Objective. The purposes of this study were to evaluate the feasibility, safety, and advantages of nonintubated video-assisted thoracoscopic surgery (VATS) under epidural anesthesia, by comparing with the performance of conventional approaches. Patients and methods. A total of 354 patients (245 men and 109 women) were recruited in this study. The surgical procedures included bullae resection, pulmonary wedge resection, and lobectomy. The anesthetic technique (epidural vs general) was selected randomly. Patients who underwent nonintubated VATS under epidural anesthesia comprised the intervention group, and patients who received VATS under general anesthesia with double lumen tube comprised the control group. Results. In total, 167 patients were included in the intervention group, and 180 patients were included in the control group. The 2 treatment groups of bullae resection showed significant differences in postoperative fasting time, duration of postoperative antibiotic use depending on the time when the white blood cells decreased to normal levels, and duration of postoperative hospital stay (P < .05). Nonintubated VATS is associated with a decreased level of inflammatory cytokines (P < .05). Conclusion. VATS under anesthesia with nontracheal intubation is safe and feasible, and has demonstrated advantages, including shorter postoperative fasting time, shorter duration of antibiotic use, and shorter hospital stay, compared with VATS under general anesthesia with double lumen tube.

OBJECTIVE To study one-lung respiration during VATS wedge resection of bullae and pulmonary nodules with nontracheal intubation, and to explore the changes of vital signs when patients return to two-lung ventilation. METHODS Twenty-two patients with normal cardiopulmonary function and absence of contraindications to epidural anesthesia were included in this study. VATS wedge resection of bullae or pulmonary nodules was performed. 0.5% Ropivacain was administrated for epidural anesthesia (T8-9), and 2 mL of 2% lidocaine was used for local anesthetic block of the intrathoracic vagus nerves. The BIS value was maintained between 50 and 70 by target-controlled infusion of propofol and remifentanil. Electrocardiogram (ECG), heart rate (HR), blood pressure (Bp), pulse oxygen saturation (SpO(2)), respiratory rate (RR), bispectral index (BIS) and urine volume were monitored. RESULTS None patients were converted to endotracheal intubation during anesthesia. MAP and SpO(2) after wound disclosure were stable (P>0.05), level of CVP significantly elevated, HR and RR increased (P<0.05), PaCO(2) increased gradually while PaO(2) remained stable. Fifteen minutes after wound closure, MAP, RR and SpO(2) returned to their pre-anesthesia levels, PH value gradually recovered, PaCO(2) tended to decrease and returned to normal one hour after wound closure. Physical agitation occurred in one case due to inadequate epidural anesthesia during skin incision. Cough before intrathoracic vagal blockade was noted in two cases (9.1%) because of lobe traction. CONCLUSIONS Nontracheal intubation is feasible in VATS wedge resection of bullae and pulmonary nodules. The patients are with stable intraoperative vital signs and none experiences hypoxemia; intraoperative hypercapnia is tolerable and transient, which can be improved quickly when bilateral lungs resume spontaneous respiration.

The purpose of this research was to study the roles of chloride intracellular channel protein 1 (CLIC1) and heat shock protein 27 (HSP27) in the clinical pathology of lung adenocarcinoma and to explore whether the expression of CLIC1 and HSP27 can be used as independent factors for the prediction of recurrence and prognosis after radical resection of lung adenocarcinoma. One hundred and three paraffin sections of lung adenocarcinoma tissues were collected, and the expression of CLIC1 and HSP27 was detected in these tumors using immunohistochemistry. The correlation of the expression of these two proteins with clinicopathological parameters and prognosis was statistically analyzed. In the 103 samples, the expression of HSP27 and CLIC1 was strongly positive in 61 (59.2%) and 49 cases (47.6%), respectively. Statistical analysis showed that the expression level of HSP27 did not significantly correlate with the patient’s age, sex, degree of tumor differentiation, T staging of tumors, and TNM staging of tumors (p > 0.05), whereas the expression of CLIC1 did significantly correlate with T staging of tumors (p = 0.029). Univariate analysis indicated that the patient’s ECOG score, T staging, N staging, TNM staging, and CLIC1 expression correlated with prognosis (p = 0.031, 0.001, 0.011, 0.013, and <0.001, respectively). Multivariate statistical analysis showed that age, T staging, and CLIC1 expression were independent associated factors for predicting the 5-year survival rate of patients (p = 0.026, 0.004, and <0.001, respectively). Age, T staging, and CLIC1 expression significantly correlated with the overall survival of post-operative lung adenocarcinoma patients. CLIC1 may be closely associated with the occurrence and development of lung adenocarcinoma and may be used as an effective marker for predicting the prognosis of this disease.

