Endoscopic Studies I: Bronchoscopy and Thoracoscopy

288
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...

Cardiopulmonary Resuscitation II: ACLS Airway Management

160
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Summary

Thoracic surgeons can improve lung nodule diagnosis using electromagnetic navigational bronchoscopy (ENB). Key factors for successful biopsy include nodule size and bronchus sign, aiding program implementation.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Interventional Pulmonology

Background:

  • Lung nodules are increasingly detected due to lung cancer screening.
  • Advances in transbronchial biopsy necessitate thoracic surgeon involvement in diagnostic procedures.

Purpose of the Study:

  • To report thoracic surgeon experience implementing an electromagnetic navigational bronchoscopy (ENB) program.
  • To identify predictors of successful navigation and diagnostic biopsy of lung nodules.

Main Methods:

  • Retrospective analysis of patients undergoing ENB for lung nodule evaluation (2014-2019).
  • Recursive partitioning and multivariable regression analyses were used to identify predictors.

Main Results:

  • Successful navigation was achieved in 75.8% of 91 nodules across 73 patients.
  • Bronchus sign, lesion size, and pleural distance predicted successful navigation.
  • Diagnostic biopsy was obtained in 65.2% of navigated lesions, with size ≥1.3 cm and positive bronchus sign being most predictive.

Conclusions:

  • Nodule size, pleural distance, and bronchus sign are key for ENB navigation.
  • Lesion size >1.3 cm and a positive bronchus sign are most predictive of diagnostic biopsy.
  • These factors are crucial for thoracic surgery practices implementing ENB programs.
