Using low-energy argon plasma to treat duodenal polyps in patients with Familial Adenomatous Polyposis

Cold Atmospheric Plasma for the Endoscopic Treatment of Duodenal Polyps in Patients With Familial Adenomatous Polyposis

Not applicable Interventional Universitätsklinikum Hamburg-Eppendorf · NCT06435533

This study is testing a new way to treat precancerous duodenal polyps in people with Familial Adenomatous Polyposis using low-energy argon plasma to see if it can safely help manage these polyps.

What this trial studies

This study investigates the feasibility of using low-thermal argon plasma coagulation to treat precancerous duodenal polyps in patients with Familial Adenomatous Polyposis (FAP). FAP is a genetic disorder that leads to the formation of numerous colorectal polyps, increasing the risk of cancer. The study aims to apply a new argon plasma coagulation technique during routine endoscopic surveillance to effectively manage these polyps while minimizing thermal damage to the delicate duodenal wall. Participants will undergo treatment with a specific argon plasma device designed for this purpose.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with confirmed Familial Adenomatous Polyposis and duodenal polyposis who require follow-up endoscopy.

Not a fit: Patients with high-grade dysplasia, carcinoma, or other severe health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a safer and more effective method for managing duodenal polyps in FAP patients, potentially reducing their cancer risk.

How similar studies have performed: While the use of argon plasma coagulation has been successful in other medical fields, this specific application for duodenal polyps in FAP patients is novel.
