Use Of Video-assisted Thoracic Surgery Research Articles

The efficacy of thoracoscopic surgery for descending necrotizing mediastinitis.

Thoracotomy is a reliable approach for descending necrotizing mediastinitis (DNM), and the use of video-assisted thoracic surgery (VATS), a minimally invasive procedure, has been increasing. However, which approach is more effective for DNM treatment is controversial. We analysed patients who underwent mediastinal drainage via VATS or thoracotomy, using a database with DNM from 2012 to 2016 in Japan, which was constructed by the Japanese Association for Chest Surgery and the Japan Broncho-esophagological Society. The primary outcome was 90-day mortality, and the adjusted risk difference between the VATS and thoracotomy groups using a regression model, which incorporated the propensity score, was estimated. VATS was performed on 83 patients and thoracotomy on 58 patients. Patients with a poor performance status commonly underwent VATS. Meanwhile, patients with infection extending to both the anterior and posterior lower mediastinum frequently underwent thoracotomy. Although the postoperative 90-day mortality was different between the VATS and thoracotomy groups (4.8% vs 8.6%), the adjusted risk difference was almost the same, -0.0077 with 95% confidence interval of -0.0959 to 0.0805 (P = 0.8649). Moreover, we could not find any clinical and statistical differences between the 2 groups in terms of postoperative 30-day and 1-year mortality. Although patients who underwent VATS had higher postoperative complication (53.0% vs 24.1%) and reoperation (37.9% vs 15.5%) rates than those who underwent thoracotomy, the complications were not serious and most could be treated with reoperation and intensive care. The outcome of DNM treatment does not depend on thoracotomy or VATS.

Current role of Uniportal Video Assisted Thoracic Surgery for lung cancer treatment

Comparison between thoracoscopic and open approaches in thymoma resection.

To investigate the feasibility and indications of video-assisted thoracic surgery (VATS) in thymoma resection. The clinical data of 103 patients undergoing thymoma resection via different approaches [including conventional lateral thoracotomy approach (LTA) in 41 cases, median sternotomy approach (MSA) in 40 cases, and right-sided VATS in 22 cases] were analyzed. Among them, 59, 13, 25, and 6 patients were in Masaoka stage I, II, III, and IV, respectively. Myasthenia gravis (MG) was also found in 54 cases. The patients were followed up for postoperative survival and the improvement in MG. The prognostic indicators of patients undergoing thymoma resection via different surgical approaches (i.e., LTA, MSA, and VATS) were statistically analyzed. Eight of 103 patients died. Six patients underwent unilateral sacral nerve resection, among whom 4 patients developed respiratory dysfunction, and 3 died. Two patients died of MG after surgery, 1 patient died of tumor recurrence and metastasis, 1 patient died of heart disease, and the cause of death was unknown in the remaining patient. The drainage time was shorter in VATS group than in open groups, along with smaller tumor size. The VATS group also had shorter hospital stay in the whole series and the subgroup without accompanying MG. The improvement in MG showed no significant difference among the three surgical groups. Both 5- and 10-year survival rates were 91% in the entire cohort. VATS is like a conventional surgeries for improving MG in thymoma patients with accompanying MG. VATS resection can still be considered for thymoma that only invades the mediastinal pleura. For thymomas that have intact capsules and have not invaded mediastinal pleura, MSA surgery shall be performed to ensure patient safety if the anteroposterior diameters of the tumors are large and the masses have produced severe compression of the innominate vein, even if the tumors are still in the Masaoka stage II. For thymomas with large left-to-right diameters and with most parts of the tumors located in the left thoracic cavity, a left-sided approach (either VATS or an open approach) may be used in the absence of MG; if MG accompanies the condition, an MT approach or a bilateral VATS may be considered. In patients with unilateral pericardial phrenic nerve and/or local pericardial involvement, right-sided VATS thymectomy may be considered for thymomas located at the right side and bilateral VATS surgery can be performed for tumors located at the left side. In summary, VATS is feasible for the treatment of thymoma complicated by MG. VATS can be performed in patients with Masaoka stage I, II and (a certain portion of) III thymoma; for some patients with Masaoka stage II thymoma, especially those with compression of the innominate vein, the use of VATS should be cautious.

