Learning Curve for No-Touch Vein Harvesting Technique in Off-Pump Coronary Artery Bypass Grafting.
INTRODUCTION
This study aims to evaluate the learning curve associated with the no-touch vein harvesting technique in off-pump coronary artery bypass grafting (CABG), highlighting its impact on surgical proficiency.
METHODS
We employed logarithmic curve fitting to analyze the learning curves of 160 patients undergoing no-touch CABG, with a detailed retrospective examination of 89 patients who received three grafts using Cumulative Sum (CUSUM) analysis. Patients were categorized into two phases: the initial learning phase and the subsequent mastery phase, based on the chronological order of surgeries. We then compared perioperative outcomes between these phases.
RESULTS
The learning curve for the no-touch vein harvesting technique was quantitatively established at 51 cases via CUSUM analysis, with supporting evidence from logarithmic curve fitting indicating a significant proficiency milestone. In the mastery phase, median operative times, aorta-saphenous vein graft (SVG) anastomosis, and SVG inspection durations were notably reduced (230 vs. 250 minutes, P = 0.002; 11.5 vs. 13.0 minutes, P = 0.025; 9.0 vs. 11.0 minutes, P = 0.002, respectively), alongside decreased initial 48-hour chest tube drainage, shorter postoperative hospital stays, and fewer incidences of delayed leg incision healing compared to the learning phase [312.6 (140.7) ml vs. 401.0 (233.5) ml, P = 0.029; 11.0 d vs. 12.0 d, P = 0.026; 15.7% vs. 2.6%, P = 0.043)].
CONCLUSION
Cardiac surgeons adopting the full-incision SVG harvesting method for no-touch CABG undergo a discernible learning curve before achieving early proficiency. It is crucial, especially during the initial learning phase, to focus on aorta-SVG anastomosis, the meticulous inspection for bleeding, and the management of wound complications to optimize patient outcomes.
期刊介绍:
''Cardiology'' features first reports on original clinical, preclinical and fundamental research as well as ''Novel Insights from Clinical Experience'' and topical comprehensive reviews in selected areas of cardiovascular disease. ''Editorial Comments'' provide a critical but positive evaluation of a recent article. Papers not only describe but offer critical appraisals of new developments in non-invasive and invasive diagnostic methods and in pharmacologic, nutritional and mechanical/surgical therapies. Readers are thus kept informed of current strategies in the prevention, recognition and treatment of heart disease. Special sections in a variety of subspecialty areas reinforce the journal''s value as a complete record of recent progress for all cardiologists, internists, cardiac surgeons, clinical physiologists, pharmacologists and professionals in other areas of medicine interested in current activity in cardiovascular diseases.
