英文摘要

Background: The learning curve for off-pump coronary artery bypass grafting (OPCABG) surgery still requires further discussion. Training programs aimed at the conversion of conventional coronary artery bypass grafting (CABG) to OPCABG have mainly been geared towards those persons who already have much experience in conventional CABG. The goals of this study were to retrospectively analyze the training process of two trainees who had no previous coronary surgery experience and to discuss the efficiency and feasibility of the training.

Methods: Two cardiac surgeons were enrolled in this study; they had different surgical backgrounds but neither had ever previously performed coronary surgery. They were trained to become independent surgeons capable of performing OPCABG procedures by a supervising surgeon who had performed more than 2000 OPCABG surgeries. Clinical data were collected from each trainee subject′s first 100 cases of OPCABG surgery and grouped according to the following scheme: Group A(1) (Doctor A′s first 50 cases), Group A(2) (Doctor A′s second 50 cases), Group B(1) (Doctor B′s first 50 cases) and Group B(2) (Doctor B′s second 50 cases). A consecutive series of 50 cases of OPCABG surgery performed by the supervising surgeon served as the control group (Group C). Cumulative sum failure analysis for each subject was used to complete the learning curve study.

Results: The training time was 28 months for Doctor A and 24 months for Doctor B; the difference in training time was presumably due to their different surgical backgrounds. Among the cases in Group A(1), Group A(2) and Group B(1), there were fewer distal anastamoses, fewer sequential grafts, and less marginal branch grafting in the left circumflex artery than in the Group C cases. Operating times and ICU stay were longer in Group A(1) than in Group C. There were no group differences with regard to total mortality or the incidence of complications. CUSUM analysis showed that the curves of the two trainees had a small steep elevation during the first 30 cases, and proceeded smoothly thereafter, never passing the 80% alert lines.

Conclusions: The appropriate qualifications for OPCABG trainees and the optimal OPCABG training program have not yet been resolved. In this study, the observed learning curves of cardiac surgeons who had no prior coronary Surgery experience during their training to perform the OPCABG procedure by a sophisticated OPCABG surgeon indicated that the training program employed was feasible and its outcomes were reasonable.
