OBJECTIVES: Robotic thymectomy has been suggested and considered technically feasible for thymic tumours. However, because of small-sample series and the lack of data on long-term results, controversies still exist on surgical and oncological results with this approach. We performed a large national multicentre study sought to evaluate the early and long-term outcomes after robot-assisted thoracoscopic thymectomy in thymic epithelial tumours. METHODS: All patients with thymic epithelial tumours operated through a robotic thoracoscopic approach between 2002 and 2022 from 15 Italian centres were enrolled. Demographic characteristics, clinical, intraoperative, postoperative, pathological and follow-up data were retrospectively collected and reviewed. RESULTS: There were 669 patients (307 men and 362 women), 312 (46.6%) of whom had associated myasthenia gravis. Complete thymectomy was performed in 657 (98%) cases and in 57 (8.5%) patients resection of other structures was necessary, with a R0 resection in all but 9 patients (98.6%). Twenty-three patients (3.4%) needed open conversion, but no perioperative mortality occurred. Fifty-one patients (7.7%) had postoperative complications. The median diameter of tumour resected was 4cm (interquartile range 3-5.5cm), and Masaoka stage was stage I in 39.8% of patients, stage II in 56.1%, stage III in 3.5% and stage IV in 0.6%. Thymoma was observed in 90.2% of patients while thymic carcinoma occurred in 2.8% of cases. At the end of the follow-up, only 2 patients died for tumour-related causes. Five- and ten-year recurrence rates were 7.4% and 8.3%, respectively. CONCLUSIONS: Through the largest collection of robotic thymectomy for thymic epithelial tumours we demonstrated that robotenhanced thoracoscopic thymectomy is a technically sound and safe procedure with a low complication rate and optimal oncological outcomes.

AbstractWe report the clinical case of a patient with acute myocardial infarction due to coronary stent compression as first manifestation of a large thymoma. The patient underwent a coronarography and thrombus aspiration + plain old balloon angioplasty restoring the stent patency. The mass resection was performed through left robotic‐assisted thoracic surgery (RATS), resulting in a type A thymoma pT1a, IIb Masaoka‐Koga. An uncommon presentation led to early diagnosis and treatment of a thymoma with both oncological and functional significance.

Lung cancer is the leading cause of cancer-related death worldwide. Since prognosis of early-stage non-small cell lung cancer (NSCLC) remains dismal for common relapses after curative surgery, considerable efforts are currently focused on bringing immunotherapy into neoadjuvant and adjuvant settings. Previously, perioperative chemotherapy showed only a modest but significative improvement in overall survival. The presence of broad tumor neoantigens load at primary tumor prior to surgery as well as the known immunosuppressive status following resection represent the main rationale for immunotherapy in early disease. Several trials have been conducted in recent years, leading to atezolizumab and nivolumab approval in the adjuvant and neoadjuvant setting, respectively, and perioperative immunotherapy in NSCLC remains a field of active clinical and preclinical investigation. Unanswered questions in perioperative therapy in NSCLC include the optimal sequence and timing of chemotherapy and immunotherapy, the potential of combination strategies, the role of predictive biomarkers for patient selection and the choice of useful endpoints in clinical investigation.

Key message The identification of the accessory vein draining the superior segment of the right lower lobe (accessory V-6), during the posterior mediastinal lymph node dissection, can help avoid operative complications.

INTRODUCTION: Pneumothorax is defined as accumulation of air in the pleural space with secondary lung collapse resulting in dyspnea or chest pain. Currently the optimal management of spontaneous pneumothorax has been standardized, but the question of elective surgery treatment remains unresolved in patients living in rural area with history of recurrent Primary spontaneous pneumothorax [PSP]. PRESENTATION OF CASE: A 41 years-old white man living in rural area, with a history of recurrent right spontaneous pneumothorax (three subsequent episodes) treated by positioning of chest tube, was admitted to our unit. No respiratory symptoms and normal physical exam were observed on admission although anxiety states was noted. Chest CT scan showed small apical bullae in the right upper lobe without cystic change in the pulmonary parenchyma. DISCUSSION: Recurrence of primary spontaneous pneumothorax represents a complication most frequently occurring within the first year. Among the treatment options, surgical management is needed in 25-50% of all patients suffering from PSP, due to persistent air leak or recurrence. We report the operative complications after elective surgery in a white man living in rural area with a history of recurrent right primary spontaneous pneumothorax. CONCLUSION: This case report highlights that elective surgery in patients living in rural area with history of recurrence PSP can lead to post-operative complications as bleeding or prolonged air leaks following the lysis of multiple pleural adhesions.

