A Novel Fascial Flap Technique After Inguinal Complete Lymph Node Dissection for Melanoma.

ABSTRACT

INTRODUCTION: Inguinal complete lymph node dissection (CLND) for metastatic melanoma exposes the femoral vein and artery. To protect femoral vessels while preserving the sartorius muscle, we developed a novel sartorius and adductor fascial flap (SAFF) technique for coverage. METHODS: The SAFF technique includes dissection of fascia off sartorius and/or adductor muscles, rotation over femoral vasculature, and suturing into place. Patients who underwent inguinal CLND with SAFF for melanoma at our institution were identified retrospectively from a prospectively-collected database. Patient characteristics and post-operative outcomes were obtained. Multivariate logistic regression assessed associations of palpable and non-palpable disease with wound complications. RESULTS: From 2008 to 2019, 51 patients underwent CLND with SAFF. Median age was 62 years, and 59% were female. Thirty-one (61%) patients were presented with palpable disease and 20 (39%) had non-palpable disease. Fifty-five percent (95% confidence interval CI 40%-69%) experienced at least one wound complication wound infection was most common (45%; 95% CI 31%-60%), while bleeding was the least (2%; 95% CI 0.05%-11%). Complications were similar, with and without palpable disease. CONCLUSIONS: The SAFF procedure covers femoral vessels, minimizes bleeding, preserves the sartorius muscle, and uses standard surgical techniques easily adoptable by surgeons who perform inguinal CLND.
