RESUMEN
PURPOSE: Given the availability of laparoscopy and the rising detection of incidentalomas, indications for adrenalectomy may be changing. The Endocrine Surgery Section of the Spanish Association of Surgeons designed a survey to assess its indications, techniques, and results in Spanish Surgical Departments. METHODS: Collected data included hospital and department type, yearly hospital volume of procedures; location studies and preoperative preparation performed, indications, surgical approach and instruments used, and results in terms of morbidity and overall hospital stay. The analysis included a comparison between results of high- or low-volume centers and surgeons, using the Student's t test for quantitative and chi-square test for qualitative variables. Level of significance was set at 0.05. RESULTS: Nineteen centers returned the questionnaire, including 155 adrenalectomies performed in 2008. Most frequent indications were pheochromocytoma (23.2%), aldosteronoma (16.7%), incidentaloma (12.2%), metastasis (10.3%), Cushing adenoma (9.6%), and carcinoma (3.8%). Laparoscopy was performed in 83.9% of cases (9.4% required conversion to laparotomy). Four patients required urgent reoperation. Average hospital stay: 4.6 days (3.3 days after laparoscopy, 7 days after laparotomy). High-volume centers had a greater proportion of laparoscopically treated cases (p = 0.008), more malignant lesions treated (p = 0.03), a shorter overall stay (p < 0.0001), and a shorter stay after laparotomic adrenalectomy (p = 0.01). High-volume surgeons had similar results, and less in-hospital morbidity (p = 0.02). CONCLUSIONS: In Spain, adrenalectomy is performed in hospitals of varying complexity. Laparoscopic approach is the rule, with good results in terms of morbidity and stay. High-volume centers and surgeons had best results in terms of use of minimally invasive surgery and hospital stay.
