Objective To investigate the perioperative differences between video-assisted thoracoscopic surgery (VATS) and thoracotomy after neoadjuvant therapy in patients with non-small cell lung cancer (NSCLC). Methods Clinical data of NSCLC patients who underwent VATS or thoracotomy after neoadjuvant therapy at Shanghai Pulmonary Hospital from June 2020 to May 2022 were retrospectively collected. Perioperative outcomes were compared between the two groups. Results A total of 260 patients were enrolled, 184 (70.8%) patients underwent VATS and 76 (29.2%) patients underwent thoracotomy. After propensity matching, there were 113 (62.4%) patients in the VATS group and 68 (37.6%) patients in the thoracotomy group. VATS had similar lymph node dissection ability and postoperative complication rate with thoracotomy (P>0.05), with the advantage of having shorter operative time (146.00 min vs. 165.00 min, P=0.006), less intraoperative blood loss (50.00 mL vs. 100.00 mL, P<0.001), lower intraoperative blood transfusion rate (0.0% vs. 7.4%, P=0.003), less 3-day postoperative drainage (250.00 mL vs. 350.00 mL, P=0.011; 180.00 mL vs. 250.00 mL, P=0.002; 150.00 mL vs. 235.00 mL, P<0.001), and shorter postoperative drainage time (9.34 d vs. 13.84 d, P<0.001) and postoperative hospitalization time (6.19 d vs. 7.94 d, P=0.006). Conclusion VATS after neoadjuvant therapy for NSCLC is safer than thoracotomy and results in better postoperative recovery.
ObjectiveTo compare the short-term clinical effects of Da Vinci robot-assisted thoracic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) in the treatment of posterior mediastinal tumors, and to explore the advantages of RATS posterior mediastinal tumor resection. MethodsThe clinical data of patients who underwent posterior mediastinal tumors resection through the lateral chest approach admitted to the same medical group in the Department of Thoracic Surgery of the First Hospital of Lanzhou University between January 2019 to January 2023 were retrospectively analyzed. According to the different surgical methods, the patients were divided into a RATS group and a VATS group. The clinical data were compared between the two groups. ResultsA total of 85 patients were included in this study. There were 39 patients in the RATS group, including 25 females and 14 males, with an average age of 47.6±13.0 years, and 46 patients in the VATS group, including 14 males and 32 females, with an average age of 45.3±14.7 years. All patients completed the operation successfully. The hospitalization cost in the RATS group was significantly higher than that in the VATS group (P<0.001), and the white blood cell count and neutrophilic granulocyte percentage on the first day after operation in the RATS group were lower than those in the VATS group, and the differences were statistically significant (P<0.05). The operative time, intraoperative bleeding, postoperative hospital stay, white blood cell count and neutrophil percentage on the third postoperative day, visual analogue scale score on the first and third postoperative days, duration of analgesic pump use, postoperative 12 h oxygen saturation (no oxygen inhalation), postoperative down bed time, total thoracic drainage volume, duration of drainage tube retention, and postoperative complication rates were not statistically different between the two groups (P>0.05). There was no perioperative death, conversion to thoracotomy or serious perioperative complications in both groups. ConclusionRATS resection of posterior mediastinal tumor via lateral thoracic approach is safe and feasible, and its short-term effect is similar to that of VATS via lateral thoracic single-hole approach. It is worth further comparative study to explore its benefit and cost performance.
ObjectiveTo investigate the feasibility and clinical effect of controlled hypotension in 3 cm single-port video-assisted thoracoscopic surgery (VATS) for the lymph node group 7 dissection in the left lung resection.
MethodsWe retrospectively analyzed the clinical data of 37 patients with lung cancer who underwent 3 cm single-port VATS from May 2015 to August 2015 in Tongji Hospital, and systolic blood pressure of 12 patients (7 males, 5 females, average age of 58.3 years, range 42-69 years) was controlled between 80-90 mm Hg by nitroglycerin or sodium nitroprusside while the pressure of 25 patients (14 males, 11 females, average age of 57.7 years, range 43-68 years) was not controlled when receiving lymph node group 7 dissection.
ResultsControlled hypotension in lymphadenectomy achieved satisfactory results. The lymphadenectomy time of 12 patients with controlled hypotension (18.5±4.3 min on average, range 15.6-25.3 min) was shorter than that of 25 patients without controlled hypotension (24.3±5.1 min on average, range 18.2-29.8 min); the difference was statistically significant (P<0.05).
