Laparoscopic anterior adrenalectomy for the treatment of adrenal metastases.

Aim of this study was to evaluate the results in 6 patients undergoing laparoscopic adrenalectomy for the treatment of solitary adrenal gland metastases. One hundred forty-five patients underwent laparoscopic adrenalectomy by transperitoneal anterior approach. In 6 patients the indication was the presence of a solitary adrenal gland metastasis. Primary tumors were the following: truncal melanoma, gastric cancer, renal cancer, lung cancer, and breast cancer. Mean age was 57 years (range 44-70 years). Three patients underwent right adrenalectomy and 3 patients a left adrenalectomy. No conversion to open surgery occurred. No mortality or intraoperative complications were observed. Mean operative time was 103 minutes (range 70-150) for right adrenalectomy and 170 minutes (range 90-280) for left adrenalectomy. No postoperative complications occurred. Mean diameter of the tumor was 3.5 cm (range 2-5 cm). Tumor free margins were obtained in every case. Mean hospital stay was 2 days (range 2-3 days). At follow-up, 2 patients have died of systemic dissemination of the disease, one 15 months and one 24 months after the operation. The remaining 4 patients are alive and disease free at a mean follow-up of 7 months (range 4-11 months). So far, no port site metastases or local recurrence have been observed. In our experience adrenal gland metastasis can be treated safely and effectively by the laparoscopic transperitoneal anterior approach.
