RESUMO
Secondary healing of complicated vulvar and groin wounds is a major challenge due to its moist condition and at risk of contamination by colonic flora. Vacuum assisted closure is the controlled application of sub-atmospheric pressure to the local wound environment using a sealed dressing connected to a vacuum pump. MATERIALS AND METHODS: The NPWT consists of an open-pore polyurethane ether foam sponge, an adhesive cover, fluid collection system, and suction pump that generates negative pressure. Direct application of sponge to blood vessels, bone, nerves or intact skin is avoided. The dressing and tubing are changed every 48-72 hours. RESULTS: Eight patients had NPWT following the vulva and/or groin surgery. Pain during removal of the sponge was the main adverse event requiring narcotic analgesia. All wounds healed completely. One patient is dead of disease progression. Others are alive without disease at four to 48 months. CONCLUSION: Wound breakdown in vulvar and groin surgery is an infrequent occurrence because of the rarity of full radical excision for vulva cancer and infralevator pelvic exenterative surgery. The present experience with NPWT was favourable.