VATS anatomical resection (lobectomy or segmentectomy) for pulmonary metastasis

Metastasectomy is steadily gaining place in the arsenal of treatments of patients suffering from lung metastasis of colorectal carcinoma (CRC). Meanwhile thoracotomy has been the gold standard approach during years for lung metastasectomy of CRC, the use of video-assisted thoracic surgery (VATS) in this field is currently thriving. Indeed, in addition of known advantages of minimally-invasive surgery, VATS has shown equivalent oncologic outcomes in comparison to open techniques. Otherwise, several questions in the management of these particular patients remained unsolved. In particular, only few studies have explored the role of anatomical resections (i.e., segmentectomy/lobectomy/pneumonectomy) compared to wedge resections. Despite their low level of evidence, these studies highlight interesting preliminary results, in particular a survival advantage of anatomical resections over non-anatomical. Most recent works have even suggested a potential role of molecular markers to select candidates who would benefit from an anatomical resection.

Minimally invasive thoracic surgery for empyema.

The widely accepted and still increasing use of video-assisted thoracic surgery (VATS) in pleuro-pulmonary pathology imposes the need to deal with two major pitfalls: the first is to avoid its unselective use, while the second relates to inappropriate rejection of VATS on the basis of “insufficient radicality”. Unlike a quite established role of VATS in lung cancer patients, in patients with pleural empyema, the role of VATS is less clearly defined. The current evidence about VATS in patients with pleural empyema could be summarised as follows: VATS is accepted as a useful treatment option for fibrinopurulent empyema, but the treatment failure rate increases with the increasing proportion of stage III empyema, necessitating further surgical options like thoracotomy and decortication. As both pulmonologists and surgeons deal with diagnosis and treatment of pleural empyema, this article is an attempt to highlight the existing evidence in a more user-friendly way in order to help practising physicians to optimise the use of VATS in these patients. In other words, in the absence of randomised studies comparing VATS and thoracotomy, the key question to be answered is: are there any pre-operative findings that can be used to select patients for initial VATS versus proceeding directly to a thoracotomy?

Video-assisted thoracic surgery is an optimal alternative to conventional thoracotomy for reoperations for ipsilateral pulmonary lesions.

BackgroundIpsilateral pulmonary reoperation is empirically considered a contraindication of video‐assisted thoracic surgery (VATS) because of intrapleural adhesion and the destruction of anatomical structures caused by previous surgery. The purpose of this study was to present our experience of the use of VATS for ipsilateral reoperations.MethodsThe medical records of patients who underwent VATS reoperation or re‐thoracotomy between January 2006 and March 2017 were retrospectively reviewed. Data were compared to assess the feasibility and safety of VATS for ipsilateral reoperations.ResultsThe study enrolled 64 patients, including 36 patients who underwent attempted ipsilateral VATS reoperations (VATS group) and 28 who underwent conventional re‐thoracotomy as a control with clinicopathological characteristics similar to those in the VATS group. Intrapleural severe adhesions were detected in 28 (77.8%) and 22 (78.6%) patients in the VATS and re‐thoracotomy groups, respectively (P = 0.906), and their dissection required a longer period in the VATS group (P = 0.014). VATS reoperations were converted to re‐thoracotomy or video‐assisted mini re‐thoracotomy in three patients because of bleeding or difficulty in dissecting hilar structures. There were no significant differences in resection methods, time to reoperation, intraoperative blood loss, or drainage time between the two groups. However, patients in the VATS group had a shorter hospital stay (P < 0.01) and fewer complications (P = 0.042).ConclusionVATS is an optimal alternative to re‐thoracotomy for ipsilateral pulmonary lesions, regardless of intrapleural adhesions and the destruction of anatomical structures caused by former operations in selected patients.

