Nonintubated video-assisted thoracic surgery (VATS) strategies are gaining popularity. This review focuses on noninutbated VATS, and discusses advantages, indications, anesthetic techniques, and approaches to intraoperative crisis management. Advances in endoscopic, endovascular, and robotic techniques have expanded the range of surgical procedures that can be performed in a minimally invasive fashion. The nonintubated thoracoscopic approach has been adapted for use with major lung resections. The need for general anesthesia and endotracheal intubation has been reexamined, such that regional or epidural analgesia may be sufficient for cases where lung collapse can be accomplished with spontaneous ventilation and an open hemithorax.

BACKGROUND: To address the feasibility and advantages of subxiphoid uniportal video-assisted thoracoscopic surgery (VATS) for lobectomy. METHODS: Since August 2014, 105 cases of subxiphoid uniportal VATS lobectomy were successfully performed. The clinical information was retrospectively analyzed. RESULTS: 96 cases underwent unilateral operation and 9 underwent bilateral operations. Surgeries were successfully performed with a complication rate of 10.5%. The average pain scores 8 hours, day 1, 2 and 3 after surgery, as well as the day before discharge were 2.39±0.99, 2.06±0.85, 1.68±0.87, 1.29±0.78, and 0.48±0.51, respectively, which were significantly lower than those in the control group (standard intercostal uniportal VATS) (P<0.001). CONCLUSIONS: The subxiphoid uniportal VATS lobectomy is safe and reliable, which is appropriate for bilateral lung diseases, and significantly relieves postoperative incision pain.
ABSTRACT
Background Broncholithiasis is a rare disease with various clinical classifications. The aim of this study was to evaluate the imaging diagnosis and surgical treatment of broncholithiasis. Methods and Materials Forty-eight patients with broncholithiasis were enrolled in this retrospective study between January 1985 and December 2009. Patients were classified into intraluminal, transluminal, and extraluminal broncholith according to the anatomy between the calculus and the bronchial lumen confirmed by chest computed tomography (CT), bronchoscopy, and pathology after operation. Result Forty-eight patients were enrolled, with 33 males and 15 females. The sex ratio (male:female) was 2.2:1, and average age was 54.3 ± 13.6 years. There were 8, 19, and 21 patients in intraluminal, transluminal, and extraluminal broncholith group, respectively. Cough, hemoptysis, and chest pain were the most common symptoms. Four patients with intraluminal broncholith and two with transluminal broncholith underwent broncholith removal via bronchoscopy, and the other 42 patients underwent thoracotomy. Conclusion Bronchoscopy combined with CT examination is helpful in diagnosing and typing broncholithiasis. An optimal treatment method, either bronchoscopic removal of broncholithiasis or thoracotomy, according to the clinical typing and indications, is the key to improve the treatment effect.

The association between common variations (rs10937405, rs4488809) on 3q28 and lung cancer has been widely evaluated in various ethnic groups, since it was first identified through genome-wide association approach. However, the results have been inconclusive. To derive a more precise estimation of the relationship and the effect of factors that might modify the risk, we performed this meta-analysis. The random-effects model was applied, addressing heterogeneity and publication bias. A total of 10 articles involving 36,221 cases and 58,108 controls were included. Overall, the summary per-allele OR of 1.19 (95 % CI 1.14-1.25, P < 10(-5)) and 1.17 (95 % CI 1.10-1.23, P < 10(-5)) was found for the rs10937405 and rs4488809 polymorphisms, respectively. Significant results were also observed in heterozygous and homozygous when compared with wild genotype for these polymorphisms. Significant results were found in East Asians when stratified by ethnicity, whereas no significant associations were found among Caucasians. After stratifying by sample size, study design, control source and sex, significant associations were also obtained. In addition, our data indicate that these polymorphisms are involved in lung cancer susceptibility and confer its effect primarily in lung adenocarcinoma when stratified by histological subtype. Furthermore, significant associations were also detected both never-smokers and smokers for these polymorphisms. In conclusion, this meta-analysis demonstrated that rs10937405 and rs4488809 are a risk factor associated with increased non-small cell lung cancer susceptibility, particularly for East Asian populations.

