Endoscopic Studies I: Bronchoscopy and Thoracoscopy

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...

Endoscopic Studies II: Thoracocentesis

Endoscopic Studies II: Thoracocentesis

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

This study explored two novel intrapleural applications of single-use bronchoscopes in cadavers. Both techniques proved feasible, offering potential complementary methods for intrathoracic space visualization.

Area of Science:

Thoracic Surgery
Minimally Invasive Procedures
Medical Device Technology

Background:

Conventional methods for intrathoracic space visualization have limitations.
Single-use bronchoscopes offer potential for novel applications in pleural procedures.

Purpose of the Study:

To evaluate the feasibility of two intrapleural applications of single-use bronchoscopes in a cadaveric model.
To assess the safety and technical aspects of these novel bronchoscopic techniques.

Main Methods:

Approach 1: Utilized a 2.7 mm bronchoscope as a visual stylet within a 20-Fr trocar catheter for pleural entry and drain-tip confirmation.
Approach 2: Employed a 5.0 mm bronchoscope as a flexible thoracoscope for limited pleural inspection, aspiration, and biopsy.

Main Results:

Approach 1 was feasible in six hemithoraces across three cadavers.
Approach 2 was feasible in four hemithoraces; it was not attempted in two due to time and a persistent air leak after Approach 1.
No new persistent air leaks were observed after Approach 2.

Conclusions:

The studied intrapleural applications of single-use bronchoscopes are feasible in a cadaveric setting.
These techniques may complement existing methods for intrathoracic visualization.
Further clinical validation is warranted to assess their utility in patient care.
