Esophageal dilatation
Esophageal Dilatation
Esophageal dilatation (pronounced: e-sof-uh-JEE-ul dy-luh-TAY-shun) is a medical procedure used to widen a narrowed section of the esophagus. The esophagus is the tube that connects the throat to the stomach, allowing food and liquid to be swallowed.
Etymology
The term "esophageal dilatation" is derived from the Greek word "οἰσοφάγος" (oesophagos) meaning gullet, and the Latin word "dilatatio" meaning expansion.
Procedure
Esophageal dilatation is typically performed using a device known as a dilator, which is inserted into the esophagus to gradually stretch the narrowed area. This procedure is often performed under sedation to ensure the patient's comfort.
Indications
Esophageal dilatation is commonly used to treat conditions such as achalasia, esophageal stricture, and esophageal web. These conditions can cause difficulty swallowing, chest pain, and other symptoms.
Risks
Like all medical procedures, esophageal dilatation carries some risks. These can include esophageal perforation, bleeding, and infection. However, these risks are generally low, and the procedure is considered safe when performed by a skilled gastroenterologist.
