Summary
Surgical resection of pheochromocytoma and paraganglioma is safe and effective. Advances in diagnosis, localization, and hemodynamic control now allow for minimally invasive surgical approaches.
Area of Science:
- Endocrinology
- Surgical Oncology
Background:
- Pheochromocytoma and paraganglioma management has advanced.
- Surgical resection is a primary treatment.
- Assessing outcomes and surgical approaches is crucial.
Purpose of the Study:
- To review the management and outcomes of 110 patients with pheochromocytoma or paraganglioma.
- To assess surgical resection feasibility using posterior or laparoscopic approaches.
Main Methods:
- Retrospective review of patient records (1980-1992).
- Data collected on demographics, symptoms, diagnostics, and perioperative management.
- Tumor characteristics and patient outcomes were analyzed.
Main Results:
- Headaches, sweating, and palpitations were common symptoms.
- Urinary metanephrines and vanillylmandelic acid showed 98% sensitivity.
- Computed tomography (CT) scan had high predictive values for tumor localization.
- Alpha- and beta-blockade prevented intraoperative hypertension complications.
- Perioperative mortality was <1%, morbidity 16%.
- Over 90% achieved normotension post-surgery.
Conclusions:
- Transabdominal surgical resection is safe with short hospital stays.
- Current diagnostic and management strategies support posterior or laparoscopic approaches.
- Technical proficiency is essential for minimally invasive techniques.
