Detective flow imaging endoscopic ultrasonography for diagnosing subepithelial lesions

Diagnosis of Gastrointestinal Subepithelial Lesions Using a Novel Endoscopic Ultrasonography Imaging Technique

Not applicable Interventional Instituto Ecuatoriano de Enfermedades Digestivas · NCT05474794

This study is testing a new imaging technique to see if it can better identify certain types of growths in the digestive system, helping doctors tell the difference between cancerous and non-cancerous tumors.

What this trial studies

This clinical trial evaluates a novel diagnostic method called detective flow imaging endoscopic ultrasonography (DFI-EUS) for the assessment of subepithelial lesions (SELs) in the gastrointestinal tract, particularly focusing on differentiating gastrointestinal stromal tumors (GISTs) from benign leiomyomas. The study aims to improve diagnostic accuracy by utilizing DFI-EUS, which is designed to detect slow and fine blood flow in these lesions without the risks associated with contrast agents. Patients referred for endoscopic ultrasound (EUS) will be included, and the effectiveness of DFI-EUS will be compared to traditional contrast-enhanced EUS (CE-EUS).

Who should consider this trial

Good fit: Ideal candidates for this study are patients referred for endoscopic ultrasound evaluation of subepithelial lesions.

Not a fit: Patients with contraindications for contrast agent administration or those with clinical conditions that make EUS inviable will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more accurate diagnoses of GISTs, allowing for better treatment decisions and improved patient outcomes.

How similar studies have performed: While traditional EUS techniques have been utilized, the DFI-EUS approach is novel and has not been extensively tested in previous studies.