OBJECTIVE: This study aims to demonstrate our surgical experience for bronchiectasis and analyze the risk factors related with the surgery outcome. METHODS: We retrospectively reviewed medical records of 260 consecutive patients who underwent surgery for bronchiectasis between January 2000 and December 2010. The factors related with the outcome were analyzed and the candidate factors were screened by χ(2) test and t test. Furthermore, logistic regression analysis was used for multiple factor analysis to obtain the independent factors that affected the surgical outcome. RESULTS: Complications occurred in 30 (11.5%) patients during perioperative period. The univariate analysis showed that significant differences can be observed in age (P = 0.000), sputum volume (P = 0.000), smoking history (P = 0.033), pulmonary function (P = 0.003), Gram-negative bacillus infection (P = 0.000), bronchial stump coverage (P = 0.016) using intercostals muscles or pedicle pleura embedding and surgical approach (P = 0.003) between the patients with excellent and poor outcome. The multivariable analyses showed that sputum volume (P = 0.000), Gram-negative bacillus infection (P = 0.000) and bronchial stump coverage (P = 0.000) were the three independent factors related with surgical outcome. CONCLUSION: Surgery is an effective treatment option for bronchiectasis. Sputum volumes lower than 30 mL, negative proof of Gram-negative bacteria and bronchial stump coverage using intercostals muscles or pedicle pleura embedding are the key factors for successful treatment. Special attention has to be given to any complications in elderly patients.

Genome-wide association studies have identified two SNPs (rs402710 and rs401681) of CLPTM1L at chromosome 5p15.33 as a new lung cancer (LC) susceptibility locus in populations of European descent. Since then, the relationship between these SNPs and LC has been reported in various ethnic groups; however, these studies have yielded inconsistent results. To investigate this inconsistency, we performed a meta-analysis of 27 studies involving a total of 60,828 cases and 109,135 controls for the two polymorphisms to evaluate its effect on genetic susceptibility for LC. An overall random-effects per-allele odds ratio of 1.14 (95% CI 1.11-1.16, P < 10(-5)) and 1.15 (95% CI 1.12-1.19, P < 10(-5)) was found for the rs401681 and rs402710 polymorphism, respectively. Significant results were also observed for under dominant and recessive genetic models. After stratified by ethnicity, significant associations were found among Caucasians and East Asians. In the subgroup analysis by sample size, significantly increased risks were found for these polymorphisms in all genetic models. In addition, we find both rs402710 and rs401681 conferred significantly greater risks for adenocarcinoma and squamous cell carcinoma when stratified by histological type of tumors. Furthermore, associations of these polymorphisms with LC risk were observed among current smokers and former smokers, as well as never smokers. Our findings demonstrated that rs402710 and rs401681 are risk-conferring factors for the development of lung cancer.

OBJECTIVES: Station 3A nodes have been commonly neglected in surgical practice. This retrospective study collected information on the incidence and risk factors of Station 3A node to ascertain the prognostic role of 3A nodal involvement. METHODS: A total of 180 consecutive pN2 (stage IIIa) non-small-cell lung cancer (NSCLC) cases who underwent systemic lymphadenectomy and contained Station 3A nodes were enrolled. Survival rates were calculated according to the final pathology of Station 3A lymph node: Station 3A node (+) and Station 3A node (-). Statistical analysis was conducted using Kaplan-Meier and Cox regression models. RESULTS: Station 3A nodal metastasis was validated in 32 cases, and the incidence of Station 3A node involvement was 17.8%. Station 3A nodes involvement was strongly associated with the metastatic status of Station 4R nodes and histological nature of pulmonary cancer. The overall 3-year survival was 53% and median survival time was 40.6 months. The 3-year survival difference was significant between Station 3A node (-) and Station 3A node (+) (63 vs 22%, χ(2) = 16.426, P < 0.001). Moreover, the overall 3-year survival was closely related with the number of involved nodal zones (χ(2) = 31.156, P < 0.001). Multivariate analysis showed two statistically significant risk factors for survival including metastasis of Station 3A node and the number of positive nodal zones (hazard ratios [HR]: 2.702; 95% confidence intervals [CI]: 1.008-7.242; P = 0.027; and HR: 7.404; 95% CI: 3.263-16.936, P < 0.001, respectively). CONCLUSIONS: The involvement of Station 3A lymph nodes predicts poor prognosis of right-sided stage pIIIa-N2 NSCLC patients. Therefore, systemic lymphadenectomy for right-sided cancers should include Station 3A nodes when ascertaining a complete resection.