ConclusionControlled hypotension is a simple and feasible method that increases the operating space, and reduces the difficulty of cleaning lymph nodes and the risk of bleeding.
ObjectiveTo evaluate the feasibility and safety of improving chest drainage procedure by applying postoperative chest drainage with central venous catheter for uniportal video-assisted thoracoscopic surgery (VATS) lobectomy in fast track recovery. MethodsBetween July 2016 and March 2018, a total of 150 patients who underwent uniportal VATS lobectomy by the same chief surgeon were recruited. All patients were randomly divided into two groups including a trial group and a control group. In the trial group, there were 44 males and 28 females with an average age of 47±11 years. Central venous catheter and 26F silicone rubber tuber were used and chest tube was removed when drainage volume less than 300 ml/d. Chest X ray was conducted three days after discharge from hospital and the central venous catheter was removed after thoracentesis. In the control group, there were 40 males and 29 females with an average ages of 52±13 years, 26 F silicone rubber tuber and chest tube were removed when drainage volume less than 100 ml/d. The clinical effectiveness was compared between the two groups. ResultsNo statistically significant difference was observed between the trial group and the control group in the date of preoperative general information, the occurrence of postoperative complications and the visual analogue score on Day1 after the operation. However, the visual analogue score, intubation time, post-operative length of stay, the frequency of using tramadol were all significantly shorter or lower in the trial group when compared with the control group (P<0.05). Seven patients of the trial group suffered moderate pleural effusion after intubation, which was significantly more than that of the control group (P<0.05). Six patients recovered after thoracentes through central venous catheter. The average amount of pleural effusions before removing the central venous catheter was 74.8 ml. ConclusionThe use of central venous catheter and 26 F silicone rubber tuber after uniportal VATS lobectomy is safe and feasible for the early removal of chest tube. It is beneficial to fast track recovery.
Objective To compare the safety and efficacy of the da Vinci robot and thoracoscopic subxiphoid approach for the treatment of anterior mediastinal tumors. Methods The clinical data of patients who underwent anterior mediastinal tumor resection through the subxiphoid approach admitted to the same medical group in the Department of Thoracic Surgery of the First Hospital of Lanzhou University between June 2020 and April 2022 were retrospectively analyzed. According to the surgery approach, the patients were divided into a robot-assisted thoracoscopic surgery (RATS) group and a video-assisted thoracoscopic surgery (VATS) group. The perioperative data and the incidence of postoperative complications were compared between the two groups. ResultsA total of 79 patients were enrolled. There were 41 patients in the RATS group, including 13 males and 28 females, with an average age of 45.61±14.99 years. There were 38 patients in the VATS group, including 14 males and 24 females, with an average age of 47.84±15.05 years. All patients completed the surgery successfully. Hospitalization cost and operative time were higher or longer in the RATS group than those in the VATS group, and the difference was statistically significant (P<0.05). Intraoperative bleeding, postoperative hospital stay, postoperative water and food intake time, postoperative off-bed activity time, white blood cell count, neutrophil percentage and visual analogue scale (VAS) score on the first postoperative day, white blood cell count and neutrophil percentage on the third postoperative day, duration of analgesic pump use, the number of voluntary compressions of the analgesic pump, and mediastinal drainage volume were all superior to those in the VATS group (P<0.05). The differences in VAS scores on the third postoperative day, duration of drainage tube retention and postoperative complication rates were not statistically different between the two groups (P>0.05). Conclusion RATS subxiphoid anterior mediastinum tumor resection is a safe and feasible surgical method with less injury and higher safety, which is conducive to rapid postoperative recovery and has wide clinical application prospects.
ObjectiveTo compare the effect on postoperative immune function between da Vinci robot-assisted thoracoscopic surgery (RATS) and video-assisted thoracoscopic surgery (VATS) , and to provide clinical support for more effective surgical procedures.MethodsA total of 90 patients undergoing radical resection of pulmonary carcinoma in our hospital from June to November 2019 were included. There were 49 males and 41 females with an average age of 62.67 (37-84) years. Among them, 50 patients underwent da Vinci robot-assisted thoracoscopic surgery (a RATS group) and 40 patients underwent video-assisted thoracoscopic surgery (a VATS group). The perioperative indexes as well as postoperative inflammatory factors and immune level effects between the two groups were compared.ResultsCompared with the VATS, RATS could significantly shorten the operation time and decrease intraoperative blood loss (P<0.05). RATS also effectively reduced the increase of postoperative inflammatory factor level (P<0.05). But there was no significant difference in postoperative immune function between the RATS group and the VATS group (P>0.05).ConclusionRATS is superior to VATS in the treatment of non-small cell lung cancer in perioperative indicators and inflammatory factors.
