Impact of laparoscopy on the management of adrenal diseases. A retrospective study of 220 patients

OBJECTIVE: Soon after its introduction in 1992, laparoscopic adrenalectomy became the gold standard in the surgical management of most adrenal tumors. The aim of this study was to assess the influence of laparoscopy on surgical indications. PATIENTS AND METHODS: Between 1994 and 2003, 220 adrenalectomies were performed, 179 among them by a laparoscopic approach. There were 137 females and 83 males. The mean age was 53 years (range 15-83 years). RESULTS: The indications of adrenalectomy were: Cushing syndrome 18%, pheochromocytoma 31%, Conn syndrome 16%, incidentaloma 21%, and malignant tumours 13%. Laparoscopic approach was performed in 81% of the cases and the conversion rate was 11%. There were 3 postoperative deaths (2 after laparoscopy). The mean hospital stay was 7.6 days in the laparoscopic group, and 13.6 days in the open surgery group. CONCLUSIONS: This study is consistent with the findings of the literature supporting that there are no indications for the open procedure in case of small benign lesions. The video-asisted adrenalectomy had not changed the management of the adrenal incidentaloma. Today, the laparoscopic approach seems to be adapted also for malignant disease.
