ObjectiveTo analyze the feasibility, advantages and disadvantages of the fluorescence method and the inflation-deflation method in defining the intersegmental plane during thoracoscopic lung segmental resection.MethodsFrom February to October 2018, 60 patients underwent thoracoscopic anatomical segmentectomy in Thoracic Surgery Department of Nanjing Chest Hospital, with 28 males and 32 females, aged from 25 to 82 years. Three-dimension computed tomography bronchography and angiography was used to reconstruct pulmonary vessels, bronchus and virtual intersegmental plane. Among them, 20 patients used the fluorescence method to define the intersegmental plane, and the other 40 patients used the traditional inflation-deflation method to define the intersegmental plane.ResultsFluorescent injection of indocyanine green (ICG) showed a clear intersegmental line with a duration sufficient to complete the label. With the fluorescence method, the intersegmental plane occurrence time was significantly shortened (10.75±3.78 s vs. 988.00±314.24 s, P<0.001) and had satisfactory repeatability. The lungs did not need to be inflated, which was convenient for the operation. And the operation time was shortened (108.75±31.28 min vs 138.00±32.47 min, P=0.002). No obvious ICG injection-related concurrency symptoms was found.ConclusionCompared with the traditional inflation-deflation method, the fluorescence method can display the intersegmental line quickly, accurately and clearly, reduce the difficulty of surgery, shorten the operation time, and provide reliable technical support for thoracoscopic anatomical segmentectomy. The fluorescence is a safe and effective method that is worthy of clinical application.
ObjectiveTo investigate the clinical effect of thoracoscopic lobectomy versus segmentectomy in the treatment of T1bN0M0 non-small cell lung cancer (NSCLC). MethodsClinical data of 181 patients with T1bN0M0 NSCLC admitted to our hospital from 2012 to 2015 were retrospectively analyzed. They were divided into a lobectomy group and a segmentectomy group according to surgical methods. There were 117 patients in the lobectomy group (46 males and 71 females aged 61.32±8.94 years) and 64 patients in the segmentectomy group (20 males and 44 females aged 58.55±12.57 years). Perioperative indicators and prognosis were compared between the two groups. ResultsThe segmentectomy group had longer operation time, less intraoperative blood loss, shorter postoperative hospital stay and more preservation of lung function compared with the lobectomy group (P<0.05). The lobectomy group had higher consolidation tumor ratio, bigger tumor diameter, and more lymph node sampling compared with the segmentectomy group (P<0.05). There was no statistical difference in 5-year overall survival or recurrence-free survival between the two groups (P<0.05). ConclusionFor patients with T1bN0M0 NSCLC, thoracoscopic segmentectomy and lobectomy have similar prognosis, but segmentectomy has advantages with less injury and faster recovery over lobectomy.
ObjectiveTo investigate the diagnostic value of internal medicine thoracoscope combined with pleural GeneXpert MTB/RIF for tuberculous pleurisy.MethodsEighty patients with tuberculous pleurisy admitted to hospital with pleural effusion were treated as tuberculous pleurisy group, and 20 patients with clinical diagnosis of malignant pleural effusion were used as control group. After admission to the hospital, the pre-operative examination of internal medicine thoracoscope were analyzed. All patients were extracted pleural effusion with thoracic puncture in order to send pleural tuberculosis smear and culture. Patients who had no contraindications were arranged internal medicine thoracoscope to get pleural effusion which will be sent to GeneXpert MTB/RIF and pathological tissue biopsy.ResultsIn the tuberculous pleurisy group, nine patients were positive in pleural tuberculous smear, and the positive rate was 11.3%; 4 patients were positive in pleural tuberculous culture, and the positive rate was 5.0%; 75 patients were diagnosed with pathological biopsy, and the positive rate was 93.8%; 69 patients were positive with pleural GeneXpert MTB/RIF, and the positive rate was 86.3%. The positive rate of internal medicine thoracoscopic pleural biopsy combined with pleural GeneXpert MTB/RIF could reached 96.3%. The pleural GeneXpert MTB/RIF lifampin resistance gene was positive in 5 patients, 4 of them were positive for tuberculosis culture, and the drug sensitivity results showed rifampicin resistance. In the control group, patients had negative result in pleural effusion tuberculosis smear, tuberculosis culture and the pleural GeneXpert MTB/RIF.ConclusionsThe diagnosis of tuberculous pleurisy by the combination of internal medicine thoracoscope and pleural GeneXpert MTB/RIF has high specificity and sensitivity. The diagnosis of tuberculous pleurisy by the combination of internal medicine thoracoscope and pleural GeneXpert MTB/RIF has high specificity and sensitivity, which has the value of rapid and accurate diagnosis and early guidance of anti-tuberculosis chemotherapy based on the early judgment of whether rifampin resistance exists.
