Esophageal Strictures-II: Clinical Features and Management

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...

Trachea

Trachea

The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of the...

Esophageal Strictures-I: Introduction

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
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...

Tracheostomy Decannulation

Tracheostomy Decannulation

Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Esophageal Achalasia

Esophageal Achalasia

Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...

Summary

Posterior glottic stenosis (PGS) is a complex airway condition. Surgical interventions like grafting are effective for treatment and voice restoration in most patients.

Area of Science:

Otolaryngology
Surgical Pathology

Background:

Posterior glottic stenosis (PGS) is a complication of prolonged intubation.
It can mimic bilateral vocal cord paralysis and requires specific surgical approaches.

Purpose of the Study:

To summarize the experience with posterior glottic stenosis (PGS) and its diagnostic workup.
To evaluate surgical interventions and outcomes for PGS.

Main Methods:

Retrospective review of adult patients with PGS operated between 1994 and 2006.
Inclusion of laryngeal electromyographic studies and direct laryngoscopy since 2000.
Surgical interventions included endoscopic laser, laryngofissure with or without grafts, and cricoid split with stenting.

Main Results:

Ten patients diagnosed with PGS; 6 had additional laryngotracheal stenosis.
Seven patients were successfully decannulated within 1-3 procedures.
Voice quality was good in 7 patients, serviceable in 2, and aphonic in 1.

Conclusions:

Posterior glottic stenosis can be isolated or part of complex laryngotracheal pathologies.
Electromyographic studies and direct laryngoscopy are crucial for diagnosis.
Grafting with costal cartilage or buccal mucosa is safe and effective for subglottic remodeling.
