The surgical treatment of advanced non-small-cell-lung-cancer (NSCLC) invading mediastinal organs and great vessels is still controversial. The aim of this multicentre study is to analyse oncological ...outcomes, surgical outcomes and prognostic factors of patients with NSCLC involving heart and great vessels.
362 patients treated surgically for locally advanced T4-NCSLC between 1990 and 2020 were retrospectively reviewed. Patients were divided into five subgroups: pulmonary artery(n = 129), left atrium(n = 82), superior vena cava(n = 80), aorta(n = 43), and multiple vascular structures(n = 28). Resection was complete in 327(90%) patients.
Overall 90-day mortality was 8.8%, influenced by poly-transfusions, pneumonectomy, bronchopleural fistula and previous cardiovascular disease (4.5HR.p = 0.03, 3.7HR p = 0.01, 14.0HR.p < 0.001 and 3.0HR p < 0.01). One-, 3- and 5-year survival rates were 75%, 43%, 33%, respectively and there were significant differences among the five groups(p < 0.001). Survival was significantly affected by induction radiotherapy, nodal status, pTNM-stage and radicality (3.8HR p = 0.03, 2.6HR p = 0.001, 1.6HR p < 0.05 and 1.6HR p < 0.05).
Surgery provided acceptable results in selected patients with T4-NSCLC with major vascular infiltration in expert centres. Nodal-status and radicality influenced the overall-survival and disease-free survival. Neoadjuvant chemotherapy appears to have a positive effect on long-term results, particularly in N2-patients.
Thymomas are rare epithelial tumors of the mediastinum with relatively good prognosis compared to other thoracic malignancies. Surgery is considered the best treatment and the most important ...determinant of long-term survival even in advanced stages. Nevertheless, complete resection may be challenging and require a multimodality approach. We present a case of a stage IVa thymoma surgically treated. The superior vena cava was completely occluded and, after resection, reconstruction was deemed unnecessary due to sufficient venous return through the azygos-inferior vena cava system. In our opinion, despite the morbidity of surgery in advanced thymomas, it should always be considered in expert hands.
A video-assisted right pneumonectomy is a challenging but feasible procedure in expert hands. This video tutorial presents in detail the indications for and the individual surgical steps needed to ...safely perform a biportal video-assisted right pneumonectomy. In selected patients, this technique guarantees the same oncological results in terms of the perioperative outcome as those achieved by minimally invasive surgery.
Left-side secondary carina resection and reconstruction is a rare, complex procedure, performed just in a few specialized centers in a restricted group of patients. Few studies describe this ...technique and report its short and long-term results. We reviewed our experience to evaluate the perioperative and short-term outcomes of a very demanding surgery. We retrospectively collected the information of all the patients who underwent secondary carina resection and reconstruction for low-grade malignant bronchial tumors at our center. Between January 2012 and September 2018, 23 patients received surgery for low-grade malignant bronchial tumors. In all patients, a secondary carina resection and reconstruction with total lung parenchymal preservation was performed. The mean age was 44.5 ± 12.2 years. Pathologies included adenoid cystic carcinoma in ten patients, carcinoid in 7 (6 typical and 1 atypical), mucoepidermoid carcinoma in 4, myoepithelioma in 1 and inflammatory myofibroblastic tumor in 1. The median length of the resected bronchus was 25 mm (range 15–50 mm). Three patients (13%) had, at least, one postoperative complication with no deaths. Two patients had lymph node metastases and eight had positive margins. Nine patients received adjuvant therapy. Follow-up ranged from 13 to 96 months, all patients are currently alive and free of recurrence. Resection and reconstruction of the left secondary carina with preservation of the lung parenchyma can be performed safely in anatomically and oncologically appropriate patients, providing good short-term results when combined with adjuvant therapies.
Purpose
Post-sternotomy dehiscence and mediastinitis remains a serious complication in cardiothoracic surgery. The aim of this work is to report our experience over a period of 8 years in the ...surgical treatment and risk factor analyses of post-sternotomy dehiscence and mediastinitis.
Methods
All patients treated for post-sternotomy dehiscence at our Thoracic Surgery Unit in the last 8 years were retrospectively collected. We identified 237 patients with post-sternotomy dehiscence/mediastinitis. Forty-two patients had simple fractures of the metal steel wires, 61 had an asymmetric sternotomy with multiple sternal fractures, 113 had a symmetric sternotomy with multiple sternal fractures, 14 had a failed Robicsek procedure, and 7 had sternal dehiscence with mediastinal abscess.
Results
Different surgical techniques and materials were used to repair the sternum. In 21 patients, the first revision failed and a second reoperation was required. At multivariate analyses, we have identified risk factors for revision failure and in-hospital mortality. Mortality rate was significantly higher in patients who underwent more than one surgical revision (8% vs 19%,
p
< 0.001).
Conclusions
Patients with sternal dehiscence are very fragile due to multiple preoperative comorbidities as reflected by postoperative morbidity and risk factors for in-hospital mortality. A correct evaluation of the characteristics of sternal dehiscence is important to guide the most appropriate repair strategy. Patients who need repeated sternal revisions had a higher mortality. Further randomized studies are needed to evaluate different techniques and medical devices to define the
gold standard
procedure to reduce significantly sternal wound complications in high-risk patients as defined by well-known risk factors.
