Abstract:
We describe tracheoesophageal common channel formation in a 40-year-old woman who swallowed alkaline detergent. Necrosis and fistula formation between the posterior tracheal wall and the anterior esophageal wall were visualized by panendoscopy 15 days after the injury. Urgent tracheostomy, tube hypopharyngostomy, gastrostomy, and feeding jejunostomy were performed. Tracheoesophageal common channel formed by anterior tracheal wall and posterior esophageal wall was visualized by bronchoscopy at 48 days after the injury. Progression was observed by a panendoscopy, bronchoscopy, and chest computed tomography. Sequelae included trismus, obliteration of laryngopharynx, proximal cervical esophagus, and thoracic esophagus below the carina, stomach stricture, and scarring of the scalp, neck, back, and thighs.

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...
Esophageal Perforation-I: Introduction
The location of esophageal perforation can vary, occurring anywhere along the esophagus.
Barrett Esophagus-I: Introduction
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

Tracheostomy Decannulation
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...
