Summary
Brief summary (as posted)
Laparoscopic adrenalectomy has become the gold standard operation for non-malignant adrenal tumors replacing open adrenalectomy. The most popular lateral transperitoneal laparoscopic adrenalectomy (LTLA) approach has been recently challenged by an increasing popularity of the posterior retroperitoneoscopic adrenalectomy (PRA) approach which is believed by many surgeons as an easy to learn, reproducible and beneficial for patients. However, this belief is not evidence-based, so far. The aim of this study is to clarify if PRA is superior to the LTLA as minimally invasive approach to small and benign adrenal tumors.