Most intrathoracic goiters are located in the anterior mediastinum. Surgical resection is usually recommended in case of morbidity associated with the goiter's mass effect or for suspicion of malignancy difficult to diagnose without resection. Intrathoracic goiters are usually resected through a cervical approach, with sternotomy needed in selected cases. We report a case of antero mediastinal retrosternal goiter in old age patient undergoing surgical excision by combined cervical and hybrid robot-assisted approach. All steps of the thoracic procedure were completely performed using the da Vinci robot system with final extension of a port-site incision to extract the specimen. This approach provides more advantages than sternotomy regarding post operative clinical benefits and allows a more accurate surgical resection in the antero-superior mediastinum than conventional thoracoscopy.

BACKGROUND:Endoscopic management of tracheal stenosis may be challenging, especially in the case of complex stenosis placed near the vocal folds, and needing stent placement. Herein, we evaluated the utility of the three-dimensional (3D) airway model for procedural planning in a consecutive series of patients with complex airway stenosis and scheduled for endoscopic treatment.METHODS:This strategy was applied to 7 consecutive patients with tracheal stenosis unfit for surgery. The model was printed in a rubber-like material, and almost 7 hours were needed to create it. All patients presented respiratory failure with a mean value of 3.4±0.4 Medical Research Council (MRC) dyspnea scale, 47±3.9 forced expiratory volume in 1 second (FEV1%), and an impairment in the 6-minute walking test (6MWT) (mean value, 175±53 m). The mean length of the stenosis was 19±3.4 mm; 3 of the 7 (43%) patients presented a subglottic stenosis. In 4/7 (57%) patients the stenosis was >5 mm, but its treatment required the placement of a stent because of the presence of tracheal cartilage injury.RESULTS:The mean operation time was 22.7±6.6 minutes. No complications were observed during and after the procedure. A significant increase of MRC (3.4±0.4 vs. 1.6±0.5; P=0.003), of FEV1% (47±3.9 vs. 77±9.7; P=0.001), and of 6MWT (175±53 vs. 423±101; P=0.0002) was observed after the procedure (mean follow-up, 11.1±8.8 mo).CONCLUSION:Our 3D airway model in the management of airway stenosis is useful for procedural planning, rehearsal, and education. The fidelity level of the 3D model remains the main concern for its wider use in patient care. Thus, our impressions should be confirmed by future prospective studies.

INTRODUCTION: Most hamartomas are located peripherally in the lung parenchyma and are rarely identified as an endobronchial lesion. Clinically patients with an endobronchial hamartoma are often symptomatic and may present with various symptoms including: fever, wheezing, hemoptysis and obstructive pneumonia. CASE PRESENTATION: A 68-year-old man presented with complaints of fever and cough for 1 month. Chest X-ray revealed a right infrahilar density, which on chest CT was found to be a lesion obstructing the superior segmental bronchus of the right lower lobe and extending outside of the bronchus. A round rubbery mass obstructing the same segmental bronchus was noticed during bronchoscopy and endoscopic biopsy yielded a pathological diagnosis of hamartoma. DISCUSSION: Bronchoscopy is most helpful in diagnosis and management of endobronchial hamartomas but if the lung distal to the obstruction is irreversibly damaged or imaging studies suggest that tumor extends outside of the bronchus, pulmonary segmentectomy, lobar resection or even pneumonectomy may be indicated. CONCLUSION: When a benign tumor of the lung, as endobronchial hamartoma, is located in a segmental bronchus and presents extrabronchial spread, we recommend to perform a parenchymal-sparing surgical resection. In this case surgical team, however, should keep in mind, due to difficult individual dissection of the segmental bronchovascular elements, the possibility of conversion from VATS (video-assisted thoracic surgery) to open thoracotomy.

Several authors have reported major complications during thoracoscopic pulmonary lobectomy but a few papers have been published concerning minor adverse events. This definition in our report takes into account no life-threatening intraoperative complications managed with minimal invasive approach and with no need for conversion to thoracotomy. We retrospectively reviewed 644 patients who underwent thoracoscopic anatomic pulmonary lobectomy between April 2011 and May 2018: among these, 25 patients suffered minor intraoperative complications such as bronchial injury, stapler failure during parenchymal resection, injury to bronchial artery, oozing from vascular stump, etc. Our findings suggest that these complications don’t adversely affect the early postoperative outcomes but they still need proper management to avoid major intraoperative complications and an eventful postoperative course. The report shows that minor adverse events may occur for device malfunction but, in some instances, human errors or inadequate knowledge of technological instruments may be implicated.

