Abstract： Objective To compare clinical outcomes of complete video-assisted thoracoscopic surgery （cVATS） lobectomy with routine thoracotomy lobectomy for the treatment of bronchiectasis, and evaluate the feasibility, safety and specific considerations of cVATS lobectomy for the treatment of bronchiectasis. Methods We retrospectively analyzed the clinical data of 115 patients who underwent lobectomy for the treatment of bronchiectasis in Beijing Chaoyang Hospital from May 2009 to January 2012. According to the way of operation, these patients were divided into two groups （cVATS group and thoracotomy group）. In the thoracotomy group, there were 62 patients （28 males and 34 females with an age of 46.2±11.9 years） who underwent routine thoracotomy lobectomy. In the cVATS group, there were 53 patients （19 males and 34 females with an age of 45.7±12.2 years） who underwent cVATS lobectomy. Operation time, intra-operative blood loss, postoperative thoracic drainage, complications and hospitalization, and cost of hospitalization were compared between the two groups. Results There was no perioperative death in all patients. There was no statistical difference in operation time between the two groups. Intra-operative blood loss of thoracotomy group patients was significantly higher than that of cVATS group patients （228.8±121.7 ml vs. 157.1±123.8 ml, t=2.592, P=0.011）. Postoperative thoracic drainage （866.7±439.5 ml vs. 1 805.3±466.7 ml, t=9.003，P=0.000）, duration of chest tube drainage （6.6±3.3 d vs. 9.8±4.6 d,t=3.339，P=0.001）, and postoperative hospitalization （7.5±2.2 d vs. 11.2±5.4 d, t=3.424，P=0.001） of cVATS group were significantly lower than those of thoracotomy group. The cost of hospitalization of cVATS group was significantly higher than that of thoracotomy group （38 543.6±11 051.8 yuan vs. 30 523.4±10 028.5 yuan，t=3.423, P=0.001）. There was no statistical difference in postoperative complications between the two groups （P＞0.05）. Forty-five patients in cVATS group were followed up for 2 to 14 months. Among them, 42 patients completely had no sputum or haemoptysis and 3 patients still intermittently had some sputum. Conclusion cVATS lobectomy is safe and feasible for the treatment of bronchiectasis. Compared with routine thoracotomy lobectomy, cVATS lobectomy does not increase surgical risk, but can significantly reduce operation injury and length of hospital stay. During cVATS, the lung residual should be handled cautiously especially for patients with nonanatomic pulmonary resection, and the non-single-order operation is recommended.
Abstract： Objective To find out goodness and weakness by comparing totally thoracoscopic surgery （TTS）and median sternotomy （MS）with cardiopulmonary bypass for pediatric open heart operation. Methods One hundred and fortyseven patients with ventricular septal defect(VSD) and atrial septal defect(ASD) were randomly divided into two groups according to operative methods, TTS group: patients were operated by totally thoracoscopy; MS group: patients were operated by median sternotomy with cardiopulmonary bypass. The clinical records from two groups were compared on operative effect, complications, hospitalization, ventilation time,variations of main data of blood routine test, drainage of pleura cavity, blood loss and transfusion, and pulmonary function. Results There were no death in two groups. There was VSD residual leak the same day after operation which was cured by TTS in one patient of TTS group. There was one case which bleeding was stopped by second operation in MS group. Followup visit were made to 41 patients for 3 months, no heart murmur was detected. The ultrasonic cardiography (UCG) showed that correcting of VSD and ASD were good and had no residual leak. The hospitalization,aortic clampping time, ventilation time and variations of main data of blood routine test, drainage of pleura cavity, blood transfusion and blood loss in TTS group had no significant difference to those in MS group (Pgt;0.05). Operating times was longer in TTS group than that in MS group, while stays in the intensive care unit were shorter in TTS group than that in MS group (Plt;0.01). Preoperative and 3 months postoperative pulmonary function of both teams had no statistically significant difference in two groups (Pgt;0.05). Conclusion TTS is a safe and effective method to pediatric VSD and ASD as MS is.
ObjectiveTo examine the differences between totally thoracoscopic surgery and median sternotomy in scope of trauma, postoperative recovery and postoperative complications. MethodsWe retrospectively analyzed the clinical data of 331 patients with cardiac myxoma in our hospital between January 2001 and November 2015. The patients were devided into 2 groups by the different methods of operation:a totally thoracoscopic surgery group including 196 patients with 71 males and 125 females at a mean age of 50 (42.00-57.50) years, and a median sternotomy group including 135 patients, with 53 males and 82 females at a mean age of 52 (38.00-61.00) years. The clinical records of the two groups were compared in scope of trauma, postoperative recovery, and postoperative complications. ResultsThere was shorter time in breathing machine and ICU time (P<0.001), and fewer volume in blood transfusion, blood loss (P<0.001) in the totally thoracoscopic surgery group. There was less pain and postoperative complications (P<0.001) in the totally thoracoscopic surgery group. The aortic clamp time in the totally thoracoscopic surgery group was not significantly different compared with that in the median sternotomy group (P=0.15) While cardiopulmonary bypass time was shorter in the median sternotomy group (P<0.001). ConclusionTotally thoracoscopic surgery is a safe and reliable method in treating cardiac myxoma. Our results suggest that totally thoracoscopic surgery has the advantage of fewer blood loss, blood transfusion, and postoperative complications compared with median sternotomy surgery. Totally thoracoscopic surgery leads to earlier recovery and less pain.
