Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

328
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...

The Bronchial Tree

4.6K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Endoscopic Studies II: Thoracocentesis

822
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...

COPD: Pathogenesis and Clinical Features

1.5K
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists01:18

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

278
Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

Pulmonary Hypertension: Classification and Pathogenesis

400
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Summary

Benign endobronchial tumors, though rare, are often diagnosed via endobronchial resection. These well-defined lesions can cause obstructive symptoms, but treatment yields excellent survival outcomes.

Area of Science:

  • Pulmonology
  • Thoracic Surgery
  • Pathology

Background:

  • Benign endobronchial tumors are uncommon and challenging to diagnose due to nonspecific symptoms and vague imaging.
  • Accurate diagnosis and effective treatment are crucial for managing these rare airway lesions.

Purpose of the Study:

  • To review the clinical, radiologic, and pathologic features of benign endobronchial tumors.
  • To analyze diagnostic methods and treatment strategies for these tumors.
  • To evaluate patient outcomes and survival rates following treatment.

Main Methods:

  • Retrospective analysis of 28 patients with biopsy-proven benign endobronchial tumors from 1993-2018.
  • Review of clinicopathologic and radiologic data, focusing on treatment modalities and survival.
  • Data collection on tumor types, presenting symptoms, imaging findings, and surgical interventions.

Main Results:

  • Hamartoma was the most frequent type (37%), followed by lipoma (19%).
  • Common symptoms included cough (58%), shortness of breath (44%), and hemoptysis (15%).
  • Endobronchial resection was the preferred diagnostic and therapeutic approach, with no reported deaths.

Conclusions:

  • Benign endobronchial tumors typically present as well-defined submucosal or pedunculated lesions.
  • These tumors can lead to post-obstructive complications, necessitating timely intervention.
  • Endobronchial resection is the optimal strategy for diagnosis and treatment, ensuring favorable patient survival.