ObjectiveTo analyze the feasibility and advantages of non-intubated anesthesia in thoracoscopic lobectomy.MethodsThe clinical data of 59 patients with thoracoscopic lobectomy and non-intubated anesthesia in the Department of Thoracic Surgery, Tongji Hospital from January 2015 to December 2017 were retrospectively reviewed, including 24 males and 35 females, aged 56.86±7.13 years (an observation group); 59 patients with thoracoscopic lobectomy undergoing general anesthesia with tracheal intubation in the same period were randomly selected, as a control group, including 27 males and 32 females, aged 55.37±6.86 years. Complications such as airway injury, refractory cough, pharyngalgia, nausea and vomiting were compared between the two groups. Postoperative inflammatory factor levels, postoperative hospital stay, and intraoperative and postoperative hospitalization costs were also compared.ResultsThere was no difference between the two groups in general conditions such as age, gender, body mass index. There was also no difference in operation time, intraoperative bleeding volume or lymph node dissection. But the observation group had lower levels of procalcitonin and C reactive protein at postoperative 1 d (0.12±0.51 ng/ml vs. 0.14±0.70 ng/ml, P=0.03; 11.30±3.60 mg/L vs. 13.33±4.41 mg/L, P=0.01), lower rate of postoperative complications of refractory cough, pharyngalgia, nausea and vomiting (3.38% vs. 15.25%, P=0.03; 5.08% vs. 20.33%, P=0.01; 3.38% vs. 15.25%, P=0.03), less retain time of thoracic duct, postoperative hospital stay, and lower intraoperative and postoperative hospitalization costs (5.89±1.37 d vs. 7.00±1.73 d, P=0.00; 10.01±1.85 d vs. 11.37±2.45 d, P=0.00; 53 810.94±5 745.44 yuan vs. 58 223.16±6 445.08 yuan, P=0.00).ConclusionThoracoscopic lobectomy with non-intubated anesthesia can avoid traditional airway injury caused by endotracheal intubation, reduce postoperative symptoms such as refractory cough, pharyngalgia, nausea and vomiting caused by general anesthesia, reduce or even avoid lung injury caused by one-side lung ventilation, promote recovery after surgery, reduce antibiotic use, and shorten hospital stay, which is more consistent with the requirements of the concept of overall minimal invasiveness and enhanced recovery.
Objective To explore the factors of postoperative cough in lung cancer patients. Methods Totally 130 lung cancer patients of single medical team (average age of 58.75±9.34 years, 65 males and 65 females), from February 2016 to February 2017 in the Department of Thoracic Surgery of West China Hospital of Sichuan University, were investigated by Mandarin Chinese version of the Leicester Cough Questionnaire (LCQ-MC). We analyzed and calculated the preoperative and postoperative scores of LCQ-MC, Cronbach α and the influencing factor. Results The preoperative score of LCQ-MC's physiological dimension was significantly lower in the postoperative cough group (6.30±0.76) than that of the postoperative non-cough group (6.56±0.60,P=0.044), while the preoperative total score of LCQ-MC (19.53±1.78, 20.03±1.45) was not statistically different (P=0.080). The postoperative score of LCQ-MC was significantly lower in the postoperative cough group (17.32±2.79) than that of the postoperative non-cough group (19.70±1.39,P<0.001). And the scores of physiological, psychological and social dimension were significantly lower in the postoperative cough group (5.32 ±1.14, 5.73±1.14, 6.23±0.89) than those of the postoperative non-cough group (6.25±0.63, 6.67±0.54, 6.78±0.49) (P values were all less than 0.001). The result of multi-factor logistic regression analysis showed the condition of preoperative cough symptom (OR=0.354, 95%CI=0.126–0.994, P=0.049) and anesthesia time (OR=1.021, 95% CI=1.003–1.040, P=0.021) were the risk factors. Conclusion The risk factors of postoperative cough symptoms in lung cancer patients are the condition of preoperative cough symptoms and anesthesia time.
