BackgroundRecent evidence supports the use of robotic surgery for the minimally invasive surgical management of adrenal masses.ObjectiveTo describe a contemporary step-by-step technique of robotic adrenalectomy (RA), to provide tips and tricks to help ensure a safe and effective implementation of the procedure, and to compare its outcomes with those of laparoscopic adrenalectomy (LA).Design, Setting, And ParticipantsWe retrospectively reviewed the medical charts of consecutive patients who underwent RA performed by a single surgeon between April 2010 and October 2013. LA cases performed by the same surgeon between January 2004 and May 2010 were considered the control group.Surgical ProcedureThe main steps of our current surgical technique for RA are described in this video tutorial: patient positioning, port placement, and robot docking; exposure of the adrenal gland; identification and control of the adrenal vein; circumferential dissection of the adrenal gland; and specimen retrieval and closure.Outcome Measurements And Statistical AnalysisDemographic parameters and main surgical outcomes were assessed.Results And LimitationsA total of 76 cases (RA: 30; LA: 46) were included in the analysis. Median tumor size on computed tomography (CT) was significantly larger in the LA group (3cm [interquartile range (IQR): 3] vs 4cm [IQR: 3]; p=0.002). A significantly lower median estimated blood loss was recorded for the robotic group (50ml [IQR: 50] vs 100ml [IQR: 288]; p=0.02). The RA group presented five minor complications (16.7%) and one major (Clavien 3b) complication (3.3%), whereas four minor complications (8.7%) and one major (Clavien 3b) complication (2.3%) were observed in the LA group. No significant difference was noted between groups in terms of malignant histology (p=0.66) and positive margin rate (p=0.60). Distribution of pheochromocytomas in the LA group was significantly higher than in the RA group (43.5% vs 16.7%; p=0.02).ConclusionsThe standardization of each surgical step optimizes the RA procedure. The robotic approach can be applied for a wide range of adrenal indications, recapitulating the safety and effectiveness of open surgery and potentially improving the outcomes of standard laparoscopy.Patient SummaryIn this report we detail our surgical technique for robotic removal of adrenal masses. This procedure has been standardized and can be offered to patients, with excellent outcomes.Copyright © 2014 European Association of Urology. Published by Elsevier B.V. All rights reserved.
