Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Pulmonary Function Tests

Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...
Endoscopic Studies II: Thoracocentesis01:26

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...
Radiological Investigation II: MRI and Ventilation Perfusion Scan01:30

Radiological Investigation II: MRI and Ventilation Perfusion Scan

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Area of Science:

  • Oncology
  • Pulmonary Medicine
  • Surgical Assessment

Background:

  • Lung cancer is a leading cause of cancer death globally.
  • Lung resection is the sole curative treatment for lung cancer.
  • Only 15-25% of lung cancers are operable at diagnosis, often requiring significant lung tissue removal.

Purpose of the Study:

  • To review current standards for preoperative assessment in lung cancer patients.
  • To highlight the importance of evaluating pulmonary function before lung resection.
  • To identify strategies for minimizing risks associated with lung resection in patients with compromised pulmonary reserves.

Main Methods:

  • Review of current literature on preoperative assessment for lung cancer surgery.
  • Analysis of guidelines and best practices for pulmonary function testing.
  • Synthesis of evidence regarding risk stratification and management of patients undergoing lung resection.

Main Results:

  • Preoperative assessment is crucial for identifying patients at risk of respiratory disability post-lung resection.
  • Standardized pulmonary function tests are essential for evaluating lung function.
  • Careful patient selection and optimization are key to successful surgical outcomes.

Conclusions:

  • Optimizing preoperative assessment can reduce the incidence of permanent respiratory disability after lung resection.
  • Adherence to current standards ensures better patient selection and surgical planning.
  • Further research may refine preoperative assessment protocols for lung cancer patients.