ObjectiveTo investigate the safety and efficacy of totally no tube three-port thoracoscopic surgery (TNTT) for thymic tumor via lateral thoracic approach. MethodsThe clinical data of patients with thymoma admitted to the Department of Thoracic Surgery of the General Hospital of Northern Theater Command from November 2021 to May 2022 were retrospectively analyzed. The patients were divided into a TNTT group and a single utility port video-assisted thoracic surgery (SVATS) group according to different surgical methods. The clinical data were compared between the two groups. ResultsA total of 111 patients were collected. There were 44 patients in the TNTT group, including 20 males and 24 females, with an average age of 60.11±8.64 years, and 67 patients in the SVATS group, including 30 males and 37 females, with an average age of 62.40±7.92 years. There was no significant difference between the two groups in the baseline data (P>0.05). The postoperative hospital stay and intraoperative blood loss were shorter or less in the TNTT group (P<0.05), and the visual analogue scale score 48 hours after the operation was smaller in the SVATS group (P<0.05). ConclusionTNTT has a good surgical safety, and can shorten postoperative hospital stay, reduce intraoperative blood loss, and has significant advantages in enhanced recovery after surgery, but SVATS can reduce postoperative pain in patients.
Objective To analyze the feasibility of totally no tube (TNT) in da Vinci robotic mediastinal mass surgery and its significance for fast track surgery. Methods A total of 79 patients receiving robotic mediastinal TNT surgery in the General Hospital of Shenyang Military Command from January 2016 to December 2017 were enrolled as a TNT group; 35 patients receiving robotic mediastinal surgery in General Hospital of Shenyang Military Command from January 2014 to December 2017 and 54 patients receiving thoracoscopic mediastinal surgery during the same period were enrolled as a non-TNT group and a video-assisted thoracoscopic surgery (VATS) group. The muscle relaxation and tracheal intubation/laryngeal masking time, operation time, intraoperative blood loss, postoperative ICU stay, postoperative hospital stay, postoperative visual analogue scale (VAS), hospitalization costs and postoperative complications and other related indicators were retrospectively analyzed among the three groups. Results Surgeries were successfully completed in 168 patients with no transfer to thoracotomy, serious complications (postoperative complications in 9 patients) or death during the perioperative period. All patients were discharged. Compared with the non-TNT group, the TNT group had significantly less muscle relaxation-tracheal intubation/laryngeal masking time, operation time, intraoperative blood loss, VAS pain score, ICU stay, postoperative hospital stay (P<0.01); there was no significant difference in the total cost of hospitalization between the two groups (P>0.05). Between the non-TNT group and the VATS group, there was no significant difference in time of muscle relaxation and tracheal intubation, operation time and ICU stay (P>0.05). The non-TNT group was superior to the VATS group in terms of intraoperative blood loss, VAS pain scores on the following day after operation, chest drainage volume 1-3 days postoperatively, postoperative catheterization time and postoperative hospital stay (P<0.05); but the cost of hospitalization in the non-TNT group was significantly higher (P=0.000). Conclusion The da Vinci robot is safe and feasible for the treatment of mediastinal masses. At the same time, TNT is also safe and reliable on the basis of robotic surgery which has many advantages such as better comfort, less pain, ICU stay and hospital stay as well as faster recovery.
