Filter by:The goal of this multi-center randomized clinical trial is to evaluate the added value of needle based confocal laser endomicroscopy (nCLE)-imaging to regular diagnostic bronchoscopic peripheral lung lesion analysis on the diagnostic yield in patients with peripheral pulmonary nodules suspect for malignancy. The main question[s] it aims to answer are: To determine if the addition of nCLE-imaging to conventional diagnostic bronchoscopic peripheral lung lesion analysis results in an improved diagnostic yield (defined as the proportion of patients in whom the bronchoscopic procedure results in a definitive diagnosis out of the total number of patients that have received the diagnostic bronchoscopic procedure). Participants will undergo diagnostic bronchoscopy either with or without the addition of nCLE imaging before each TBNA. Based on the feedback of the CLE images on (in)correct placement of the needle, the needle might be repositioned before sampling. Comparison between the diagnostic yield of these groups will be done including subgroup analysis.
The purpose of this study is to investigate the feasibility of using ctDNA to support cancer diagnosis and risk stratification where invasive aerosol generating testing (and/or tissue biopsy) is challenging due to infection risk, technical impracticalities and resource limitations, such as during the COVID-19 pandemic and the subsequent recovery period.
Investigators will analyze the efficacy of continuous regional anesthesia through a catheter under erector spinae muscle in a prospective, randomized, double blind, placebo-controlled study. Investigators will include 50 adults, predicted for elective lung surgery with video-assisted thoracic surgery (VATS) technique. Patients will be randomly assigned to group A or B. Investigators will insert a catheter under the erector spinae muscle (ESC) at the T4 level of the operated side under ultrasound guidance. All patients will receive an initial bolus of 20ml levobupivacaine 0,5% through the catheter. Group A will receive a continuous infusion 5ml/h of ropivacaine 0,2% and intermittent boluses of the same local anesthetic 15ml/4h through the ESC. Group B will receive a continuous infusion of 0,9% saline in the same doses. All patients will have a PCA pump with piritramide 1mg/ml to cover the pain. All patients will receive regular doses of paracetamol and metamizole as part of multimodal analgesia. Investigators will compare pain, assessed with the VAS scale in resting and coughing and piritramide usage in both groups. Investigators will compare the incentive spirometry results at 24 and 48 hours postoperatively and observe for possible late complications.
