ObjectiveTo investigate the effects of robotic versus thoracoscopic lobectomy on body trauma and lymphocyte subsets in patients with non-small cell lung cancer (NSCLC).MethodsThe clinical data of 120 patients with NSCLC who underwent lobectomy in the same operation group at the same period were collected and divided into a robot group (n=60) and a thoracoscope group (n=60) according to different surgical methods. The operation time, intraoperative blood loss, postoperative drainage time, drainage volume, postoperative hospital stay, complication rate, pain visual analogue scale (VAS) and other perioperative indicators were recorded in the two groups. Inflammatory markers: C-reactive protein (CRP), interleukin-6 (IL-6) and lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) levels were measured before and 1 d, 3 d after surgery. The effects of the two surgical methods on the body trauma and lymphocyte subsets were compared.ResultsThe operation time, intraoperative blood loss, postoperative drainage time, drainage volume and VAS of the robot group were lower than those of the thoracoscope group, and the differences were statistically significant (P<0.05). On the 1st day after surgery, IL-6 of the thoracoscope group was higher than that of the robot group, while CD3+, CD4+ and CD8+ were lower than those of the robot group, with statistically significant differences (P<0.05).ConclusionCompared with thoracoscopic lobectomy, robotic lobectomy has less trauma, less inflammatory response, faster recovery, less inhibitory effect on lymphocyte subsets, and has clinical advantages.
Objective
To investigate the perioperative outcome of robot-assisted pulmonary lobectomy in treating pathological stage Ⅰ non-small cell lung cancer (NSCLC).
Methods
We retrospectively analyzed the clinical data of 333 consecutive p-T1 NSCLC patients who underwent robotic-assisted pulmonary lobectomy in our hospital between May 2013 and April 2016. There were 231 females (69.4%) and 102 males (30.6%) aged from 20–76 (55.01±10.46) years. Cancer was located in the left upper lobectomy in 37 (11.1%) patients, left lower lobectomy in 71 (21.3%) patients, right upper lobectomy in 105 (31.5%) patients, right middle lobectomy in 32 (9.6%) patients, right lower lobectomy in 88 (26.4%) patients. Adenocarcinoma was confirmed in 330 (99.1%) patients and squamous cell cancer was confirmed in 3 (0.9%) patients.
Results
Total operative time was 46–300 (91.51±30.80) min. Estimated intraoperative blood loss was 0–100 ml in 319 patients (95.8%), 101–400 ml in 12 patients (3.6%), >400 ml in 2 patients (0.6%). Four patients were converted to thoracotomy, including 2 patients due to pulmonary artery branch bleeding and 2 due to pleural adhesion.No patient died within 30 days after surgery. And no perioperative blood transfusion occurred. Postoperative day 1 drain was 0–960 (231.39±141.87) ml. Chest drain time was 2–12 (3.96±1.52) d.And no patient was discharged with chest tube. Length of hospital stay after surgery was 2–12 (4.96±1.51) d. Persistent air leak was in 12 patients over 7 days. No readmission happened within 30 days. All patients underwent lymph node sampling or dissection with 2–9 (5.69±1.46) groups and 3–21 (9.80±3.43) lymph nodes harvested. Total intraoperative cost was 60 389.66–134 401.65 (93 809.23±13 371.26) yuan.
Conclusion
Robot-assisted pulmonary lobectomy is safe and effective in treating p-Stage Ⅰ NSCLC, and could be an important supplement to conventional VATS. Regarding to cost, it is relatively more expensive compared with conventional VATS. RATS will be widely used and make a great change in pulmonary surgery with the progressive development of surgical robot.
Objective
To explore the learning curve and evaluate the safety of uniportal complete video-assisted thoracoscopic surgery (VATS) lobectomy.
Methods
We reviewed retrospectively the clinical data of 133 patients, who underwent uniportal VATS between March 2015 and October 2016 in Sichuan Provincial Cancer Hospital. There were 79 males and 54 females at age of 52.21±10.77 years.
