Esophageal Dilation in Dallas & Sachse, TX

What Is Esophageal Dilation?

Esophageal dilation is a therapeutic procedure that gently stretches a narrowed section of the esophagus — the muscular tube that carries food and liquids from the throat to the stomach. Narrowing of the esophagus, known as a stricture, can make swallowing difficult, painful, or both, a condition physicians call dysphagia. Left untreated, esophageal strictures can lead to weight loss, malnutrition, food impaction (food becoming lodged in the esophagus), and aspiration (food or liquid entering the airway).

During esophageal dilation, your gastroenterologist uses specialized dilating instruments — either a balloon dilator or a series of graduated bougie dilators — to carefully widen the narrowed area. The procedure is typically performed during an upper endoscopy (EGD), which allows the physician to directly visualize the stricture, assess its severity, and perform the dilation under real-time guidance. In many cases, biopsies are also taken during the same procedure to help determine the underlying cause of the stricture.

Esophageal dilation is one of the most commonly performed therapeutic procedures in gastroenterology. The American College of Gastroenterology (ACG) and the American Society for Gastrointestinal Endoscopy (ASGE) include esophageal dilation in their clinical guidelines for the management of esophageal strictures caused by gastroesophageal reflux disease (GERD), eosinophilic esophagitis, radiation therapy, and other causes.

At Texas Gut Health in Sachse, TX, Dr. Jaison John performs esophageal dilation using advanced endoscopic techniques in a comfortable outpatient setting. Dr. John completed his gastroenterology fellowship at UT Medical Branch, where he served as Chief Fellow, and his internal medicine residency at UT Austin Dell Medical School, where he served as Chief Resident. He holds dual board certifications from the American Board of Internal Medicine in both internal medicine and gastroenterology.

What Causes Esophageal Strictures?

Esophageal strictures develop when the lining of the esophagus becomes damaged and scar tissue forms, narrowing the passageway. The most common causes include:

• Gastroesophageal reflux disease (GERD) — Chronic acid reflux is the most common cause of esophageal strictures, sometimes called peptic strictures. Years of acid exposure damages the esophageal lining, leading to inflammation, scarring, and gradual narrowing. The ACG estimates that peptic strictures occur in approximately 7% to 23% of untreated GERD patients.
• Eosinophilic esophagitis (EoE) — This chronic, immune-mediated condition causes eosinophils (a type of white blood cell) to accumulate in the esophageal lining, leading to inflammation, rings, and strictures. EoE is increasingly recognized as a major cause of dysphagia and food impaction, particularly in younger adults.
• Barrett's esophagus — This precancerous condition, a complication of chronic GERD, involves changes to the cells lining the lower esophagus. Barrett's esophagus can be associated with stricture formation and requires ongoing surveillance.
• Radiation therapy — Radiation treatment for cancers of the head, neck, chest, or upper abdomen can cause esophageal inflammation and stricture formation, sometimes months or years after treatment is completed.
• Caustic ingestion — Accidental or intentional ingestion of corrosive substances (strong acids or alkalis) can cause severe esophageal burns and strictures.
• Post-surgical strictures — Strictures can develop at surgical anastomosis sites (where two sections of the GI tract are connected) after esophageal or gastric surgery.
• Medication-related injury (pill esophagitis) — Certain medications, when they become lodged in the esophagus, can cause localized ulceration and eventual stricture formation. Common culprits include doxycycline, potassium chloride, alendronate, and NSAIDs.
• Esophageal cancer — Malignant strictures can result from esophageal cancer or cancers that invade or compress the esophagus. Dilation may be performed as a palliative measure to improve swallowing in patients with malignant obstruction.

What to Expect

Esophageal dilation is performed as an outpatient procedure, typically during an upper endoscopy. Here is what the experience looks like at Texas Gut Health.

Before Your Procedure

Preparation for esophageal dilation is the same as preparation for an upper endoscopy:

• Fasting: Do not eat or drink anything for at least 8 hours before the procedure (typically nothing after midnight the night before). An empty stomach is essential for safe sedation and clear visualization of the esophagus.
• Medication adjustments: Inform Dr. John about all medications you take. Blood thinners (such as warfarin, clopidogrel, or direct oral anticoagulants) may need to be temporarily stopped or adjusted before the procedure to reduce bleeding risk. Do not stop any medication without specific instructions from your physician.
• Transportation: Because you will receive intravenous sedation, you must arrange for a responsible adult to drive you home. You will not be permitted to drive for the remainder of the day.

