Minimally Invasive Myxoma Resection: A Single-Center 5 Years' Experience.

BACKGROUND There is an increasing demand for minimally invasive myxoma resection. This study aimed to investigate the safety and feasibility of minimally invasive myxoma resection. METHODS In this retrospective study, we collected information from 95 patients who underwent myxoma resection between January 2016 and December 2020. Based on the operative approach, the patients were divided into the minimally invasive myxoma resection (Mini-MR) group (N = 30) and the sternotomy myxoma resection (SMR) group (N = 65). Intraoperative and postoperative data were compared between the two groups. RESULTS The postoperative ventilator-assisted time, CSICU time, and postoperative hospital stay were shorter in the Mini-MR group than in the SMR (13.05 ± 4.98 vs. 17.07 ± 9.52 h; 1.73 ± 0.29 vs. 2.27 ± 1.53 d; 6.20 ± 1.50 vs. 9.48 ± 3.37 d, respectively), and the difference was statistically significant (P < 0.05). Mini-MR had lower postoperative drainage and blood transfusion rate in the first 24 h compared with SMR (38.93 ± 69.62 vs. 178.25 ± 153.06 ml; 26.6% vs. 63.1%), and the differences were statistically significant (P < 0.05). CONCLUSION Mini-MR has the advantages of less CSICU stay time, less ventilator time, less postoperative drainage in the first 24h, less blood transfusion, fewer postoperative hospital stays, and faster recovery. Mini-MR is a safe and feasible surgical procedure for myxoma resection.
