Safety and feasibility of single-incision radical vulvectomy: a novel approach for the treatment of vulvar cancer.
Background
In the process of decreasing the morbidity of wound-related complications after vulvectomy and IL for treating vulvar malignancy, we performed a novel surgical procedure-single-incision radical vulvectomy (SIRV). Here, we share our initial experience and report its safety and feasibility.


Methods
Patients with advanced local vulvar tumors were sequentially enrolled in this prospective cohort study to undergo SIRV. While performing SIRV, routine radical vulvectomies were performed first. Subsequently, the flaps of the bridge area between the vulvectomy incisions and femoral triangles were separated and the lymph nodes underneath were removed. Anterior working spaces (AWS) before the femoral triangle were then made. The saphenous vein was carefully identified and retained, while the superficial and deep inguinal lymph nodes were removed from the medial to the lateral sides. After careful hemostasis, the wounds were sutured. Patient demographics, clinical data, pathologic data, operation time, node count, and complications were recorded.


Results
Ten patients underwent SIRV for vulvar cancer. Average hospital stay was 11.70±3.16 (range, 9-13) days. The average number of harvested lymph nodes was 7.59±3.62 (range, 3-15) and 15.14±3.63 (range, 11-20) for per side or both sides of the groin. Blood loss was ≤35 mL. Three patients developed inguinal lymphoceles and underwent needle aspirations. Two patients had impaired wound healing and achieved healing after dressing change. No other postoperative complications were noted during follow-up.


Conclusions
Compared with conventional open inguinal lymphadenectomy (COIL) and video endoscopic inguinal lymphadenectomy (VEIL), SIRV is a more minimally invasive procedure. Our short-term observations showed that SIRV is safe and feasible and has good future application prospects for vulvar cancer. However, definitive conclusions cannot be made. Therefore, long-term oncologic outcomes and large-scale clinical trials are warranted.
