OBJECTIVES The relationship between operating time and postoperative morbidity has not been fully characterized in lung resection surgery. We aimed to determine the variables associated with prolonged operative times and their influence on postoperative complications after video-thoracoscopic lobectomy. METHODS Patients undergoing thoracoscopic lobectomy for lung cancer from December 2016 to March 2018, within the prospective registry of the Spanish Video-Assisted Thoracic Surgery Group were identified. Operating time was stratified by quartiles and complication rates analysed using chi-squared test. Primary outcomes included 30-day overall, pulmonary and cardiovascular complications and wound infection. Multivariable logistic regression analyses were performed to identify variables independently associated with operating time and their influence on the occurrence of postoperative complications. RESULTS Data of 1518 cases were examined. The median operating time was 174 min (interquartile range: 130–210 min). Overall morbidity rates significantly increased with surgical duration (20.5% vs 34.4% in the 1st and 4th quartiles, respectively, P CONCLUSIONS Prolonged operating time is associated with increased odds of postoperative complications. Modifiable factors contributing to prolonged operating time may serve as a target for quality improvement.

Introducción: El objetivo del estudio es valorar el rendimiento diagnóstico de la tomografía computarizada (TC) y la tomografía por emisión de positrones (PET) en la estadificación clínica mediastínica del cáncer pulmonar quirúrgico según los datos de la cohorte prospectiva del Grupo Español de Cirugía Torácica Videoasistida (GEVATS). Métodos: Se han analizado 2.782 pacientes intervenidos por carcinoma pulmonar primario. Se ha estudiado el acierto diagnóstico en la estadificación mediastínica (cN2). Se ha realizado un análisis bivariante y multivariante de los factores que influyen en el acierto. Se ha estudiado el riesgo de pN2 inesperado en los factores con los que se recomienda una prueba invasiva de estadificación: cN1, tumor central o tamaño mayor de 3cm. Resultados: El acierto global de la TC y PET en conjunto es del 82,9% con VPP y VPN de 0,21 y 0,93. En tumores mayores de 3cm y a mayor SUVmax del mediastino, el acierto es menor, OR de 0,59 (0,44 - 0,79) y 0,71 (0,66 - 0,75), respectivamente. En el abordaje VATS el acierto es mayor, OR de 2,04 (1,52 - 2,73). El riesgo de pN2 inesperado aumenta con el número de los factores cN1, tumor central o tamaño mayor de 3cm: entre el 4,5% (0 factores) y 18,8% (3 factores), pero no hay diferencias significativas con la realización de prueba invasiva. Conclusiones: La TC y PET en conjunto tienen un elevado valor predictivo negativo. Su acierto global es menor en tumores mayores de 3cm y SUVmax del mediastino elevado, y mayor en el abordaje VATS. El riesgo de pN2 inesperado es mayor si cN1, tumor central o mayor de 3cm y no varía significativamente con prueba invasiva.

OBJECTIVES The aim of this study was to know the treatment effect of video-assisted thoracic surgery (VATS) on 90-day mortality after anatomical lung resection based on a nationwide cohort. METHODS This is a multicentre prospective cohort of 2721 anatomical resections for lung cancer from December 2016 to March 2018. Treatment and intention-to-treat (ITT) analyses were performed after inverse probability score weighting and different propensity score matching algorithms. Covariate balance was assessed by standardized mean differences. The estimators reported were the average treatment effect, the average treatment effect on the treated and odds ratios after conditional logistic models with 95% confidence intervals. The unconfoundedness assumption was evaluated by sensitivity analysis for average treatment effect (c-dependence) and average treatment effect on the treated (Γ). RESULTS VATS was the initial approach in 1911 patients (70.2%), though 273 cases (14.3%) had to be converted to thoracotomy. Ninety-day mortality rates were: treatment analysis (VATS 1.16% vs open 3.9%, P < 0.001), ITT analysis (VATS 1.78% vs open 3.36%, P = 0.012). After inverse probability score weighting and propensity score matching, in the treatment analysis, VATS meant absolute risk reductions between 2.25% and 2.96% and relative risk reductions between 65% and 70% [OR = 0.34 (95% confidence interval 0.15–0.79), all P-values CONCLUSIONS VATS can reduce the risk of 90-day mortality after anatomical lung resection. However, the implications of conversion to thoracotomy, comparing ITT versus treatment analysis, and the potential impact of hidden bias should deserve further attention in the future.

