Abstract： Objective To compare clinical outcomes of complete video-assisted thoracoscopic surgery （cVATS） lobectomy with routine thoracotomy lobectomy for the treatment of bronchiectasis, and evaluate the feasibility, safety and specific considerations of cVATS lobectomy for the treatment of bronchiectasis. Methods We retrospectively analyzed the clinical data of 115 patients who underwent lobectomy for the treatment of bronchiectasis in Beijing Chaoyang Hospital from May 2009 to January 2012. According to the way of operation, these patients were divided into two groups （cVATS group and thoracotomy group）. In the thoracotomy group, there were 62 patients （28 males and 34 females with an age of 46.2±11.9 years） who underwent routine thoracotomy lobectomy. In the cVATS group, there were 53 patients （19 males and 34 females with an age of 45.7±12.2 years） who underwent cVATS lobectomy. Operation time, intra-operative blood loss, postoperative thoracic drainage, complications and hospitalization, and cost of hospitalization were compared between the two groups. Results There was no perioperative death in all patients. There was no statistical difference in operation time between the two groups. Intra-operative blood loss of thoracotomy group patients was significantly higher than that of cVATS group patients （228.8±121.7 ml vs. 157.1±123.8 ml, t=2.592, P=0.011）. Postoperative thoracic drainage （866.7±439.5 ml vs. 1 805.3±466.7 ml, t=9.003，P=0.000）, duration of chest tube drainage （6.6±3.3 d vs. 9.8±4.6 d,t=3.339，P=0.001）, and postoperative hospitalization （7.5±2.2 d vs. 11.2±5.4 d, t=3.424，P=0.001） of cVATS group were significantly lower than those of thoracotomy group. The cost of hospitalization of cVATS group was significantly higher than that of thoracotomy group （38 543.6±11 051.8 yuan vs. 30 523.4±10 028.5 yuan，t=3.423, P=0.001）. There was no statistical difference in postoperative complications between the two groups （P＞0.05）. Forty-five patients in cVATS group were followed up for 2 to 14 months. Among them, 42 patients completely had no sputum or haemoptysis and 3 patients still intermittently had some sputum. Conclusion cVATS lobectomy is safe and feasible for the treatment of bronchiectasis. Compared with routine thoracotomy lobectomy, cVATS lobectomy does not increase surgical risk, but can significantly reduce operation injury and length of hospital stay. During cVATS, the lung residual should be handled cautiously especially for patients with nonanatomic pulmonary resection, and the non-single-order operation is recommended.
Objective To investigate the clinical significance of low dose corticosteroid applied in early period after lung volume reduction surgery（LVRS）. Methods From Apr. 2001 to Mar. 2004, 27 patients with chronic obstructive pulmonary disease were undergone video-assisted unilateral LVRS assisted with mini-incision in our department were retrospectively reviewed. According to whether dispensed with postoperative corticosteroid or not, patients were divided into corticosteroid group and non-corticosteroid group. Corticosteroid group received dexamethasone 10mg iv tid for 3 days and then declined to prednisone 5mg qd for 7 days. Both groups were measured and compared the quantity of thoracic drainage flow, duration of chest tube drainage, the time of air leaks and fever, and so on. At same time, blood gas analysis and blood routine test were performed at 1, 3, 7 and 30 d after operation. Results Corticosteroid and non-corticosteroid groups had no statistically differences in the air leaks time （P 〉 0.05）, but the quantity of thoracic drainage flow of corticosteroid group was lower than that of non-corticosteroid group evidently （700±210ml vs. 950±150ml, P = 0.001）. There was significant difference in average duration of chest tube drainage between both groups （9±3 d vs. 12±2 d, P = 0. 05）. Compared with non-corticosteroidgroup, PaO2 of corticosteroid group was higher at 1, 3d after operation （P〈0.05）. The amount of blood leukocyte of corticosteroid group was lower than that of non-corticosteroid group at 3, 7d after operation, there was no statistically significant in two groups （P 〉 0. 05）. At early period after surgery, both groups had no significant infection and death patient. Conclusion The low dose corticosteroid applied in early period after LVRS for short time（10 days in this research） could shorten the duration of chest tube drainage, decrease the quantity of thoracic drainage flow and the extent of inflammation in pleural cavity. In the mean time, this treatment does not increase the occurrence of significant complications during the early postoperative period, and there is no negative influence to the blood gas analysis.
Objective To investigate the surgical procedure selection, operation technique and safety of anatomic sublobar resection for pulmonary nodules. Methods The clinical data of 242 patients with clinical stage ⅠA lung cancer who underwent anatomic sublobar resection in our hospital between 2017 and 2020 were retrospectively analyzed. There were 81 males and 161 females with a median age of 57.0 (50.0, 65.0) years. They were divided into 4 groups according to the surgical methods, including a segmentectomy group (n=148), a combined segmentectomy group (n=31), an enlarged segmentectomy group (n=43) and an anatomic wedge resection group (n=20). The preoperative CT data, operation related indexes and early postoperative outcomes of each group were summarized. Results The median medical history of the patients was 4.0 months. The median maximum diameter of nodule on CT image was 1.1 cm, and the consolidation/tumor ratio (CTR) was ≤0.25 in 81.0% of the patients. A total of 240 patients were primary lung adenocarcinoma. The median operation time was 130.0 min, the median blood loss was 50.0 mL, the median chest drainage time was 3.0 d, and the hospitalization cost was (53.0±12.0) thousand yuan. The operation time of combined segmentectomy was longer than that of the segmentectomy group (P=0.001). The operation time (P=0.000), intraoperative blood loss (P=0.000), lymph nodes dissected (P=0.007) and cost of hospitalization (P=0.000) in the anatomic wedge resection group were shorter or less than those in the other three groups. There was no significant difference in the drainage time, total drainage volume, air leakage or postoperative hospital stay among the four groups (P>0.05). Conclusion The combined application of segmentectomy and wedge resection technique provides a more flexible surgical option for the surgical treatment of early lung cancer with ground glass opacity as the main component.
Objective To study the correlation of preoperative hemoglobin amount with venous thromboembolism (VTE) after surgical treatment of bronchiectasis and the clinical significance. Methods A retrospective study was performed on patients with bronchiectasis who underwent surgical treatment in our center from June 2017 to November 2021. The differences in blood parameters between the VTE patients and non-VTE patients were compared. The relationship between preoperative hemoglobin and VTE was confirmed by quartile grouping and receiver operating characteristic (ROC) curve. Results A total of 122 patients were enrolled, including 50 males and 72 females, with a mean age of 52.52±12.29 years. The overall incidence of VTE after bronchiectasis was 9.02% (11/122). Preoperative hemoglobin amount (OR=0.923, 95%CI 0.870-0.980, P=0.008) and D-dimer amount (OR=1.734, 95%CI 1.087-2.766, P=0.021) were independent influencing factors for VTE after bronchiectasis. The incidence of VTE after bronchiectasis decreased gradually with the increase of preoperative hemoglobin amount. The area under the ROC curve (AUC) of postoperative D-dimer alone was 0.757, whereas the AUC of postoperative D-dimer combined with preoperative hemoglobin amount was 0.878. Conclusion Low preoperative hemoglobin is an independent risk factor for postoperative VTE. Postoperative D-dimer combined with preoperative hemoglobin amount has a better predictive performance compared with postoperative D-dimer alone for postoperative VTE.