Video-assisted thoracic surgery lobectomy beyond the learning curve

In the last decade an increasing, more and more widespread use of video-assisted thoracic surgery (VATS) anatomical lung resections has become a standard primary operative procedure in many thoracic units worldwide, especially in high volume centers.

Video-assisted thoracic surgery for thymoma: long-term follow-up results and prognostic factors-single-center experience of 150 cases.

The use of video-assisted thoracic surgery (VATS) in the treatment of thymoma is becoming more and more common. The aim of this study was to evaluate safety and effectiveness of thoracoscopic treatment of thymoma and, more importantly, to report long-term follow-up results of a large single-center cohort. A retrospective review of a prospective database was performed. In total, 150 patients who underwent VATS resection for thymoma at Peking University People's Hospital from April 2001 to November 2014 were retrospectively reviewed. Average operation time was 140.1±54.2 min, median blood loss was 50 mL (range, 10-700 mL), median post-operative drainage time was 3 days (range, 1-11 days), and median length of post-op stay was 5 days (range, 2-20 days); 134 patients (89.3%) were followed up successfully. Median follow-up was 59.5 months (range, 2-187 months). Five- and 10-year recurrence free survival (RFS) rates of entire group were 96.5% and 94.4%, respectively; 5- and 10-year RFS rates for Masaoka stages I + II were 98.1% and 98.1%, respectively; 5- and 6-year RFS rates for Masaoka stage III were 90% and 60%, respectively. One case of recurrence in five Masaoka stage IV patients was observed, and 4-year RFS was 80%. Multivariable analysis indicated that recurrence tended to occur in Masaoka stages III + IV patients (P=0.037, HR =12.69, 95% CI: 1.17-138.22) and older patients had a lower risk of recurrence (P=0.029, HR =0.87, 95% CI: 0.77-0.99). Myasthenia gravis (MG) presented in 44 patients (29.3%), of which 36 patients (81.8%) were followed up. Nine patients achieved complete remission, and 19 patients had symptom improvement after surgery. Overall response rate of MG was 77.8% (28/36). VATS was a safe and effective procedure for treatment of thymomas with satisfactory prognosis. MG with thymoma treated by VATS had comparable neurological outcome to that associated with the trans-sternal approach.

Robotic assisted lobectomy for locally advanced lung cancer.

Some series report the use of video-assisted thoracic surgery (VATS) in patients with locally advanced non-small cell lung cancer (NSCLC) but, few studies describe the use of the robotic approach specifically for locally advanced disease. One potential advantage of the robotic approach over traditional VATS is the increased radicality. While the benefit of the robotic approach over open thoracotomy is directly related to reduced surgical trauma and the improved tolerability in fragile patients that have received induction treatment. In case of occult N2 disease, robotic assisted surgery can translate into a quicker recovery with improved compliance with adjuvant treatments following surgery. Technical details are reported and described. The robotic instrument technology allows sharp and controlled dissection compared to the typical blunt sweeping methods used in most VATS lobectomy techniques. The authors believe that robotic technology favors a more radical resection in the case of complex locally advanced tumors. Robotic technology has some limitations that have affected adoption such as significant capital and maintenance costs, reduced operating room efficiencies, and a steep learning curve.

Minimally invasive lobectomy for early stage non-small cell lung cancer—it can be done without sacrificing oncologic outcomes

The introduction of minimally invasive surgical techniques to perform lobectomy for non-small cell lung cancer (NSCLC) has significantly changed the practice of general thoracic surgery over the past two decades. Since the first reports of the use of video-assisted thoracic surgery (VATS) to perform lobectomy for NSCLC in the early 1990s (1), many more studies across a wide array of cohorts have reported on short-term and long-term outcomes. Initial studies focused on the feasibility and reproducibility of the procedure (2), and then subsequent studies demonstrated VATS lobectomy had less morbidity compared to thoracotomy (3). Over time, studies have shown that a minimally invasive approach may be particularly beneficial in those patients with higher peri-operative risk due to advanced age or poor pulmonary function (4,5). More recently, experience with robotic-assisted lobectomy has been increasingly reported and a robotic approach appears to provide similar advantages over thoracotomy as a VATS approach (6). Despite these demonstrated benefits, universal adoption of minimally invasive lobectomy for early-stage NSCLC has not occurred (4,7,8).

