Abstract
INTRODUCTION: The rate of adrenal disease diagnosed is progressively increasing due to the diagnostic tools improvement. We analysed patients that underwent to adrenalectomy in our centre for different adrenal pathologies and we tried to established guidelines for the surgical therapy. METHODS: Demographic and clinical data were prospectively entered in a computerized endocrine surgery registry for all patients who underwent surgery for adrenal lesions at our institution over a 35-year period and statistical analyses was performed. RESULTS: Between 1986 and 2020, 502 patients underwent adrenalectomy: open adrenalectomy (OA) was performed in 104 patients (28,6%), laparoscopic adrenalectomy (LA) in 398 patients (71,4%). The rate of conversion to OA was 5,9% (21 patients). The mean operating time in laparoscopic approach was 84.3 min (range 40-180) while in open approach was 121.9 min (40-210). The average length of stay (LOS) for LA was 3.6 days, while for OA was 7.4 days. The time to return to normal activity for LA was 21 days while for OA was 37 days. CONCLUSIONS: The progressive increase in the number of adrenalectomies performed is due more to a better understanding of adrenal disease than to the availability of minimally invasive techniques. The choice of a laparoscopic approach should depend on the surgeon's experience, regardless the dimension of the lesion. Considering our long experience, we suggest OA for lesion of more of 6 cm, for malignant lesion with a diameter higher than 3 cm or with a pre-operatory evidence of invasion of the surrounding tissue.
