Filter by:Surgery plays an important role in the treatment of anterior mediastinum disease. The major surgical approaches include: cervical approach, mid-sternal approach, cervical combined mid-sternal approach and video-assisted thoracoscopic approach. The cervical approach is rarely adopted because of its restricted visual field. The cervical combined mid-sternal approach have a broader field of vision, given this advantage, the surgeon can remove the thymus and its surrounding fat tissue more thoroughly. But the trauma of this approach is much larger, and the postoperative complication is also a serious problem. The video-assisted thoracoscope is often adopted by left or right approach, this minimally invasive procedure can not remove anterior mediastinum fat thoroughly. In clinical practice, the investigators designed a new method named "3-Hole" subxiphoid approach. This study is designed to compare the safety and validity between this new method and others.
Video-assisted thoracoscopic extended thymectomy (VATET) is a minimally-invasive method for excision of mediastinal mass instead of open thymectomy. The iatrogenic capnothorax with one-lung ventilation during VATET may cause hemodynamic instability due to the compression of intrathoracic structures. The purpose of this study is to evaluate the effects of capnothorax on the pulmonary blood flow and cardiac function during the VATET by using the transesophageal echocardiography.
The study has been designed to evaluate the clinical application of the new virtual bronchoscopy (VB) -based system for transbronchial sampling of the mediastinal masses or enlarged lymph nodes. The software uses data from thorax CT scan and enables airway segmentation and reconstruction simultaneously with predefined mediastinal targets. The most suitable sites for transbronchial needle aspiration are displayed on the internal surface of the airways showed in VB mode. The diagnostic yield of the new system-assisted TBNA will be compared to the reference method (EBUS-TBNA). The study group includes patients with mediastinal mass or lymph node enlargement in whom diagnostic bronchoscopy and TBNA can be applied as diagnostic methods. Both, virtual bronchoscopy guided transbronchial needle aspiration (VB-TBNA) and EBUS-TBNA of the mediastinal targets are performed during the same diagnostic bronchoscopy. Cytologic material from VB-TBNA and EBUS-TBNA is evaluated by two independent pathologists blinded to the method used to obtain the sample. Diagnostic yield and adequacy of aspirates obtained with the two methods will be assessed and compared.
The aim of the study is to compare the performance characteristics of EUS-FNA 22 Gauge needle and EUS FNA 25 Gauge needle in terms of cellularity and diagnostic yield for diagnosis of various pathologies, including lymph nodes, pancreatic, luminal and other lesions outlined by EUS.
The purposes of this study are: - To determine the overall response rate of patients treated with at least 2 cycles of this regimen. - To determine the feasibility and toxicity of the combination of topotecan and docetaxel.
The study evaluates the efficacy and tolerability of alternating short cycles of high-dose and conventional chemotherapy in combination with rituximab in CD20 positive patients, followed by local radiation therapy in the case of initial mediastinal or central nervous system (CNS) involvement or a residual tumor after chemotherapy. A dose-reduced regimen is offered for patients estimated to be over 55 years, biologically.
