Video assisted thoracic surgery for treatment of pneumothorax and lung resections: systematic review of randomised clinical trials

<b>Objectives</b> To determine if video assisted thoracic surgery is associated with better clinical outcomes than thoracotomy for three common procedures: surgery for pneumothorax, minor resections, and lobectomy. <b>Design</b> Systematic review of randomised clinical trials. <b>Data sources</b> Medline, Embase, Cochrane database of systematic reviews, Cochrane controlled trials register. Reference lists of relevant articles and reviews. <b>Methods</b> Criteria for inclusion were random allocation of patients and no concurrent use of another experimental medication or device. At least two authors performed and confirmed data abstraction and analyses. Information on quality of trials, demographics, frequency of the events, and numbers randomised were collected. <b>Results</b> 12 trials randomised 670 patients. Video assisted thoracic surgery was associated with shorter length of stay (reduction ranged from 1.0 to 4.2 days) and less pain or use of pain medication than thoracotomy in the five out of seven trials in which the technique was used for pneumothorax or minor lung resection. In the treatment of pneumothorax, video assisted thoracic surgery was associated with substantially fewer recurrences than pleural drainage in two trials (from 20 to 53 events prevented per 100 treated patients). No substantial advantages were observed for video assisted thoracic surgery in lobectomies. <b>Conclusions</b> Video assisted thoracic surgery is associated with better outcomes and seems to have a complication profile comparable with that of thoracotomy for the treatment of pneumothorax and minor resections. As for lobectomy, further studies are needed to determine how it compares with thoracotomy

Long term compensatory sweating results after sympathectomy for palmar and axillary hyperhidrosis

Endoscopic thoracic sympathectomy is currently the best treatment for primary upper extremity hyperhidrosis, but the potential for adverse effects, particularly the development of compensatory sweating, is a concern and often precludes surgery as a definitive therapy. This study aims to evaluate long-term results of two-stage unilateral versus one-stage bilateral thoracoscopic sympathectomy

Video-assisted thoracoscopic pericardial fenestration for loculated or recurrent effusions

Objective: The validity of video-assisted thoracoscopic pericardial fenestration was prospectively assessed for loculated effusions, effusions previously treated by percutaneous catheter manoeuvres and those with concurrent pleural diseases. Methods: Inclusion criteria consisted of echocardiographically documented pericardial effusions requiring diagnosis or relief of symptoms and recurrent effusions after failed percutaneous drainage and balloon pericardiotomy. Pre-operative CT-scan was used to delineate additional pleural pathology and to determine the side of intervention. All patients were followed clinically and by echocardiographic examination 3 months post-operatively. Results: Twenty-four patients underwent thoracoscopic pericardial fenestration with 11 patients (54%) being previously treated by percutaneous catheter drainage, balloon pericardiotomy or subxyphoidal fenestration. Pre-operative echocardiography revealed septation and loculation in 18 patients (72%). Additional pleural pathology was identified on CT scan in 12 patients (50%) and talc pleurodesis was performed in six patients, all suffering from malignant pleural effusion. The mean operation time was 45 min (range 30-60 min) with no complications being observed. All patients were followed 3 months post-operatively by clinical and echocardiographic examination; relief of symptoms was achieved in all patients but echocardiography showed a recurrence in one patient (4%). Another recurrence was found by echocardiography after a mean follow-up time of 33 months in the 12 patients suffering from a non-malignant pericardial effusion. No recurrence of pleural or pericardial effusion was observed in the subset of patients with talc pleurodesis. Conclusion: Video-assisted thoracoscopic pericardial fenestration is safe and effective for loculated pericardial effusions previously treated by percutaneous drainage manoeuvres and those with concomitant pleural diseas

A standardized comparison of peri-operative complications after minimally invasive esophagectomy: Ivor Lewis versus McKeown.

