Endoscopic dilation

Certain conditions can lead to a narrowing (stricture) of the digestive tract: scarring after inflammation or surgery, inflammatory diseases, motility disorders of the esophagus such as achalasia. These strictures hinder the passage of food or bowel function and can be treated by endoscopic dilation, without an incision. The procedure consists of gradually widening the narrowed area using inflatable balloons or bougies of increasing caliber, introduced under direct vision through the endoscope. Several sessions spaced over time are sometimes needed to achieve a stable, lasting result. At Clinique Pasteur Tunis, endoscopic dilations are performed under sedation or anesthesia, on a day-case basis in most instances, by experienced endoscopists. The patient is monitored after the procedure and goes home with simple dietary instructions.