Video-assisted thoracoscopic surgery (VATS) lung-sparing anatomical resections preserve healthy pulmonary parenchyma but also lead to good resection margins. Oncological outcomes are similar when compared with lobectomy for the treatment of early stage lung adenocarcinoma. VATS technique to perform classical anatomical segmentectomies is well defined and even in highly experienced teams, these procedures can be performed by uniportal VATS. However, the achievement of unusual central anatomical segmentectomies through Uniportal VATS remains a challenge. We describe a feasible and reproducible technique to perform uniportal VATS right lower lateral and posterior (S9–10) anatomical segmentectomy for the treatment of early stage lung cancer.

Unusual anatomical segmentectomies are technically demanding procedures that require a deep knowledge of intralobar anatomy and surgical skill. In the other hand, these procedures preserve more normal lung parenchyma for lesions located in specific anatomical segments, and are indicated for benign lesions, metastasis and also early stage adenocarcinomas without nodal involvement. A 32-year-old woman was diagnosed of a benign pneumocytoma in the anterior segment of the left-lower lobe (S8, LLL), so we performed a single-incision video-assisted thoracoscopic surgery (SI-VATS) anatomical S8 segmentectomy in 140 minutes under intercostal block. There were no intraoperative neither postoperative complications, the chest tube was removed at 24 hours and the patient discharged at 5th postoperative day with low pain on the visual analogue scale (VAS). Final pathologic exam reported a benign sclerosant pneumocytoma with free margins. The patient has recovered her normal activities at 3 months completely with radiological normal controls at 1 and 3 months.

Thoracic trauma is a challenging situation with potential severe chest wall and intrathoracic organ injuries. We present a case of emergent surgery in a 23-year-old man with hemorrhagic shock due to massive lung and chest wall injury after thoracic trauma in a water slide. We performed a SI-VATS approach in order to define intrathoracic and chest wall injuries, and once checked the extension of the chest wall injury, we added a middle size thoracotomy just over the affected area in order to stabilize rib fractures with Judet plates, that had caused massive laceration in left lower lobe (LLL) and injured the pericardium causing myocardical tear. After checking bronchial and vascular viability of LLL we suggested a lung parenchyma preserving technique with PTFE protected pulmonary primary suture in order to avoid a lobectomy. Chest tubes were removed on 3rd postoperative day and patient was discharged on 14th postoperative day. He has already recovered his normal activity 6 months after surgery.

Nowadays, sublobar anatomic resections are gaining momentum as a valid alternative for early stage lung cancer. Despite being technically demanding, anatomic segmentectomies can be performed by uniportal video-assisted thoracic surgery (VATS) approach to combine the benefits of minimally invasiveness with the maximum lung sparing. This procedure can be even more complex if a combined resection of multiple segments from different lobes has to be done. Here we report five cases of combined and unusual segmentectomies done by the same experienced surgeon in high volume institutions to show uniportal VATS is a feasible approach for these complex resections and to share an excellent educational resource.

In recent years, the search for a less invasive and thus, less painful approach has driven technical innovation in modern thoracic surgery. In this context, subxiphoid uniportal approach has emerged as an alternative to avoid intercostal space manipulation and decrease postoperative pain and intercostal nerve chronic impairment. Subxiphoid uniportal major lung resections have been safe and effective procedures when performed by experienced surgeons even in complex cases or unexpected intraoperative situations. We present six of these surgical scenarios such as big tumors, incomplete or absent fissures, hiliar calcified lymph nodes, active bleeding and massive adhesions to show the feasibility of subxiphoid approach to manage even these conditions.

Worldwide accepted indications of anatomical segmentectomies are mainly early stage primary adenocarcinomas, pulmonary metastasis and benign conditions. Their performance through uniportal VATS has become more and more popular due to the less invasiveness of the whole procedure under this approach. Recently, many efforts have focused on non-intubated spontaneously breathing management of lobectomies and anatomical segmentectomies, although specific selection criteria and main advantages are not completely standardized. In a 62-year-old thin man with two pulmonary residual metastasis from sigma adenocarcinoma, after chemotherapy plus antiangiogenic treatment, we indicated a single-incision video-assisted left-lower lobe (LLL) upper segmentectomy (S6) under spontaneous breathing and intercostal blockade. Total operation time was 240 minutes. Chest tube was removed at 24 hours and the patient was discharge on postoperative day 2 without any complication. Non-intubated uniportal VATS is a safe and reasonable approach for lung-sparing resections in selected patients, although more evidence is required for selecting which patients can benefit more over standard intubated procedures.

