Numerous approaches have been employed to treat chronic lymphocele and cutaneous lymphatic fistulas (LFs) with little success. Given a high incidence and substantial consequences for patients, there is an ongoing demand for effective therapeutic and preventive strategies. The aim of this study was to evaluate the results after microscopic lymphatic ligation (MLL) and lymphovenous anastomosis (LVA) as a therapeutic and preventive approach in this context.
Methods: Demographic data, surgical characteristics, complications, and the overall outcome of all patients undergoing surgery for postoperative LF from 2014 to 2019 were collected retrospectively. Patients were categorized in accordance with predefined inclusion/exclusion criteria and with their treatment. Statistical analysis was conducted using descriptive, summary statistics to identify a central tendency.
Results: Thirty-four patients underwent indocyanine-green-lymphangiography guided revision surgery for LF. Two patients were lost to follow-up at 6 months. LF was successfully treated in all patients (n = 32) with a multimodal approach. Only MLL was performed in 22 patients and MLL/LVA in 10 patients. LF resolved in 78% of all patients with MLL only or MLL/LVA. In the remaining 22%, LF resolved after additional sclerotherapy within 3 months.
Conclusions: Treatment of LF should follow a standardized staged surgical approach to optimize outcome. LF was treated successfully in all our patients. We therefore propose a multimodal interdisciplinary approach to this common clinical problem that includes adjunctive sclerotherapy.