OBJECTIVE: To clarify the clinical feature, diagnosis and therapy of the pulmonary cryptococcosis (PC). METHODS: A retrospective study of cases with PC who were diagnosed by pathological examinations between January 1996 and December 2010 was conducted. Eighty-one cases were enrolled in the study (58 male and 23 female patients; mean age of (51±11) years). Forty-one cases were asymptomatic at the time of diagnosis. There were single pulmonary lesions in 50 cases, and multiple lesions in 31 cases. Fourteen lesions (17.3%) were located in left upper lobe, 27 (33.3%) in left lower lobe, 21 (25.9%) in right upper lobe, 3 (3.7%) in right middle lobe, 28 (34.6%) in right lower lobe, and 3 (3.7%) diffusely involved bilateral lungs. The tumors ranged from 0.8 to 10.0 cm in diameter with a mean of (2.9±1.8) cm. All the cases were misdiagnosis prior to the surgical resection, and histologically confirmed by postoperative pathological specimens. RESULTS: All the cases received surgical treatment including complete resection in 69 cases, and palliative resection in 12 cases. Resections were performed by means of video-assisted thoracoscopy in 31 cases and thoracotomy in 50 cases. Surgical resections included pulmonary wedge excisions in 42 cases, and lobectomies in 39 cases. After histological confirmation, 63 cases (77.8%) were treated with antifungal agents, which consisted of fluconazole in 38 cases, itraconazole in 18 cases, amphotericin B in 6 cases, and flucytosine in 4 cases. There were no intraoperative death, but two cases died for cryptococcal meningoencephalitis in the postoperative period. Operative morbidity occurred in 7 (8.6%) cases. The median follow-up was 42.5 months (6 to 84 months). There were 2 local relapses of PC, and 9 cases with complications of anti-fungal agents. CONCLUSIONS: The clinical manifestations of PC are mild and non-specific, with no characteristic radiographic manifestations. Surgical resection is usually indicated for definite diagnosis and treatment. Antifungal drug therapy is indispensable even after complete resection.

OBJECTIVE: To investigate the clinicopathological features and surgical treatment of pulmonary sclerosing hemangioma (PSH). METHODS: Clinic data of PSH patients admitted by surgical resection from January 1985 to December 2010 was analyzed retrospectively. One hundred and sixty-five patients were enrolled in the study. There were 27 male and 138 female patients with a mean age of (48 ± 13) years. Seventy-nine patients were asymptomatic at the time of diagnosis. Eighty-nine tumors arose in the right lung (27 in right upper lobe, 24 in right middle lobe, 34 in right lower lobe, 2 in right upper lobe with invasion of right middle lobe, 1 in right middle lobe with invasion of right lower lobe, and 1 case with multiple lobe lesions), 75 in the left (33 in left upper lobe, 42 in left lower lobe), and 1 in the bilateral. There were huge mass lesions in 2 cases, endobronchial lesions in 2 cases, and multiple lesions in 6 cases. The mean size of the lesion was (2.6 ± 0.9) cm (ranging from 0.9 to 10.0 cm). Forty-eight cases (29.1%) were misdiagnosed as malignancies preoperatively, and 41 cases (24.8%) were misdiagnosed intraoperatively. RESULTS: Resections were performed by means of video-assisted thoracoscopy (n = 53) and thoracotomy (n = 112). Surgical resection included pulmonary wedge excision in 61 patients, lobectomy in 89 patients, right bilobectomy in 5 patients, anatomic segmentectomy in 2 patient, enucleation in 6 patients, and synchronous bilateral pulmonary wedge resection in 1 patient. Operative mortality and morbidity occurred in 0 and 2 (4.3%) patients, respectively. Mean follow-up was 34.7 months (ranging from 6 to 62 months). There was no local recurrence or death from PSH. CONCLUSIONS: PSH is a rare benign lung tumor. It is difficult to make accurate diagnosis preoperatively, and sometimes even intraoperative frozen sections can't differentiate it from malignant tumors. Surgical resection is usually indicated for definite diagnosis and treatment. Partial resection is a sufficient treatment in view of uncommon tumor recurrence. Thoracoscopic surgery is recommended for PSH.

