Abstract
Objective:
To compare the efficacy of laparoscopic adrenalectomy for pheochromocytoma with that of conventional open adrenalectomy for pheochromocytoma and laparoscopic surgery for other adrenal tumors.
Patients and Methods:
Fifty-four patients with adrenal tumors, including 10 cases of pheochromocytoma, 18 cases of Cushing's syndrome, 20 cases of primary aldosteronism, and 6 cases of nonfunctioning tumors, were evaluated. A historical group of 7 consecutive patients who underwent conventional open adrenalectomy for pheochromocytoma was also studied.
Results:
Laparoscopic adrenalectomy for pheochromocytoma was successful in 9 of the 10 patients. There was no difference in tumor size, operation time, estimated blood loss, or occurrence of hypertensive episodes during surgery between patients treated with laparoscopic procedures and those treated with open surgery. However, the number of days to first postoperative oral feeding and first ambulation, length of hospitalization, and number of patients requiring parenteral analgesics were significantly smaller after laparoscopic surgery than after open surgery. There was no significant difference in operation time, estimated blood loss, incidence of intraoperative complications, or postoperative recovery between patients who underwent laparoscopic adrenalectomy for pheochromocytoma and those who underwent laparoscopic surgery for other adrenal lesions.
Conclusions:
Laparoscopic adrenalectomy does not increase the specific risks associated with surgery for pheochromocytoma. It is a minimally invasive alternative to conventional open adrenalectomy.
