Endoscopic Studies I: Bronchoscopy and Thoracoscopy

871
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 Studies II: Thoracocentesis

1.9K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Summary

Strain elastography, a real-time ultrasound technique, effectively distinguishes benign from malignant lymph nodes. Preliminary data suggest its feasibility during endobronchial ultrasound (EBUS) for guiding biopsies in cancer patients.

Area of Science:

  • Medical imaging
  • Diagnostic tools
  • Tissue characterization

Background:

  • Elastographic techniques offer advanced capabilities for tissue characterization.
  • Strain elastography, a real-time ultrasound (US) method, is valuable for differentiating benign and malignant lymph nodes (LNs).

Purpose of the Study:

  • To review preliminary data on the feasibility of real-time elastography during endobronchial US (EBUS).
  • To explore the potential application of elastography for selecting LNs for EBUS-guided transbronchial needle aspiration (TBNA) in cancer patients.

Main Methods:

  • Review of preliminary data on real-time elastography integrated with endobronchial ultrasound.
  • Assessment of strain elastography for lymph node characterization during EBUS procedures.

Main Results:

  • Strain elastography shows feasibility for real-time application during EBUS.
  • Potential utility for selecting lymph nodes for EBUS-guided TBNA in lung and extrathoracic malignancies.

Conclusions:

  • Real-time elastography during EBUS is feasible.
  • This technique may improve the selection of lymph nodes for biopsy in cancer patients, enhancing diagnostic accuracy.
