OBJECTIVE: To report a safe, quick and reproducible technique of robotically assisted right adrenalectomy (RRA), developed by assessing the surgical anatomy of the right adrenal gland, its vascularity, and the surrounding structures, through a high definition, magnified three-dimensional view of the operating field provided by the da Vinci surgical system (Intuitive Surgical, Sunnyville CA, USA). PATIENTS AND METHODS: Four patients had RRA between January and July 2007 at the Vattikuti Urology Institute, for varied indications. We extensively reviewed published anatomical and surgical reports of the anatomy of the region to plan the surgical steps for RRA, careful reconfirming recognized anatomical facts and their probable significance. The surgical steps involved: (i) complete division of the hepatocolic ligament; (ii) definition of the right adreno-caval junction (ACJ); (iii) division of the right adrenal vein; (iv) dissection and removal of the adrenal gland circumferentially. The surgery was digitally recorded and reviewed. RESULTS: All the adrenalectomies were done transperitoneally through five ports, replicating predetermined surgical steps. There were no anaesthesia or surgery related events and no patient required conversion to open surgery. All the patients had an uneventful recovery and were discharged home 0-3 days after RRA. With increasing experience it was possible to reach the ACJ with minimal peripheral dissection. From a lateral approach, we visualized the adrenal vein travelling along the anterior portion of the gland before terminating at the inferior vena cava and the retrocaval location of the medial edge of the adrenal gland. The right adrenal vein (singular or duplicate) was the only surgically significant vessel, as the other vessels encountered were controlled with bipolar diathermy. CONCLUSIONS: Robotic assistance facilitated microdissection of fine anatomical planes around the right adrenal gland and provided direct access to the crucial ACJ. This technique permits ligation of the adrenal vein as an initial step, with no need to handle the adrenal gland. In the initial experience with four patients this technique was reproducible, regardless of indication or anatomical variance.
