ロボット支援後腹膜腫瘍切除術：ビデオ紹介

The utility of robotic platform remains relatively unexplored in the context of retroperitoneal tumors. The location and complexity of neurovascular anatomy pose additional challenges for surgical planning. Herein, we present the case of a 56-year-old male with a 9 × 7-cm retroperitoneal tumor located within the right iliopsoas muscle, without intraforaminal extent. The surgery was performed using the da Vinci Xi Surgical System (Intuitive Surgical, Inc.). The patient was placed in the left lateral position. Intraoperative and postoperative recovery was uneventful. A transient sensory deficit was noted in the right lower limb, which gradually resolved completely. The patient was discharged on postoperative day 4. Histopathology report confirmed a schwannoma with negative margins. At 1-year follow-up, the patient is doing well with no evidence of disease recurrence. Robotic resection of retroperitoneal tumors appears to be a feasible and safe approach. Proper planning and execution are essential for the successful completion of the surgery and achieving excellent outcomes.
