Laparoscopic adrenalectomy for pheochromocytoma

We reviewed 10 cases of laparoscopic adrenalectomy for pheochromocytoma and compared the results with those of a recent series of 11 patients who underwent open adrenalectomy. Of the 10 cases, the tumor was removed successfully in all cases except in one case with laparoscopy that required open laparotomy. A pair of laparoscopic coagulating scissors was utilized in all except the initial two cases. In the laparoscopy group (excluding the initial two cases and the case that required conversion to open surgery), mean operative time and blood loss were 145 min and 55 ml, respectively. No significant difference was observed in mean operative time between the laparoscopy group and the open surgery group (165 min for open surgery). Mean blood loss of the laparoscopy group was significantly less than that of the open surgery group (330 ml for open surgery, P = 0.01). Mean intervals to first ambulation and oral intake, and postoperative hospital stay of the laparoscopy group, tended to be less than those of the open surgery group, although no statistical significance was observed (2.3 versus 3.2 d, 2.9 versus 3.6 d, and 12 versus 14 d, respectively). We conclude that laparoscopic adrenalectomy for pheochromocytoma is equally effective and less invasive than open adrenalectomy and should be considered the therapy of choice even for pheochromocytoma.