Results
All the 127 patients completed uniportal VATS, 4.51% (6/133) converted to open surgery. There were 78 patients with lobectomy, 6 patients with segmentectomy, 37 patients with wedge resection, 6 patients with pleural, mediastinal lymph node biopsy or mediastinal tumor resection. In the lobectomy group, mean surgical time was 148.75±34.12 min, mean blood loss was 118.87±59.96 ml, mean number of lymph nodes was 11.25±6.15, the mean duration of chest-tube placement was 2.17±1.35 days, and mean length of stay was 7.58±2.59 days.
Conclusion
Based on skillful performance of the conventional thoracoscopic lobectomy, the learning curve for single port thoracoscopic lobectomy comprises at least 20 patients. The uniportal VATS lobectomy is a safe and operable method of minimally invasive technique, and it is worthy to be applied in thoracic surgery.
Objective
To develop a novel methylene blue staining technique to localize small esophageal leiomyomas (<1.5 cm) and evaluate its feasibility.
Methods
Between January 2013 and October 2016, 9 patients with small esophageal leiomyomas (<1.5 cm) underwent thoracoscopic enucleation in Tongji Hospital. There were 5 males and 4 females with an average age of 51 years. We preoperatively injected 0.5–1.0 ml methylene blue in the submucosa adjacent to the tumors under the guidance of gastroscope. Then, we transferred the patients to the operating room.
Results
Staining was successful in 9 patients. The unstained tumor was exposed after the blue-stained mediastinal pleura and overlying muscle were incised longitudinally during video-assisted thoracoscopic surgery via one utility port. No abnormalities were detected in the esophageal mucosa. No major complications, such as esophageal leakage or esophageal diverticulum occurred.
Conclusion
Endoscopic methylene blue staining is safe and feasible for localizing small esophageal leiomyomas during video-assisted thoracoscopic surgery via one utility port. This method will enable enucleation precise and easy.
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.
Recently, the frequency of lung disease appears higher and more precise than previously estimated. Small pulmonary nodules (SPNs) are frequently detected on high-resolution computed tomography (CT) scans. For the reason of high rate of false positives by fine needle aspirate biopsy, small lung nodules often can not be confirmed by monitor or palpation with forceps. How to precisely locate and mark the nodule before the surgery is one of the most important things for video-assisted thoracoscopic surgery (VATS). We reviews the methods of location the pulmonary nodules before the surgery and analyzes the advantages and disadvantages of various methods.
Surgical treatment is an important treatment for spontaneous pneumothorax, which can remove the gas in the pleural cavity, relieve symptoms, promote lung recruitment, moreover, prevent future recurrence. The surgical modalities included video-assisted thoracoscopic surgery (VATS) and non VATS treatment. Nowadays, the treatment of spontaneous pneumothorax has entered a minimally invasive era. With the development of minimally invasive techniques in recent years, as the representative of minimally invasive surgery, the surgeon techniques of VATS has developed to diversity, including three-port VATS, two-port VATS, uniportal VATS, subxiphoid uniportal VATS, 3D VATS, robotic-assisted VAT and cervical uniportal VATS. Each technique has its own advantages and limitations, and individual choices should be made.
ObjectiveTo evaluate the feasibility and clinical effect of controlled hypotension in video-assisted thoracoscopic surgery (VATS) for subcarinal lymph node dissection in patients with lung cancer.MethodsWe analyzed the clinical data of 53 non-small cell lung cancer (NSCLC) patients undergoing VATS with controlled systolic blood pressure while dissecting the subcarinal lymph node from September to October 2016 in our department (a treatment group, including 31 males and 22 females with an average age of 53.20±8.80 years ranging 43-68 years). We selected 112 NSCLC patients undergoing VATS without controlled systolic blood pressure while dissecting the subcarinal lymph node from January to August 2016 in our department (a contol group, including 67 males and 45 females with an average age of 54.32±7.81 years ranging 39-73 years). The clinical data of both groups were compared.ResultsThe operation time and blood loss of the treatment group were less than those of the control group (177.6±39.4 min vs. 194.3±47.8 min, 317.9±33.6 ml vs. 331.2±38.7 ml, P<0.05). The duration of subcarinal lymph node dissection and total duration of lymph node dissection of the treatment group were also less than those of the control group (10.5±4.3 min vs. 13.6±5.2 min, 37.7±7.5 min vs. 48.7±6.4 min, P<0.001). The thoracic drainage at postoperative days 1, 2, 3 and total drainage volume, duration of tube placement and hospital stay of the treatment group were less than those of the control group (P<0.05). Whereas the postoperative complications of the two groups did not differ significantly (P>0.05).ConclusionControlled hypotension reduces the difficulty of dissecting subcarinal lymph nodes and the risk of bleeding, and produces less drainage volume, which is safe and effective.
