Comparison between noninvasive and conventional skin closure methods in off-pump coronary artery bypass grafting using bilateral internal thoracic artery

Sternal wound complications could increase the hospital cost while decreasing the satisfaction of surgery. Furthermore, it can potentially also lead to life-threatening mediastinitis especially after coronary artery bypass grafting using bilateral internal thoracic artery (BITA). Skill levels of suture technique vary among surgeons and may contribute to an increased wound complication rate. Thus, standardization of surgical wound closure could potentially decrease the surgeon factor. The aim of the study is to compare the wound complication rate between non-invasive surgical skin closure devices (zip surgical skin closure device, Zipline Medical, Campbell, CA, USA) and conventional suture closure.
