BACKGROUND: Laparoscopic adrenalectomy (LA) is unanimously recognized as the gold standard for the surgical treatment of adrenal lesions, but when to remove malignant lesions by this approach still remains controversial.
STUDY DESIGN: We reviewed all cases of LA for suspected adrenal metastases carried out in our hospital, trying to focus on what should be the ideal preoperative workup, so as to avoid unnecessary operations. The possible role of fine needle aspiration biopsy (FNAB) in selecting patients was evaluated.
RESULTS: Twenty-two patients underwent LA for suspected adrenal metastases from May 1994 to March 2003. Primary tumors were from lung in 14 cases, colon in 2 cases, kidney in 3 cases, thyroid in 2 cases, and breast in 1 case. LA was successfully performed in all but three cases. In 13 patients, 14 FNAB were performed: 8 cases proved to be true positive, 4 true negative, and 2 false negative. Final histology showed 6 cortical adenomas. Local relapse was present only in one patient, who died after 14 months. Of the metastatic patients, 8 are alive and free of disease after a mean followup of 39 months.
CONCLUSIONS: The most accurate workup is of the greatest importance in order to avoid unnecessary surgery for suspected adrenal metastases. The absence of false positives (FP) and the fairly high number of true positives (TP) does not justify the effort of performing FNAB routinely. Indeed, laparoscopic exploration, being simple and quick, allows optimal diagnosis at a low cost, even when histological definition cannot be obtained.
