BACKGROUND: The da Vinci robotic surgical telemanipulator has been utilized in several surgical specialties for varied procedures, and the users' experiences have been widely published. To date, no detailed system technical analyses have been performed. METHODS: A detailed review was performed of all publications and patents about the technical aspects of the da Vinci robotic system. RESULTS: Published technical literature on the da Vinci system highlight strengths and weaknesses of the robot design. While the system facilitates complex surgical operations and has a low malfunction rate, the lack of haptic (especially tactile) feedback and collisions between the robotic arms remain the major limitations of the system. Accurate, preplanned positioning of access ports is essential. CONCLUSION: Knowledge of the technical aspects of the da Vinci robot is important for optimal use. We confirmed the excellent system functionality and ease of use for surgeons without an engineering background. Research and development of the surgical robot has been predominant in the literature. Future trends address robot miniaturization and intelligent control design. Copyright © 2012 John Wiley & Sons, Ltd.

The integrity of the medical literature about robotic surgery remains unclear despite wide-spread adoption. We sought to determine if payment from Intuitive Surgical Incorporated (ISI) affected quality of the research produced by surgeons.

A 66-year-old woman was referred to our institute for an enlarging tumor of the thyroid, and neck and chest computed tomography scan showed not only a thyroid tumor, but also an anterior mediastinal tumor and ground-glass nodules in the lung. Because of persisting symptoms, an enlarging thyroid mass, and the possibility of cancer, excision of the tumors was proposed. A 6-cm-long vertical skin incision was made in the right axilla, a mini-thoracotomy was made in the third intercostal space, and an additional port was placed in the fifth intercostal space. Thoracoscopic partial resection of the right upper lobe of the lung was performed first. Then, the da Vinci surgical system (da Vinci, Intuitive Surgical Inc., Sunnyvale, CA, USA) was introduced through the mini-thoracotomy. The mediastinal tumor was then excised circumferentially robotically. After resection of the lung and mediastinal tumors, the da Vinci was undocked, and a subcutaneous tunnel from the axillary incision to the thyroid was created using the flap dissection technique. The da Vinci was re-introduced through the axillary incision. A long camera port was used, and the skin and muscle flap was elevated to maintain adequate working space during the robot-assisted thyroidectomy. Total operating time was 277 min, and the patient’s postoperative course was uneventful. The histopathological examinations of the lung, mediastinal, and thyroid tumors were adenocarcinoma, thymolipoma, and adenomatous goiter, respectively. In conclusion, single-incision robotic surgery for three lesions was achieved safely with good clinical results and excellent cosmetic results.

Renal artery aneurysm (RAA) is rare and its incidence in the general population remains elusive. There have been few reports on the repair of multiple aneurysms conducted with the Da Vinci robot-assisted surgical platform (Intuitive Surgical Inc., Sunnyvale, CA, USA), especially for those located in renal artery primary bifurcations.

Multiport laparoscopy is the gold-standard approach for cholecystectomy, and single-port laparoscopy has been developed to further reduce its invasiveness. A specific robotic single-port platform (da Vinci single-site, Intuitive Surgical Inc., Sunnyvale, CA, USA) has been released in 2011, which could technically facilitate single-site cholecystectomy. Current data show its feasibility; however, detailed short- and long-term analyses of costs and comparisons relative to multiport laparoscopy are not available to date.

The aim of this study was to describe the early results of a phase 1 safety and feasibility clinical trial of the first clinical use of a novel robot for transoral robotic surgery (TORS)-the da Vinci SP (Intuitive Surgical Inc., Sunnyvale, CA, USA). Study design of this study is prospective clinical trial. The methods used in this study are prospective innovation, development, exploration, assessment, and long-term study phase 1 clinical trial. Early results of six patients underwent TORS with the da Vinci SP (Intuitive Surgical Inc., Sunnyvale, CA, USA) demonstrate access the nasopharynx, oropharynx, larynx, and hypopharynx. There were no conversions of the robotic surgical system. There were no serious adverse events or adverse events related to the use of the robot at 30-day follow-up for all six patients. The early results of this safety and feasibility trial of the da Vinci SP (Intuitive Surgical Inc., Sunnyvale, CA, USA) clearly demonstrate that the device is safe and that it is feasible in performing TORS to access the nasopharynx, oropharynx, larynx, and hypopharynx.

Various surgical techniques have been described for the treatment of rectocele[1].Ventral mesh rectopexy is one of the surgical techniques for the treatment of pelvic floor diseases. This approach could be performed laparoscopically or robotically[1,2]. Robotic (da Vinci Surgical System, Intuitive Surgical, Sunnyvale, CA, USA) platform has several benefits compared to the laparoscopic approach such as stable retraction and enhanced dexterity[3,4].

The da Vinci Xi Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA) has been released in 2014 to facilitate minimally invasive surgery. Novel features are targeted towards facilitating complex multi-quadrant procedures, but data is scarce so far. Perioperative data of patients who underwent robotic general surgery with the da Vinci Xi system within the first 6 month after installation were collected and analyzed. The gastric bypass procedures performed with the da Vinci Xi Surgical System were compared to an equal amount of the last procedures with the da Vinci Si Surgical System. Thirty-one foregut (28 Roux-en-Y gastric bypasses), 6 colorectal procedures and 1 revisional biliary procedure were performed. The mean operating room (OR) time was 221.8 (±69.0) minutes for gastric bypasses and 306.5 (±48.8) for colorectal procedures with mean docking time of 9.4 (±3.8) minutes. The gastric bypass procedure was transitioned from a hybrid to a fully robotic approach. In comparison to the last 28 gastric bypass procedures performed with the da Vinci Si Surgical System, the OR time was comparable (226.9 versus 230.6 min, p = 0.8094), but the docking time significantly longer with the da Vinci Xi Surgical System (8.5 versus 6.1 min, p = 0.0415). All colorectal procedures were performed with a single robotic docking. No intraoperative and two postoperative complications occurred. The da Vinci Xi might facilitate single-setups of totally robotic gastric bypass and colorectal surgeries. However, further comparable research is needed to clearly determine the significance of this latest version of the da Vinci Surgical System.

The da Vinci system (da Vinci Surgical System; Intuitive Surgical Inc.) has rapidly developed in several years from the S system to the Si system and now the Xi System. To investigate the surgical feasibility and to provide workflow guidance for the newly released system, we used the new da Vinci Xi system for transoral robotic surgery (TORS) on a cadaveric specimen. Bilateral supraglottic partial laryngectomy, hypopharyngectomy, lateral oropharyngectomy, and base of the tongue resection were serially performed in search of the optimal procedures with the new system. The new surgical robotic system has been upgraded in all respects. The telescope and camera were incorporated into one system, with a digital end-mounted camera. Overhead boom rotation allows multiquadrant access without axis limitation, the arms are now thinner and longer with grabbing movements for easy adjustments. The patient clearance button dramatically reduces external collisions. The new surgical robotic system has been optimized for improved anatomic access, with better-equipped appurtenances. This cadaveric study of TORS offers guidance on the best protocol for surgical workflow with the new Xi system leading to improvements in the functional results of TORS.

Our video shows our technique of robotic restorative proctocoloectomy in a patient with ulcerative colitis. The operation is performed via a medial-to-lateral approach through seven ports. The robot (da Vinci Xi System, Intuitive Surgical Inc., Sunnyvale, CA, USA) is docked from the patient’s right side. First, the ileocolic vessels are isolated, clipped, and divided. Staying between the embryological planes anterior to the retroperitoneal structures, mesenteric dissection is continued up to the root of the middle colic vessels, which are transected between clips.
