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...

Summary

A novel transcervical endoscopic approach allows safe and effective access to the visceral mediastinum for lymph node harvest and esophageal myotomy. This minimally invasive technique shows high success rates for mediastinal surgery.

Area of Science:

Minimally invasive surgery
Thoracic surgery
Endoscopic procedures

Background:

Traditional mediastinal surgery uses transthoracic or transabdominal approaches.
The transcervical approach offers direct access to pre- and paratracheal regions.
Extending this approach to the retro- and paraesophageal mediastinum requires investigation.

Purpose of the Study:

To evaluate the feasibility, safety, and success of transcervical flexible endoscopy for mediastinal surgery.
To assess its utility in the retro- and paraesophageal mediastinal spaces.

Main Methods:

Performed transcervical mediastinal operations on pigs and a human cadaver using flexible endoscopes.
Utilized endoscopic ultrasound (EUS) for lymph node marking.
Created connective tissue tunnels with balloon dilatation and CO2 insufflation for esophageal dissection.
Conducted Heller myotomy and targeted lymph node harvest.

Main Results:

100% success in esophageal dissection to the diaphragm.
100% success in performing distal esophageal myotomy.
100% success in harvesting marked lymph nodes (16/16 in pigs, 2/2 in cadaver).
One case of tension pneumomediastinum in the pig group.

Conclusions:

The transcervical approach with flexible endoscopes provides successful access to the entire visceral mediastinum.
Directed lymph node harvest and esophageal myotomy are feasible with high success rates.
Connective tissue tunnels are a safe and promising method for mediastinal exploration.