BACKGROUND: While our institutional approach to esophageal resection for cancer has traditionally favored a minimally invasive (MI) 3-hole, McKeown esophagectomy (MIE 3-hole) during the last five years several factors has determined a shift in our practice with an increasing number of minimally invasive Ivor Lewis (MIE IL) resections being performed. We compared peri-operative outcomes of the two procedures, hypothesizing that MIE IL would be less morbid in the peri-operative setting compared to MIE 3-hole. METHODS: Our institution\u27s IRB-approved esophageal database was queried to identify all patients who underwent totally MI esophagectomy (MIE IL vs. MIE 3-hole) from June 2011 to May 2016. Patient demographics, preoperative and peri-operative data, as well as post-operative complications were compared between the two groups. Post-operative complications were analyzed using the Clavien-Dindo classification system. RESULTS: There were 110 patients who underwent totally MI esophagectomy (MIE IL n = 49 [45%], MIE 3-hole n = 61 [55%]). The majority of patients were men (n = 91, 83%) with a median age of 62.5 (range 31-83). Preoperative risk stratifiers such as ECOG score, ASA, and Charlson Comorbidity Index were not significantly different between groups. Anastomotic leak rate was 2.0% in the MIE IL group compared to 6.6% in the MIE 3-hole group (p = 0.379). The rate of serious (Clavien-Dindo 3, 4, or 5) post-operative complications was significantly less in the MIE IL group (34.7 vs. 59.0%, p = 0.013). Serious pulmonary complications were not significantly different (16.3 vs. 26.2%, p = 0.251) between the two groups. CONCLUSIONS: In this cohort, totally MIE IL showed significantly less severe peri-operative morbidity than MIE 3-hole, but similar rates of serious pulmonary complications and anastomotic leaks. These findings confirm the safety of minimally invasive Ivor Lewis esophagectomies for esophageal cancer when oncologically and clinically appropriate. Minimally invasive McKeown esophagectomy remains a satisfactory and appropriate option when clinically indicated

Video-assisted thoracoscpic muscle transposition for acute empyema.

Muscle flap transposition is one of the surgical treatment options for empyema with alveolarpleural fistula (APF) or bronchopleural fistula (BPF). This surgical procedure is invasive because it is typically performed by standard thoracotomy. We performed video-assisted thoracoscopic surgery (VATS) debridement, decortication, and obliteration of an empyema cavity using a pedicled latissimus dorsi muscle (LDM) flap harvested through minimal skin incisions for a case of acute empyema with APF. This VATS procedure is effective and less invasive and can be a new option for the thoracoscopic surgical treatment of acute empyema with APF

Hybrid endoscopic thymectomy : combined transesophageal and transthoracic approach in a survival porcine model with cadaver assessment

BACKGROUND: Video-assisted thoracoscopic surgery thymectomy has been used in the treatment of Myastenia Gravis and thymomas (coexisting or not). In natural orifice transluminal endoscopic surgery, new approaches to the thorax are emerging as alternatives to the classic transthoracic endoscopic surgery. The aim of this study was to assess the feasibility and reliability of hybrid endoscopic thymectomy (HET) using a combined transthoracic and transesophageal approach. METHODS: Twelve consecutive in vivo experiments were undertaken in the porcine model (4 acute and 8 survival). The same procedure was assessed in a human cadaver afterward. For HET, an 11-mm trocar was inserted in the 2nd intercostal space in the left anterior axillary line. A 0° 10-mm thoracoscope with a 5-mm working channel was introduced. Transesophageal access was created through a submucosal tunnel using a flexible gastroscope with a single working channel introduced through the mouth. Using both flexible (gastroscope) and rigid (thoracoscope) instruments, the mediastinum was opened; the thymus was dissected, and the vessels were ligated using electrocautery alone. RESULTS: Submucosal tunnel creation and esophagotomy were performed safely without incidents in all animals. Complete thymectomy was achieved in all experiments. All animals in the survival group lived for 14 days. Thoracoscopic and postmortem examination revealed pleural adhesions on site of the surgical procedure with no signs of infection. Histological analysis of the proximal third of the esophagus revealed complete cicatrization of both mucosal defect and myotomy site. In the human cadaver, we were able to replicate all the procedure even though we were not able to identify the thymus. CONCLUSIONS: Hybrid endoscopic thymectomy is feasible and reliable. HET could be regarded as a possible alternative to classic thoracoscopic approach for patients requiring thymectomy.This project was funded by the FCT Grants project PTDC/SAU-OSM/105578/2008

Video-thoracoscopic pericardial drainage in the treatment of pericardial effusions

