Recent advances in the diagnosis and treatment of pheochromocytoma in children

Background The purpose of this study was to analyze the effects of changes in the diagnosis and treatment of pheochromocytoma in a pediatric population. Methods We reviewed the medical records of all children who had resection of pheochromocytoma or paraganglioma at a major children\u92s hospital since 1968. Results Fifteen children underwent surgery at 11.9 \ub1 4.2 years of age. Presenting symptoms included headache, hypertension, and sweating. Three children had a mutation of the succinate dehydrogenase enzyme, and 1 child had nonsyndromic, familial pheochromocytoma. The most sensitive diagnostic modalities included 24-hour urinary and plasma norepinephrine and 24-hour urinary total metanephrines, magnetic resonance imaging, and 123I\u96meta-iodobenzylguanidine scintigraphy. Laparoscopic cortical-sparing adrenalectomy was performed in 3 patients with von Hippel-Lindau disease. Compared with those with open procedures (n =3D 7), patients who had laparoscopic resection (n =3D 5) had a statistically shorter hospital length of stay, and time to eating ambulation. Conclusions The addition of 123I\u96meta-iodobenzylguanidine scanning, genetic testing, and laparoscopic surgery has changed the diagnosis and treatment of pheochromocytoma in children. Laparoscopic cortical-sparing adrenalectomy can be accomplished safely and is the preferred treatment for children at risk for multifocal disease
