Abstract

Nowadays, the role of surgery in the treatment of adrenal incidentalomas (AI), considering their biologic behavior, is still debated. Surgery is mandatory in cases of hyperfunctioning adrenal masses, in the presence of suspect radiological malignancy, in cases of discordant computed tomography (CT) and scintigraphy findings and when the maximum diameter is 4 cm or more. On the other hand, studies have suggested relative inaccuracy of conventional CT in evaluating the size. The aim of this paper was to evaluate the safety and effectiveness of laparoscopic adrenalectomy (LA) in the treatment of AI by reviewing our experience. Over the period from 1995 to 2005 we laparoscopically managed 78 AI by anterior transperitoneal approach. Two LA (2.6%) were converted to open surgery. Neither intranor post-operative major complications were observed. The mean size of lesions was 5.5 cm (range 3–9). Twenty-one large adrenal lesions (exceeding 6 cm) were removed (27%). Definitive histology resulted as follows: adrenocortical adenoma (63), pheochromocytoma (5), nodular hyperplasia (4), myelolipoma (3), cysts (2), and adrenocortical carcinoma (1, with a size of 3 cm). The patients were followed-up by hormonal and radiological evaluation every 12 months (6 for malignancy); their follow-up (median 60.4 months, range 6–123) was uneventful. Also larger AI were treated safely. Laparoscopy has been safe and effective in the treatment of AI in our experience, according to specific literature.