Background. The objectives of this study were to report the surgical techniques and clinical outcome of thoracoscopic half carina resection and thoracoscopic bronchial sleeve resection for central lung cancer. Methods. Between January 2011 and November 2012, 675 patients with lung cancer underwent radical surgery by thoracoscopy, and 49 (7.3%) underwent bronchial sleeve resection. Among 49 patients, 20 (41%) received thoracoscopic bronchial sleeve lobectomy. Perioperative variables and postoperative outcomes of these cases were analyzed to evaluate the technical feasibility and safety of this operation. Results. In one patient, right upper lung sleeve resection was combined with half-carinal resection and reconstruction. In another, right medial lung sleeve resection was combined with lower right dorsal segment resection. The average time of surgery was 239 ± 51 minutes (range = 142-330 minutes), and the average time of airway reconstruction was 44 ± 17 minutes (range = 22-75 minutes). The intraoperative blood loss averaged 207 ± 96 mL (range = 80-550 mL). The median postoperative hospital stay was 10 days (interquartile range = 8-12 days). Postoperatively, extubation was achieved in the recovery room without further need for mechanical ventilation. None of the patients developed anastomotic leak. Perioperative mortality was not observed. Conclusion. Thoracoscopic bronchial sleeve resection can be considered a feasible and safe operation for selected patients with central lung cancer. The complicated anastomosis technique of half carina resection was feasible.

OBJECTIVE To explore the feasibility and safety of complete video-assisted thoracoscopic surgery (C-VATS) under non-intubated anesthesia for the resection of anatomic pulmonary segments in the treatment of early lung cancer (T1N0M0), benign lung diseases and lung metastases. METHODS The clinical data of patients undergoing resection of anatomic pulmonary segments using C-VATS under non-intubated anesthesia in the First Affiliated Hospital of Guangzhou Medical University from July 2011 to November 2013 were retrospectively analyzed to evaluate the feasibility and safety of this technique. RESULTS The procedures were successfully completed in 15 patients, including four men and eleven women. The average age was 47 [21-74] years. There were ten patients with adenocarcinoma, one with pulmonary metastases, and four with benign lung lesions. The resected sites included: right upper apical segment, two; right lower dorsal segment, one; right lower basal segment, two; left upper lingular segment, three; left upper apical segment, one; left upper anterior apical segment, two; left upper posterior segment, one; left lower basal segment, one; left upper posterior and apical segments, one; and left upper anterior and apical segments plus wedge resection of the posterior segment, one. One case had intraoperative bleeding, which was controlled with thoracoscopic operation and no blood transfusion was required. No thoracotomy or perioperative death was noted. Two patients had postoperative bleeding without the need for blood transfusions, and were cured and discharged. The pathologic stage for all patients with primary lung cancer was IA. After 4-19 months of follow-up, no tumor recurrence and metastasis was found. The overall mean operative length was 166 minutes (range 65-285 minutes), mean blood loss 75 mL (range 5-1,450 mL), mean postoperative chest drainage 294 mL (range 0-1,165 mL), mean chest drainage time 2 days (range 0-5 days), and mean postoperative hospital stay 5 days (range 3-8 days). CONCLUSIONS Complete video-assisted throacoscopic segmentectomy under anesthesia without endotracheal intubation is a safe and feasible technique that can be used to treat a selected group of IA patients with primary lung cancer, lung metastases and benign diseases.

OBJECTIVE To explore the feasibility of complete video-assisted thoracoscopic surgery (c-VATS) following neoadjuvant therapy (chemotherapy, targeted therapy and radiotherapy, either alone or in combination) for the treatment of patients with non-small cell lung cancer (NSCLC). METHODS The clinical data of 43 NSCLC patients undergoing c-VATS following neoadjuvant therapy were retrospectively analyzed, including the preoperative functional indicators, staging, concurrent diseases, surgical techniques, operation time, number of lymph nodes dissected and postoperative drainage time and quantity, postoperative hospital stay, postoperative complications, and survival. RESULTS From January 2006 to March 2012, a total of 43 patients with stage IIA-IIIB NSCLC were included in this study (IIIA: 27 cases, 62.8%; IIIB: 11 cases, 25.6%), including 32 males (74.4%) and 11 females (25.6%). Forty-two patients were operated successfully, 28 underwent pulmonary lobectomies (including 9 bronchial sleeve resections), 5 had double lobectomies, 5 had wedge resections, and 4 had total pneumonectomies. Seven patients were referred to undergo Hybrid VATS (7/42, 16.7%). The mean length of the operation was 160.48±16.52 min (range, 130-180 min); the intraoperative blood loss was 253.57±117.08 mL; the number of lymph nodes dissected was 16.88±10.93; the postoperative drainage time was 1-7 d (mean: 2.62±0.96 d); and the postoperative hospital stay was 3-7 d (mean: 5.45±1.30 d). The incidence of postoperative complications was 9.5% (4/42), and the perioperative mortality was 2.4% (1/42). The 1-, 2-, and 3-year overall survival rates were 94%, 79%, and 65%, respectively. CONCLUSIONS c-VATS following neoadjuvant therapy is safe and feasible for the treatment of locally advanced NSCLC.

Jianxing He; Xin Xu; Manyin Chen; Shuben Li; Weiqiang Yin; Susheng Wang; Yingying Gu

Inflammatory myofibroblastic tumor is extremely uncommon in the trachea. Surgery is recommended when airway obstruction becomes evident. The surgical technique and material used for repairing a massive tracheal defeat is a challenge for the thoracic surgeon. We present a case of repair and reconstruction of a massive defect of the thoracic trachea and right mainstem bronchus with a pectoralis major myocutaneous flap after resection of an inflammatory myofibroblastic tumor. The myocutaneous flap provides reliable material to repair and reconstruct a massive central airway defect. This novel surgical procedure may present new strategies for the treatment of extensive defects of the trachea.