ObjectiveTo investigate the safety and efficacy of naked eye 3D thoracoscopic surgery in minimally invasive esophagectomy.MethodsClinical data of 65 patients, including 50 males and 15 females aged 47-72 years, with esophageal cancer who underwent minimally invasive thoracoscopic esophagectomy from October 2018 to April 2019 were retrospectively analyzed. Patients were divided into two groups according to different surgical methods including a naked eye 3D thoracoscopic group (group A: 30 patients) and a traditional 2D thoracoscopic group (group B: 35 patients). The effects of the two groups were compared.ResultsThe operation time in the group A was significantly shorter than that in the group B (P<0.05). The number of dissected lymph nodes in the group A was more than that in the group B (P<0.05). The thoracic drainage volumes on the 1th-3th days after operation in the group A were significantly larger than those in the group B (P<0.05), but there was no significant difference between the two groups on the 4th-5th days after operation (P>0.05). The indwelling time in the group A was longer than that in the group B (P<0.05). Postoperative hospital stay, pulmonary infection, arrhythmia, anastomotic leakage, and recurrent laryngeal nerve injury were not significantly different between the two groups (P>0.05).ConclusionNaked eye 3D thoracoscopic surgery for minimally invasive esophagectomy is a safe and effective surgical procedure. Compared with traditional 2D minimally invasive thoracoscopic surgery, it is safer in operation and more thorough in clearing lymph nodes. The operation is more efficient and can be promoted.
ObjectiveTo evaluate the safety and the clinical curative effect of mediastinal tumor resection by video-assisted thoracoscopic surgery(VATS） with spontaneous breathing under intravenous anesthesia, comparing with endotracheal tube anesthesia.MethodsThe data of 43 patients, aged 28–58 years, with mediastinal benign tumors which had been cofirmed by chest CT in our hospital were retrospectively analyzed. Among them, 18 patients underwent mediastinal tumor resection by VATS with spontaneous breathing under intravenous anesthesia, 25 patients by endotracheal tube anesthesia.The differences, including the time of anesthesia intubation and extubation, operation time and intraoperative blood loss, muscle strength at 4 hours and at 24 hours after operation, pain score at 24 hours after operation, hospitalization time, were be compared between the two groups.ResultsThe duration of intubation (17.8±4.8 min) in spontaneous breathing under intravenous anesthesia group was shorter than another group (28.6±8.17 min), the difference was statistically significant (P<0.05). Muscle strength at 4 hours after operation in spontaneous breathing under intravenous anesthesia group was significantly higher than another group (38.5±6.5 kg vs. 28.3±5.2 kg, P<0.05) as well. However, there was no significant difference between the two groups in extubation time, operation time and intraoperative blood loss, muscle strength and pain score at 24 hours after operation, hospitalization time.
ObjectiveTo analyze risk factors for chronic cough after minimally invasive resection of non-small cell lung cancer (NSCLC) and explore the possible prevention measures.MethodsA total of 128 NSCLC patients who received minimally invasive resection in 2018 in our hospital were enrolled, including 63 males and 65 females with an average age of 60.82±9.89 years. The patients were allocated into two groups: a robot-assisted thoracic surgery (RATS) group (56 patients) and a video-assisted thoracic surgery (VATS) group (72 patients). Chronic cough was assessed by visual analogue scale (VAS), meanwhile, other perioperative indicators were compared between the two groups. Univariate and multivariate logistic regression analyses were performed to identify risk factors for postoperative chronic cough and explore the prevention strategies.ResultsOverall, 61 (47.7%) patients were diagnosed with chronic cough after surgery, including 25 (44.6%) patients in the RATS group and 36 (50.0%) patients in the VATS group, and the difference was not statistically significant (P>0.05). Compared with the VATS group, the RATS group got shorter endotracheal intubation time (P=0.009) and less blood loss (P<0.001). The univariate analysis showed that age (P=0.014), range of surgery (P=0.021), number of dissected lymph nodes (P=0.015), preoperative cough (P=0.006), endotracheal intubation time (P=0.004) were the influencing factors for postoperative chronic cough. The multivariate analysis showed that age <57 years (OR=3.006, 95%CI 1.294-6.986, P=0.011), preoperative cough (OR=3.944, 95%CI 4.548-10.048, P=0.004), endotracheal intubation time ≥172 min (OR=2.316, 95%CI 1.027-5.219, P=0.043), lobectomy (OR=2.651, 95%CI 1.052-6.681, P=0.039) were the independent risk factors for chronic cough.ConclusionThere is no statistical difference in postoperative chronic cough between the RATS and VATS groups. The RATS group gets less blood loss and shorter endotracheal intubation time. Patients with younger age (<57 years), preoperative cough, lobectomy, and longer duration of endotracheal intubation (≥172 min) are more likely to have chronic cough after surgery.
