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.
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.
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.
Lobectomy and systematic nodules resection has been the standard surgical procedure for non-small cell lung cancer (NSCLC). However, increased small-size lung cancer has been identified with the widespread implementation of low-dose computed tomography (LDCT) screening, and it is controversial whether it is proper to choose lobar resection for the pulmonary nodules. Numerous retrospective researches and randomized clinical trials, such as JCOG0201, JCOG0804/WJOG4507L, JCOG0802 and CALGB/Alliance 140503, revealed that the sublobar resection was safe and effective for NSCLC with maximum tumor diameter≤2 cm and with consolidation tumor ratio (CTR)≤0.25, and that segmentectomy was superior to lobectomy with significant differences in 5-year overall survival rate and respiratory function for patients with small-size (≤2 cm, CTR>0.5) NSCLC and should be the standard surgical procedure. It is the principle for multiple primary lung cancer that priority should be given to primary lesions with secondary lesions considered, and it is feasible to handle the multiple lung nodules based on the patients' individual characteristics.
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.
ObjectiveTo explore the effects of rehabilitation therapy on postoperative pulmonary function and exercise capacity of patients with lung cancer during the hospitalization in the setting of enhanced recovery after surgery (ERAS) protocols.MethodsA total of 110 lung cancer patients undergoing thoracoscopic lobectomy in the Department of Thoracic Surgery, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from September 2017 to December 2018 were randomly divided into the rehabilitation treatment group (the trial group, n=54) and the non-rehabilitation treatment group (the control group, n=56). The trial group got out of bed within 24 hours after surgery and performed respiratory rehabilitation training. The control group did not receive rehabilitation after surgery. Pulmonary function and 6-minute walking distance (6MWD) were evaluated preoperatively and prior to discharge in both groups to compare the differences in pulmonary function and exercise capacity between the two groups.ResultsThe preoperative forced vital capacity (FVC) in the trial group and the control group were (2.45±0.57) and (2.47±0.61) L, respectively; the forced expiratory volume in the first second (FEV1) were (2.29±0.55) and (2.22±0.55) L, respectively; 6MWD were (592±51) and (576±57) m, respectively; the differences between the two groups were not statistically significant (P>0.05). Prior to discharge, the FVC in the trial group and the control group were (1.43±0.36) and (1.19±0.33) L, respectively; FEV1 were (1.28±0.32) and (1.06±0.61) L, respectively; 6MWD were (264±43) and (218±37) m, respectively. The results of pre-discharge evaluation were significantly lower than those of preoperative evaluation (P<0.01). The pre-discharge FVC, FEV1, and 6MWD in the trial group were significantly superior to those in the control group (P<0.01).ConclusionIn the setting of ERAS protocols, postoperative rehabilitation therapy during hospitalizations can improve pulmonary function and promote the recovery of exercise capacity in lung cancer patients more effectively.
ObjectiveTo compare clinical results between single and double chest tube applications after lung cancer resection, and explore the role of single chest tube in postoperative fast track recovery. MethodNinety-three patients with lung cancer who underwent lobectomy between March and December of 2009 in West China Hospital of Sichuan University were included in this study. All the patients were divided into a single-tube group including 46 patients (39 males and 7 females) with their age of 58.4±9.5 years, and a double-tube group including 47 patients (32 males and 15 females) with their age of 58.2±9.0 years. Drainage amount, duration, postoperative hospital stay, and incidences of pneumothorax and pleural effusion after removal of chest tubes were compared between the 2 groups. ResultsThe percentage of patients undergoing complete video-assisted thoracic surgery (VATS) of the double-tube group was significantly higher than that of the single-tube group, and the percentage of patients undergoing thoracotomy of the double-tube group was significantly lower than that of the single-tube group (P < 0.05). Drainage amount of the double-tube group was significantly larger than that of the single-tube group (824.4±612.5 ml vs. 510.7±406.7 ml, P < 0.05). There was no statistical difference in drainage duration, postoperative hospital stay, the incidences of subcutaneous emphysema, pneumothorax, pleural effusion or re-insertion of chest drain between the 2 groups (P > 0.05). ConclusionClinical results of single chest tube is better than or equivalent to those of double chest tubes after lung cancer resection, and drainage duration of single chest tube application might be shorter.
