[Clinical outcomes of totally endoscopic coronary artery bypass grafting: a system review and meta-analysis]

Objective: To assess the clinical outcomes of totally endoscopic coronary artery bypass grafting (TECABG). Methods: A systematic review of studies reporting clinical outcomes of TECABG was performed. Twelve studies were included in the meta-analysis. R 3.2.3 was used to perform the statistical analysis. Results: Length of hospital stay of TACABG patients ranged from 3.3 to 8.6 days. The rate of recent conversion to thoracotomy was 0-28.1% (from perioperative period to 2 years after surgery); the rate of anastomotic bleeding was 1.7%-8.5%; the case fatality rate of in-hospital or 30 days after surgery was 0-3.8%; the rate of myocardial infarction was 0-3.4%; the rate of stroke was 0-2.2%; the rate of revascularization was 0-6.8%; the patency rate of recent coronary artery bypass graft (CABG) was 89.5%-100%; the mid-time survival rate of TECABG patients (from 2 to 5 years after surgery) was 92.7%-100%; the rate of revascularization was 2.0%-12.2%; the patency rate of mid-time CABG was 71.4%-97.0%. Conclusions: The current data suggests that TECABG is feasible, safe and effective when proper patients are selected. However, randomized controlled trials of TECABG versus conventional CABG are still required due to lack of long-term outcomes.
