Robot-assisted retroperitoneal lymph node dissection: Initial experience in Japan

Abstract

For patients with testicular tumors who need the surgical management, open retroperitoneal lymph node dissection (O-RPLND) is considered the gold standard treatment. However, recently, robot-assisted RPLND (R-RPLND) has gained popularity as a minimally invasive therapy alternative to O-RPLND and laparoscopic RPLND. Here, we report the case of a 32-year-old man presenting with a left testicular teratoma with several enlarged left para-aortic lymph nodes. After the orchiectomy, the patient underwent R-RPLND with an operation time of 279 min, console time of 189 min, bleeding volume of 59 mL, and no significant complications, resulting in a successful outcome. To the best of our knowledge, this is the first reported case of R-RPLND in Japan. Based on our experience, R-RPLND may provide safe and effective outcomes; however, further research is required before the widespread implementation of this technique.
