The V-Y gluteal fold advancement flap. Outcomes following radical surgery for vulvar malignancies

Objective: To evaluate the feasibility and complication rate of the V-Y gluteal fold flap in surgery for vulvar cancer. Methods: From June 2015 to June 2018, 62 patients surgically treated for vulvar cancer were included in the study. Twenty-three (37.1%) underwent plastic reconstructive surgery with V-Y advancement flaps. Results: The mean surgical time was longer for patients undergoing V-Y flap surgery. The margins were positive in six patients (9.7%), close (<8 mm) in 10 (16.1%), and adequate (>8 mm) in 46 (74.2%). Six (9.7%) patients had dehiscence and two (3.2%) patients suffered from necrosis. In patients undergoing V-Y flap reconstruction, two (8.7%) had a wound dehiscence, no patients had necrosis. In patients undergoing direct closure, four (10.3%) had wound dehiscence and two (5.1%) had necrosis. Conclusions: V-Y gluteal fold advancement technique is a safe procedure, performed in a single surgical session with minimal increase in surgical time and low wound healing complications. Use of this technique was correlated with an increased rate of adequate surgical margins (<8 mm) and reduced need for adjuvant radiotherapy.
