• To prospectively determine the oncological adequacy of robotic assisted video-endoscopic inguinal lymphadenectomy (RAVEIL).
PATIENTS AND METHODS
• Patients with T1-3N0 penile cancer were enrolled into a prospective phase I trial at a tertiary care institution from March 2010 to January 2012. All patients underwent an initial RAVEIL approach.
• Verification of adequacy of dissection was performed by an independent surgeon via a separate open incision at the conclusion of the RAVEIL procedure.
• Out of 10 patients, if more than two superficial inguinal fields with ≥2 nodes or more than four with ≥1 node remained within the superficial dissection field, the study would not proceed to phase II.
• Of 10 enrolled patients two had inguinal metastases and all positive nodes were detected by RAVEIL. The remaining eight patients had no metastases, with a mean of nine (range 5–21) left and nine (range 6–17) right nodes removed. One inguinal field RAVEIL was converted to an open dissection.
• The verifying surgeon confirmed that 18 of 19 inguinal fields (94.7% in nine patients) had an adequate dissection. Two benign nodes were found just beneath Scarpa’s fascia above the inguinal dissection field.
• Limitations of the study include an inability to determine decisively what specific wound complications were related to RAVEIL because of the protocol-specified creation of a small inguinal incision for verification of adequate dissection.
• RAVEIL allowed adequate staging of disease in the inguinal region among patients with penile cancer at risk for inguinal metastases.
