Esophagus stricture

uncommon, secondary to esophagitis, lead dvlp of scar tissue of submucosa prevent passage of normal food bolus

cause:

• Post-anesthetic stricture (most common).
• severe chemical irritation from gastric acid or medications – doxycycline and clindamycin
• Traumatic foreign bodies

CS

• regurgitation-most common, regurgitate within second after meal, start to gag and show discomfort within second of eating before forcefully regurgitating the ingesta
•  generally regurgitate every meal

(For megaesophagus, who may eat a normal meal and then regurgitate after minutes to hours)

Diagnosis

Endoscopy-full visualization of the extent and number of any strictures, as well as an assessment of the degree of concurrent esophagitis.

(Feeding barium mixed with food may reveal a focal esophageal dilation but the number and extent of any strictures caudal to the first obstruction is difficult to assess)

Treatment:

requires dilation of the stricture and prevention of recurrence

Endoscopic balloon dilation is the most widely accepted treatment.

 balloon is passed into the stricture and inflated to a pre-determined pressure to exert a radial force and break down the scar tissue.
