Laparoscopic partial adrenalectomy for recurrent pheochromocytoma after open partial adrenalectomy in von Hippel-Lindau disease

BACKGROUND AND PURPOSE: Unilateral total adrenalectomy is the standard treatment for benign unilateral adrenal tumors. Partial adrenalectomy has to be considered for bilateral adrenal tumors. Recently, our group has reported the feasibility of unilateral and bilateral partial adrenalectomy by means of laparoscopy. Now, we present a case of recurrent pheochromocytoma after open bilateral adrenalectomy and demonstrate that laparoscopic cortex-sparing surgery is feasible for a recurrence after open surgery. Case Report: At the age of 10 years, a boy was found to have bilateral adrenal pheochromocytoma and was treated by open bilateral partial adrenalectomy. Eight years later, the patient presented with palpitation, sweating, and severe hypertension. Investigations biochemically and radiologically demonstrated functional recurrent pheochromocytoma in the left adrenal gland. Genetic studies confirmed mutation of the von Hippel-Lindau (VHL) gene. The patient was prepared for surgery preoperatively by phenoxybenzamine and metropolol. The surgery was performed as planned, and the normal adrenal tissue was spared. The patient had an uneventful postoperative course. His blood pressure was normal on the day of discharge. CONCLUSIONS: In a specialized center with experienced laparoscopic surgeons, laparoscopic partial adrenalectomy for recurrent pheochromocytoma is feasible even after previous open surgery on the ipsilateral adrenal gland. Adrenal-sparing surgery is indicated in hereditary syndromes such as VHL and MEN II to avoid the problems of life-long steroid replacement. Recurrences have to be expected, but further surgery may be less difficult by the previous laparoscopic approach.
