Endo-robotic resection of the submandibular gland in a cadaver model,

HEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 11 2005
David J. Terris MD
Abstract Background. By means of a prospective, nonrandomized investigation, we evaluated the feasibility of performing endo-robotic resection of the submandibular gland in a cadaver model and compared the results of robotically enhanced endoscopic surgery with those from a conventional endoscopic technique. Methods. Procedural times were recorded in a consecutive series of 11 endoscopic submandibular gland resections using the daVinci Surgical System (Intuitive Surgical, Sunnyvale, CA) and a modified endoscopic surgical approach previously developed in a porcine model. The presence of neurovascular injury was assessed postoperatively, and the specimens were examined histologically. Results. Eleven endo-robotic submandibular gland resections were successfully performed in six cadavers (no conversions to open resection were necessary). The median duration of the procedures was 48 minutes (range, 33,82 minutes). Creation of the operative pocket took an average (±SD) of 12.2 ± 5.3 minutes, assembly of the robot required 9.3 ± 4.1 minutes, and the mean time for submandibular gland resection was 29.4 ± 8.9 minutes. The time required for robotic assembly was offset by the reduced operative time necessary compared with conventional endoscopic resection. Histologic examination confirmed the presence of normal glandular architecture, without evidence of excessive mechanical or thermal injury. There were no cases of apparent neurovascular injury. Conclusions. Robotically enhanced endoscopic surgery in the neck is feasible and offers a number of compelling advantages over conventional endoscopic neck surgery. Clinical trials will be necessary to determine whether these advantages can be achieved in clinical practice. © 2005 Wiley Periodicals, Inc. Head Neck27: XXX,XXX, 2005 [source]

Robotics in cardiac surgery: the Istanbul experience

THE INTERNATIONAL JOURNAL OF MEDICAL ROBOTICS AND COMPUTER ASSISTED SURGERY, Issue 2 2006
Ertan Sagbas
Abstract Background Robots are sensor-based tools capable of performing precise, accurate and versatile actions. Initially designed to spare humans from risky tasks, robots have progressed into revolutionary tools for surgeons. Tele-operated robots, such as the da VinciÔ (Intuitive Surgical, Mountain View, CA), have allowed cardiac procedures to start benefiting from robotics as an enhancement to traditional minimally invasive surgery. Methods The aim of this text was to discuss our experience with the da Vinci system during a 12 month period in which 61 cardiac patients were operated on. There were 59 coronary bypass patients (CABG) and two atrial septal defect (ASD) closures. Results Two patients (3.3%) had to be converted to median sternotomy because of pleural adhesions. There were no procedure- or device-related complications. Conclusion Our experience suggests that robotics can be integrated into routine cardiac surgical practice. Systematic training, team dedication and proper patient selection are important factors that determine the success of a robotic surgery programme. Copyright © 2006 John Wiley & Sons, Ltd. [source]

Transoral Robotic Surgery: Supraglottic Laryngectomy in a Canine Model,

THE LARYNGOSCOPE, Issue 7 2005
Gregory S. Weinstein MD
Abstract Objectives/Hypothesis: To develop a technique for computer enhanced robotic transoral supraglottic partial laryngectomy in the canine model. Study Design: Surgical procedure on the larynx in a canine model with a commercially available surgical robot. Methods: With use of the da Vinci Surgical Robot (Intuitive Surgical, Inc., Sunnyvale, CA), the supraglottic partial laryngectomy was performed on a mongrel dog that had been orotracheally intubated using general anesthesia. The videoscope and the 8 mm end-effectors of the robotic system were introduced through three ports, transorally. The surgical procedure was performed remotely from the robotic system console. The procedure was documented with still and video photography. Results: Supraglottic partial laryngectomy was successfully performed using the da Vinci Surgical Robot, with 8 mm instrumentation. The robotic system allowed for celerity and accuracy secondary to findings specific to the surgical approach, including excellent hemostasis, superb visualization of the operative field with expeditious identification of laryngeal submucosal soft tissue and skeletal landmarks, and multiplanar transection of tissues. In addition, the use of the robotic system also was found to have technical advantages inherent in robotic surgery, including the use of "wristed" instrumentation, tremor abolition, motion scaling, and three-dimensional vision. Conclusions: The da Vinci Surgical Robot allowed for successful robotic transoral supraglottic partial laryngectomy in the canine model. [source]

Robotic Skeletonized Internal Thoracic Artery Harvesting: The Sliding Fascia Technique

ARTIFICIAL ORGANS, Issue 6 2010
Norihiko Ishikawa
Abstract Robotic skeletonizing and harvesting of the internal thoracic artery, using the da Vinci surgical system, has a number of advantages over robotic pediculed ITA harvesting. The advantages include greater blood flow, a longer conduit, and less bleeding. The technique is facilitated by use of the EndoWrist spatula cautery and fine tissue forceps (Intuitive Surgical, Inc., Sunnyvale, CA, USA). How the technique is performed is described in this report. [source]

Robot-assisted laparoscopic adrenalectomy: preliminary UK results

BJU INTERNATIONAL, Issue 3 2004
S. Undre
Authors from London describe the early results from the UK in the use of robot-assisted laparoscopic adrenalectomy. In a small group of patients they found that patients could be treated early, with early discharge from hospital. The use of retrograde balloon dilatation of PUJ obstruction is revisited by authors from Plymouth, who review their 10 years of experience with this technique. They found that the procedure gave good symptomatic relief in 76% of their patients, but found no relationship between symptom relief and renographic improvement. In a few patients with a long-term follow-up there was symptomatic improvement and good maintenance of split renal function. OBJECTIVE To describe the results of our first two cases of laparoscopic adrenalectomy using the da VinciTM surgical system (Intuitive Surgical, Inc., Mountain View, CA, USA). PATIENTS AND METHODS Amongst 75 robot-assisted procedures performed at our institution, two patients underwent robot-assisted laparoscopic adrenalectomy. The set-up time, procedure time, hospital stay, complications and outcomes were recorded. RESULTS Both operations were completed successfully using the robot; the mean (range) set-up time was 31 (25,37) min and mean procedure time 118.5 (107,130) min. One patient had a postoperative pulmonary embolus and was discharged 5 days after surgery; the second patient was discharged after 3 days. There were no intraoperative complications; both patients were well at the 1-year follow-up CONCLUSIONS Robot-assisted laparoscopic adrenalectomy is technically feasible and can be conducted efficiently and safely with the da Vinci surgical system.
