Abstract:Objective: To evaluate the efficacy of 3D vs. 2D laparoscope retroperitoneal lymph node dissection (LRPLND) for clinical stageⅠnonseminomatous germ cell tumors (NSGCTs). Method: From January 2009 to July 2021, 23 patients with clinicalstageⅠNSGCTsreceived LRPLND during 1-4weeks after orchiectomy. All of their clinical stage were stageⅠand NSGCTs were confirmed pathologically. The operating time, intraoperative blood loss, postoperative intestinal function recovery time and hospital stay were collected. Results: 3D laparoscope group had 15 cases. The mean surgical time was (185.0 ± 27.9) min. The mean intraoperative bleeding loss was (165.0 ± 35.3) mL.The mean postoperative intestinal function recovery time was (31.0 ± 8.2) h. The hospital stay was (7.0 ± 1.1) d. 2D laparoscope group had 12 cases.The mean surgical time was (230.0 ± 43.8) min.The mean intraoperative bleeding loss was (227.0 ± 48.6) mL. The mean postoperative intestinal function recovery time was (33.0 ± 7.3) h. The hospital stay was (8.0 ± 0.6) d. The mean follow-up period was 27 months. All patients revealed no evidence of recurrence or distant metastasis. Conclusion: RPLND technology under 3D laparoscope was feasible, which had an advantage of minimalinvasion and fast postoperative recovery. It was a reliable method to treat low differentiated nonseminomatous germ cell tumors.
