Modified Gluteal Fold V-Y Advancement Flap for Reconstruction After Radical Vulvectomy.

Abstract

To describe the surgical technique of the V-Y cutaneous supra-fascial (modified) gluteal advancement flaps for reconstruction after radical vulvectomy and to assess the outcome of patients according to their clinical characteristics. Between January 2006 and July 2012, 36 V-Y flaps were performed in 21 patients to cover the defect after radical surgery of primary vulvar cancers. Surgery duration, blood loss, hospital stay, and wound healing were assessed according to patient age, body mass index (BMI), American Society of Anesthesiologists (ASA) score, and the initial defect size. Median patient age, BMI, and ASA score were 80 (range, 31-91), 28 (range, 18-36), 3 (range, 1-3), respectively. Median surgery duration and blood loss were 180 minutes (range, 60-275) and 400 mL (range, 100-1000), respectively. Median operating time was higher in patients ASA3 than ASA less than 3, 200 versus 120 minutes (P = 0.038). Median initial defect size was higher in patients with BMI greater than 28 than 28 or less, 92 versus 55 cm (P = 0.004). Local scar defect was observed in 16 patients (76%), mild, less than 10 cm in 10 patients. Median wound healing duration was higher in patients with bilateral than unilateral flap, 16 versus 9.5 days (P = 0.034). The V-Y cutaneous suprafascial gluteal advancement flap for vulvar reconstruction after vulvectomy is an easy, safe, and reliable procedure. However, even mild local scar defect after bilateral flap may impact on wound healing and hospital stay, in elderly and ASA3 patients.
