16 hours ago · Stricture formation can be due to inflammation, fibrosis, or neoplasia involving the esophagus and often posing damage to the mucosa and/or submucosa. An esophageal stricture refers to the abnormal narrowing of the esophageal lumen; it often presents as dysphagia, commonly described by patients as difficulty swallowing. >> Go To The Portal
Appropriate management depends on identifying the correct etiology for stricture. The majority of esophageal strictures result from benign peptic stricturesfrom long-standing gastroesophageal reflux disease (GERD), which accounts for 70 to 80% of adult cases.[1]
Patients with malignant esophageal strictures have a thicker esophageal wall on EUS, with a loss of wall stratification compared to patients with benign esophageal strictures, who demonstrate preservation of wall stratification more frequently.
Strictures due to caustic esophagitis or eosinophilic esophagitis, however, are more common in children and young patients. Strictures related to acid reflux, iatrogenic or drug-induced esophagitis, on the other hand, are more common in adults. Malignant strictures are found in older people, as cancer prevalence is higher in older populations.

530.3 - Stricture and stenosis of esophagus is a topic covered in the ICD-10-CM.
Potential complications of benign esophageal stricture Dense and solid foods can lodge in the esophagus when it narrows. This may cause choking or difficulty breathing.
Treatments include:dilation – enlarging the stricture with gradual stretching.urethrotomy – cutting the stricture with a laser or knife through a scope.open surgery – surgical removal of the stricture with reconnection and reconstruction, possibly with grafts (urethroplasty)
Esophageal dilation is the most recommended esophageal stricture treatment. The doctor uses a balloon or dilator — a long cylinder made of rubber or plastic — to widen the esophagus. The doctor gives you sedatives before the procedure to relax you and may numb parts of your throat, so you don't feel pain.
Esophageal stenosis (esophageal stricture) is a tightening or narrowing of the esophagus, the tube that brings liquid and food from the mouth to the stomach. The condition is caused by chronic inflammation, surgical procedures, trauma, cancer, radiation, or can be present at birth (congenital).
A Schatzki's ring is a ring of tissue that forms inside the esophagus, the tube that carries food and liquid to your stomach. This ring makes the esophagus narrow in one area, close to where it meets the stomach. It can make it hard to swallow. You may feel like food gets stuck in your esophagus.
ICD-10 code K20. 9 for Esophagitis, unspecified is a medical classification as listed by WHO under the range - Diseases of the digestive system .
As discussed above, strictures of the esophagus can cause obstruction which can lead to presentation to the emergency room. Strictures can be benign or malignant in etiology.
When food gets stuck in your esophagus from a severe stricture you may vomit. If this happens you may need immediate treatment. Doctors can diagnose strictures with a barium esophagram. Additionally, the barium esophagram outlines the size and location of the stricture or strictures in your esophagus.
More than 80–90 % of esophageal strictures can be treated successfully with endoscopic dilation using Savary bougies or balloons.
In young children and adolescent populations, corrosive substance ingestion is the leading cause of stricture formation in the esophagus.[2] The following classification and list of common and uncommon causes for stricture formation in the esophagus can guide physicians in their approach to management:
Stricture formation can be due to inflammation, fibrosis, or neoplasia involving the esophagus and often posing damage to the mucosa and/or submucosa. An esophageal stricture refers to the abnormal narrowing ...
Anastomotic Stricture: Certain early-stage esophageal cancers and head & neck cancers are managed with an esophagectomy with a high end-esophagogastrostomy or bowel loop interposition. Such procedures have a postoperative risk of anastomotic stricture formation at the anastomosis; this can occur in 22 to 50% of cases and often require repeat endoscopic interventions to dilate the stricture due to high recurrence rates. [16]][17]
Stricture development is a common consequence of ingesting such as toxic substances. [4][5] Eosinophilic esophagitis (EoE): It represents a distinct chronic, local immune-mediated esophageal disease clinically characterized by dysphagia and histologically by eosinophilic-predominant inflammation.
Treatments include the use of dilators, stent placement, surgical resection, and medical management. The technique most utilized for benign stricture management is endoscopic dilation using a bougie or a balloon dilator. The main objective is to improve symptoms, mainly in relieving patients of dysphagia.[33] In clinical practice, treatment outcome is evaluated by a dysphagia scoring system. Ogilvie et al. first introduced such a scoring system, but they applied it in the context of esophageal malignancy palliated with stent placement to relieve dysphagia. However, it has application to almost all types of benign and malignant stricture management situations.[34] The following describes the clinical dysphagia scoring system:
Endoscopy affords an opportunity for therapeutic dilation of the stricture when indicated. Contrast fluoroscopy is only for those patients who have a complex stricture or when endoscopy is incomplete due to excessive narrowing of the lumen. Choosing a water-soluble contrast agent for first-pass viewing is advised here to avoid inspissation of heavy agents such as barium and thereby minimizing the risk for obstruction and/or aspiration.