The surgical treatment of pulmonary aspergilloma is challenging and controversial. This study was designed to evaluate the clinical profile, indications and surgical outcomes of pulmonary aspergilloma operated on in our institute. A total of 256 patients with pulmonary aspergilloma underwent surgical treatment from 1975 to 2010. The patients were divided into two groups: Group A (simple aspergilloma, n = 96) and Group B (complex aspergilloma, n = 160). The principal underlying lung disease was tuberculosis (71.1%). The surgical procedures consisted of 212 lobectomies in both groups; eight cavernoplasties, 10 bilobectomies, 16 pneumonectomies and six thoracoplasties in Group B; four segmentectomies and six wedge resections in Group A. Postoperative complications occurred in 40 patients (15.6%). The major complications were residual pleural space (3.9%), prolonged air leak (3.1%), bronchopleural fistula (1.6%), excessive bleeding (1.6%), respiratory insufficiency (1.9%) and empyema (1.2%). No intraoperative deaths occurred. The overall mortality within 30 days post-operation was 1.2%, occurring only in Group B. There was no statistically significant difference in the postoperative morbidity between Groups A and B (P = 0.27). With the good selection of patients, meticulous surgical techniques and good postoperative management, aggressive surgical treatment with anti-fungal therapy for pulmonary aspergilloma is safe and effective, and can achieve favourable outcomes.

PURPOSE: To investigate the prognostic role of radical lymph node dissection in treatment for pulmonary Low Grade Malignant Tumors (LGMTs); specifically, on the extent of nodal removal and its impact on long-term survival. METHODS: A total of 93 LGMTs cases underwent surgical resection and were histopathologically confirmed. Overall survival rates and disease-free survival were respectively calculated according to the extent of lymph node resection and histopathological grades of tumors. Risk factors of nodal involvement and survival predictors were calculated via multivariate analysis. Life table, Kaplan-Meier, and Cox regression models were used for the statistical analysis. RESULTS: Thirty-eight cases of carcinoid, 17 adenoid cystic carcinomas, and 38 mucoepidermoid carcinomas were included in the current study. Twenty-one cases were high-grade and 72 were low-grade. A total of 813 lymph nodes were removed, at an average of 8.7±5.4 nodes per patient. The numbers of harvested nodes were 11.8±4.5, in the study group via radical nodal removal and 4.0±2.4 nodes per patient in the nodal sampling group. Eleven cases showed lymph nodal involvement (5 mediastinal and 6 hilar lymph node metastasis). No significant differences of overall survival was found among the different histological types (p=0.939), or the extent of nodal removal (p=0.971). Meanwhile, there was a significant difference of disease-free survival (DFS) rates according to the extent of nodal removal (5-YS: 97% of radical nodal dissection vs. 78% of nodal sampling, p=0.038). Overall survival and disease-free survival were closely associated with histological grading (OS: 78% of high grade vs. 97% of low grade, p=0.001; DFS: 57% of high grade vs. 97% of low grade, p<0.0001). CONCLUSIONS: Radical lymph node dissection improved disease-free survival for pulmonary low-grade malignant tumors, although no obvious improvement on overall survival was noticed. Histological grade was the most important prognostic factor in LGMTs.

