Abstract: Objective To summarize the clinical experiences and surgical treatment of pulmonary sequestration (PS) in order to improve the diagnosis and treatment of PS. Methods Between August 1993 and February 2007, our department enrolled 21 PS patients, 8 male patients and 13 female patients, with the age ranging from 13 to 70 years old. The patients were examined by chest radiography, computerized tomography (CT), computerized tomography angiography (CTA), magnetic resonance imaging (MRI), position emission tomographyCT(PET-CT) before the surgery. Sequestrectomy was performed on patients with extralobar sequestration (ELS) and lobectomy was performed on patients with intralobar sequestration (ILS). There were 10 cases of left lower lobectomy, 3 cases of right lower lobectomy, 4 cases of left sequestrectomy, 3 cases of right sequestrectomy and 1 case of total pneumonectomy. Results Postoperative pathology confirmed all cases of PS, including 7 cases of ELS and 14 cases of ILS. Seven patients were diagnosed to have PS by preoperative diagnostic procedures. During the surgery, we found aberrant supporting arteries from the general circulation in 18 cases among which 11 were supported by the thoracic aorta, 6 by the abdominal aorta and 1 by both the thoracic and abdominal aorta. The diameter of the aberrant artery was between 0.2 cm and 1.1 cm (mean 0.7 cm). Double ligation and transfixion were performed during the operation. In addition, we found venous drainage through the inferior pulmonary vein in 3 patients and double ligation was performed. No perioperative death or complications occurred. Followup was done till January 2009 on all the patients but one with a followup rate of 95.2% (20/21). The followup time ranged from 12 to 67 months. All patients survived well except that 1 died from liver metastasis 2 years after the operation because of lung cancer. Conclusion PS is rare and its symptoms are nonspecific, which can cause misdiagnosis and missed diagnosis. The diagnosis of PS mainly depends on CT, CTA, MRI and selected arteriography. Once diagnosed, PS should be removed by surgery. During the surgery, aberrant vessels should be separated and treated with double ligation and transfixion. As for those big aberrant vessels, transfixion can be performed after vascular decompression.
ObjectiveTo investigate the safety and feasibility of thoracoscopic lobectomy without mechanical suture.MethodsThe data of 28 consecutive patients (a non-mechanical suture group, 16 males and 12 females at age of 61.23±11.10 years) who underwent non-mechanical suture anatomic thoracoscopic lobectomy performed by the same surgeon from March 2015 to March 2018 were analyzed retrospectively, and 28 patients (18 males and 10 females at age of 59.45±13.39 years) who underwent completely anatomic thoracoscopic lobectomy with endoscopic stapler (a mechanical suture group) in the same period were matched. The clinical effectiveness of the two groups was compared.ResultsThe operation time between the non-mechanical suture group (136.30±53.46 min) and the mechanical suture group (109.63±44.61 min) showed a statistical difference (P<0.05). While in term of intraoperative bleeding volume (65.00 ml vs. 50.00 ml), postoperative thoracic drainage time (3.73 days vs. 3.56 days), thoracic drainage volume (538.60 ml vs. 563.70 ml), postoperative hospital stay (5.58 days vs. 5.35 days) and postoperative complication rate (5/28 vs. 6/28), there was no statistical difference between the two groups. Hospitalization expense was significantly different between the two groups (35 438.30 yuan vs. 51 693.60 yuan).ConclusionNon-mechanical suture thoracoscopic anatomic lobectomy is safe and feasible, and can significantly reduce the medical cost but prolong the operation time.
