Abstract
OBJECTIVES
The aim of this study was to discuss the perioperative effects of obesity on minimally invasive coronary artery bypass grafting (CABG) and its surgical techniques.
METHODS
A total of 582 patients with multivessel lesion who underwent off-pump CABG by our medical group of Beijing Anzhen Hospital between January 2017 and January 2021 were divided into the minimally invasive cardiac surgery (MICS) group and the conventional group (median sternotomy) according to the surgical method used. The body mass index of the patients was calculated, based on which both groups were divided into obese (≥28 kg/m2) and non-obese subgroups (<28 kg/m2). First, the perioperative data of the obese subgroups of both MICS and conventional groups were compared. Second, the obese and non-obese subgroups were compared in the MICS group.
RESULTS
Despite a higher proportion of diabetes in the MICS group, there was no significant difference in preoperative baseline nor in the incidence of major complications within 30 days after surgery between obese subgroups of the MICS and conventional groups. The MICS group had a significantly lower rate of poor wound healing, along with a higher predischarge Barthel Index. Also, the preoperative baseline between the obese and non-obese subgroups of the MICS group exhibited no statistical differences. The obese subgroup had longer postoperative ventilator assistance, while other intraoperative data and postoperative observation indexes exhibited no significant differences.
CONCLUSIONS
MICS CABG method is safe and feasible for obese patients with multivessel lesion. Minimally invasive surgery is beneficial to wound healing in obese patients. However, it requires a thorough preoperative evaluation and adequate surgical experience and skills.