BACKGROUND: The prognostic significance of hilar structures invasion, which remains undefined for non-small cell lung cancer (NSCLC), may have potential application for cancer staging. Tumor extension along the bronchus and pulmonary vessels was examined for survival significance. METHODS: In all, 213 pathologically proved central-type stage I NSCLC cases were enrolled. Four study groups were assigned based on the extent of resections: standard lobectomy (group L, n=32), bronchoplastic procedures (group B, n=94), standard lobectomy combined with pulmonary angioplasty (group A, n=48), and bronchial sleeve resection combined with pulmonary artery angioplasty (group BA, n=39). Univariate and multivariate analysis were performed by the Kaplan-Meier method and the Cox regression model. RESULTS: There were 2 postoperative deaths (pulmonary embolism and serious pulmonary infection). Complications were noted in 39 patients (18.3%). Among these patients, the overall 5-year survival rate was 60.2%±0.05%, with a median survival time of 75.0±7.5 months. The 5-year survival rates of subgroups were 79.5%, 59.7%, 59.0%, and 47.9%, respectively for groups L, B, A, and BA. Univariate analysis indicated tumor size, bronchial invasion, arterial involvement, and type of operation as closely associated with long-term survival. Multivariate analysis indicated that type of operation and tumor size were the most prominent prognostic factors of 5-year survival. CONCLUSIONS: Proximal tumor extension into bronchus, invasions into extrapericardial pulmonary vessels, and tumor size were the most important risk factors for 5-year survival with central-type stage I NSCLC. Tumor extension in the hilum was highly related to prognosis and might provide pertinent information to accurately define a tumor ("T") subclass.

PURPOSE: N2 non-small-cell lung cancer (NSCLC) is a heterogeneous disease with an extremely wide range of 5-year survival rates. A composite method of sub-classification for N2 is likely to provide a more accurate method to more finely differentiate prognosis of N2 disease. METHODS: A total of 720 pN2 (T1-4N2M0) NSCLC cases were enrolled in our retrospective analysis of the proposed composite method. Survival rates were respectively calculated according to the N2 stratification methods: singly by "nodal stations", "nodal zones", or "nodal chains", or by combination of all three. Statistical analysis was carried out by Kaplan-Meier and Cox regression models. RESULTS: A total of 10,199 lymph nodes (8059 mediastinal; 2140 hilar and intra-lobar) were removed. By nodal station, there were 173 cases of single-station involvement and 547 multi-stations. By nodal zone, there were 413 single-zone involvement and 307 with multiple zones. By nodal chain, there were 311 cases with single-chain and 409 multi-chain involvements. The overall 5-year survival was 20% and median survival time was 27.52 months. The 5-year survival was significantly better for cases of single-zone involvement, as compared to multi-zones (29% vs. 6%, p<0.0001). The 5-year survival rates of single- and multi-chains involvement were 36% and 8%, respectively (p<0.0001). When taking all of the above grouping methods into consideration, the N2 disease state could be further sub-classified into two subgroups with respective survival rates of 36% and 7% (p<0.0001). Subgroup I was composed of individuals with single-chain involvement and having either one or two station metastasis; individuals with any other metastasis combinations formed Subgroup II. Multivariate analysis revealed that the composite sub-classification method, number of positive lymph nodes, ratio of nodal metastasis, and pT information were the most important risk factors of 5-year survival. CONCLUSIONS: By combining the three N2 stratification methods based on "stations", "zones", and "chains" into one composite method, prognosis prediction was more accurate for N2 NSCLC disease. Single nodal chain involvement, which may be either one or two nodal stations metastasis, is associated with best outcome for pN2 patients.

BACKGROUND: Lung transplantation (LT) is a viable option for patients with end-stage lung diseases, but in China, the supply is limited, and the experience with LT is rare too. This study aimed to evaluate the survival and postoperative complications of recipients undergone LT. METHODS: From January 2003 to May 2010, all patients who underwent LT were included. The clinical data of recipients were analyzed retrospectively, including demographic characteristics, survival rate, and the occurrences of postoperative complications, acute rejection and bronchiolitis obliterans syndrome. RESULTS: In total, 37 patients underwent LT. The early mortality (≤ 30 days) was 14% (5/37). Cumulative survival rate was 78%, 70%, 70% and 42% at 1, 3, 5 and 6 years, respectively. In 37 patients, 5 (14%) developed fungal infections, 9 (24%) pulmonary bacterial infections, and 6 (16%) had bronchial anastomosis complications after LT. At three months post-transplantation, a significant improvement was observed in lung function (P < 0.05). Fifteen recipients (41%) developed acute rejection within the first year. Freedom from bronchiolitis obliterans syndrome was 89%, 85% and 80% at 1, 2 and 3 years after transplantation. CONCLUSIONS: Despite the limited number of cases, the survival and occurrences of complications after LT were comparable to the international experience. Single LT may be a reasonable option for some patients with end-stage pulmonary diseases.