OBJECTIVES: To assess efficacy and safety of videothoracoscopic pericardial drainage in the treatment and diagnostic of pericardial effusion through 26 cases review. METHODS: From April 2005 to December 2007, 26 patients with pericardial effusion underwent a video-thoracoscopic pericardial window. Median age was 48.2 years old. Dyspnea was the most frequent symptom followed by thoracic pain. The procedure was performed in lateral decubitus, under general anesthesia and selective intubation with the aid of three trocars. RESULTS: Procedure accomplish was feasible in 25 cases. One conversion occurred. In 61.53% of the cases the procedure was able to modify the initial diagnosis. Microbiology and tissue culture were negative in all cases. Neoplasia was present in nine cases, tuberculosis in two, aspergillosis in one, postoperative heart surgeries in three; lupus in two, uremia in one and idiopathy in eight. Associated pleuropulmonary procedures were performed in four cases. No deaths related to the procedure occurred. One late recurrence was recorded. CONCLUSION: The procedure is feasible, safe, reproducible and allowed an etiologic diagnostic. Specific treatment could be initiated in some cases. The intervention could possibly be the new gold standard treatment of pericardial effusion in selected patients.OBJETIVOS: Analisar a eficácia e a segurança da drenagem pericárdica videotoracoscópica no tratamento e diagnóstico etiológico dos derrames pericárdicos por meio da revisão de 26 casos. MÉTODOS: De abril de 2005 a dezembro de 2007, 26 pacientes com derrame pericárdico foram submetidos ao procedimento. A média etária foi de 48,2 anos. O sintoma mais comum foi dispnéia, seguida por dor torácica. O procedimento foi realizado em decúbito lateral, sob anestesia geral e intubação seletiva, com o auxílio de três trocateres. RESULTADOS: A realização do procedimento foi possível em 25 casos. Ocorreu uma conversão. Em 61,53% dos casos, o procedimento foi capaz de alterar o diagnóstico inicial. Culturas e microbiologia foram negativas em todos os casos. Achados compatíveis com neoplasia estavam presentes em nove casos, tuberculose em dois, aspergilose em um, pós-cirúrgico em três, lúpico em dois, urêmico em um e oito idiopáticos. Em quatro casos, procedimentos pleuropulmonares concomitantes foram realizados. Não ocorreram óbitos relacionados ao procedimento. Ocorreu uma recidiva. CONCLUSÃO: O procedimento demonstrou ser seguro, reprodutível e eficaz, capaz de fornecer diagnóstico etiológico e mudar o curso terapêutico de alguns pacientes. O procedimento pode se tornar o padrão-ouro em doentes selecionados.UNIFESP-EPMUNIFESP, EPMSciEL

Binocular stereo-navigation for three-dimensional thoracoscopic lung resection

BACKGROUND: This study investigated the efficacy of binocular stereo-navigation during three-dimensional (3-D) thoracoscopic sublobar resection (TSLR). METHODS: From July 2001, the authors’ department began to use a virtual 3-D pulmonary model on a personal computer (PC) for preoperative simulation before thoracoscopic lung resection and for intraoperative navigation during operation. From 120 of 1-mm thin-sliced high-resolution computed tomography (HRCT)-scan images of tumor and hilum, homemade software CTTRY allowed sugeons to mark pulmonary arteries, veins, bronchi, and tumor on the HRCT images manually. The location and thickness of pulmonary vessels and bronchi were rendered as diverse size cylinders. With the resulting numerical data, a 3-D image was reconstructed by Metasequoia shareware. Subsequently, the data of reconstructed 3-D images were converted to Autodesk data, which appeared on a stereoscopic-vision display. Surgeons wearing 3-D polarized glasses performed 3-D TSLR. RESULTS: The patients consisted of 5 men and 5 women, ranging in age from 65 to 84 years. The clinical diagnoses were a primary lung cancer in 6 cases and a solitary metastatic lung tumor in 4 cases. Eight single segmentectomies, one bi-segmentectomy, and one bi-subsegmentectomy were performed. Hilar lymphadenectomy with mediastinal lymph node sampling has been performed in 6 primary lung cancers, but four patients with metastatic lung tumors were performed without lymphadenectomy. The operation time and estimated blood loss ranged from 125 to 333 min and from 5 to 187 g, respectively. There were no intraoperative complications and no conversion to open thoracotomy and lobectomy. Postoperative courses of eight patients were uneventful, and another two patients had a prolonged lung air leak. The drainage duration and hospital stay ranged from 2 to 13 days and from 8 to 19 days, respectively. The tumor histology of primary lung cancer showed 5 adenocarcinoma and 1 squamous cell carcinoma. All primary lung cancers were at stage IA. The organs having metastatic pulmonary tumors were kidney, bladder, breast, and rectum. No patients had macroscopically positive surgical margins. CONCLUSIONS: Binocular stereo-navigation was able to identify the bronchovascular structures accurately and suitable to perform TSLR with a sufficient margin for small pulmonary tumors
