This paper reports the experience of five Belgian surgical teams with 18 videoendoscopic adrenalectomies performed on 16 patients between October 1993 and May 1995. The adrenal gland diseases were pheochromocytoma (4 patients), primary hyperaldosteronism (2 cases), Cushing's adenoma (2 cases), Cushing's disease (1 case), nonfunctional adenoma (3 cases), single metastasis from adenocarcinoma (2 cases), functional adenoma with dehydro-epiandrostenedione (DHEAS) and cortisol hypersecretion (1 case), ACTH secreting metastases from a thymoma (1 case) Two patients underwent bilateral adrenalectomies. Eleven left and three right adrenal glands were removed in 14 other patients. The eight women and eight men range in age from 17 to 72 years (median 47). Six patients demonstrated a body mass index greater than 30. Median tumor size was 3 cm (range 1.3 - 5). Laparoscopic adrenalectomy was successful in 14 patients (87%). The median duration of the procedure was 132 minutes (range 59-360). The median postoperative stay was 6 days (range 2-13). No patient required blood transfusion. We conclude that the videoscopic approach can safely be used for surgical removal of adrenal lesions. However this approach should be performed by surgeons well versed in the techniques of open adrenalectomy for endocrine disorders, but also well trained in videoendoscopic surgery.
