What role does dilation play in flexible endoscopy?

Dilation during flexible endoscopy is a crucial technique that specifically addresses obstructions or narrowing in various passages of the gastrointestinal tract. By mechanically widening an area that is constricted, dilation helps to restore normal function and improve the passage of fluids and solids, which can be vital for patient comfort and health.

This procedure is commonly performed in cases such as strictures or stenoses that may be caused by a variety of factors, including inflammation, scarring, or tumors. The dilation can be achieved through various methods, such as balloon dilation or the use of bougies, depending on the specific clinical situation and the anatomy involved.

The effectiveness of dilation in alleviating blockage makes it a significant aspect of therapeutic endoscopy and enhances the overall management of the patient by preventing complications associated with prolonged obstruction, such as pain, vomiting, or infections.