A case with unusual localized thymoma was resected completely by uniportal video assisted thoracic surgery

Thymoma is a rare tumor usually localized anterior mediastinum. We herein reported a case with thymoma localized paracardiac area that was resected completely by uniportal video assisted thoracic surgery (VATS). In thorax tomography of the patient referring chest pain, limited well lesion was localized at right paracardiac region which pushed the lung parenchyma. The size of lesion that was in the anterior mediastinum adjacent to the right atrium was approximately 50x33 mm and its average density was 52 HU. We performed VATS. The lesion was removed en bloc using by single port disection. The radiological differential diagnosis of the lesion was considered bronchogenic cysts and pericardial cysts, and was reported as type AB thymoma by pathologists. Thymomas are commonly observed anterior mediastinum. The diagnosis of atypical localization of thymomas is usually difficult. Hence increasing use of VATS provides minimally invasive diagnosis and treatment of mediastinal mass. Pam Med J 2016;9(2):167-169

Video-assisted thoracic surgery in a Nigerian teaching hospital: Experience and challenges.

Video-assisted thoracic surgery (VATS) is well established. Its application in Nigeria has however been limited and not been reported. The aim of this study was to describe our institutional experience and challenges with VATS. This was a retrospective cross-sectional study of all patients that underwent VATS in our institution between March 2008 and June 2013. Data were extracted from a prospectively maintained database. Two hundred and sixty-one patients were assessed as potential VATS cases. VATS was initiated in 26 patients, but completed in 25 patients (9.6%) as there was one case of conversion of a planned VATS bullectomy due to the failure of one lung ventilation. There were 12 males and 13 females. Mean age was 40.7 ± 13.9 years. The indication was interstitial lung disease in 9 patients (36%), malignant pleural effusion in 6 patients (24%), spontaneous pneumothorax in 5 patients (20%), indeterminate pulmonary nodule in 2 patients (8%), pleural endometriosis in 2 patients (8%) and bronchogenic cyst in one patient (4%). Procedures performed were lung biopsy in 13 patients (52%), pleural biopsy and pleurodesis in 6 patients (24%), bullectomy and pleurodesis in 5 patients (20%) and excision of bronchogenic cyst in one patient (4%). Mean hospital stay was 4 ± 0.7 days. There were no complications and no mortalities. VATS is being performed in our institution with successful outcomes. The use of VATS in Nigeria is encouraged. The relatively high cost of VATS is, however, a major limitation to more widespread use.

Initial management of primary spontaneous pneumothorax with video-assisted thoracoscopic surgery: a 10-year experience.

First-line conservative treatment of primary spontaneous pneumothorax (PSP) may be challenged by recurrence rates and complications associated with different treatment options. The aim of this study was to evaluate the use of a standardized surgical treatment as 'first-line' treatment. In a 10-year period, 185 patients with PSP were treated with a standardized video-assisted thoracic surgery (VATS) approach including wedge resection and parietal pleurectomy. Data were evaluated retrospectively. All patients with a first event of PSP were included in the study. In addition, follow-up was done by a questionnaire. Mean follow-up period was 70.8 months (±33.5 months). Sub-pleural emphysematous changes were found in every histopathological specimen. In addition, 70.8% had fibrosis of visceral pleura. Recurrence occurred in 4 patients (2.2%). Ten-year freedom from recurrence was 96.2%. Procedure-related morbidity rate was 7.6%. Approximately 85.7% of patients were satisfied with the procedure and the cosmetic result. Three patients died during follow-up (1.6%). Treatment of first episode of PSP by VATS is a safe procedure, with a very low rate of recurrence and a high patient satisfaction. This management of first episode of PSP is based on the underlying pathology. We recommend the use of VATS as the treatment of first choice for patients with PSP.

