Filter by:Recently, probe based confocal laser endomicroscopy showed to be able to distinguish malignant from benign pleura during medical thoracoscopy. However The clinical usefulness of this new tool remains to be determined. The investigators believe that pCLE could be part of mini invasive pleural disease management and could be used during thoracentesis in order to increase the diagnostic yield of this procedure. The investigators are starting a prospective trial to recruit patients referred for medical thoracoscopy to the endoscopy unit. First, the pCLE probe will be introduced through the Boutin's needle or the thoracentesis catheter, just before the thoracoscopy, in order to investigate the pleural pCLE features and to identify or exclude malignant infiltration. Second those features will be compared to the pCLE acquisition obtained during the medical thoracoscopy (the probe is introduced through the working chanel of the thoracoscope), under visual control. In order to compare the invasive and mini invasive acquisition, 10 criteria will be prospectively assessed.Third, These features will be compared to the histological samples performed during thoracoscopy. Finally, the interpretation of different investigators will be compared. The 10 criteria are presented below: 1. Abnormal tissular architecture No: Correct identification of the previously described normal pleura characteristics Yes: identification of cellular/tissular structures which are not known to correspond to normal pleura (cellular clusters or dark clumps, glands, cells cordons, dysmorphic cells, papillar distribution….) 2. Cellular homogeneity is size, shape and fluorescence, as subjectively assessed by the investigator yes no 3. Mean cellular size: Small: < 10µm Moderate: 10 - 20µm Large: > 20µm 4. Cellular density (with reference to the Chia seed sign) Low (lower than the Chia seed sign) Moderate High 5. Dysplastic vessels: Yes: (vascular leaks, tortuous or giant vessels) No: no dysplasia 6. Vascular density (on a full optical area) Low: 0 -2 vessels Moderate: 3 - 4 vessels High: > 4 vessels 7. Organized or anarchic connective fibers Anarchic: coarse fibers, irregular in shape, without well-defined architecture Organized : regular in shape and direction, well defined architecture. 8. Chia seed sign on a full optical areal yes No
Video-Assisted thoracic surgery (VATS) is the standard treatment for localized lung cancer. However, there is no consensus on analgesic management in patients undergoing VATS. The aim of the study is to compare the analgesic efficacy of thoracic epidural with that a "Bi-block" combining an Erector Spinae muscle plane Block (ESP) and a Serratus Anterior Block (SAP) in patients undergoing VATS for lung or pleural surgery. Our main hypothesis is that the analgesic efficacy of the Bi-block, assessed by morphine consumption, is not inferior to that provided by a thoracic epidural during the first 48 hours after VATS. We conducted a age, gender and type of surgery-matched retrospective cohort study in the Department of Thoracic Anesthesia of the Montpellier University Hospital (France).
Background: The Pleura is a double-layered membrane that surrounds the lungs. Pathological processes that involve the Pleura are called "Pleural diseases". Among them are included Pneumothorax (Air the chest cavity), Pleural effusions, and tumor formation. Ultrasound imaging of the Pleura to detect and assess pleural diseases has been proven as an excellent diagnostic and safe option. Ultrasound test uses sound waves to characterize the structure and function of different organs in health and disease. The standard technique used to create two-dimensional ultrasound picture is called Delay and Sum (DAS). Signals are transmitted and received from a series of elements and allow a two dimensional picture to be created. Because a large number of sensors is required, creating a two dimensional picture creates a large and usually redundant data pool. This fact leads to a need for stronger processors and larger operating systems, Consumption of higher energy, and hence an ungainly, slow, and expensive system. Signal Acquisition Modeling and Processing Laboratory (SAMPLE) in Weizmann institute has developed a data processing system that allows narrowing down the number of elements needed to process the ultrasound signal, while creating an ultrasound picture of abdominal organs in a satisfying resolution. Sometimes even better than standard methods. Research goal: Improvement of diagnosis and characterization of pleural diseases by Ultrasound, using a novel algorithm that was developed in SAMPLE laboratory in Weizmann Institute. The aim is to create a faster, more reliable ultrasound imaging while minimizing sampling rate and data volume. Methods: Tested population: Women and/or men who were diagnosed with Pneumothorax or Plural effusion with other imaging modalities, and healthy volunteers as a control group, Up to 30 participants per each group (Total up to 90), in a 1:1:1 Ratio. Research type: An open-labeled study. Experimental design: Participants that will meet the required conditions will be summoned to an exam in our imaging institute or will be scanned bedside, using the Verasonics ultrasound system, which allows free access to ultrasound raw Channel data. The information acquired, as well as other imaging scans of the participant, will be coded and delivered anonymously to SAMPLE laboratory for analysis.
The study will be carried out by the principal investigator and his team at the Division of Cardiovascular and Thoracic Surgery of the Department of Surgery, College of Medicine, University of Ibadan and the University College Hospital, Ibadan (UCH), which is the Teaching Hospital of the Medical College.The study sets out to prospectively compare the early and long-term outcomes between the use of purse-string (suturing U-technique) and Un-reapproximated thoracostomy wound edges (Occlusive adhesive-absorbent dressing application) at the time of removal of thoracostomy tube drain in patients who have had chest tube insertion.
The diagnosis, treatment and mechanism of pleural diseases
This study will be a prospective, randomized trial comparing a new protocol to the standard of care. The investigators protocol and the standard of care involves a previously established procedure that will be completed in the investigators pulmonary procedure unit. The study will include using previously, well-established procedures (indwelling pleural catheter placement, talc slurry administration through an indwelling pleural catheter, pleuroscopy with talc poudrage administration) in addition to a new protocol (at home continuous drainage via indwelling pleural catheter).
Pleural disease i.e. with effusions or pneumothorax have a high disease burden to patients. This is because most patients require diagnostic and therapeutic interventions in the form of drainage and biopsies. With increasing age, the incidence of pleural disease is likely to rise with concomitant rise in pulmonary malignancy and infection. The impact of pleural disease, especially ambulatory drainage depends not only on patient factors such as effusion size, cardiopulmonary co-morbidities and underlying aetiology. It also depends on socioeconomic factors such as ability to afford ambulatory equipment (which is not covered by Medisave), availability of care-givers and coping mechanisms. To phenotype patients presenting to Singapore General Hospital with pleural disease and evaluate impact on outcomes of pleural interventions This study will collect existing or prospective data that is part of standard clinical care - Source of the data: electronic medical record of patients (ambulatory and inpatient) - Data will be collected prospectively.
This phase I trial studies the side effects and how well light dosimetry system works during photodynamic therapy with porfimer sodium in treating participants with malignant mesothelioma , non-small cell lung cancer or any other malignancy with pleural disease undergoing surgery. Light dosimetry measures the amount of laser light given during photodynamic therapy. Photodynamic therapy uses a drug, such as porfimer sodium, that becomes active when it is exposed to light. The activated drug may kill tumor cells. Using light dosimetry for intraoperative photodynamic therapy may help doctors estimate how much light is delivered during photodynamic therapy and decide if the treatment should be stopped or continued.
The primary objective of this prospective trial will be to assess the effects of dexmedetomidine administration on oxygenation and respiratory function in patients undergoing diagnostic or therapeutic medical thoracoscopy/pleuroscopy for a pleural effusion compared to conventional conscious sedation/monitored anesthesia care (MAC) with midazolam. The secondary endpoint of the study will be to also assess the effects of dexmedetomidine administration on respiratory mechanics and postprocedural complications
The purpose of this study is to determine if there are any differences in terms of safety, pain, or drainage speed between thoracenteses via manual drainage vs vacuum suction.
