How does esophageal stricture occur in elderly individuals?

Generally, esophageal stricture in elderly individuals may be caused by congenital developmental abnormalities, age-related degeneration, esophageal spasm, reflux esophagitis, or esophageal leiomyoma. Treatment options include general management measures and medication therapy, as directed by a physician. Detailed explanations are as follows:

1. Congenital Developmental Abnormalities

Congenital developmental abnormalities refer to structural anomalies of the esophagus that arise during embryonic development, such as esophageal rings or webs. These abnormalities may lead to narrowing of the esophageal lumen. Dietary adjustments are recommended in daily life, avoiding excessively hard or irritating foods.

2. Age-related Degeneration

With advancing age, the muscular and elastic layers of the esophagus gradually weaken, resulting in reduced elasticity of the esophageal wall and subsequent narrowing. Lifestyle modifications include avoiding lying down immediately after meals and consuming soft or liquid foods.

3. Esophageal Spasm

Esophageal spasms may be triggered by abnormal nerve regulation, emotional fluctuations, or food-related stimuli. These spasms may cause temporary or persistent narrowing of the esophageal lumen, potentially leading to associated symptoms such as nausea and vomiting. Medications such as sustained-release nifedipine tablets, nitroglycerin tablets, or fixed-dose combinations of flupentixol and melitracen may be prescribed by a physician for treatment.

4. Reflux Esophagitis

Reflux esophagitis occurs when gastric contents, including gastric acid, flow back into the esophagus. Long-standing reflux esophagitis may lead to mucosal damage and fibrosis of the esophagus, resulting in esophageal narrowing. Symptoms may include progressive dysphagia and acid regurgitation. Treatment typically involves medications such as omeprazole enteric-coated capsules, mosapride citrate tablets, or hydrotalcite chewable tablets, as directed by a physician.

5. Esophageal Leiomyoma

Esophageal leiomyomas may be triggered by genetic factors, abnormal hormone levels, or chronic irritation. These benign tumors grow within the esophageal wall and may occupy space within the lumen, causing esophageal narrowing. Symptoms may include dysphagia and food regurgitation. If significant compressive symptoms develop, surgical removal of the leiomyoma—剥离 (dissection) of the esophageal leiomyoma from the esophageal wall—may be considered under medical guidance.

To prevent and improve esophageal stricture, elderly individuals should adjust their diet, opting for soft or liquid foods while avoiding excessively hard or irritating foods. Maintaining healthy eating habits, including avoiding lying down immediately after meals, can also help reduce the burden on the esophagus.
