Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

1.1K
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Endoscopic Procedures V: ERCP

7.3K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Tracheostomy Suctioning I: Pre-Procedural Steps

3.4K
Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...

    Area of Science:

    • Medical Imaging
    • Pulmonology
    • Medical Device Technology

    Background:

    • Peripheral bronchoscopy is crucial for diagnosing lung cancer nodules but faces low diagnostic yields (14%) and physician variability.
    • Existing multidetector computed-tomography (MDCT)-based route planning for bronchoscopy is tedious, error-prone, and lacks constraint integration.
    • Current image-guided systems struggle to effectively integrate MDCT route information into live bronchoscopy procedures.

    Purpose of the Study:

    • To develop and evaluate an advanced image-guided system for peripheral bronchoscopy.
    • To improve the accuracy and efficiency of diagnosing peripheral lung cancer nodules.
    • To overcome limitations in current MDCT-based route planning and live guidance integration.

    Main Methods:

    • Developed an automatic optimal route-planning method integrating anatomical, device, and procedural constraints.
    • Implemented MDCT/video data fusion for seamless translation of route plans into live guidance.
    • Conducted an image-based study for route-planning validation and a prospective patient study for system evaluation.

    Main Results:

    • The proposed system achieved a 91% successful navigation rate to target sites in lung cancer patients.
    • Compared to a commercial system, it enabled navigation two airways deeper and reduced sampling time by nearly 2 minutes.
    • The system demonstrated high accuracy in predicting the navigable depth of bronchoscopy routes.

    Conclusions:

    • The novel image-guided system significantly enhances the feasibility and success rate of peripheral bronchoscopy for lung cancer diagnosis.
    • The integrated optimal route planning and real-time guidance fusion offer substantial benefits over existing methods.
    • This technology promises to improve diagnostic yield and patient outcomes in peripheral lung cancer detection.
