[Laparoscopic adrenalectomy for Cushing's syndrome: a study of comparisons between laparoscopic and open adrenalectomy, and laparoscopic adrenalectomy for differing adrenal tumors].
In order to evaluate the utility of laparoscopic adrenalectomy for Cushing's syndrome, the results of 6 laparoscopic adrenalectomies for Cushing's syndrome were compared with those of 34 other laparoscopic adrenalectomies, consisting of 7 pre-Cushing's syndromes, 13 primary aldosteronisms, and 14 non-functioning adrenal tumors. The results were also compared with 5 open adrenalectomies for Cushing's syndrome. The results of the laparoscopic adrenalectomies for Cushing's syndrome were as follows: the mean operating time was 216 +/- 46 min, and the mean estimated blood loss was 180 +/- 194 ml. From the third patient, an ultrasonic surgical system was used and the estimated blood loss decreased significantly. The ultrasonic surgical system, together with a more experienced surgical technique, also cut down the operating times. During surgical intervention, 2 complications occurred; a hemorrhage of more than 500 ml in one patient, and splenic injury in another, which was treated by compression. Postoperative complications occurred in 2 patients; paralytic ileus in one, and abdominal pain due to the pneumoperitoneum in the other. All patients except 2 patients with vertebral fracture began oral intake and ambulation 1 to 4 days postoperatively, and resumed normal daily activity on postoperative day 5 to 7. Compared with the laparoscopic adrenalectomies for the other adrenal tumors, the operating time and estimated blood loss in the Cushing's syndrome patients was not substantially different, though postoperative recovery was slightly longer. When compared with the open adrenalectomies, the operating time was longer, but the postoperative recovery period was significantly shorter. We conclude that with careful surgical intervention, experience of technique, and the introduction of proper equipment, a laparoscopic adrenalectomy for Cushing's syndrome can be performed as less-invasively as a laparoscopic adrenalectomy is for the other adrenal tumors. Furthermore, our findings suggest that laparoscopic adrenalectomy for Cushing's syndrome is likelier to have better postoperative results than conventional procedures, including a more rapid recovery to normal daily activity.
