Laparoscopic surgery and corticoadrenalomas.
BACKGROUND
Nowadays, laparoscopic adrenalectomy is the "gold standard" procedure for the treatment of benign lesions. However, the situation is not so clearcut when the issue is laparoscopic excision of malignant adrenal tumors. We present our results of laparoscopic adrenalectomy for treating malignant tumors over the past decade.


METHODS
Between October 1995 and June 2004, 131 consecutive laparoscopic adrenalectomies were performed on 120 patients (11 synchronous bilateral procedures). All patients underwent a standardized investigation protocol during their workup for surgery.


RESULTS
There were only two conversions to laparotomy (1.6%). Complications that occurred during the procedure were limited to six patients (5%). Postoperative 30-days mortality was nil. Postoperative complications occurred in five patients (4.7%) during the first 30 days of recovery. The median hospital stay for all patients was 2.5 days (range = 2-10 days). Twelve patients (9%) had a malignant tumor: nine corticoadrenalomas, one pleomorphic sarcoma, one metastatic deposit from a previously excised colonic cancer, and one malignant pheochromocytoma. At mean followup of 34 months, mean survival time was 42.3 months for corticoadrenalomas that had undergone laparoscopy versus 29.7 months for those who had had a laparotomy. Five of the nine patients are alive and well at a mean of 37 months following surgery. One patient developed pulmonary metastases one year postsurgery; they were responsive to mitotane. Five years later, the same patient had a reoperation for an intra-abdominal retrogastric recurrence of her tumor and continues to do well. Another patient developed pulmonary metastases 22 months following adrenalectomy. Two patients died of metastatic intra-abdominal disease 20 and 7 months postsurgery.


CONCLUSIONS
When laparoscopic surgery is to used for cancer treatment, caution is the rule to maintain the primary objective of securing a survival rate at least as high as that for open surgery, without increased risk of recurrence. Considering the results presented within this study, it seems that the laparoscopic removal of a corticoadrenaloma should not worsen the prognosis, provided the surgeon respects the primary rules of oncologic resectional surgery. Any surgical conditions that would preclude the strict application of these criteria are contraindications to a laparoscopic procedure.
