| Objective: At present,mitral valvuloplasty is the most important operation for the treatment of mitral insufficiency.With the application of minimally invasive technology in the field of heart,various institutions participate in learning,but the results are different.This study summarized the experience and results of minimally invasive small incision mitral valvuloplasty under thoracoscopy in the First Affiliated Hospital of Guangxi Medical University.Through retrospective analysis,the small incision mitral valvuloplasty and the median incision mitral valvuloplasty were compared to evaluate the efficacy of hand surgery.Methods: From January 2017 to December 2019,49 patients in cardiac surgery of the First Affiliated Hospital of Guangxi Medical University were selected.Among them,23 patients underwent thoracoscopic minimally invasive mitral valvuloplasty,and the other 26 patients underwent median incision mitral valvuloplasty.The patients were divided into minimally invasive group and traditional group for retrospective analysis.We collected all kinds of information and data of patients,as well as the results and complications related to the operation.We selected the minimally invasive group as the observation group and compared it with the traditional group.Results: There was no significant difference in gender,blood pressure,age,heart rate,NYHA cardiac function grade and cardiac function index between the minimally invasive group and the traditional group.There were significant differences between the two groups in the time of cardiopulmonary bypass,the length of ventilator use,the time of aortic occlusion,and the average time of operation.Compared with the traditional group,the above indicators in the minimally invasive group were all significantly different from the traditional group.The other indicators,such as ICU observation time,postoperative hospital stay time,the total amount of blood products used,and the total postoperative induced flow,were significantly different between the two groups.The minimally invasive group was less than the traditional group.There was no significant difference between the two groups before the complications.The number of columns in the pain grade minimally invasive group was significantly lower than that in the traditional group.The minimally invasive group was divided into three groups according to the year.The average time of operation and the total amount of postoperative bleeding in the minimally invasive group decreased significantly in 2019 compared with that in 2017,which was statistically significant,while the cardiopulmonary bypass time and aortic occlusion time in 2019 compared with that in 2017 were slightly reduced,but there was no statistical significance.Conclusions: 1.Minimally invasive mitral valvuloplasty under thoracoscopy has the advantages of safety and effectiveness.2.the mortality and complication rate of simultaneous interpreting of this operation were not significantly different from those of traditional median incision surgery.Although the operation should be extended on average,the postoperative effect was obviously better than that of traditional surgery.The patients had less bleeding after operation,quicker recovery,and better incision appearance,and greatly improved the quality of life of the patients.3.The operation is a complex and challenging new technology,with a long learning curve,which requires the tacit cooperation between the entire operation team to improve the operation efficiency and effect. |