The precise resection and suture of bronchia, vascular and pulmonary tissue are the key techniques in thoracic surgery. Mechanical suture technique has gradually become a routine operation in thoracic surgery. However, at present, there is still a lack of consensus and guidelines on the application of this technique in thoracic surgery, neither strong evidence-based medical support. In this study, we discuss the application standard of mechanical suture technique in thoracoscopic surgery, irregular treatment techniques, intraoperative complications, and management principles to promote the standardized application of mechanical suture technique. We also explain the shortcomings of the technique in order to promote the further improvement and perfection.

(Shanghai Lung Tumor Clinical Medical Center, Department of Thoracic Surgery, Shanghai Chest Hospital, Shanghai 200030, P. R. China) Corresponding author：LUO Qing-quan, Email：luoqingquan@hotmail. com Abstract： Objective To explore the feasibility and safety of single-direction four-hole video-assisted thoracoscopic lobectomy in the treatment of non-small cell lung cancer (NSCLC). Methods Between January 2007 and December 2010, 428 patients with NSCLC were surgically treated by single-direction complete video-assisted thoracoscopic lobectomy in Shanghai Chest Hospital. There were 186 males and 242 females; aged 33 to 78 years. All the patients were diagnosed as primary NSCLC at early clinical stage. Among the 428 patients, 134 patients underwent right upper lobectomy, 48 patients underwent right middle lobectomy, 98 patients underwent right lower lobectomy, 4 patients underwent right middle and lower lobectomy, 72 patients underwent left upper lobectomy, and 72 patients underwent left lower lobectomy. All the 428 patients were divided into two groups according to their surgical approach：a three-hole group (300 patients) and a four-hole group (128 patients).The clinical results of the two groups were analyzed. Results A total of 412 patients underwent complete video-assisted thoracoscopic lobectomy, and 16 patients (3.7%) underwent conversion to open surgery. The average operation time was 132.1 (120-180) min, average length of incision was 3.7 (3-5) cm, and average blood loss was 150.0 (50-800) ml. There was no statistical difference in extubation time, intraoperative blood loss, and postoperative hospital stay between the two groups. But the operation time of the four-hole group is significantly shorter than that of the three-hole group （P＜0.05）. The 16 patients who underwent conversion to open surgery received intraoperative blood transfusion. Five patients died of severe pulmonary infection, pulmonary embolism, and acute cerebral infarction. Fifty two patients had squamous cancer, 340 patients had adenocarcinoma, 20 patients had adenosquamous carcinoma, 8 patients had poorly differentiated carcinoma, 6 patients had big cell lung cancer, and 2 patients had carcinoid. Postoperative persistent lung air leak occurred in 4 patients, thoracic empyema in 2 patients, pulmonary infection in 4 patients, arrhythmia in 26 patients, pulmonary embolism in 2 patients, chylothorax in 2 patients, and acute cerebral infarction in 2 patients. The overall 3-year survival rate was 83.6%（358/428）. Conclusion Single-direction four-hole complete video-assisted thoracoscopic lobectomy is feasible, safe and consistent with the operation standard in the surgical treatment for NSCLC patient. It is also helpful to reduce the operation time and facilitate lymph node dissection.