ResumenEl desempeño social empresarial (CSP, por sus siglas en inglés) ha sido un tema ampliamente estudiado en el campo de la administración. Sin embargo, su método de medición continúa siendo ambiguo, genera controversia y, al mismo tiempo, es complejo para la investigación. Este trabajo propone la medición del CSP, definido como la satisfacción de los stakeholders, a través de las redes sociales. Consideramos que la satisfacción de los stakeholders puede ser entendida utilizando elementos de la teoría de justicia organizational, particularmente en lo referente al uso de la expresión de voz de los stakeholders ante un evento de injusticia por parte de las empresas. El crecimiento de las redes sociales, y específicamente de los microblogs, ha permitido que las personas puedan expresar su opinión respecto a los eventos económicos, sociales, políticos y ambientales de cualquier tipo de empresa. Probamos nuestras ideas utilizando la metodología de estudio de eventos con una muestra de 5 440 datos provenientes de diez empresas; se encontró evidencia de la sensibilidad a estos eventos en las redes sociales.AbstractCorporate social performance (CSP) has been studied extensively by management scholars, yet most approaches to its measurement continue to be ambiguous, controversial and difficult to research. In this paper, we propose measuring CSP via the construct of stakeholder satisfaction through social media. Using organizational justice theory, we argue that the satisfaction of stakeholder expectations can be understood partly through the perception of unjust corporate behavior, which is then expressed by stakeholders through social media. The explosion of social networking and microblogging has made it possible for people to express opinions with respect to the economic, social, and environmental events for all sorts of firms. We test these ideas using event study methods with a sample of 5,440 observations from ten firms. We find preliminary evidence of the sensitivity of social media to these events.

Non-intubated VATS (NI-VATS) is a novel approach that aims to benefit the patient by obtaining the minimal surgical and anaesthetic invasion. In the last years, NI-VATS approach has shown encouraging results to treat primary spontaneous pneumothorax (PSP). The aim of this review is sumarize the experience of the authors developing a programme of NI-VATS surgery for treatment of PSP from 2013 to 2019 and to summarize the evidence about NI-VATS PSP treatment in the literature.

I read with enthusiasm the paper of Wang and colleagues (1) about the use of nasal high-flow oxygen therapy during non-intubated thoracoscopic surgery. The aim was to assess if high-flow oxygen therapy improved oxygenation and carbon dioxide wash out during non-intubated thoracic surgery.

In recent years, the video-assisted thoracic surgery (VATS), and uniportal VATS approach has become the routine approach in numerous centers. Nevertheless, uniportal VATS learning curve is a challenge even for those surgeons with experience in multiportal VATS surgery. Among the surgeons who prefer the use of the multiportal VATS approach it is noteworthy that many of them are more comfortable through several ports because they feel this approach is more ergonomic. We present our routine programme of VATS surgery assisted by articulated arm (AVATS) for major resections, as a technique that allows ergonomic surgery for both, surgeon and first assistant and cooperative surgical field when is needed.

Mediastinal anesthesia for diagnostic or therapeutic procedures can present more risks during the induction phase due to potential respiratory or cardiovascular collapse for direct compression by the mediastinal mass. The anesthesiologist must assess some preoperative features of patients (including patients symptoms) before initiating the procedure and categorized them into risk groups. Awake induction under local anesthesia and spontaneous breathing can be mandatory in high risk patients. Management of the airway in these patients can be a real challenge, thus different airway intubation strategies must be kept in mind before initiating the induction of anesthesia including selective endobronchial tubes under fiberoptic guidance, rigid bronchoscope jet ventilation and tracheal stenting. Cardiopulmonary by-pass might be needed if predicted great vessels invasion or if cardiovascular or respiratory collapse appears. Although non-intubated procedures are becoming more frequent for pulmonary surgical procedures, there is still a lack of evidence of its advantages and disadvantages in mediastinal surgery, so special care must be taken before embarking in this novel approach. Most severe complications after miastenia gravis surgery appear in terms of postoperative myasthenic crisis, that should first be predicted by the anesthesiologist during preoperative assessment. Short and middle action neuromuscular blocking agents can be safely used in reduced dosis, and sugammadex seems to reverse effectively and safely their action in a very short time.

Nonintubated procedures have widely developed during the last years, thus nowadays major anatomical resections are performed in spontaneously breathing patients in some centers. In an attempt for combining less invasive surgical approaches with less aggressive anesthesia, nonintubated uniportal video-assisted thoracic surgery (VATS) lobectomies and segmentectomies have been proved feasible and safe, but there are no comparative trials and the evidence is still poor. A program in nonintubated uniportal major surgery should be started in highly experienced units, overcoming first a learning period performing minor procedures and a training program for the management of potential crisis situations when operating on these patients. A multidisciplinary approach including all the professionals in the operating room (OR), emergency protocols and a comprehensive knowledge of the special physiology of nonintubated surgery are mandatory. Some concerns about regional analgesia, vagal block for cough reflex control and oxygenation techniques, combined with some specific surgical tips can make safer these procedures. Specialists must remember an essential global concept: all the efforts are aimed at decreasing the invasiveness of the whole procedure in order to benefit patients' intraoperative status and postoperative recovery.
