Comparing two methods for diagnosing esophageal varices in biliary atresia patients

Difference in Aerosol-generating Amount Between Wired Magnetic-assisted Capsule Endoscopy System and Esophagogastroduodenoscopy Examination of Varices in Biliary Atresia Patients

Not applicable Interventional National Taiwan University Hospital · NCT06017102

This study is testing if a new method using a magnetically assisted capsule can safely and effectively diagnose esophageal varices in patients with biliary atresia, compared to the traditional endoscopy.

What this trial studies

This clinical trial aims to evaluate the safety and effectiveness of wired magnetically assisted capsule endoscopy (MACE) compared to traditional esophagogastroduodenoscopy (EGD) for diagnosing esophageal varices in patients with biliary atresia. Participants will undergo either MACE or EGD, with a focus on assessing diagnostic accuracy and the potential reduction of droplet generation during the procedure. The study seeks to determine if MACE can provide a less invasive alternative for these patients.

Who should consider this trial

Good fit: Ideal candidates for this study are biliary atresia patients over 6 years old who are stable and do not have acute gastrointestinal bleeding.

Not a fit: Patients with metal implants, electronic devices, or those experiencing acute upper gastrointestinal bleeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer a safer and more comfortable diagnostic option for patients with biliary atresia and esophageal varices.

How similar studies have performed: While traditional methods have been widely used, the approach of using wired magnetically assisted capsule endoscopy is relatively novel and has not been extensively tested in this specific context.
