Unusual Periaortic Mediastinal Recurrence of Pulmonary Adenocarcinoma: When Making Diagnosis Is Really Necessary.

We report an unusual mediastinal recurrence along descending thoracic aorta during oncologic follow-up in a 47-year-old female smoker issued by lung adenocarcinoma with a history of left lower lobectomy and lingulectomy en bloc followed by adjuvant chemotherapy for stage III A-N2. Regional recurrence occurring along the staple line was suspected and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) combined to PET/CT allowed to reach definitive tissue diagnosis. High focal hypermetabolic activity on PET/CT at the site of suspect recurrence was necessary to check the lesion sampling by EBUS-TBNA.

Negative-Pressure Ventilation in Neuromuscular Diseases in the Acute Setting.

Mechanical ventilation started with negative-pressure ventilation (NPV) during the 1950s to assist patients with respiratory failure, secondary to poliomyelitis. Over the years, technological evolution has allowed for the development of more comfortable devices, leading to an increased interest in NPV. The patients affected by neuromuscular diseases (NMD) with chronic and acute respiratory failure (ARF) may benefit from NPV. The knowledge of the available respiratory-support techniques, indications, contraindications, and adverse effects is necessary to offer the patient a personalized treatment that considers the pathology's complexity.

Penetrating pulmonary injury caused by a steel rod.

In stable patients with penetrating thoracic trauma, a careful radiological assessment should be taken into account for a correct surgical management.

Multiple variations in pulmonary veins during a thoracoscopic right lower lobectomy: A case report.

A knowledge of pulmonary vein anatomy variants allows an appropriate preoperative radiological assessment and safe surgical management of vascular anomalies in patients undergoing major lung resections. In our case, multiple pulmonary vein variations were identified pre- and intraoperatively in a patient undergoing thoracoscopic right lower lobectomy and included superior and common basal veins from the right lower lobe draining separately into the left atrium, middle lobe veins joining the superior segment right lower lobe vein and additional superior segment right lower lobe vein draining directly into the left atrium. The recognition of these anatomical abnormalities in pulmonary veins may help thoracic surgeons avoid surgical complications in patients undergoing anatomical lung resections.

Left lower lobectomy and partial preservation of segmental arteries of left upper lobe: A strategy to avoid pneumonectomy in selected cases.

In this article we report two cases of left lower lobe lung cancer undergoing a surgical procedure that allowed the preservation of lung parenchyma and avoided pneumonectomy. The first case concerned a left lower lobe non-small cell lung cancer with extracapsular spread in a metastatic interlobar lymph node and the second a left lower lobe lung cancer with invasion of the pulmonary artery at the origin of lobar branches to the lower lobe. In both cases, a lung-sparing surgical treatment was preferred and a left lower lobectomy was performed with division of lingular arteries and the interlobar artery, preserving the remaining arterial branches to the upper lobe.

Management of chest impalement injury.

PRESENTATION OF CASE: We will describe the case of a man who impaled himself on a greenhouse pole by falling off a ladder. DISCUSSION: The belated radiological exclusion of any spine and neck lesions forced the surgeons to operate with the patient supine and on a spine board, which prevented them from performing the classic thoracotomy and reaching the entry hole in the right scapula area. CONCLUSION: A double thoracotomy and the expedient of a haemostatic plug, positioned simultaneously with the extraction of the pole, allowed to control bleeding with absolute safety margins.

Elective surgery treatment in patient living in rural area with history of recurrent primary spontaneous pneumothorax: A procedure to avoid in absence of pneumothorax. A case report.

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.

Hybrid robotic thoracic surgery for excision of large mediastinal masses.

