In the present study, we investigated and compared the cardiopulmonary and oxidative stress effects of dogs undergoing open and thoracoscopic lung lobectomy. Ten healthy dogs, 5-8 years old, weighing 9-12 kg were used. The animals were randomly assigned to one of two groups according to the type of surgical procedure; open (group 1, n=5) or thoracoscopic lung lobectomy (group 2, n=5). Cardiopulmonary parameters, superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) concentrations were measured. There were statistically significant changes in arterial blood gases values in both groups. Total anesthesia and surgical times were significantly shorter in thoracoscopic lobectomy group compared with open surgery group. Increases in plasma SOD and CAT levels, and decreases in GPx levels were observed in both groups after surgery. Significant difference in GPx levels was found when the groups were compared. The GPx level was significantly lower in the thoracoscopic lobectomy group compared with the open surgery group.

Purpose of this study is to determine the reasonable portal approach for thoracoscopic right middle lung lobectomy in small sized dogs under 10 kg. Ten healthy beagle dogs weighing $8.67{\pm}0.49kg$ were included. Under general anesthesia, one-lung ventilation (1LV) was achieved using endobronchial blocker with guidance of fiber-optic bronchoscope. Two portal approaches were used; 8-6-10 intercostal space (ICS) and 8-6-5 ICS approach. Thoracoscopic right middle lung lobectomy was performed using endoscopic linear self-cutting stapler and specimen retrieval bag. Each approach was evaluated by scoring 0; bad, 1; endurable, 2; good, 3; excellent in following five category, 1) visualization, 2) triangulation; instrumental sword fighting in the thoracic cavity, 3) approach to hilar pedicle; application of stapler, 4) any obstacles in applicating Lap Bag, and 5) the operator's convenience. Favorable working space was secured by 1LV and thoracoscopic right middle lung lobectomy was successfully completed in all dogs. There was no need to change the portal location and iatrogenic complication. Most of scores were good to excellent in both approaches. Consequently, both approaches are feasible methods for thoracoscopic right middle lung lobectomy with one lung ventilation using endoscopic linear self-cutting stapler in dogs weighing less than 10 kg.

Video thoracoscopic surgery is a new modality that gains acceptance rapidly from thoracic surgeons. We have experienced two left lower lobectomies, one left upper lobectomy & one right upper lobectomy with using video thoracoscopy for the four patients with lung parenchymal disease from July 1992 to February 1993. The post-operative courses were uneventful. The final pathologic diagnosis were sclerosing hemangioma, adenocarcinoma, bronchiectasis, leiomyoma & the post-operative courses were short. These patients needed less analgesics because postoperative pain was reduced markedly, and hospitalization was shortened due to rapid recovery. We would like to prefer video thoracoscopic lobectomy to the lobectomy through standard thoracotomy in uncomplicated patients with simple pulmonary parenchymal diseases.

A 14-year-old, 3.9 kg, castrated male Maltese presented with an intermittent cough. A solitary mass ($1.6{\times}2{\times}1.8cm$) was located in right middle lung lobe on CT examination and thoracoscopic right middle lung lobectomy was performed without lung separation. The patient recovered uneventfully and was discharged at POD3. With a histopathologic diagnosis of pulmonary bronchoalveolar carcinoma, Re-evaluation via CT scanning with contrast on POD 50 and 255 revealed no evidence of residual, metastatic or recurrent lesions. The patient has been doing well since surgery during a 9-month follow-up period.

Objectives: To evaluate the safety, efficacy, and invasiveness of lobectomy by video-assisted thoracoscopic surgery (VATS) in the treatment of stage I/II non-small cell lung cancer (NSCLC). Methods: A total of 148 patients presenting with Stage I or II NSCLC were enrolled into our study, comprising 71 who underwent VATS and 77 patients undergoing conventional thoracotomic lobectomy, in combination with systematic lymph node resection. Results: It was found that VATS was superior to conventional thoracotomy in terms of the duration of surgery, intraoperative blood loss, frequency of the need to administer postoperative analgesia, thoracic intubation indwelling time, post-operative hospital stay, and survival rate (P<0.05). We saw no obvious difference in the number of resected lymph nodes with either approach. Conclusions: VATS lobectomy is a safe and reliable surgical approach for the treatment of Stage I/II NSCLC, characterized by significantly minimal invasiveness, rapid post-operative recovery, and markedly lower loss of blood.

