Magnetic anchoring and traction technique is one of the core technologies of magnetic surgery. With the "non-contact" traction force of the outer magnet on the inner magnet, we can drive the inner magnet and the gripper to multiple directions, and pull tissue or organ to required position in operations, so as to get a clearer surgical field of view. On the basis of the previous animal experiments, we applied magnetic anchoring and traction device in 3 human (males aged 63-71 years) thoracoscopic esophagectomies. Using the magnetic anchoring device, we could pull the esophagus dorsally or ventrally to assist in exposing the anatomical plane without special equipment or pleural puncture for retraction of the esophagus. The interference between operating instruments reduced. The mean blood loss in operation was 83 mL, the mean total operation time was 253 min and the mean length of hospital stay was 10 d. Postoperative follow-up showed that all 3 patients had good short-term prognosis. There was no swellling or pain in magnetic anchoring zone of chest wall.
ObjectiveTo investigate the safety, feasibility and advantages of subxiphoid uni-portal thoracoscopic thymectomy.MethodsClinical data of 65 patients undergoing subxiphoid uni-portal thoracoscopic thymectomy in our hospital from September 2018 to March 2019 were retrospectively analyzed. They were treated as a subxiphoid surgery group, including 36 males and 29 females, aged 49.5 (29-71) years. The incision with the length of about 3 cm was located approximately 1 cm under the xiphoid process. From January 2016 to December 2017, 65 patients received intercostal uni-portal thoracoscopic thymectomy, who were treated as a control group, including 38 males and 27 females, aged 48.9 (33-67) years. All patients who were clinically diagnosed with thymic tumor before surgery were treated with total thymectomy. After surgery, expectoration and analgesia were used.ResultsThere was no statistically significant difference in general clinical data, lesion size, intraoperative blood loss, postoperative catheterization time, postoperative hospital stay and postoperative pathology between the two groups. All operations were successfully completed, and the patients in both groups recovered uneventfully after surgery. Visual analogue scale scores on the 1st, 3rd, 7th and 30th day after surgery in the subxiphoid surgery group were lower than those in the control group.ConclusionThe subxiphoid uni-portal thoracoscopic approach can achieve total thymectomy with less trauma and faster postoperative recovery.
ObjectiveTo increase the advantage and decrease the disadvantage of posterior approach for uniportal video-assisted thoracic surgery (VATS) right upper lobectomy.MethodsData of 97 consecutive patients who received uniportal VATS right upper lobectomy using posterior approach in the semiprone position were retrospectively analyzed from Dec, 2014 to Dec, 2017. There were 41 males and 56 females at age of 26–79 (57.8±10.6) years. The hilar structure was cut from posterior to anterior one by one. The mediastinal lymph nodes were dissected if lung cancer was diagnosed.ResultsNinety three of 97 patients were successfully completed with uniportal VATS right upper lobectomy using posterior approach, 3 of them were completed with posterior approach combined with anterior approach, and 1 of them needed thoracotomy. The mean operative time was 76–192 (127.0±32.0) min. The thoracic drainage time was 2–20 (3.4±2.7) d. The postoperative length of hospital stay was 3–23 (5.4±3.1) d. There were postoperative complications in 7 patients and no postoperative mortality.ConclusionPosterior approach for uniportal video-assisted thoracic surgery right upper lobectomy is safe and feasible, which can decrease the fatigue of both the surgeon and the assistant. It also provides with better exposure of posterior mediastinum, less dragging lung, and less interference of the instruments and help keep the clear surgical field. In complicated cases, posterior approach could combine with anterior approach to complete the VATS lobectomy.
Objective To investigate the security and feasibility of silk ligating for pulmonary artery in video-assisted thoracoscopic lobectomy, and to summarize the clinical skills. Methods We retrospectively analyzed the clinical data of 68 patients underwent the video-assisted thoracoscopic lobectomy from April 2013 to March 2015. There were 49 males and 19 females with the mean age of 59.6±10.3 years, ranging from 38 to 76 years. We divided the patients into an ECR60W cut-up group (31 patients) and a silk ligation group (37 patients). There were 22 males and 9 females patients with the average age of 59.3±9.9 years with ECR60W. There were 27 males and 10 females patients with the average age of 59.9±10.5 years with silk ligation. We observed the effect of hemostasis, and analyzed the amount of bleeding loss during operation, postoperative suction drainage and the cost of operation material between the two groups. Results There were 4 patients out of 68 converted to the open lobectomy, and all of them used ECR60W. The application of silk ligation for pulmo-nary artery could effectively control bleeding loss and avoid massive amount of bleeding due to the vascular tear in opera-tions. Furthermore, the application can reduce the rate of severe complications such as massive bleeding resulting from postoperative silk ligation slippage. There was a statistical difference between the two groups on the cost of operation mate-rials (P < 0.01). Conclusions Silk ligation for pulmonary artery in video-assisted thoracoscopic lobectomy is simple and prac-tical to apply. Compared with the ECR60W, it can significantly reduce the cost of operation material. It's worth to popularize in clinic.
ObjectiveTo explore an effective and safe drainage method, by comparing open thoracic drainage and conventional thoracic drainage for lung cancer patients after thoracoscopic pneumonectomy.MethodsThe clinical data of 147 patients who underwent thoracoscopic pneumonectomy from January 2015 to March 2018 in our hospital were retrospectively analyzed, including 128 males and 19 females. Based on drainage methods, they were divided into an open drainage group (open group) and a conventional drainage group (regular group). The incidence of postoperative complications, chest tube duration, drainage volume at postoperative 3 days, postoperative hospital stay, hospitalization cost and quality of life were compared between the two groups.ResultsPostoperative complication rate was lower in the open group than that in the regular group (10.20% vs. 23.47%, P=0.04). The chest tube duration of the open group was longer compared with the regular group (5.57±2.36 d vs. 3.22±1.23 d, P<0.001). The drainage volume at postoperative 3 days was less in the regular group. In the open group, ambulation was earlier, thoracocentesis was less and re-intubation rate was lower (all P<0.001). The postoperative hospital stay in the regular group was significantly longer than that in the open group (8.37±2.56 d vs. 6.35±1.87 d, P<0.001) and hospitalization cost was significantly higher (66.2±5.4 thousand yuan vs. 59.6±7.3 thousand yuan, P<0.001). Besides, quality of life in 1 and 3 months after operation was significantly better than that in the open group (P<0.001).ConclusionCompared with the regular chest drainage, the effect of open thoracic drainage is better, which can help reduce postoperative complications, shorten the length of hospital stay, reduce the hospitalization cost and improve the quality of postoperative life. It is worthy of clinical promotion.
Totally thoracoscopic surgery is a branch of minimally invasive cardiac surgeries, and its operational indicators are expanding with the development of the medical and imaging devices compared with median sternotomy and other minimally invasive cardiac surgeries (such as thoracoscope-assisted small incision surgery and robotic surgery). The learning curve is significantly shortened through the professional technique training. Totally thoracoscopic cardiac surgery has many advantages, such as minor trauma, few serious complications, fast recovery, high patient acceptance and being suitable to our country's current situation. Therefore it will be one main direction of minimally invasive cardiac surgery. This article mainly introduced the current status of totally thoracoscopic technology in the field of cardiac surgery in China.
