Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

1.8K
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...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

832
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...

Area of Science:

  • Thoracic Surgery
  • Surgical Oncology
  • Pulmonary Medicine

Background:

  • Anatomical segmentectomies are crucial for lung cancer resection, especially for ground-glass opacities and deep metastatic tumors.
  • Virtual assisted lung mapping (VAL-MAP) is an innovative bronchoscopic technique using multi-spot dye markings and 3D virtual images to guide surgical resection.
  • VAL-MAP enhances thoracoscopic segmentectomies, including complex variations like combined subsegmentectomies and extended segmentectomies.

Conclusions:

  • Virtual assisted lung mapping (VAL-MAP) is a valuable tool for anatomical segmentectomies in lung cancer surgery.
  • It simplifies complex segmentectomies and improves the precision of stapling techniques.
  • This technique offers significant advantages for oncological lung resections, particularly in challenging anatomical situations.