Between April 2016 and October 2017, we retrospectively reviewed all patients undergoing excision of large mediastinal masses using a hybrid robotic thoracic approach at the Unit of Thoracic Surgery of Monaldi Hospital in Naples. The inclusion criteria for this approach were: evident unilateral predominance of the mass; absence of invasion to surrounding structures. Planned conversion to sternotomy was necessary in one patient for tenacious adhesions between the mediastinal goiter and the left innominate vein. In all cases the postoperative course was uneventful. The hybrid robotic approach, adopted in our Unit, consists of a thoracic procedure performed completely with articulated surgical instruments under three-dimensional vision and followed by final extension of a port-site incision to retrieve the voluminous specimen. This approach uses all the advantages of robotic technology that enables to perform a fine dissection in the small space of the anterior mediastinum and at the same time, through the simple extension of a minimally invasive access, avoids the painful sequelae of thoracotomy. In selected cases, with increased experience in robotic surgery, it can be proposed for excision of large mediastinal masses, although a longer follow-up period is necessary to validate our findings.

Antero mediastinal retrosternal goiter: surgical excision by combined cervical and hybrid robot-assisted approach.

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.

Anterior bronchogenic mediastinal cyst as priority procedure for robotic thoracic surgery.

We report a case of anterior bronchogenic mediastinal cyst (ABMC) in old age patient underwent Robotic Thoracic Surgery (da Vinci Surgical System). Video-assisted thoracoscopic surgery (VATS) represents the routine approach in posterior bronchogenic mediastinal cyst, but some limitation for resection of mediastinal mass located in the anterior mediastinum has been reported. The introduction of da Vinci surgical system has overcome the surgical limits of VATS as two dimensional vision (2D) and the use of long rigid instruments with poor maneuverability in case of fine dissection.

Anterior mediastinal solitary fibrous tumor resection by da Vinci® Surgical System in obese patient.

INTRODUCTION: Solitary fibrous tumors are uncommon soft tissue tumors initially reported only in the pleura but, in recent years, they have been described at many extra pleural sites, such as mediastinum. The treatment of choice is the extensive surgical resection that is curative for most benign lesions. PRESENTATION OF THE CASE: We present the case of solitary fibrous tumor of the anterior mediastinum in obese patient (BMI: 34.3) undergoing complete surgical resection by robotic-assisted thoracoscopic surgery with da Vinci® Surgical System. DISCUSSION/CONCLUSION: Robotic-assisted thoracoscopic surgery with da Vinci® Surgical System is an interesting option for obese patient, at higher risk for deep sternal wound infection.

Caveats in using vacuum-assisted closure for post-pneumonectomy empyema.

OBJECTIVES: Vacuum-assisted closure (VAC) of chronic empyemas can potentially set challenging patients free of prolonged hospitalization by warranting outpatient care. We wanted to test this concept in post-pneumonectomy empyema patients. METHODS: Three patients with post-pneumonectomy bronchopleural fistula were subjected to open window thoracostomy (OWT) and subsequently to VAC. The BPFs were closed by endobronchial stents in 2 of the patients. The VAC system was applied at a median time of 35 days (range, 23-113) after pneumonectomy. The patients were scheduled for outpatient visits every three days with complete change of the VAC sponges. RESULTS: Hypotension and acute thoracic pain despite minimal suction applied to the VAC sponges were observed during treatment and eventually caused VAC discontinuation. In one patient, the sponges of the VAC system could not be directly removed through the OWT and careful dissection through VATS under deep sedation was needed. CONCLUSIONS: VAC can be of help to obliterate the post-pneumonectomy empyema cavity but its use can trigger clinically significant complications. Cautious monitoring of the VAC system must be exercised in the early period prior to discharging patients to the outpatient clinic.

Ultrasonographic identification of peripheral pulmonary nodules through uniportal video-assisted thoracic surgery.

PURPOSE: An intrinsic limitation of video-assisted thoracic surgery (VATS) resides in the impossibility to palpate the lung to identify embedded nodules. We wanted to investigate the use of intraoperative ultrasonography to detect pulmonary nodules during uniportal VATS. DESCRIPTION: We describe our initial experience with the identification of peripheral pulmonary nodules with an articulating ultrasound probe introduced through a single VATS incision. The instrument was used in 2 patients with solitary pulmonary nodules and previous history of extrathoracic cancer. EVALUATION: The lung nodules were identified by the articulating probe and resected on wide tumor-free margins through uniportal VATS. Subsequent lung palpation through minithoracotomy confirmed the absence of additional lesions. CONCLUSIONS: Intraoperative ultrasound scanning of the lung with an articulating probe can be successfully used through uniportal VATS to identify peripheral nodules.