PURPOSE: Present research aimed to explore the rationale of defining RIR operations by metastatic status of highest nodes. PATIENTS AND METHODS: 549 surgical patients, bearing pN2-NSCLCs, were enrolled in the current study. R1/R2 nodes on the right side and L4 nodes on the left were taken as the highest mediastinal lymph nodes. The operations were defined "Complete Resection (CR)" if the highest nodes were negative. Operations were otherwise "Relative Incomplete Resections (RIR)" if the nodes were positive. Exclusion criteria included: metastatic carcinomas or small cell lung cancer, prior history of induction therapy, exploratory thoracotomy, palliative resection, and massive pleural dissemination, as well as cases without "highest" mediastinal nodal pathology. The survival rate was calculated using the life-table and Kaplan-Meier method. Comparisons between groups were calculated using the Log-rank test. RESULTS: A total of 6865 lymph nodes (5705 mediastinal and 1160 regional, average 12.6±6.4 nodes for each patient) were removed. Total cases included 246 RIR (100 left and 146 right side) and 303 CR (108 left and 195 right). The overall 5-year survival rate was 22% and the median survival time was 28.29 months. Five-year survival rates of the CR and RIR group were statistically significant (29% and 13%, respectively p<0.0001). L4 and R1/R2 lymph nodes had similar position for defining RIR; no obvious survival difference was indicated between either side (p=0.464 in CR groups, p=0.647 in RIR groups). N2 subcategories and skip-metastasis were closely associated with highest nodal involvement (p<0.0001). Multivariate analysis showed CR/RIR assignment, tumor size, N2 disease stratification, pathological T status, and number of positive mediastinal nodes were risk factors for 5-year survival in the present case series. CONCLUSION: Involvement of the highest mediastinal lymph nodes is highly predictive of poor prognosis and indicates an advanced stage of the disease. Therefore, it may be appropriate to assign R1/R2 or L4 as criterion for defining RIR or CR cases in surgical NSCLC cases.

OBJECTIVE: To compare video-assisted thoracic surgery (VATS) and open thoracotomy (OT) on acute inflammatory responses and immunosuppression after lobectomy for early non-small cell lung cancer (NSCLC). METHODS: Present prospective randomized study. OT or VATS lobectomy was performed in patients who met enter criteria and clinical data was collected. Plasma concentration of IL-6, IL-8 and IL-10 were measured before surgery and at postoperative day (POD) 1 and POD 3. There were 271 patients underwent lobectomy for early NSCLC, including of 133 patients in group VATS and 138 patients in group OT from January 2007 to June 2008. There were 132 males and 139 females, aging from 19 â¼ 70 years with a mean of (56 ± 8) years. RESULTS: Compared with OT group, shorter postoperative hospital stay [(8.2 ± 2.5) d vs. (9.8 ± 6.2) d, P = 0.03], lower morbidity rate (11.3% vs. 21.7%, P = 0.02) and lower increase of plasma concentration of IL-6 at POD 1 [(35 ± 25)% vs. (65 ± 43)%, P = 0.00], IL-6 at POD 3 [(14 ± 22)% vs. (55 ± 44)%, P = 0.00] and IL-10 at POD 1 [(25 ± 20)% vs. (43 ± 35)%, P = 0.00] were observed in patients of VATS group. CONCLUSION: VATS lobectomy for early NSCLC is associated with less acute inflammatory responses and less immunosuppression when compared with OT.

We describe a technique used in a patient for resection of adenoid cystic carcinoma arising from the left main bronchus and extending along the lateral wall of the lower trachea without carinal invasion. A flap was mobilized from the noninvolved lateral wall of the left main bronchus, which was left attached to the carina. This was used to close the defect in the lower trachea with the implantation of the left main bronchus, avoiding a tracheal sleeve pneumonectomy. Clinical course of this case was good. The pedicled autologous bronchial flap provides reliable material to repair and reconstruct a massive central airway defect.
