OBJECTIVETo investigate the operation of lung transplantation for end-stage emphysema.

METHODSFrom September 2002 to February 2005, 9 patients with chronic obstructive pulmonary disease (COPD) underwent lung transplantation. The types of surgery included single lung transplantation in 2 patients, lung transplantation with asynchronous contralateral lung volume reduction (one week later) in 1, single lung transplantation with synchronized contralateral lung volume reduction in 4, and bilateral sequential lung transplantation without cardiopulmonary bypass in 2.

RESULTSThe volume of chest drainage was more than 2000 ml at the first postoperative day in 2 patients, one was reoperated for hemostasis and another was successfully responded to conservative therapy. The ventilation time was ranged from 3 to 22 days postoperatively. Two patients were received tracheotomy. Seven patients achieved good results, two of them had returned to work, and 1 patient had lived for 30 months. One patient was died of severe acute rejection (4A) at 15th postoperative day and 1 succumbed to multisystem organ failure due to severe bacterial infection combine fungal infection.

CONCLUSIONEnd-stage emphysema is an indication for single lung transplantation. Single lung transplantation with contralateral lung volume reduction is a good way to utilize donor. If patient suffered from infection, double-lung transplantation should be considered first.

Voluntary contribution has become the only source of donor lungs in China since 2015. To elaborate the outcomes of patients awaiting lung transplantation (LTx) after the implementation of donation after brain death, we performed a retrospective study that encompassed 205 patients with end-stage lung disease who registered for LTx at Shanghai Pulmonary Hospital from January 1, 2015 to January 1, 2021. A total of 180 patients were enrolled in the study. The median waiting time was 1.25 months. Interstitial lung disease (ILD) (103/180, 57.2%) and chronic obstructive pulmonary disease (COPD) (56/180, 31.1%) were the most common diseases in our study population. The mean pulmonary artery pressure (mPAP) of patients in the died-waiting group was higher than that of the survivors (53.29±21.71 mmHg vs. 42.11±18.58 mmHg, P=0.002). The mortality of patients with ILD (34/103, 33.00%) was nearly twice that of patients with COPD (10/56, 17.86%) while awaiting LTx (P=0.041). In the died-waiting group, patients with ILD had a shorter median waiting time than patients with COPD after being listed (0.865 months vs. 4.720 months, P=0.030). ILD as primary disease and mPAP > 35 mmHg were two significant independent risk factors for waitlist mortality, with hazard ratios (HR) of 3.483 (95% CI 1.311-9.111; P=0.011) and 3.500 (95% CI 1.435-8.536; P=0.006). Hence, LTx is more urgently needed in patients with ILD and pulmonary hypertension.

Objective To observe the effect of calcified lymph nodes on video-assisted thoracoscopic surgery (VATS) lobectomy in the chronic obstructive pulmonary disease (COPD) patients with lung cancer. Methods A retrospective analysis was conducted on the COPD patients with lung cancer who underwent VATS lobectomy in the Department of Thoracic Surgery in the First Affiliated Hospital of Hebei North University from May 2014 to May 2018.The patients were assigned into a calcified lymph node group and a control group according to the presence or absence of calcified lymph nodes in CT,and the size,morphology,and calcification degree of the lymph nodes were recorded.The operation duration,intraoperative blood loss,chest tube retention time,hospitalization days,and overall complication rate were compared between the two groups. Results The 30 patients in the calcified lymph node group included 17 patients with one calcified lymph node and 13 patients with two or more calcified lymph nodes,and a total of 65 calcified lymph nodes were recorded.The calcified lymph nodes with the size ≤5 mm were the most common (53.8%),and complete calcification was the most common form (55.4%) in lymph node calcification.The mean operation duration had no significant difference between the calcified lymph node group and the control group (t=-1.357,P=0.180).The intraoperative blood loss (t=-2.646,P=0.010),chest tube retention time (t=-2.302,P=0.025),and hospitalization days (t=-2.274,P=0.027) in the calcified lymph node group were higher than those in the control group. Conclusion Calcified lymph nodes increase the difficulty and risk of VATS lobectomy in the COPD patients with lung cancer.The findings of this study are conducive to predicting the perioperative process of VATS lobectomy.

