Para-aortic retroperitoneal robotic assisted laparoscopic schwannoma excision

Schwannomas are benign tumors primarily managed with surgical excision. Patient positioning, port placement, and adjuvant modalities are critical to achieve successful and safe surgical operations. In this case, a left ureteral stent was placed and the patient then placed in right lateral decubitus position. Four robotic ports were placed midline, evenly spaced between the falciform ligament and pubis. A modified mattox maneuver was executed, exposing the mass and allowing for complete excision without damage to surrounding structures. An enbloc complete excision of schwannoma without injury to surrounding structures was completed. This case highlights the importance of preoperative planning, specifically patient/port positioning and stent placement.
