From the abstract
Retroperitoneal lymph node dissection (RPLND) is an established treatment option for clinical stage I-II non-seminomatous germ cell tumors (NSGCT), among which bilateral template dissection represents the most oncologically rigorous approach (1, 2). Robot-assisted RPLND has demonstrated reduced surgical morbidity while maintaining oncologic equivalence to open surgery (3).
Reported results
Operative time was 175 minutes with an estimated blood loss of 35 mL. The patient resumed oral intake on postoperative day 1 and was discharged on day 2 (VAS: 2) without complications. Thirty-two lymph nodes were retrieved; three harbored teratoma (pN1). At 36-month follow-up, the patient remains disease-free with normal tumor markers and no retroperitoneal recurrence.
Authors' conclusions
To our knowledge, this represents the first reported extraperitoneal single-port bilateral robot-assisted RPLND. This approach achieves oncologically thorough dissection while minimizing morbidity and facilitating rapid recovery.
