Advantages of using robotic Da Vinci® system for unilateral adrenalectomy:: early results

Study aim. - The goal of this study was to report the early results of unilateral transperitoneal adrenalectomy using robotic Da Vinci(R) system, and to compare them to the results of the laparoscopic standard adrenalectomy. Methods. - Prospective study included all patients operated on for unilateral laparoscopic or robotic adrenalectomy from November 2000 to November 2002. Results. - Twenty-eight patients underwent unilateral adrenalectomy using either standard laparoscopy (14 patients) or robotic Da Vinci(R) system (14 patients). Mean duration of robotic adrenalectomy seemed to be longer than standard laparoscopy (111 vs. 83 min; P = 0.057). This tendency decreased while surgeons' experience was increasing. Mean duration of operating room activity was similar for both types of surgery. Peroperative events without conversion, conversion rate (7%), drainage, morbidity (21%), duration of hospitalisation were similar for both types of surgery. Duration of standard laparoscopic adrenalectomy was positively correlated to patients body mass index. This correlation was absent in patients operated on by robotic Da Vinci(R) system. Conclusion. - This preliminary study found no objective data demonstrating that robotic Da Vinci(R) system was superior to standard laparoscopic approach for unilateral adrenalectomy. However, we think that it is necessary to continue further evaluation of this system to demonstrate its possible superiority. (C) 2003 tditions scientifiques et medicales Elsevier SAS.
