Total adrenalectomy was historically the standard of care for patients with hereditary syndromes, but this leads to lifelong steroid supplementation. Adrenal-sparing surgery has been described in the treatment of adrenal incidentaloma, aldosteronoma, isolated metastasis, and the hereditary pheochromocytomas of MEN2 and VHL. Synchronous bilateral laparoscopic partial adrenalectomy with intraoperative ultrasonography has been described for pheochromocytomas as safe and technically feasible, but the majority of bilateral lesions have been treated by staged operations. We report our experience of synchronous bilateral robotic partial adrenalectomy for multifocal bilateral adrenal pheochromocytomas. METHODS: A 36-year-old female with marfanoid habitus and biopsy-proven medullary thyroid cancer was found to have bilateral adrenal masses on staging workup. Laboratory results showed elevated serum metanephrines, and she was started on alpha blockade with phenoxybenzamine. Imaging revealed a 3 cm right adrenal mass with a separate area of 1 cm irregularity and a 2 cm left adrenal lesion. Bilateral robotic partial adrenalectomies were successfully performed using a 4-arm technique with the daVinci Xi robotic platform (Intuitive, Sunnyvale CA) and a 12mm assistant trocar at the umbilicus. The patient was positioned in full-flank positioning for each side with docking from the same side of the room. The midline subxiphoid robotic 8mm and the 12mm assistant trocars were used for both portions of the operation. RESULTS: Enucleation of the tumors was performed with a total operative time of 330 minutes and estimated blood loss of 50mL. Pathology revealed three pheochromocytomas, and the patient was started post-operatively on a steroid taper. She was referred for genetic counseling given suspicion for MEN2B syndrome. CONCLUSIONS: Bilateral adrenal-sparing surgery for pheochromocytoma is safe and feasible and may be achieved using a robotic 4-arm technique with linear trocar configuration with repositioning. This approach in patients with genetic predisposition to synchronous adrenal lesions may preclude or delay the need for lifelong steroid supplementation.