Objective To evaluate the outcomes and summarize the clinical experience of totally endoscopic mitral valve repair with artificial chordae implantation. Methods From May 2013 to June 2016, 71 patients with mitral valve insufficiency were admitted to our hospital who underwent totally endoscopic mitral valve repair with artificial chordae implantation. There were 47 males and 24 females with the age of 46.0±14.4 years ranging from 13-78 years. The pathogenesis included degenerative valvular diseases in 63 patients, congenital valvular diseases in 4, infectious endocarditis in 2, rheumatic disease in 1 and cardiomyopathy in 1. Prolapse of anterior, posterior, or both leaflets was present in 26 (36.6%), 19 (26.8%), and 25 (35.2%) patients, respectively; one patient (1.4%) presented valve annulus enlargement and thirteen were associated with commissure lesion. The mitral regurgitation area ranged from 4.2 to 26.3 cm2 (mean, 12.2±5.6 cm2). All the procedures were performed by total endoscopy under cardiac arrest. 5-0 Gore-tex sutures were used as the material of artificial chordae which was implanted one by one. Results There was no in-hospital death. One patient was transferred to mitral valve replacement, and one median sternotomy due to bleeding. The mean cardiopulmonary bypass time was 156.0±31.6 min and aortic cross-clamp time 110.0±20.1 min. We finally had 39 isolated mitral valve repair, 28 mitral valve repair combined tricuspid valve repair, 3 mitral valve repair combined atrial septal defect closure, and 1 mitral valve repair combined correction of partial anomalous pulmonary vein connection. Each patient was implanted artificial chordae of 2.5±1.7 (ranging from 1 to 7), and 65 patients received mitral annulus (full ring). The intraoperative transoesophageal echocardiography found no mitral regurgitation in 44 patients, the area of mitral regurgitation was 0-2 cm2 in 24, and 3 patients with mitral regurgitation>2 cm2 experienced serious systolic anterior motion. Of the 3 patients with systolic anterior motion (SAM), one transferred to mitral valve replacement, one underwent mitral re-repair, and one took conservative treatment. The mean follow-up was 12.7±10.5 months (range: 1 to 36 months), while 2 patients were lost to follow up with the follow-up rate of 97.2%. Recurrent severe regurgitation occured in 3 patients, moderate in 5, mild or trivial in 27 and no regurgitation in 36. During the follow-up, 1 patient died of myocardiopathy-induced heart failure post discharge, 1 suffered from cerebral infarction, and no patient underwent reoperation. Conclusion The totally endoscopic surgical treatment of mitral valvuloplasty with artificial chordae is reliable for patients with mitral valve prolapse, which provides favorable clinical efficacy and outcomes. The difficulty lies in how to determine the appropriate length of the chordae and keep the stability of length.
ObjectiveTo investigate the feasibility, safety and effectiveness of radiofrequency ablation of atrial fibrillation with mitral valve replacement under totally thoracoscopic surgery.MethodsThe clinical data of 107 patients with rheumatic mitral disease and atrial fibrillation who underwent mitral valve replacement and radiofrequency ablation at the same time in our hospital from January 2014 to October 2018 were retrospectively analyzed. The patients were divided into two groups: a totally thoracoscopic surgery group (n=51, including 20 males and 31 females, aged 50.57±5.24 years) and a median sternotomy group (n=56, including 21 males and 35 females, aged 52.12±5.59 years) according to the surgical methods. The preoperative, intraoperative and postoperative data of the patients were compared.ResultsAll operations were successfully completed without death. In terms of bleeding volume, drainage volume, ventilator-assisted breathing time, hospital stay and incision length, the totally thoracoscopic surgery group was better than the median sternotomy group, and the difference was statistically significant (P<0.05). The cardiopulmonary bypass time and radiofrequency ablation time in the totally thoracoscopic surgery group were longer than those in the median sternotomy group (P<0.05). There was no significant difference in the operation time, aortic occlusion time, postoperative complications, left ventricular ejection fraction, left atrial diameter and sinus rhythm maintenance between the two groups (P>0.05). There was no atrioventricular block, pulmonary vein stenosis, atrioesophageal fistula, coronary artery injury, stroke or hemorrhage during the follow-up.ConclusionRadiofrequency ablation of atrial fibrillation with mitral valve replacement under totally thoracoscopic surgery is safe and effective, and it is worthy of clinical application.
ObjectiveTo evaluate the early and mid-term outcomes of total thoracoscopic Box Lesion radiofrequency ablation in patients with atrial fibrillation.MethodsThe clinical data of 31 patients with atrial fibrillation who underwent total thoracoscopic Box Lesion radiofrequency ablation between November 2011 and March 2018 at the Department of Cardiac Surgery in our hospital were retrospectively analyzed, including 23 males and 8 females at an average age of 66.17±8.32 years. All patients did not have concomitant severe organic heart disease which required surgical intervention.ResultsThere were 20 patients with paroxysmal atrial fibrillation, 8 with persistent atrial fibrillation, and 3 with long-standing persistent atrial fibrillation. Twenty-nine patients got the 3-year follow-up, and 2 patients were lost to the follow-up 6 months after the surgery. The procedure was successfully performed in all patients, with an average operation time of 113.00±26.00 min. There was no perioperative death or related complication. All patients were restored to sinus rhythm immediately after surgery. Five patients got atrial fibrillation during postoperative hospitalization, which reverted to sinus rhythm after electrical cardioversion. The rate of sinus rhythm maintenance was 62.9%, 55.9% and 52.4% in postoperative 1, 2 and 3 years, respectively. No patient died during the period, and no procedure-related complication was observed.ConclusionTotal thoracoscopic Box Lesion radiofrequency ablation effectively shortens operation time, and reduces surgical trauma and procedure-related complications, meanwhile, ensures the surgical outcomes.