Background: Video-assisted thoracoscopic surgery (VATS) lobectomy has become the major surgical option for the treatment of non-small cell lung cancer (NSCLC). Endoscopic instruments such as stapler cartridges are essential for VATS procedures. In this study, we investigated the factors that affect the number of stapler cartridges used in VATS lobectomy. Methods: A retrospective analysis was conducted of patients who underwent complete VATS lobectomy for NSCLC from January 2013 to December 2015. Results: In total, 596 patients underwent complete VATS lobectomy. The average number of stapler cartridges used for VATS lobectomy was 5.3±1.9. The number of stapler cartridges used for VATS lobectomy was higher in men (5.5±1.9 vs. 5.0±18, p=0.006), those aged older than 70 years (5.5±2.1 vs. 5.1±1.7, p=0.038), those who underwent upper or middle lobectomy procedures (5.7±1.9 vs. 4.1±1.2, p<0.001), those with a higher fissure sum average (p<0.001), and those in whom surgery was performed by a surgeon with a preference for staplers (5.6±2.0 vs. 4.9±1.6, p<0.001). Conclusion: The number of stapler cartridges required to perform VATS lobectomy in NSCLC patients appears to be influenced by sex, age, the location of the tumor, the degree of fissure development, and the surgeon's preference.

Serratus anterior plane block (SAPB) has been used for perioperative pain control during video-assisted thoracoscopic surgery (VATS), and the effects of continuous SAPB have been studied. This procedure is usually performed by the anesthesiologist; however, it could be performed more simply and safely by the thoracic surgeon through the use of meticulous finger dissection to create a space in the deep serratus anterior plane during surgery. We describe 3 cases of surgical catheterization for continuous SAPB in patients with lung cancer during VATS lobectomy, in which postoperative pain was effectively reduced.

Objective: To explore the feasibility of pulmonary lobectomy combined with pulmonary arterioplasty by complete video-assisted thoracic surgery (VATS) in patients with lung cancer, and summarize its surgical methods. Materials and Methods: Twenty-one patients with lung cancer in Beijing Chest Hospital Affiliated to Capital Medical University from Feb., 2010 to Jun., 2013 were selected, males and females accounting for 15 and 6 cases, respectively. Ten underwent right upper lobectomy, 5 right lower lobectomy, 4 left upper lobectomy (in which left upper sleeve lobectomy was conducted for 2) and 2 left lower lobectomy. At the same time, local resection of pulmonary arterioplasty was performed for 12 patients, and sleeve resection of pulmonary arterioplasty for 9. Results: Twenty-one patients recovered well after surgery. Thoracic drainage tube was maintained for 3-8 days, with an average of 4.9 days, and hospital stays were 8-15 days, with an average of 11 days. There were no deaths in the perioperative period, and the complications like pulmonary embolism, bronchopleural fistula, chest infection and pulmonary atelectasis did not occur after surgery. Conclusions: Performance of pulmonary lobectomy and pulmonary arterioplasty together by complete VATS is a safe and effective surgical method, which can expand the indications of patients with lung cancer undergoing thoracoscopic pulmonary lobectomy, and make more patients profit from such minimally invasive treatment.

Intraoperative events can occur during video-assisted thoracoscopic surgery (VATS) lobectomy due to unfavorable surgical anatomy, such as dense adhesions or calcifications around the pulmonary arteries. Troubleshooting intraoperative complications is essential for performing safe and successful VATS pulmonary resection and lymph node dissection. If continuous bleeding occurs or VATS does not proceed despite all measures, conversion to open thoracotomy should not be delayed.

Video-assisted thoracoscopic surgery (VATS) has been established as the surgical approach of choice for lobectomy in patients with early-stage non-small cell lung cancer (NSCLC). Patients with clinical stage I NSCLC with no lymph node metastasis are considered candidates for VATS lobectomy. To rule out the presence of metastasis to lymph nodes or distant organs, patients should undergo meticulous clinical staging. Assessing patients' functional status is required to ensure that there are no medical contraindications, such as impaired pulmonary function or cardiac comorbidities. Although various combinations of the number, size, and location of ports are available, finding the best method of port placement for each surgeon is fundamental to maximize the efficiency of the surgical procedure. When conducting VATS lobectomy, it is always necessary to comply with the following oncological principles: (1) the vessels and bronchus of the target lobe should be individually divided, (2) systematic lymph node dissection is mandatory, and (3) touching the lymph node itself and rupturing the capsule of the lymph node should be minimized. Most surgeons conduct the procedure in the following sequence: (1) dissection along the hilar structure, (2) fissure division, (3) perivascular and peribronchial dissection, (4) individual division of the vessels and bronchus, (5) specimen retrieval, and (6) mediastinal lymph node dissection. Surgeons should obtain experience in enhancing the exposure of the dissection target and facilitating dissection. This review article provides the basic principles of the surgical techniques and practical maneuvers for performing VATS lobectomy easily, safely, and efficiently.