During the Procedure

The combined upper endoscopy and dilation typically takes 15 to 30 minutes:

• Sedation: You will receive intravenous sedation to keep you comfortable and relaxed. Most patients fall into a light, twilight-like sleep and do not feel or remember the procedure.
• Endoscopic examination: Dr. John will pass a thin, flexible endoscope through your mouth and into the esophagus to visualize the stricture and assess its length, diameter, and characteristics.
• Dilation: Depending on the type and severity of the stricture, Dr. John will use one of two dilation techniques:
  • Balloon dilation (through-the-scope): A deflated balloon catheter is passed through the endoscope and positioned within the stricture. The balloon is then inflated with water to a precise pressure, gently stretching the narrowed area. This technique allows real-time endoscopic visualization during dilation.
  • Bougie dilation (Savary or Maloney dilators): A series of progressively larger, tapered dilators are passed over a guidewire through the stricture to gradually stretch the esophagus. This technique is commonly used for longer or more complex strictures.
• Biopsies: If the cause of the stricture has not been established, Dr. John may take tissue biopsies during the same procedure to evaluate for conditions such as eosinophilic esophagitis, Barrett's esophagus, or malignancy.

After Your Procedure

After the procedure, you will be monitored in a recovery area for approximately 30 to 60 minutes as the sedation wears off:

• Throat soreness: It is common to experience mild soreness in the throat or a sensation of chest pressure for 1 to 2 days after dilation. This is normal and typically resolves without treatment.
• Diet: You will be advised to eat soft foods for the remainder of the day and gradually resume your normal diet over the following 24 to 48 hours. Avoid hard, crunchy, or large pieces of food immediately after the procedure.
• Results: Most patients notice improved swallowing within hours of the procedure. Dr. John will discuss the findings and any biopsy results with you, typically within 1 to 2 weeks.
• Follow-up dilations: Some strictures, particularly those caused by chronic conditions like GERD or eosinophilic esophagitis, may recur over time and require additional dilation sessions. Dr. John will create a personalized follow-up plan based on the cause and severity of your stricture.

Conditions Treated with Esophageal Dilation

Esophageal dilation is used to treat narrowing and swallowing difficulties caused by a range of conditions:

• Peptic strictures from GERD — The most common indication for esophageal dilation. Chronic acid damage causes fibrous scarring that narrows the esophageal lumen.
• Eosinophilic esophagitis (EoE) — EoE-related strictures and rings are a leading cause of food impaction and dysphagia in young adults. Careful dilation combined with medical treatment of the underlying inflammation can provide significant relief.
• Schatzki rings — A thin, ring-shaped narrowing at the junction of the esophagus and stomach that can cause intermittent dysphagia, particularly with solid foods. A single dilation session is often curative.
• Barrett's esophagus — Strictures associated with Barrett's esophagus may require dilation to facilitate ongoing endoscopic surveillance and improve symptoms.
• Post-surgical anastomotic strictures — Narrowing at surgical connection sites following esophageal, gastric, or bariatric surgery.
• Radiation-induced strictures — Strictures caused by radiation therapy for head, neck, or chest cancers.
• Esophageal webs — Thin, membranous growths that partially obstruct the esophageal lumen, sometimes associated with iron-deficiency anemia (Plummer-Vinson syndrome).

Risks and Benefits

Esophageal dilation is a well-established procedure with a strong safety profile. Understanding both the benefits and risks helps patients make informed decisions about their care.

Benefits

• Rapid symptom relief: Most patients experience noticeably improved swallowing within hours of the procedure, often immediately.
• Minimally invasive: Dilation is performed endoscopically and does not require surgery, incisions, or hospitalization.
• Outpatient convenience: The entire procedure, from arrival to discharge, typically takes less than 2.5 hours.
• Diagnostic and therapeutic: The underlying cause of the stricture can be evaluated (through endoscopic visualization and biopsy) and treated in the same session.
• Repeatable: For recurrent strictures, dilation can be safely repeated as often as needed to maintain adequate swallowing function.

Risks

Serious complications from esophageal dilation are uncommon. The most significant risks include:

• Perforation: A tear in the esophageal wall is the most serious potential complication of dilation. This occurs in less than 0.5% of dilation procedures, according to published ASGE guidelines. If a perforation occurs, it may require hospitalization, antibiotics, and in rare cases, surgical repair.
• Bleeding: Minor bleeding at the dilation site is common and usually self-limited. Significant bleeding requiring intervention is rare.
• Chest pain or soreness: Mild chest discomfort or throat soreness after dilation is common and expected. It typically resolves within 1 to 2 days.
• Adverse reaction to sedation: Complications from sedation are infrequent and are monitored for by the care team throughout the procedure.
• Stricture recurrence: Some strictures, particularly those caused by chronic inflammation (GERD, EoE), may recur and require additional dilation sessions. Treating the underlying cause is essential for reducing recurrence.

Dr. John discusses all risks and benefits with each patient during the pre-procedure consultation. The ACG and ASGE affirm that esophageal dilation is a safe and effective treatment for esophageal strictures when performed by a trained gastroenterologist.
