PURPOSE: We report our experience with laparoscopic adrenalectomy in nine patients with pheochromocytoma and compare the morbidity with that of laparoscopic adrenalectomy for tumors of other pathology. PATIENTS AND METHODS: Between January 1997 and November 1999, nine patients underwent laparoscopic surgery for pheochromocytoma via a transperitoneal approach. Of the patients, eight had solitary tumors, and one presented with bilateral pheochromocytomas. The mean size of the tumors was 5.4 cm. The surgical outcomes of the 9 patients were compared with those of 28 patients with adrenal tumors of other pathology (primary aldosteronism in 15 patients, Cushing syndrome in 6, and nonfunctioning adenoma in 7) who underwent transperitoneal laparoscopic adrenalectomy during the same period. The mean size of the adrenal tumors of other pathology was 2.4 cm. RESULTS: In eight of the nine patients with pheochromocytoma, laparoscopic adrenalectomy was successful. The procedure was converted to open surgery in the patient with bilateral tumors because of uncontrollable hemorrhage. A hypertensive crisis with the systolic blood pressure >200 mm Hg occurred in 6 patients (67%), but the episode could be controlled by temporary discontinuation of tumor manipulation, administration of drugs, or both. In adrenalectomy for pheochromocytoma, the mean operative time was longer (199 v 177 minutes) and the mean estimated blood loss was greater (360 v 54 mL) than for tumors of other pathology. Blood transfusion was given to two patients with pheochromocytoma but to no patient with tumors of other pathology. The patients with adrenal tumors of other pathology could resume normal activity earlier (mean 18 v 26 days) than those with pheochromocytoma. CONCLUSION: The operation is more difficult and the morbidity is higher in laparoscopic adrenalectomy for pheochromocytoma than that for tumors of other pathology. An experienced team of surgeons with advanced laparoscopic skills and anesthesiologists is mandatory. In large tumors, great caution should be taken for intraoperative complications. Nevertheless, laparoscopic adrenalectomy is not contraindicated for pheochromocytoma and can be performed safely.