Spontaneous hemopneumothorax: Our experience with surgical management

Spontaneous hemopneumothorax is rare, accounting for only 1%-12% of patients presenting with spontaneous pneumothorax. The optimal management of these patients remains controversial with no definitive guidelines on patient selection and timing of surgery. The aim of this study was to review our institution's surgical experience in the management of patients with spontaneous hemopneumothorax. We performed a retrospective review of all patients with spontaneous hemopneumothorax who underwent surgery from January 2000 to June 2013. Patient data were obtained from our institution's primary spontaneous pneumothorax database. Of 510 patients who underwent surgery for spontaneous pneumothorax, 33 (6.4%) developed spontaneous hemopneumothorax. The mean age was 24.0 years (range 16-40 years). In 30 (90.9%) patients, it was their first presentation of pneumothorax. There were 25 (75.8%) patients with Vanderschueren stage III spontaneous pneumothorax. Blood loss ranged from 250 to 3000 mL (mean 1280 mL). In 28 patients, a torn adhesion band was the source of bleeding. Thoracotomy was the surgical approach in 9 (27.3%) patients, and video-assisted thoracic surgery was used in 24 (72.7%). One patient required reoperation for retained clots. There was no mortality. Our results suggest that surgical management of spontaneous hemopneumothorax can be undertaken with minimal morbidity and mortality. With the increasing use of video-assisted thoracic surgery, definitive surgical management of spontaneous hemopneumothorax can be instituted earlier.

Needlescopic video-assisted wedge resection combined with the subcostal trans-diaphragmatic approach for undetermined peripheral pulmonary nodules

Reduced mortality from lung cancer by computed tomography (CT) screening facilitates the use of video-assisted thoracic surgery (VATS) lung wedge resection to obtain a definite diagnosis and to treat tiny nodules. The authors evaluated their initial experience using novel needlescopic VATS wedge resection combined with the subcostal trans-diaphragmatic (SCTD) approach for managing undetermined peripheral pulmonary nodules. Between 2009 and 2012, 35 patients who had 36 operations underwent needlescopic VATS wedge pulmonary resection with the SCTD approach. Preoperative percutaneous CT-guided marking of the nodule was performed. Two 3-mm miniports were placed in the thorax for the thoracoscopic camera and minigrasper. Just anterior to the 10th rib, a 2-cm subcostal incision was made, and a 12- or 15-mm port was placed trans-diaphragmatically into the chest cavity. Wedge resection of the lung was performed with endostaplers introduced through a subcostal port. The median tumor size was 1.1cm. Localization of the tumor was widely distributed. The mean operation time was 51min, and the mean blood loss was 4.2mL. No patients required conversion to thoracotomy, and one patient required conversion to conventional VATS. Additional thoracic ports were placed in five patients, and the needlescopic incision was extended to 15mm in one patient. The median duration of chest drainage was 1day. Additional analgesia was not required for 22 patients and was used for less than 1day for three patients, less than 2days for seven patients, and less than 3days for seven patients. The pathologic diagnosis of the nodules was malignant for 28 patients and benign for 8 patients. On postoperative day 7 or at admission, 34 patients were free of postoperative neuralgia. Needlescopic VATS wedge pulmonary resection combined with the SCTD approach is both safe and feasible and offers the specific advantages of minimal invasiveness and good cosmetic outcomes.

Video-assisted thoracoscopic management for emphysema associated with contralateral destroyed lung.

