Objective: Endoscopic adrenalectomy represents the "New Golden Standard" in the surgical treatment of benign adrenal lesions up to 6 cm. Open adrenalectomy is recommended for patients with suspected malignant disease and tumors larger than 6 cm.
Methods and material: The surgical technique of trans- and retroperitoneal adrenalectomy is described. Reviewing literature the importance of the endoscopic approach and its role in the surgical treatment of adrenal lesions is analyzed.
Results: As in open adrenalectomy different endoscopic approaches to the adrenals were developed: adrenal tumors can be removed endoscopically using a transperitoneal (patient in a supine or lateral decubitus position) or extraperitoneal route (patient in a lateral decubitus or prone position). Reviewing literature the endoscopic transperitoneal adrenalectomy is documented in 1425 patients. 4.6% (66 patients) had to be converted to an open procedure. Five hundred and forty-four tumors were removed by an extraperitoneal access. The conversion rate was 4.4% (24 patients).
Conclusion: The basis of excellent results are careful patient selection, evaluation and preoperative preparation in a center with experience in the open techniques and at least 20 endoscopic adrenalectomies per year.