Objective To investigate the feasibility, curative effect and perioperative treatments of lobectomy for pulmonary diseases by complete videoassisted thoracoscopic surgery (VATS). Methods Fiftysix patients of pulmonary diseases were treated with thoracoscopic lobectomy (including mediastinal and hilar lymph node dissection for malignant diseases) from March 2006 to November 2007 in our Department. Twelve right upper lobectomy, three right middle lobectomy, fifteen right lower lobectomy, nine left upper lobectomy, fourteen left lower lobectomy and three bilobectomy were carried out. The bilobectomy included one right upper and middle lobectomy, two right middle and lower lobectomy. Mediastinal and hilar lymph node dissection was simultaneously performed in the malignant cases. The feasibility, safety and postoperative complications were retrospectively analyzed. Results Fiftytwo patients (92.8%) were performed successfully by complete VATS. The median operative duration and blood loss were respectively 107±29min(from 45min to 168min) and 121±32 ml(from 50ml to 310ml). The incision in two cases (3.6%) were elongated to around 8 cm, the ribs were retracted, and the operations were completed by the help of VATS. Another two patients (3.6%) were changed to conventional thoracotomy for pneumonectomy or hemostasis. The postoperative pathology diagnosis was lung cancer in thirty nine, tuberculoma in seven, inflammatory pseudotumor in four, indurative angioma in four, bronchiectasis in one and metastasic chondrosarcoma in one. There was no surgical mortality. One case suffered from atelectasis in the middle lobe postoperatively and was cured by phlegm suction with bronchoscopy. Two air leakage healed automatically in three days. No other severe complications was observed. The average postoperative hospitalization was 8.9±3.1 d(from 8 d to 14 d). Conclusion Lobectomy for pulmonary diseases by complete VATS is technically fieasible, safe, minimally invasive with less complications and fast rehabilitation.
ObjectiveTo investigate the occurrence of indwelling urinary catheter in patients receiving thoracoscopic lobectomy and relevant risk factors.MethodsWe retrospectively reviewed the clinical data of the 737 patients who received thoracoscopic lobectomy in our hospital and analyzed the risk factors of indwelling urinary catheter during postoperative hospitalization using univariate analysis and multiple-variate logistic regression analysis between December 2018 and May 2019. There were 253 males and 484 females at median age of 57 (50, 64) years.ResultsA percentage of 14.4% (106/737) of the patients adopted postoperative indwelling urinary catheter. Univariate regression analysis showed that gender and postoperative bedridden time were risk factors for indwelling urinary catheter in the patients after thoracoscopic lobectomy (P<0.05). Multiple-variate logistic regression analysis showed that male gender (OR=2.018, 95% CI 1.316-3.096, P<0.001) and postoperative bedridden time >18 hours (OR=2.298, 95%CI 1.502-3.516, P<0.001) were the independent risk factors for indwelling urinary catheter.ConclusionMale gender and those with longer postoperative bedridden time are high-risk population to indwell urinary catheter. Positive measures should be taken to reduce the chance of indwelling urinary catheter.
Abstract： Lung torsion is a very rare clinical event and characterized by rotation of entire lung or individual lobes around the proximal bronchus or blood vessel pedicle in a single direction. The outcomes of lung torsion vary according to different rotation degree. Mild lung rotation may cause hemodynamic changes of the rotated pulmonary tissue. Severe lung rotation may lead to pulmonary venous congestion， lung infarction， systemic intoxication symptoms， ischemia， hypoxia， respiratory failure， severe infection or even death. There are a number of causes of lung torsion， including thoracic surgery， blunt chest trauma， pneumonia， pneumothorax， pleural effusion and lung transplantation. The majority of lung torsion cases occur after thoracic surgeries especially lobectomy， with the right middle lobe being most easily endangered after right upper lobectomy. Lung torsion does not have typical clinical manifestations and thus is difficult to be differentiated from other diseases. Patients with lung torsion often cannot receive correct diagnosis， proper intervention and treatment in time， which may lead to a high mortality. This review focuses on the morbidity， pathogenesis， clinical manifestations， diagnosis， prevention and treatment of lung torsion.
