Filter by:Objectives: The main drawback of the hook-wire technique for locating ground glass nodules before video assisted thoracoscopic surgery (VATS) resection is the risk of the hook dislodging during single lung ventilation as the lung collapses. In order to reduce the friction of the thread in the wall, the investigators modified the technique by first positioning a catheter in the chest wall and introducing the carrying needle through the catheter. The objective was to evaluate the success rate and complications of this technique. Material and Methods : the investigators retrospectively included all patients undergoing VATS resection of solitary lung nodules after localization using the sliding wire technique.
The primary objective is to evaluate the performance parameters of the proposed DLAD (Carebot AI CXR) in comparison to individual radiologists.
With the increasing acceptance of routine computed tomography (CT) screenings, early-stage lung cancer detection is becoming more frequent. For ground glass opacity predominant early-stage lung cancer, segmentectomy can get the same oncological benefits as lobectomy. In addition, lung nodules that are highly suspected to be metastases can also be performed by segmentectomy to preserve more lung function. During the surgery, the rapid and precise identification of the intersegmental plane is one of the challenges. The improved inflation-deflation method is currently the most widely used method in clinical practice. According to the dispersion coefficient of the gas, the rapid diffusion properties of carbon dioxide would be expected to speed lung collapse and so facilitate surgery. The purpose of this study was to investigate the feasibility and safety of carbon dioxide on the appearance time of satisfactory and ideal planes during segmentectomy.
A monocentric prospective and randomized trial aiming to compare the diagnostic yield and safety of electromagnetical-guided bronchoscopy (ENB) procedures coupled to trans-bronchial lung cryobiopsies for the diagnosis of pulmonary nodule when performed either in a "standard" bronchoscopy suite or in a hybrid room with CBCT guidance and the use of the CrossCountry technique as required.
In pulmonary oncology, the diagnosis of medium-sized pulmonary nodules (10 to 20 mm), too distal to be reached by standard bronchial fibroscopy but remaining proximal, is difficult. There are 2 techniques: transthoracic puncture-biopsy under CT scan, usually performed by radiologists, and distal sampling guided by radial ultrasound mini-probe. The limitations of the last technique could be overcome by the use of cryoprobes for sampling, as they would take more tissue by freezing.
This study is a retrospective multi-center chart review of patients who underwent an attempted biopsy of one or more pulmonary lesion(s) with the Ion Endoluminal System with the aim of assessing the overall performance of the system.
The investigators aimed to compare the pre-post operative effects of video-assisted thoracoscopy surgery (VATS) and thoracotomy on pulmonary function, exercise capacity, physical activity level, respiratory and peripheral muscle strength, inspiratory muscle endurance, quality of life, fatigue, dyspnea perception and pain in patients with pulmonary nodules.
The goal of this study is to collect post-market data for the Ion Endoluminal System to understand CT to body divergence.
The standard procedure in the diagnosis of peripheral round foci is bronchoscopy with transbronchial forceps biopsy (TBB). Despite the simultaneous application of X-ray fluoroscopy, the diagnostic value of this method depends strongly on the size, location and relationship of the foci to the airways as well as their radiological representability. By inserting radial 20 MHz ultrasound probes through the working channel of a flexible bronchoscope into the periphery of the lung, the detection of peripheral foci can be improved. By simultaneously using a virtual bronchoscopy with an ultra-thin bronchoscope, even smaller round foci in the periphery of the lung can be detected. For some years now, tension-resistant cryoprobes have been used for transbronchial biopsy. Here, especially in lesions that can only be reached endoscopically tangentially, advantages have been shown over forceps biopsy. Much larger tissue samples can be obtained without increasing the complication rate. Studies showed that the combination of the EBUS navigation technique with the cryobiopsy procedure is feasible and safe in the endoscopic diagnosis of peripheral lung tumors. This study investigates to what extent the combination of an ultra-thin cryoprobe with an ultra-thin bronchoscope together with the radial EBUS can further improve the diagnosis. This study is a non-randomized pilot study to prove the feasibility of this procedure. The EBUS probe and the bronchoscope are CE certified for this application. The study will be conducted as a monocentric study at the Thorax Clinic at Heidelberg University Hospital. A total of 30 patients with an indication for transbronchial biopsy will be prospectively included. All patients will be examined according to the clinical standard. After a freezing time of 3-7 seconds, the probe together with the bronchoscope will be extracted and the sample will be defrosted in a water-filled sample vial. Up to 4 biopsies will be taken depending on the investigator's assessment. The samples will be collected separately and the order of the biopsies will be recorded. The primary endpoint is the feasibility of the procedure. Secondary endpoints are safety, diagnostic hit rate, biopsy size and quality and success rate depending on the position of the EBUS probe (tangential or central).
The primary objectives of this study are to assess the sensitivity and specificity of SGM-101 in detecting non-small cell lung carcinomas during surgery when excited by an near-infrared light source utilizing intraoperative imaging.
