[Fluorescence-guided Lymph Vessel Sealing in Systematic Nodal Dissection: a New Surgical Technique to Prevent Lymphorrhea and Lymphocele.] / Fluoreszenzgesteuerte Lymphgefäßversiegelung bei der systematischen Lymphknotendissektion zur Vermeidung von Lymphfisteln und Lymphozelen.

INTRODUCTION: The primary morbidities of inguinal and axillary systematic nodal dissection are lymphatic fistulas and seromas. Intraoperative fluorescence imaging-guided sealing of lymph vessels may prevent these postoperative complications. METHODS: Indocyanine dye was injected intracutaneously into the distal limb before the beginning of the lymphadenectomy. Systematic nodal dissection was performed according to standard protocols. Near-infrared imaging was applied throughout the procedure and real-time fluorescence-guided lymph vessel sealing was performed. RESULTS: Fluorescence-guided lymph vessel sealing was implemented in three patients undergoing axillary systematic lymph node dissection. No adverse events occurred following fluorescence dye injection. All patients could be discharged free of wound complications. CONCLUSION: Fluorescence-guided lymph vessel sealing might be a promising new technique for preventing lymphatic fistulas and lymphocele after systematic lymphadenectomy.
