OBJECTIVES: Endoscopically sutured vascular anastomoses are complex, time consuming, and require great dexterity. We decided to evaluate performance enhancement using a robotic device to create sutured coronary artery bypass anastomoses with endoscopic techniques in a plastic model. METHODS: Seven coronary artery bypass anastomoses were endoscopically created in a plastic model using a robotic enhancement technology (Computer Motion, Goleta, CA). Anastomoses were created with a single running suture (7-0 monofilament). Our endpoints were operative time, intraoperative incidents, stability and dexterity of the robotic system, surgeon's fatigue, and anastomotic patency. RESULTS: Operative time was 46+/-12 min (mean+/-SD). There were no intraoperative incidents. Patency was confirmed in all anastomoses. The system's stability and dexterity were high. Surgeon's fatigue was mild. CONCLUSION: The use of robotic enhancement technology leads to an efficient performance of sutured coronary artery bypass anastomoses in a plastic model. The robotic device enhances dexterity, precision, and reduces surgeon's fatigue while preserving the quality of hand suturing.
