AIM: To evaluate outcomes of laparoscopic adrenalectomy (LA) and laparoendoscopic single-site surgery (LESS) for adrenal masses in the light of changing laparoscopic surgical techniques. MATERIALS AND METHODS: Seventy-three patients were analyzed retrospectively. There were 2 groups; group 1 included patients who had conventional transperitoneal LA and transperitoneal LESS, and group 2 included patients who had lateral retroperitoneal LA, retroperitoneal LA in prone position, and retroperitoneal LESS. Demographic data, urine 3-methoxy-4-hydroxymandelic acid, normetanephrine, epinephrine, serum cortisol, aldosterone, adrenocorticotropic hormone, American Society of Anesthesiologists score, side and size of mass, conversion to open surgery, complications, estimated blood loss, operation time, pathological results were recorded and analyzed. RESULTS: There was no difference in demographic data and serum parameters between both groups. Tumor size, estimated blood loss, operation time, transfusion rate and hospital stay were less for group 2 (p < 0.05, p = 0.0001). However, the complication rate was similar in both groups; in retroperitoneal prone position, the complication rate was less than for other surgical approaches, but statistically significant results could not be assessed. CONCLUSIONS: Even if the diameter of adrenal mass is larger than 6 cm, LA may be considered as the gold standard. The retroperitoneal approach especially in prone position may be a promising treatment method in the near future for adrenalectomy in selected patients.
