameters between the 2 groups (p>0.05). CONCLUSION: The clinical application of VAC to difficult wound yield comparable results in terms of a decrease in wound size, formation of granulation, and the duration of healing. VAC dressing could be an alternative treatment option for a difficult wound considering the advantage of saving medical human resources.
