Aim. The main goal of the analysis is to evaluate the effectiveness of using the videoscopic method of lymph node dissection for the patients with metastatic lesions of regional inguinal-femoral lymph nodes.
Material and methods. From 2013 to 2016 in Saint Petersburg Scientific and Practical Oncological Center 86 endovideoscopic inguinal-hip lymphadenectomies were performed for the patients with skin melanoma. The average time of operative intervention for standard lymphadenectomy was 100 min. (80–120 min.), using videoscopic equipment –120 min. (100–140 min.). The number of lymph nodes removed using both methods was not significantly different and averaged 11 (9–15). Intraoperative blood loss was comparable in both groups and did not exceed 50-100 ml.
Results. Median duration of the supervision before the interim analysis was 15 months. No local recurrence was obtained in any of the groups. The use of the videoscopic technique allowed to reduce the incidence of postoperative gray formation almost four times: from 28,2% to 6,4%, and also to reduce the duration of the presence of lymphorrhea: from 3 weeks to less than one week for groups of standard and minimally invasive surgery, respectively.
Conclusion. Video endoscopic inguinal-femoral lymphadenectomy is an effective surgical technique that allows achieving results comparable to the open (standard) technique of an operation, corresponding to all levels of oncological radicalism.
