title: Pheochromocytoma: laparoscopic approach with CO2 and helium pneumoperitoneum.
abstract: A number of different surgical approaches have been devised for adrenalectomy in patients with pheochromocytoma. The anterior transabdominal approach was at one time considered a source of postoperative morbidity; the advent of laparoscopy however, may result in a resurgence in its use. The laparoscopic approach was used with a CO2 pneumoperitoneum in one patient with a left pheochromocytoma, and using a helium pneumoperitoneum in another with bilateral pheochromocytoma. The left adrenalectomy took 135 minutes to perform and the total bilateral adrenalectomy 330 minutes. No transfusion was necessary. The postoperative stay was 4 days for both patients. To prevent the risk of CO2 retention during extended laparoscopic procedures, helium can serve as an alternative gas, as was documented in the patient who underwent total adrenalectomy. Unilateral or bilateral resection of pheochromocytoma can safely be performed laparoscopically and has the advantage of avoiding both the muscular trauma related to laparotomy and the rib resection necessary for the extraperitoneal approach.
