Abstract:
A 74-year-old man presented for outpatient endoscopy because of dysphagia and the sensation of a mass in the back of his throat. Esophagogastroduodenoscopy demonstrated a soft tissue mass in the proximal esophagus that prolapsed into the hypopharynx on withdrawal of the endoscope. Complete airway obstruction ensued, requiring emergent tracheotomy. The patient was transferred to the hospital for further treatment. Surgical resection revealed a rare giant fibrovascular polyp, which may be associated with asphyxiation and sudden death.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
Endotracheal Intubation I: Procedure
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

Endotracheal Tube Extubation
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals....

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...