BACKGROUND: Chronic obstructive pulmonary diseases (COPD) affects 45%-63% of lung cancer patients worldwide. Lung cancer patients complicated with COPD have decreased cardiopulmonary function and increased perioperative risk, and their postoperative exercise endurance and lung function are significantly lower than those with conventional lung cancer. Previous studies have shown that postoperative exercise training can improve the exercise endurance of unselected lung cancer patients, but it is unclear whether lung cancer patients with COPD can also benefit from postoperative exercise training. This study intends to explore the effects of postoperative exercise training on exercise endurance, daily activity and lung function of lung cancer patients with COPD. METHODS: Seventy-four patients with non-small cell lung cancer (NSCLC) complicated with COPD who underwent pneumonectomy in the lung cancer center of West China Hospital of Sichuan University from August 5, 2020 to August 25, 2021 were prospectively analyzed. They were randomly divided into exercise group and control group; The patients in the two groups received routine postoperative rehabilitation in the first week after operation, and the control group was given routine nursing from the second week. On this basis, the exercise group received postoperative exercise rehabilitation training for two weeks. Baseline evaluation was performed 3 days before operation and endpoint evaluation was performed 3 weeks after operation. RESULTS: The exercise endurance, daily activity and pulmonary function test results of the two groups decreased from baseline to the end point. However, after the operation and intervention program, the maximum oxygen consumption of Cardiopulmonary Exercise Test and the walking distance of 6-Minute Walking Test in the exercise group were significantly better than those in the control group [(13.09±1.46) mL/kg/min vs (11.89±1.38) mL/kg/min, P=0.033; (297±46) m vs (243±43) m, P=0.041]. The average number of we-chat steps in the exercise group was also significantly better than that in the control group (4,381±397 vs 3,478±342, P=0.035). Forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) in the exercise group were better than those in the control group, but the difference did not reach a statistically significant level [(1.76±0.19) L vs (1.60±0.28) L, P=0.084; (1.01±0.17) L vs (0.96±0.21) L, P=0.467]. CONCLUSIONS Postoperative exercise rehabilitation training can improve exercise endurance and daily activity ability of patients with lung cancer complicated with COPD and promote postoperative rehabilitation.

From March 1985 to June 1997, 451 patients of spontaneous pneumothorax treated at Kangbuk Samsung Hospital were reviewed retrospectively. Most of the patients were male (male to female ratio, 8.2:1). The mean age of the primary spontaneous pneumothorax (PSP) was 26.8 years, and that of secondary spontaneous pneumothorax (SSP) was 53.1 years. 330 out of 451 patients (73%) were PSP. The causes of the SSP were mostly pulmonary tuberculosis and COPD: 87 patients (72%), and 24 patients (19.2%), respectively. All the patient were treated by one of the following modalities: 1)rest and oxygen therapy in 42 patients, 2) closed thoracostomy in 208 patients, 3) thoracotomy in 156 patients, 4) VATS bullectomy in 45 patients. The mean duration of postoperative chest tube drainage was as following: thoracotomy 8.3 days, VATS bullectomy 4.7 days. For recent 3 consecutive years, VATS bullectomy has become the more frequently applied operative procedure than thoracotomy in the treatment of surgically indicated PSP, from 33% in 1994 to 78% in 1996. With the minimally invasive thoracoscopic surgery being more prevalent, VATS bullectomy will be able to be the 1st choice of treatment not only for the recurrent pneumothoracies but also for the some selected cases of the 1st episode pneumothoracies. To verify this approach as clinically acceptable one in terms of cost-effectiveness, recurrence rate, etc, a large scale of multi-institutional clinical study will be needed in a sooner time.

OBJECTIVETo assess the effect of radical laparoscopy-assisted gastrectomy(LG) for patients with chronic obstructive pulmonary disease (COPD).