Video-assisted thoracic surgery rib resection and reconstruction with titanium plate.

A 38-year-old man was diagnosed with fibrous dysplasia of the anterolateral segment of the fifth rib by core biopsy. A decision was made to resect the rib by video-assisted thoracic surgery (VATS) taking care to preserve the muscle and overlying myodermal layers. Subsequent reconstruction was done using a straight titanium plate locked in place under thoracoscopic guidance to avoid friction of the plate on the skin and to verify that the transfixed screws would not injure the lung or the pericardium. The patient made an uneventful recovery and was dismissed on day 2 after surgery. Final diagnosis confirmed fibrous dysplasia.

Surgery of the chest wall for involvement by breast cancer.

Chest wall involvement by breast cancer remains a difficult clinical challenge that may occur at the time of the primary diagnosis or later as a result of locoregional breast cancer recurrence. A case-by-case multidisciplinary approach is strongly recommended, and a multimodality therapy should be always considered. Full-thickness resection of the chest wall can be done with acceptable morbidity and mortality, providing a good palliation and a better quality of life even to patients with poor prognosis. Moreover, in well-selected cases, chest wall resection results in locoregional control of disease and prolongation of life.

Diagnostic value of carbohydrate antigens in supernatants and sediments of pleural effusions.

A panel of tumour markers including carcinoembryonic antigen (CEA), carbohydrate antigen (Ca)15-3, Ca125 and Ca19-9 were measured in the lysate of sediments and in the supernatants of pleural effusions of patients with benign and malignant disease. The tumour markers were also measured in the serum of the same patients. Of these patients, 32 had benign diseases (12 trasudative effusions associated with cirrhosis and 20 with non-malignant exudates: 12 pleuritis and 8 other inflammations) and 103 had malignant effusions (37 breast cancers, 29 lung cancers, 10 ovary cancers, 6 kidney cancers, 11 mesotheliomas and 10 lymphomas). We showed the highest level of CEA in pleural effusions of lung cancer followed by that in pleural effusions of breast cancer; whereas Ca15-3 was very high in the pleural effusions of breast and lung cancer. Concerning the lysate of sediment, CEA was high in the pleural effusions of patients with lung cancer and Ca15-3 in those of patients with breast cancer. The other markers are much less useful. For the remaining tumours, none of the markers tested appear to aid in the diagnosis of disease. In conclusion, our data suggest that the combined determination of tumour markers on supernatants and sediments of pleural effusion may provide additional information on the nature of pleural effusion, especially for cases with negative cytology.

Gelatinolytic activities (matrix metalloproteinase-2 and -9) and soluble extracellular domain of Her-2/neu in pleural effusions.

Matrix metalloproteinases (MMPs) are proteolytic enzymes that are implicated in multiple stages of cancer progression including invasion and metastasis. MMPs exert these effects by cleaving a diverse group of substrates, which include not only structural components of the extracellular matrix, but also growth factor receptors. By gelatin zymography we verified MMP activity in the pleural effusions of patients with benign and malignant disease. Of these patients, 32 had malignant pleural effusion, consisting of 20 breast cancer, 6 non-small cell lung carcinoma, 4 ovarian carcinoma, and 2 colonic adenocarcinoma, and 10 had benign pleural effusion (5 pleurisy and 5 cirrhosis). Zymography showed the constant presence of a substantial amount of MMP-2 in all samples analyzed, whereas MMP-9 was present to lesser quantities. MMP-2 activity was enhanced in pleural effusions from patients with benign diseases compared with cancer patients. MMP-9 was present in 59% of cancer patients and the lytic activity was enhanced in pleurisy and absent in cirrhosis. Furthermore, we determined the pleural effusion levels of the soluble extracellular domain of HER-2/neu. The levels of HER-2/neu ECD were above the cut-off value in breast cancer patients. No correlation between gelatinolytic activities and high HER-2/neu ECD values was found.
