Background: Non-intubated, or awake, video-assisted thoracoscopic surgery has been implemented for non-anatomical lung resection and the results obtained were encouraging to consider the approach for anatomical pulmonary resection. This study was conducted to evaluate the perioperative outcomes of the non-intubated and intubated video-assisted thoracoscopic lobectomy in lung cancer in regards to feasibility and safety. Methods: A retrospective analysis of 62 consecutive video-assisted thoracoscopic lobectomies (31 lobectomies as non-intubated, 31 lobectomies as intubated) performed in Seoul St. Mary’s Hospital, The Catholic University of Korea between January and December 2016. Results: Both groups share comparable clinical characteristics including the age, sex, BMI, FEV1, DLCO, smoking history, lung lobes procedure, histological type and pathological staging. There was no difference in the mean of postoperative hospitalization period (6.9 versus 7.6 days, P=0.578) and the total chest tube duration (5.6 versus 5.4 days, P=0.943) between non-intubated and intubated lobectomy respectively. Both groups had a comparable surgical outcome for the anesthesia duration, operative time, blood loss and postoperative complications. The operative time required for lobe-specific surgery was shorter in the non-intubated group except for the LLL (mean 121.7 minutes for non-intubated group versus 118.3 minutes for the intubated group). The only statistically significant surgical outcome was for the number of dissected lymph nodes between both groups (the mean number of nodes for the non-intubated group was 12.6 versus 18.0 nodes for the intubated group, P=0.003). One patient in the non-intubated group required conversion to single lung intubation and mini-thoracotomy because of bleeding with no conversion in the intubated group. No mortality encountered in either group. Conclusions: The perioperative surgical outcomes for the non-intubated video-assisted thoracoscopic lobectomy are comparable to the intubated technique. Non-intubated video-assisted thoracoscopic lobectomy is safe and is technically feasible. However, further prospective randomized studies are needed for a better comparison between non-intubated and intubated VATS lobectomy.

Aim. To study the efficacy of E-VAC therapy for patients with anastomotic leakage after esophagectomy. Methods. Between January 2013 and April 2017, 12 patients underwent E-VAC therapy for the management of postoperative leakage. Their clinical features and endoscopic procedure details, therapy results, adverse events, and survival were investigated. Results. All 12 patients were male and the median age was 57 years (interquartile range 51.5–62.8 years). The reasons for esophageal surgery were esophageal cancer (83.3%), gastrointestinal stromal tumor (8.3%), and esophageal diverticulum (8.3%). Prior to E-VAC therapy, 6 patients had undergone failed primary surgical repair and the median duration from esophagectomy to leakage discovery was 13.5 days (IQR 6–207 days). The median duration of E-VAC therapy was 25 days (IQR 13.5–34.8 days) and the average sponge exchange rate was 2.7 times during the treatment period. After E-VAC therapy, 8 patients (66.7%) had complete leakage closure, 3 (25%) had a decreased leakage size, and 1 (8.3%) was unchanged. The three patients with a decreased leakage size after E-VAC therapy were treated with endoscopic and conservative management without further surgery. Conclusion. With proper patient selection, E-VAC therapy is a feasible and safe method for the treatment of anastomotic leakage after esophagectomy.

Background: Non-intubated thoracoscopic surgery is an evolving form of minimally-invasive thoracic surgery. We commenced performing non-intubated thoracoscopic surgery at our center in August 2016. We would like to report our initial experience, over a period of 1 year, with this procedure. Methods: From August 2016 to August 2017, non-intubated thoracoscopic surgery was performed in a series of consecutive patients who underwent thoracoscopic surgery in those who did not meet any of the following exclusion criteria: body mass index (BMI) >30, expected difficult airway, expected extensive pleural adhesion, severe cardiopulmonary dysfunction, persistent cough or excessive airway secretion, high risk of gastric reflux, and underlying neurological disorder. Results: A total of 115 consecutive patients underwent non-intubated thoracoscopic surgery. Of these, 83 (72.2%) of patients had lung cancers that had undergone pulmonary resection and the other 32 (27.8%) patients were diagnosed with pulmonary metastasis, benign lung diseases, thymic tumor or other conditions. The mean time of anesthesia was 172.4 min and time of operation was 130 min. The mean postoperative chest tube duration was 3.9 days and time of hospital stay was 6.0 days. There were 9 conversions (7.8%) to intubation, due to increased respiratory movement with intraoperative hypoxemia or severe pleural adhesion. There were 16 complications (13.9%) following surgery, but all of these were successfully managed during the period of hospital stay. There was no postoperative mortality. In multivariate analysis, old age and high BMI were significant risk factors for conversion to intubation (hazard ratio =1.122, P=0.038; hazard ratio =1.408, P=0.042, respectively). Conclusions: Non-intubated thoracoscopic surgery can safely be performed in selected patients.

We report our surgical technique for nonintubated uniportal video-assisted thoracoscopic surgery (VATS) pulmonary resection and early postoperative outcomes at a single center. Between January and July 2017, 40 consecutive patients underwent nonintubated uniportal VATS pulmonary resection. Multilevel intercostal nerve block was performed using local anesthesia in all patients, and an intrathoracic vagal blockade was performed in 35 patients (87.5%). Twenty-nine procedures (72.5%) were performed in patients with lung cancer (21 lobectomies, 6 segmentectomies, and 2 wedge resections), and 11 (27.5%) in patients with pulmonary metastases, benign lung disease, or pleural disease. The mean anesthesia time was 166.8 minutes, and the mean operative duration was 125.9 minutes. The mean postoperative chest tube duration was 3.2 days, and the mean hospital stay was 5.8 days. There were 3 conversions (7.5%) to intubation due to intraoperative hypoxemia and 1 conversion (2.5%) to multiportal VATS due to injury of the segmental artery. There were 7 complications (17.5%), including 3 cases of prolonged air leak, 2 cases of chylothorax, 1 case of pleural effusion, and 1 case of pneumonia. There was no in-hospital mortality. Nonintubated uniportal VATS appears to be a feasible and valid surgical option, depending on the surgeon's experience, for appropriately selected patients.

Intrapulmonary solitary fibrous tumors (SFTs) are sporadic mesenchymal neoplasms that typically arise from visceral or parietal pleura. While accounting for <5% of all pleural tumors, SFTs are known to occur in nearly all bodily organs, including nasopharynx, bladder, prostate, soft tissue of neck, buttocks, extremities, and abdominal wall. Such tumors have been previously designated localized fibrous mesothelioma or pleural fibroma. SFTs have no genetic basis and are unrelated to environmental factors such as tobacco smoking or asbestos exposure. Herein, we describe a 24-year-old woman whose clinical presentation mimicked atypical carcinoid tumor. A diagnosis of intrapulmonary SFT was achieved by surgical resection.
