Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

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 to...

COPD: Management Using Bronchodilators and Corticosteroids

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
Computed Tomography01:10

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Oxygen Delivering System III: Tracheostomy and T-piece01:23

Oxygen Delivering System III: Tracheostomy and T-piece

Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Summary
This summary is machine-generated.

Optical coherence tomography (OCT) combined with bronchoscopy is feasible for airway evaluation. OCT provides high-resolution images of tracheal microanatomy, similar to histology.

Area of Science:

  • Pulmonary Medicine
  • Medical Imaging
  • Endoscopy

Background:

  • Conventional bronchoscopy is a key tool for airway examination.
  • Histology provides detailed microanatomical information but is invasive and not feasible in real-time.
  • There is a need for advanced imaging techniques to complement bronchoscopy.

Purpose of the Study:

  • To assess the feasibility of integrating optical coherence tomography (OCT) with conventional bronchoscopy.
  • To evaluate the potential of this combined approach for detailed airway evaluation.

Main Methods:

  • A pilot study using an ex vivo animal model (rabbit and pigs).
  • An OCT imaging catheter was advanced through the working channel of a flexible bronchoscope.
  • High-resolution cross-sectional images of the trachea were acquired in real-time.

Main Results:

  • The OCT catheter integrated seamlessly with the bronchoscope's working channel.
  • Real-time, high-resolution images clearly delineated tracheal microstructures (epithelium, submucosa, cartilage, adventitia).
  • Distinct visualization of tracheal wall layers, including the trachealis muscle, was achieved.

Conclusions:

  • Combining OCT with flexible bronchoscopy is feasible for airway imaging.
  • OCT provides detailed microanatomical insights into the trachea, comparable to histology.
  • This technique holds potential for enhanced endoscopic airway evaluation.
