Crossing the Threshold to Emergency Surgery: Robot-Assisted Adrenalectomy for Refractory Pheochromocytoma Crisis

Pheochromocytoma crisis can make conventional adrenergic preparation impossible and force consideration of adrenalectomy before physiologic recovery. This narrative review synthesizes the evidence that informs the transition from continued stabilization to nondeferrable tumor removal. Emergency presentation alone does not constitute an operative indication. When hemorrhage is controlled and cardiovascular and extracardiac organ function improved, surgery should be deferred until preparation is completed. Uncontrolled bleeding, expanding hematoma, or life-threatening compression requires immediate source-control assessment. Transcatheter arterial embolization may provide a bridge to elective adrenalectomy in selected hemorrhagic presentations. In nonhemorrhagic crisis, rescue adrenalectomy may be considered only when serial multidisciplinary reassessment shows persistent tumor-driven deterioration despite appropriate support, conventional preparation cannot be advanced safely, the lesion is localized and resectable, and organ injury remains potentially reversible. Mechanical circulatory support usually serves as a bridge to myocardial recovery and later surgery rather than as a routine platform for adrenalectomy. No validated temporal, hemodynamic, biochemical, or organ-failure threshold defines the point at which surgery becomes preferable to continued support. Operative access should therefore be selected only after the indication for surgery has been established and should reflect anatomy, physiologic tolerance, institutional expertise, and immediate conversion capability.