METHODSClinical data of 340 gastric cancer patients with COPD undergoing radical gastrectomy with lymphadenectomy at Southwest Hospital, Third Military Medical University between January 2010 and October 2013 were analyzed retrospectively. The clinical outcomes for the 262 patients with COPD who underwent LG(LG group) were compared with those of 78 patients with COPD who underwent open gastrectomy(OG group). During LG, pneumoperitoneum was maintained at an insuffiation pressure of 8 mmHg to 10 mmHg. The primary endpoint was postoperative pulmonary complication(PPC). To predict factors related to PPC, univariate and multivariate logistic analyses were carried out.

RESULTSIntraoperative blood loss was significantly less in the LG group [(131.2±14.7) ml] than in the OG group [(246.7±49.0) ml; t=-13.445, P=0.000], but operation time was significantly longer [(220.4±19.1) min vs. (194.2±31.5) min; t=6.877, P=0.000]. The findings showed PPC to be significantly less frequent in the LG group(5.3%,14/262) than in the OG group (15.4%, 12/78)(χ(2)=8.581, P=0.003). The severity of COPD was independent risk factor for PPC(P=0.031, HR=1.456, 95%CI:1.306-1.789). No independent predictor of PPCs was found in type of operative approach (open vs laparoscopic; P=0.126).

CONCLUSIONThe LG procedure with insuffiation pressure of pneumoperitoneum is tolerated for gastric cancer patients with mild or moderate COPD.

OBJECTIVETo compare changes in early pulmonary function and hemodynamics between unilateral and bilateral lung volume reduction (LVRS) for severe chronic obstructive pulmonary disease (COPD).

METHODSEighty-six patients with severe COPD underwent LVRS, 61 underwent unilateral LVRS and 25 underwent lateral LVRS. The results of lung function (FEV(1), RV, TLC), arterial blood gas analysis (PaO(2), PaCO(2)) and color Doppler echocardiography (CO, CI, EF, PAP) were evaluated preoperatively and 3, 6 months postoperatively.

RESULTSSix patients died. FEV(1), RV and TLC were improved significantly after (P < 0.05). PaO(2) increased (P < 0.05) and PaCO(2) decreased postoperatively (P < 0.05). According to the Doppler echocardiography there were no statistic difference in cardia functions (CO, CI, EF, PAP) between unilateral and bilateral LVRS preoperatively and 3, 6 months postoperatively.

CONCLUSIONSUnilateral and bilateral LVRS is safe and effective in the treatment of patients with severe COPD, the pulmonary function significantly improved postoperatively, but the results of bilateral LVRS is better than unilateral. Both unilateral and bilateral LVRS showed no significant deterioration in hemodynamics, there were no significant difference between preoperatively and postoperatively.

BACKGROUNDNow lung volume reduction surgery (LVRS) has become one of the most effective methods for the management of some cases of severe chronic obstructive pulmonary disease (COPD). We evaluated the mid-term effects of LVRS on pulmonary function in patients with severe COPD.

METHODSTen male patients with severe COPD aged 38 - 70 years underwent LVRS and their pulmonary function was assessed before, 3 months and 3 years after surgery. The spirometric and gas exchange parameters included residual volume, total lung capacity, inspiratory capacity, forced vital capacity, forced expiratory volume in one second, diffusion capacity for CO, and arterial blood gas. A 6-minute walk distance (6MWD) test was performed.

RESULTSAs to preoperative assessment, most spirometric parameters and 6MWD were significantly improved after 3 months and slightly 3 years after LVRS. Gas exchange parameters were significantly improved 3 months after surgery, but returned to the preoperative levels after 3 years.

CONCLUSIONSLVRS may significantly improve pulmonary function in patients with severe COPD indicating for LVRS. Mid-term pulmonary function 3 years after surgery can be decreased to the level at 3 months after surgery. Three years after LVRS, lung volume and pulmonary ventilation function can be significantly improved, but the improvement in gas exchange function was not significant.
