          Abstract

          We describe the case of a patient affected by multiple endocrine neoplasia type IIA with a new diagnosis of an asymptomatic right pheochromocytoma. The patient underwent laparoscopic adrenalectomy with adrenal sparing. The removal of the tumor was successful with preservation of about one third of the adrenal gland. At the time of the last follow-up, the patient is well with partial hypoadrenalism without replacement therapy. The limitations to cortical-sparing adrenalectomy imposed by traditional open surgery (small tumor with peripheral location) can be reconsidered using the laparoscopic approach. Laparoscopic cortical-sparing adrenalectomy should become the gold standard for treatment of bilateral pheochromocytoma. The advantages of this technique are its efficacy and its reduced invasiveness with a low rate of complications either during the operation or in the postoperative period. Moreover, the preservation of a portion of the adrenal cortex may prevent the need for a life-long steroid replacement therapy.

            Preserved adrenocortical function after laparoscopic bilateral adrenal sparing surgery for hereditary pheochromocytoma.

            Familial pheochromocytoma, increasingly diagnosed in asymptomatic subjects with inherited syndromes such as multiple endocrine neoplasia type 2 and Von Hippel-Lindau disease, is frequently bilateral and multifocal, but very rarely malignant. Therefore, bilateral adrenalectomy and subsequent lifelong steroid replacement, with its attendant side effects, is not desirable. Minimally invasive adrenal sparing surgery by means of laparoscopy was explored for the treatment of bilateral pheochromocytoma. We report on the cure rate and adrenocortical function in a series of patients treated accordingly. Four patients (three male, one female, ages 9-60 yr) with hereditary bilateral adrenal pheochromocytoma were treated by laparoscopic surgery in an organ sparing fashion. Postoperatively, all patients were reevaluated for complete tumor removal and for adrenocortical function. Two to 24 months after surgery, all patients were normotensive, had normal sodium potassium, glucose, aldosterone, renin, and cortisol serum concentrations, 24-h excretion of norepinephrine, epinephrine, and vanillylmandelic acid. Abdominal magnetic resonance imaging (n = 3) and computed tomographic scan (n = 1) disclosed no remnant or relapsing tumor tissue. ACTH stimulation testing resulted in normal cortisol responses. By adrenal sparing laparoscopic surgery not only bilateral pheochromocytoma can be successfully removed, but also adrenocortical function preserved. This may become the treatment of choice for familial pheochromocytoma.
