How to improve performance of robotic totally endoscopic coronary artery bypass grafting

BackgroundWe investigated whether specific surgical measures during the learning curve can influence procedural performance in robotic totally endoscopic coronary artery bypass grafting (TECAB).MethodsFrom 2001 to 2006, 70 patients underwent TECAB using the da Vinci telemanipulation system (Intuitive Surgical, Sunnyvale, CA). The following measures were employed with the intent to improve procedure performance: (1) introduction of a fixed team of surgeons at case 14; (2) application of fibrin glue to seal the anastomosis at case 28; and (3) use of a fourth port for transthoracic assistance at case 49.ResultsAll 3 measures resulted in a reduction of operating room (OR) time (27%, 20%, and 20%). Use of a stable OR team and peri-anastomotic fibrin glue reduced the rate of conversions and on-table revisions from 39% to 9% (P = .006) and from 26% to 7% (P = .038), respectively. Peri-anastomotic fibrin glue significantly reduced postoperative revisions for bleeding. Using transthoracic assistance, anastomotic time was shortened from 35 minutes (range 23–67) to 25 minutes (range 16–100) (P < .001).ConclusionThe 3 measures can improve intraoperative and clinical results in TECAB.
