Objective: The objective of this study was to evaluate augmented reality-assisted single-incision laparoscopic adrenalectomy (AR-SILA) and compare with pure SILA. Materials and Methods: Between January 2009 and March 2012, a total of 19 patients had received SILA. Eight cases were AR-SILA and the others were pure SILA. Results: Eight AR-SILA procedures and 11 SILA were successfully completed. There was no significant difference between the two groups in terms of age, body mass index, and tumor size. Operative times were shorter in the AR-SILA group (102.5 ± 12.8 vs. 150.9 ± 46.3, P = 0.005). The mean blood loss in the AR-SILA group was slightly less than that in the SILA group (60.0 ± 25.6 vs. 109.1 ± 80.1, P = 0.129). There was neither postoperative mortality nor morbidity at the time of discharge and during follow-up. Conclusion: AR-SILA provides important intraoperative information for surgeons to recognize where the pathological lesions and vessels are located beyond the surgeon's direct vision. It made SILA safer and easier.

Laparoscopic adrenalectomy offers distinct benefits to patients and has now become the gold standard for the removal of adrenal lesions. Nonetheless, the procedure poses a challenge for surgeons in regards to the maneuverability of instruments, the two-dimensional operating field and the counterintuitive movements. This study reports our experience using the Zeus robotic surgical system in laparoscopic adrenalectomy compared with traditional laparoscopic adrenalectomy.From January 2003 to February 2005, a total of 12 patients were prospectively enrolled to receive robot-assisted laparoscopic adrenalectomy (RALA) or traditional laparoscopic adrenalectomy (TLA). The time necessary for robotic setup and operation was recorded, as well as complications, technical problems, postoperative hospital stay, morbidity, and mortality.Five RALA procedures and seven TLA were successfully completed. There was no significant difference between the groups in terms of age, body mass index, and tumor size. Resection times were longer in the RALA group (168.0 +/- 30.7 min vs. 131.4 +/- 29.0 min, p = 0.05). There were no perioperative complications. There was neither postoperative mortality nor morbidity at the time of discharge and during one year follow-up.RALA is as safe and technically feasible as TLA, It provides a real benefit for the surgeon with the three dimensional view, a comfortable sitting position, the elimination of the surgeon's tremor, and increased degrees of freedom of the operative instruments compared with TLA. However, patient outcomes and operative costs should be evaluated further.

Robotic surgical systems have recently been used to perform laparoscopic procedures in several diseases. We report the initial 2 cases of robotic-assisted laparoscopic adrenalectomy from Taiwan. Both cases were performed transperitoneally using the ZEUS surgical system (Intuitive Surgical Inc., Mountain View, CA, USA). This system consists of 3 interactive robotic arms and a remote control unit, allowing the surgeon to control the 2 instrument arms and 1 camera arm via a surgical console. The key component of the ZEUS surgical system is the MicroWrist (Computer Motion Inc., CA, USA) technology, which allows the surgeon to roll, pitch and grip laparoscopic tools freely and provides the surgeon with a 3-dimensional view of the operative field. Postoperative courses were uneventful and the patients were discharged on the third and fourth postoperative days, respectively. No intraoperative or postoperative complications were encountered. These cases suggest that robotic-assisted laparoscopic adrenalectomy is technically feasible, and that the role of robotic surgery in urologic laparoscopy is likely to expand in Taiwan.