Surgery can be quite challenging in condition that contralateral lung has no function. We report 3 cases of emphysema associated with contralateral destroyed lung managed with the use of video-assisted thoracic surgery (VATS). From December 2007 to December 2008, 3 patients of emphysema associated with contralateral destroyed lung were operated on by VATS. There were two pulmonary wedge resections and mechanical pleurodesises for pneumothorax and one lung volume reduction surgery (LVRS) for worsening dyspnea. Their records were reviewed retrospectively. No postoperative mortality was observed. One case for pneumothorax experienced prolonged postoperative air leakage. Of all the three cases, two cases for pneumothorax had no recurrence and one case for worsening dyspnea had improved lung function. VATS for emphysema associated with contralateral destroyed lung is feasible in selected patients.

Video-assisted thoracic surgery repair of subclavian artery injury following central venous catheterization: a new approach

Iatrogenic subclavian artery puncture following central venous catheterization is a rare but potentially fatal complication. There are very few reports in the literature on this condition. We propose the use of video-assisted thoracic surgery (VATS) in the management of these injuries. The technique of VATS to manage subclavian artery injury was described. We presented the first reported case of successful repair of subclavian artery injury using VATS. Using a two-incisional approach for VATS, the haemothorax was rapidly evacuated and the subclavian artery injury was successfully repaired using pledgetted sutures under direct thoracoscopic visualization. The patient had an uneventful postoperative recovery. VATS can be successfully applied to repair subclavian artery injury. The advantages include rapid intrathoracic access, excellent thoracoscopic visualization of the thoracic inlet, and avoidance of the morbidity associated with open thoracotomy.

Thoracoscopic Pneumonectomy for Non-Small Cell Lung Cancer (NSCLC): A Case Report and Review of the Literature

Minimally invasive resection of lung cancer remains surprisingly uncommon in comparison to the adoption of similar techniques in other surgical disciplines. The reported use of video-assisted thoracic surgery (VATS) lobectomy for anatomic resections in comparison to open lobectomy ranges from 10% -40% even though it has been demonstrated to be equivalent in safety and accomplishes the same oncologic goals. Further, it may provide improved survival outcomes as others have reported benefits in perioperative recovery and patient satisfaction. VATS pneumonectomy has been far less commonly described despite the physiologic advantages such as less blood loss, shorter intensive care stay, and less respiratory compromise. This report specifically addresses this lacuna by drawing upon the successful case of a VATS pneumonectomy with fissure invasion and then considering why minimally invasive VATS techniques remain underutilized. In conclusion, we suggest that focused thoracic surgery fellowship training in VATS techniques will make thoracoscopic surgery a more conventional technique rather than a challenging procedure.

Lung Cancer Screening and Video-Assisted Thoracic Surgery

The objective of this study is to report the impact of computed tomography (CT) screening on the use of Video-Assisted Thoracic Surgery (VATS) in a randomized screening trial. The Danish Lung Cancer Screening Trial is a randomized clinically controlled trial of 4104 smokers and previous smokers who were randomized to either screening with five annual low-dose CT scans or no screening in Copenhagen from 2004 to 2006. The major end point is the effect of CT screening on lung cancer mortality and treatment options. All diagnostic and treatment interventions in both groups were monitored prospectively until 1 to 3 years after the last screening round. By February 1, 2011 68 cases of lung cancer were detected in the screening group. Furthermore, seven patients with a benign nodule underwent surgical treatment because of suspicion of malignancy (12%). Fifty-one of the 68 lung cancer patients were eligible for surgical treatment. Eight patients had open thoracotomy. Of the operations for lung cancer, 84% were performed by VATS in the CT-screened arm, significantly higher than the control arm (p < 0.05). Thirty-six patients had a VATS lobectomy. One patient had a VATS segmentectomy, and four patients had a VATS wedge resection. The seven benign nodules were all treated with VATS. CT screening seems to facilitate the use of VATS in the treatment of lung cancer with an 84% rate in our data. Furthermore, all benign nodules could be removed by VATS. In our view, a basic requirement for a surgical institution to be involved in lung cancer CT screening is a dedicated VATS program.
