BACKGROUND AND PURPOSE: Laparoscopic retroperitoneal lymph node dissection (L-RPLND) is an alternative in patients with metastatic nonseminomatous germcell tumors (NSGCT) necessitating resection of residuals postchemotherapy. With the advancement of laparoscopic vascular surgery, prospective management of the great vessels has become feasible and safe. We present our experience with L-RPLND in NSGCT residuals with significant vascular involvement necessitating intracorporeal reconstruction. PATIENTS AND METHODS: We have retrospectively identified 19 NSGCT patients (mean age 27 years) who presented with residuals postchemotherapy. A bilateral L-RPLND was performed in all men. Infiltration of the great vessels was confirmed intraoperatively. Prospective vascular control and temporary clamping was performed in all cases. The vessel wall was reconstructed using vascular surgery techniques. All patients had at least clinical stages of IIA or higher. Follow-up was obtained in all. RESULTS: There were no conversions to open surgery. The mean size of the residuals after chemotherapy was 3.87 cm (1.5-9.7 cm). The mean blood loss was 310 mL (50-1000 mL). Mean hospital stay was 6 days (3-9 days). There were no perioperative complications exceeding grade II according to the Clavien-Dindo classification. Distant or in-field recurrence (mean observational period 18 months) did not develop in any patient. CONCLUSION: Laparoscopic RPLND may be considered a safe alternative concept for the management of post-chemotherapy NSGCT residuals involving the great vessels. Bilateral L-RPLND in patients with vascular infiltration is feasible and reproducible when laparoscopic vascular surgery can be reliably handled. All standard principles of open surgery are respected, and initial oncologic results are promising.