Lobectomy is the standard surgical procedure of non-small cell lung cancer (NSCLC). Based on parenchymal-sparing advantage, better postoperative lung function, rapid recovery and less invasiveness, segmentectomy has been widely used in early peripheral non-small cell carcinoma in recent years. But there was no randomized clinical trials confirming survival benefit of segmentectomy. Led by Asamura, the Japanese Clinical Oncology Group (JCOG) has conducted a series of studies on this topic. Ever since the presentation at the 101st Annual Meeting of the American Society of Thoracic Surgeons (AATS) in 2021, the results of JCOG0802/WJOG4607l have triggered massive debate. This study was aimed at determining whether segmentectomy was non-inferior to lobectomy in overall survival in patients with early peripheral NSCLC (tumor diameter≤2 cm and consolidation tumor ratio>0.5), and the results were published in The Lancet on 22 April 2022. The 5-year overall survival rate was higher in the segmentectomy group than that in the lobectomy group, despite a higher rate of local recurrence, suggesting that segmentectomy should be the standard surgical procedure for those patients. Results of this study provide high-level evidence-based medicine evidence for the safety and effectiveness of segmentectomy, and are expected to promote the application of segmentectomy in those patients or even more other patient populations. However, due to the increased local recurrence rate and unsatisfactory postoperative lung function, there are still problems to be solved to make segmentectomy a standard surgical procedure. This paper interprets this study, discusses its instructiveness in clinical practice and summarizes its limitations.
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 investigate the optimal procedure and short-term efficacy of uniportal video-assisted thoracic surgery (U-VATS) lobectomy for lung cancer. Methods The clinical data of 61 patients who underwent lobectomy using U-VATS by the same surgeon between April 2016 and February 2017 were retrospectively analyzed. There were 50 patients (40 males and 10 females, aged 61.4±6.6 years) with conventional procedure. And there were 60 patients (45 males and 15 females, aged 59.2±9.7 years) utilizing multiportal thoracoscopic surgery (M-VATS) during this period. Results The baseline characteristics in both groups such as age, gender, body mass index, comorbidity and tumor size were comparable (P>0.05). There was no postoperative mortality or conversion to thoracotomy in the study. The parameters such as operative time, blood loss, harvested lymph nodes, duration of chest tube drainage, and length of postoperative hospital stay were similar in both groups (P>0.05). However, there was a statistical difference in pain score at 12 h after surgery in favor of the U-VATS approach (3.2vs.4.3, P=0.04). Moreover, subgroup analysis indicated that the operation time using single-direction U-VATS was noticeably shorter than that in both conventional U-VATS and M-VATS (76.4 minvs.125.8 minvs.105.6 min, P<0.05). However, further analysis was not performed because of small sample. Conclusion The short-term efficacy of U-VATS lobectomy for lung cancer is noninferior to M-VATS, meanwhile, single-direction U-VATS lobectomy is feasible followed by shortened operative time.
ObjectiveThrough the perioperative outcome analysis of da Vinci robot-assisted sleeve lobectomy, to clarify its efficacy and safety.MethodsA retrospective analysis was performed on 10 patients with centrally located lung cancer undergoing robot-assisted sleeve lobectomy from March to December 2019 in our center, including 9 males and 1 female, aged 45-67 (55.0±8.9) years. Preoperative imaging and bronchoscopy showed central non-small cell lung cancer, involving the right upper lung in 3 patients, right lower lung in 2 patients, the left upper lung in 4 patients, and left lower lung in 1 patient. The operation time, Docking time, intraoperative blood loss volume, bronchial anastomosis time, number of dissected lymph nodes, drainage volume and postoperative hospital stay were analyzed.ResultsThe da Vinci robot-assisted bronchial sleeve lobectomy was completed smoothly on 10 patients. The operation time was 135-183 (157.8±14.3) min, Docking time 6-15 (10.0±2.9) min, intraoperative blood loss volume 55-250 (124.5±61.8) mL, bronchial anastomosis time 17-40 (27.7±7.3) min, the number of dissected lymph nodes 16-23 (19.7±2.8), the drainage volume 200-600 (348.0±148.4) mL and postoperative hospital stay 7-11 (8.7±1.6) d. All patients had no bronchopleural fistula, pulmonary infection or atelectasis, and there was no perioperative death. Postoperative pathological findings were all squamous cell carcinoma.ConclusionDa Vinci robot-assisted sleeve lobectomy is safe and effective.