Although controlled studies have demonstrated the benefits of a minimally invasive approach for pulmonary lobectomy over thoracotomy, reports have also documented that significant complications can occur during thoracoscopic lobectomy and sometimes require planned or emergent conversion to open surgery. Several authors have identified and reported causes and implications of intraoperative conversion to thoracotomy using different types of classification. The aim of this single centre retrospective review is to evaluate how the reasons for conversion change with increased experience, dividing patients who were converted to thoracotomy during video-assisted thoracic surgery (VATS) lobectomy, between 2011 and 2017, in two groups: those treated during learning curve (LC group) and those treated after learning curve (ALC group). Our research suggests that the conversion rate, with increased skills, decreases but a variety of reasons for conversion persist. Of these, calcified, benign or malignant hilar adenopathy is the most frequent and represents the leading cause of conversion to open surgery due to complicated vascular dissection or vessel injury. It's strongly recommended, with increased confidence in performing VATS lobectomies, also to develop management strategies and techniques to prevent and control possible intraoperative adverse events.

Exogenous lipoid pneumonia (ELP) is caused by the inhalation of vaporized oily products. Long-term exposure can result in chronic disease, whereas acute form usually results from massive aspiration of fatty substances. It has an incidence of 1.0%-2.5%. In case of symptomatic patients, the clinical presentation mainly includes acute or chronic respiratory symptoms such as dyspnea, fever, cough and less frequently chest pain, hemoptysis, or weight loss. Radiological findings are often aspecific or misinterpreted, and ELP is sometimes misdiagnosed as a malignancy of the lungs. Patient history and radiological findings can lead to a suspicion of ELP, but histological microscopic findings of intra-alveolar lipid and lipid-laden macrophages are required to confirm the diagnosis The mainstay of treatment consists of avoiding ongoing exposure and providing supportive care as repeated whole-lung lavage, corticosteroids, and/or immunoglobulins. Surgery is reserved for cases of high suspicion of cancer or serious clinical impact (as recurrent infections). Prognosis is benign, even if it has been reported cases of progression to severe respiratory failure, cor pulmonale, superinfection, and association with lung cancer. Here, we describe a case of ELP due to chronic inhalation of oily product (Vaseline) used as a lubricant of tracheotomy cannula.

The advantages of thymectomy as part of the treatment of myasthenia gravis has been demonstrated repeatedly in the literature. Both single-institution and multi-institution trials have shown robotic thymectomy to be safe, feasible and associated with better early clinical outcomes than the trans-sternal approach. Most reports have also documented the superiority of robotic technology in the dissection of the superior mediastinum over conventional thoracoscopy, thanks to instruments with more degrees of movement and freedom. However, in case of a vascular injury in the superior mediastinum, after an initial management with minimally invasive approach, one should not hesitate to convert to sternotomy if the bleeding control hasn't been definitely established. In this way it is possible to avoid catastrophic injuries, also in relation to the limitations that, in our opinion, the robotic surgery has once a major vascular injury occurs in the mediastinum.

Lung or lobar torsion is a very rare condition that can cause serious complications if missed or untreated. We report a case of a 72-year-old man undergoing video-assisted thoracoscopic upper bilobectomy for treatment of lung cancer. On the first postoperative day radiographic and bronchoscopic findings suggested lobar torsion and then exploratory thoracotomy was carried out within 24 hours of the initial procedure performing simple detorsion and not completion pneumonectomy for various reasons: absence of pulmonary necrosis, incomplete rotation of the bronchovascular pedicle, patient’s inability to functionally tolerate a pneumonectomy. Unfortunately the patient didn’t show clinical and radiological improvement, during the postoperative period, and he died 12 days later due to cardiorespiratory complications. This case report highlights the need for prompt intervention in patients with lobar torsion within a few hours from the onset of the phenomenon. At the same time it highlights the possibility of fatal outcome in patients unable to functionally tolerate further lung resection. To the best of our knowledge, this is the first report of lobar torsion following video-assisted thoracoscopic upper bilobectomy.

Morgagni hernia is a relatively uncommon congenital diaphragmatic hernia in which abdominal contents protrude into the chest through the foramen of Morgagni.It usually occurs on the right side of the chest but may occur on the left side or in the midline.In adults, it commonly presents with non-specific symptoms such as dyspnea, cough, gastroesophageal reflux disease and other.Surgical repair should be always performed to prevent the risk of hernia incarceration.Transthoracic approach has been proposed especially in cases with indeterminate, anterior pericardial masses.We believe that in adult obese patients with Morgagni hernia and voluminous hernial sac containing only omentum, the transthoracic approach can represent a valid alternative to transabdominal approach.The use of hybrid robotic thoracic surgery can be strongly recommended because it allows, through robotic instruments, to perform delicate surgical maneuvers in difficult to reach anatomical areas and, with the final extension of a port-site incision, to remove voluminous specimens from the thoracic cavity, avoiding the chest wall discomfort that follow the thoracotomy access.