The normal esophagus measures up to 30 mm in diameter . A stricture can narrow this down to 13 mm or less, causing dysphagia. The pathophysiology of stricture development differs based on the underlying etiology, but the basic pathological changes include damage to the mucosal lining.
TBIn the past, peptic strictures (ie, strictures related to reflux) of the distal esophagus were fairly common; however, such strictures are no longer prevalent, most likely because antireflux therapy has become very effective and is widely used . Currently, the most common causes of benign strictures of the esophagus are anastomotic strictures, which can develop following resection of the distal esophagus and proximal stomach for treatment of esophageal cancer or Barrett esophagus, and radiation-induced strictures, which frequently develop following treatment of head and neck cancer. In the latter patients, the strictures are located very proximally in the esophagus. Other causes include aggressive treatments for Barrett esophagus (such as photodynamic therapy) and nasogastric tube injury.
The other reason that these strictures are more difficult to manage is their location. Because they are found very high in the esophagus, there is not much room , if any, in which to place a stent above the stricture; in some patients, the stent must be placed above the cricopharyngeus, which is generally considered a contraindication to stent placement.
TBThe diameters of balloons are measured in millimeters, whereas some bougie dilators are measured using the “French” gauge system , which has been used for hundreds of years. French gauge is a measure of circumference, which is π × diameter (in millimeters). French gauge is sometimes referred to as Charriere gauge, after the French surgical instrument maker who invented it. Three French equal 1 millimeter; thus, a 20-mm dilator equals 60 French. Bougie dilators range in size from 5mm to 20 mm; esophageal dilating balloons range from 6mm to 20 mm, though the catheters upon which they are mounted may be as small as 5 French (approximately 2 mm). In addition, balloons are available with 3 inflation sizes (eg, 10, 11, and 12 mm; or 14, 15, and 16 mm, depending upon inflation pressure).
Insertion complications include airway compromise from compression, aspiration, and complications related to sedation. Transient pain, nausea, and vomiting are not uncommon. As previously mentioned, stents often migrate, as their covering prevents tissue embedding. Although stent covers should prevent damage, there have been several cases of stricture development at the contact points of the stent ends upon stent removal. Thus, although the original stricture resolves, the ends of the stents may create new strictures. It is unclear whether these new strictures occur because these patients are more susceptible to stricture formation. However, this complication is uncommon. Granulation tissue has also been found in some patients; a benign growth develops around the stent but resolves upon stent removal because the growth was merely an irritation caused by the stent. Some authors have also noted the development of tracheoesophageal fistulas and bleeding from stent-induced ulcers.
For example, if I started with a 9-mm dilator, I would next use a 10-, 11-, and 12-mm dilator, and so on, until I feel resistance to the passage of the dilator. The first dilator that causes resistance to passage counts as “one.” The rule of three states that only 2 additional dilators of sequential size should be passed (3 dilators in total). Thus, a physician should not skip dilator sizes (eg, a 10-mm dilator met with resistance should not be immediately followed by a 14-mm dilator).
On the other hand, balloon dilators can pass through a stricture without requiring removal of the endoscope and are mounted on small-diameter catheters, which allows passage through very tight strictures, where bougie dilators may not be able to pass.
In addition, when stents are placed very proximally, patients often feel a foreign body sensation as well as pain.
Esophageal strictures are a problem commonly encountered in gastroenterological practice and can be caused by malignant or benign lesions. Dysphagia is the symptom experienced by all patients, regardless of whether their strictures are caused by malignant or benign lesions.
Brachytherapy has been shown to be beneficial in patients with an expected survival of longer than 3 months with regard to (prolonged) dysphagia improvement, complications and quality of life. The mainstay of benign esophageal stricture treatment is dilation. Although dilation usually results in symptomatic relief, recurrent strictures do occur.

Treatment. Dilation (stretching) of the esophagus using a thin cylinder or balloon that is inserted through an endoscope is the main treatment for acid reflux-related strictures. You may need to have this treatment repeated after a period of time to prevent the stricture from narrowing again.
Benign esophageal stricture is a narrowing of the esophagus (the tube from the mouth to the stomach). It causes swallowing difficulties. Benign means that it is not caused by cancer of the esophagus. A solution containing a dye (barium), which is visible on x-rays, has been swallowed (upper GI series) and x-rays have been taken of the esophagus.
The digestive system organs in the abdominal cavity include the liver, gallbladder, stomach, small intestine and large intestine.
Solid food, especially meat, can get stuck above the stricture. If this happens, endoscopy would be needed to remove the lodged food.