ObjectiveTo explore the learning curve of single pore video-assisted thoracoscopic surgery (VATS) for the treatment of pulmonary bullae.
MethodsFrom July 2010 to October 2011, sixty consecutive patients with pulmo-nary bulla undergoing single pore VATS by the same group of surgeons in the Department of Thoracic and Cardiovascular Surgery, Songgang People's Hospital. According to the sequence of the operations, all the patients were divided into group A, B, and C with 20 patients in each group. Operation time, intraoperative blood loss, postoperative hospital stay and thoracic drainage duration were compared between the 3 groups to evaluate surgical outcomes in different stages. Operation time and postoperative hospital stay were the main indexes of the learning curve.
ResultsThere was no statistical difference in age, gender or incidence of pneumothorax between the 3 groups (P > 0.05). Operation time of group A (42.7±9.4 minutes) was significantly longer than those of group B (21.3±6.7 minutes) and group C (20.8±7.5 minutes) (P < 0.01). Postoperative hospital stay of group A (10.6±2.2 days) was significantly longer than those of group B (7.6±1.2 days) and group C (7.4±1.2 days) (P < 0.05). There was no statistical difference in other indexes among the 3 groups (P > 0.05).
ConclusionThe learning curve of single pore VATS for the treatment of pulmonary bullae is approximately 20 cases.

Objective To investigate clinical outcomes of complete video-assisted thoracoscopic lobectomy and summarize our preliminary experience. Methods Clinical data of 60 consecutive patients who underwent complete video-assisted thoracoscopic lobectomy in General Hospital of Chengdu Military Command from March 2010 to August 2011 were retrospectively reviewed. There were 37 male patients and 23 female patients with their median age of 52.1 （17-77） years. There were 7 patients undergoing left upper lobectomy， 19 patients undergoing left lower lobectomy， 12 patients undergoing right upper lobectomy， 3 patients undergoing right middle lobectomy， 17 patients undergoing right lower lobectomy， and 2 patients undergoing combined right middle and lower lobectomy. Results The average operation time was 161 （50-270） minutes， average intra-operative blood loss was 310 （50-800） ml， average number of lymph node dissection was 13.4 （6-29）， average postoperative thoracic drainage was 950 （250-2 800） ml， average duration of thoracic drainage was 4.6 （3-11） days， average intensive care unit stay was 1.2 （1-3） days， and average postoperative hospital stay was 7.7（4-14） days. None of the patients had any severe postoperative complication. Fifty-two patients were followed up for 7 to 24 months， and 8 patients were lost during follow-up. During follow-up， 5 patients had lung cancer metastases， including 2 patients with mediastinal lymph node metastases and 3 patients with distant metastases. After chemoradiotherapy，3 patients lived well but 2 patients died. None of the other patients had any severe complication during follow-up. Conclusion Complete video-assisted thoracoscopic lobectomy is a safe and effective surgical strategy for patients with benign or malignantpulmonary disease.
ObjectiveTo evaluate the correlation between positive end-expiratory pressure (PEEP) level and postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung surgery. MethodsThe clinical data of patients who underwent elective thoracoscopic lung surgery at West China Hospital of Sichuan University from January 2022 to June 2023 were retrospectively analyzed. Patients were divided into 2 groups according to intraoperative PEEP levels: a PEEP 5 cm H2O group and a PEEP 10 cm H2O group. The incidence of PPCs in the two groups after matching was compared using a nearest neighbor matching method with a ratio of 1∶1, setting the clamp value as 0.02. ResultsA total of 538 patients were screened, and after propensity score-matching, a total of 229 pairs (458 patients) were matched, with an average age of 53.9 years and 69.4% (318/458) females. A total of 118 (25.8%) patients had PPCs during hospitalization after surgery, including 60 (26.2%) patients in the PEEP 5 cm H2O group and 58 (25.3%) patients in the PEEP 10 cm H2O group, with no statistically significant difference between the two groups [OR=0.997, 95%CI (0.495, 1.926), P=0.915]. Multivariate logistic regression analysis showed that PEEP was not an independent risk factor for PPCs [OR=0.920, 95%CI (0.587, 1.441), P=0.715]. ConclusionFor patients undergoing thoracoscopic lung surgery, intraoperative PEEP (5 cm H2O or 10 cm H2O) is not associated with the risk of PPCs during hospitalization after surgery, which needs to be further verified by prospective, large-sample randomized controlled studies.
