A peptic esophageal stricture (narrowing of the esophageal lumen) is one of the late complications of gastroesophageal reflux disease and occurs in 1% to 5% of patients who develop esophagitis (irritation and inflammation of the lining of the esophagus). It is one of the most difficult complications of gastroesophageal disease to manage.
Peptic esophageal stricture is caused by severe gastroesophageal reflux disease and continuous damage of the lining of the esophagus by the stomach acid refluxing into the esophagus, resulting in scar and narrowing of the lumen of the esophagus.
Patients may present with both typical (common) and atypical (uncommon) symptoms of reflux, but dysphagia (difficulty swallowing) and regurgitation of food after eating are the main symptoms.
Many patients succeed in relieving most if not all the symptoms of GERD by making lifestyle and diet changes. Other patients require medications to control symptoms.
Other procedures used to treat peptic esophageal stricture include:
The stricture can be dilated by using esophageal dilators, using bougies (plastic tubes that are passed from the mouth into the esophagus to dilate the esophagus) or balloon dilators during an upper endoscopy. The procedure may need to be repeated multiple times. The complete control of gastroesophageal reflux will help healing of the stricture. Aggressive acid suppression therapy with proton pump inhibitors has reduced the incidence of strictures. Despite this advance in therapy, 30% of patients with strictures require a repeat dilation within one year.
Esophageal stents are a relatively safe and effective method of palliation (improvement of symptoms) and treatment of peptic esophageal strictures.
In patients who do not respond to medications and multiple esophageal dilation, surgery should be considered. The most efficient method of treating a reflux stricture has been dilation followed by an antireflux procedure to obtain complete control of gastroesophageal reflux. The aim of the surgical treatment is to restore the function of the lower esophageal sphincter (the valve between the esophagus and the stomach), to prevent the reflux of acid and bile (non-acidic juice) from the stomach into the esophagus and help healing of the stricture. The most common procedure to restore the function of the lower esophageal sphincter and prevent the gastroesophageal reflux is a minimally invasive procedure called laparoscopic Nissen fundoplication.
Strictures associated with severe esophageal dysmotility (non functional esophagus) are extremely difficult to manage. In some extreme cases, esophagectomy (esophageal replacement) may be needed.