Many new surgical techniques and materials have been introduced in the last decade for chest wall reconstruction or stabilization with the purpose of improving the incorporation, maintaining chest ...wall stability with reduction of infections. However, none of them are yet considered a gold standard procedure. The aim of this work is to evaluate the initial experience using a new titanium mesh for chest wall reconstruction in four Italian Thoracic Surgery Departments.
A review was performed of all patients undergoing chest wall reconstruction using a new titanium mesh between January 2014 and September 2018. Surgical indications, the location and size of the chest wall defect, intraoperative variables and postoperative complications were analyzed.
A total of 26 consecutive patients were included. The most common indications for surgery were primary or secondary chest wall tumors (38%) followed by lung cancer invading chest wall (31%). The most common localization of chest wall defect was anterolateral (46%). Sternal reconstruction was required in 3 patients (12%). The average size of the defect was 9.3×7.8 cm. The median number of resected ribs was 3.6. No perioperative deaths occurred. Mean hospital stay was 11.9 days. Overall morbidity was 19%. One failure of reconstruction (4%) was reported during follow up.
In our early clinical experience chest wall reconstruction using titanium mesh can be performed as a safe and effective surgical procedure. This mesh has excellent biomechanical characteristics between rigid and malleable materials, it's easy to trim and fix for optimal adaptation without necessity of dedicated instruments. The early and mid-term results are satisfactory with low incidence of complications related to the titanium mesh implant.
Peripheral vein catheterization is generally considered a harmless procedure. Venous catheter rupture associated with pulmonary embolism is an unlikely but potentially serious complication. We report ...a case of a peripheral venous catheter (PVC) fracture with pulmonary artery embolization in the left lower lobe treated successfully by a surgical approach. The positioning of a PVC is not always a harmless procedure. Every time there are difficulties in positioning or in removal of a catheter device, it should be carefully inspected to verify integrity. The advisability of removal of these small foreign bodies is debated; percutaneous retrieval is preferred, while surgery should be discussed case by case.
A rare and complex procedure, total lung sparing left secondary carinal resection and reconstruction is only performed in a few specialized centers in a restricted group of patients. We reviewed our ...experience to evaluate its safety.
Patients who underwent left secondary carinal resection and reconstruction with complete lung parenchymal preservation for low-grade bronchial malignancies at the Shanghai Chest Hospital and the Padua University Hospital were retrospectively reviewed. Clinicopathologic factors and perioperative outcomes were analyzed.
Thirty patients underwent the procedure between July 2012 and July 2019 (mean age, 42.9 years). No operative mortality occurred and postoperative complications developed in 4 patients (13.3%), including pneumonia (n = 3 10.0%), subcutaneous emphysema (n = 2 6.7%), and prolonged air leak (n = 2 6.7%). Pathologies included adenoid cystic carcinoma (n = 11), mucoepidermoid carcinoma (n = 6), carcinoid tumors (n = 9 8 typical and 1 atypical subtypes), inflammatory myofibroblastic tumor (n = 3), and myoepithelioma (n = 1). The margins were positive in 8 patients (26.7%), whereas 2 patients (6.7%) had positive lymph nodes. Adjuvant therapies were performed postoperatively, including chemoradiotherapy for positive lymph nodes and radiotherapy for positive margins.
Total lung sparing left secondary carinal resection and reconstruction can be performed safely in well-selected and oncologically appropriate patients with low-grade bronchial malignancies.
Abstract
OBJECTIVES
The aim of this study was to evaluate a new self-expanding tract sealant device, designed to prevent pneumothorax after computed tomography (CT)-guided lung biopsy, as an ...intraoperative marker for small pulmonary nodules or ground-glass opacities during minimally invasive thoracic surgery.
METHODS
Three patients with pulmonary nodules underwent CT-guided biopsies in our radiology department. During the same procedure, using a 19-gauge coaxial needle, a self-expanding tract sealant device was positioned in the lung nodule to be used not only for the prevention of pneumothorax but also as an intraoperative marker. A few days later, conventional thoracoscopic surgery was scheduled. A visual examination was performed. The site of the deployment of the BioSentry device was determined by checking for the proximal end of it beyond the visceral pleura. Thoracoscopic wedge resections using endoscopic staplers were performed to confirm histological characteristics, surgical margins and correct placement of the plug.
RESULTS
Three consecutive patients underwent CT-guided placement of this self-expanding tract sealant device (BioSentry) before surgery, without complications. The thoracoscopic resection was performed with success. The plug was easy to visualize with the scope, and all removed nodules had surgical free margins and the plug was correctly positioned in all patients.
CONCLUSIONS
The self-expanding tract sealant device was created for the reduction of pneumothorax and chest tube placement rates after percutaneous lung biopsy. We used it for the first time for intraoperative localization of peripheral small solid nodules or ground-glass opacities with good results.
