Introduction: Adrenal neoplasms comprise about 10% of all tumours affecting this organ and constitute a significant, at first diagnostic and subsequently therapeutic, problem, especially since a relatively high proportion of neoplastic lesions are asymptomatic. The number of diagnosed metastases to adrenal glands is increasing. Surgical treatment involves both open surgery as well as laparoscopy.

Material and methods: There were 245 adrenalectomies performed at our centre due to various indications over the past four years. In 27 (11.5%) cases neoplasms were diagnosed in the final histopahtological examination. In 11 (40.7%) cases primary adrenal cortex tumours were diagnosed, metastases from other solid organ tumours were identified in another 12 (44.4%) patients, and rarer neoplasms were diagnosed in the remaning 4 (14.8%) subjects. Cases of malignant pheochromocytoma were not included in this report.

Results: Laparoscopic adrenalectomy was performed in 23 (85.2%) subjects, while the ramaining 4 (12.9%) patients were subject to open adrenalectomy (conversion to open procedure in one case). There were no deaths or significant complications in the perioperative period. Comparing mean duration of open (140 minutes) and laparoscopic (190 minutes) procedures yielded a statistically significant difference (p = 0.02). There was no statistically significant difference found in the duration of operation with regard to laparoscopic adrenalectomies of tumours less than 50 mm and over 55 mm in diameter (p = 0.16).

Conclusions: Laparoscopic adrenalectomy is a safe and effective method of treatment of adrenal tumours. Its oncological completeness is comparable (to open surgery) when performed by experienced surgical teams. Laparoscopy is the reason for the smooth postoperative course observed in most patients.