Objective To make a survival analysis for the stage ⅠA non-small cell lung cancer patients who underwent lobectomy, segmentectomy or wedge resection and to discuss whether the segmentectomy and wedge resection can be used as a conventional operation. Methods The clinical data of 474 patients diagnosed with ⅠA non-small cell lung cancer from January 2012 to June 2015 in the First Affiliated Hospital of China Medical University were retrospectively anlyzed. There were 192 males and 282 females with a mean age of 60 years. Their sex, age, histological type, tumor size, surgical pattern, smoking, drinking, survival rate, disease-free survival rate, recurrence rate were compared. Results Disease-free survival rate of patients with wedge resection was significantly lower than that of the patients undergoing lobectomy and segmentectomy (P<0.05). When tumor diameter≤19 mm, the disease-free survival rate of patients with wedge resection was lower than that of patients with lobectomy (P=0.006) and segmentectomy (P=0.065). Disease-free survival rate of patients with tumor diameter of 20-<30 mm was significantly lower than that of patients with tumor diameter≤19 mm (P=0.026). Excluding patients with wedge resection, disease-free survival of the patients with lobectomy and segmentectomy and tumor diameter of 20-<30 mm was significantly lower than that of patients with tumor diameter≤19 mm (P=0.036). Patients with wedge resection had significant higher risk of local recurrence than that of patients undergoing lobectomy (P<0.001) and segmentectomy (P=0.002). Conclusion StageⅠA non-small cell lung cancer patients undergoing segmentectomy can obtain approximate survival and disease-free survival rate compared with those with lobectomy, especially in patients with tumor diameter≤19 mm. Pulmonary wedge resection as surgical treatment of lung cancer patients must be selected carefully according to the actual situation and surgical purposes.
ObjectiveTo evaluate the feasibility and clinical value of robot-assisted lobectomy through anterior approach.MethodsWe retrospectively analyzed the clinical data of 180 patients who underwent robot-assisted lobectomy through anterior approach in our hospital between April 2017 and February 2018. There were 97 males and 83 females, aged 59.5 (32.0-83.0) years. The clinical effects were analyzed.ResultsOne patient was transferred to thoracotomy due to tumor invasion of adjacent blood vessels and injury to the blood vessels, and there was no perioperative death. There were 8.5 (1.0-35.0) dissected lymph nodes for each patient. The median operation time was 120 (50-360) min, including robot Docking time 5 (1-23) min and robot operation time 65 (7-270) min. The median blood loss was 50 (5-1 500) mL, 132 (73.3%) patients had malignant tumors and median drainage time was 5 (2-30) d. The mean postoperative pain score was 3.4±0.7 points and the postoperative hospital time was 8 (2-32) d. At the median follow-up of 24 months, 11 patients developed recurrence and metastasis, and 3 died.ConclusionRobot-assisted lobectomy through anterior approach is a safe and convenient operation method, which is worthy of clinical application.
Surgery has remained the cornerstone of lung cancer therapy. Sleeve lobectomy, which is featured by not only the maximal resection of tumors but also the maximal preservation of functional lung parenchyma, has been proved to be a valid therapeutic option for the treatment of some centrally located lung cancer . Evidence points toward equivalent oncologic outcomes with improved survival and quality of life after sleeve resections compared with pneumonectomy. However, the postoperative morbidities and the long-term results after sleeve lobectomy remain controversial, especially in relation to nodal involvement and after induction therapy. With the development of technology, minimally invasive procedures have been performed more and more widely.
