What this trial studies

This clinical trial evaluates the effectiveness of PuraStat®, a hemostatic agent, in reducing the incidence of delayed bleeding following endoscopic submucosal dissection (ESD) for colorectal lesions. The study focuses on patients at high risk of bleeding, particularly those on anticoagulant or antiplatelet therapy. By comparing PuraStat® to standard treatment methods, the trial aims to determine if this new approach can improve patient outcomes and reduce complications associated with delayed bleeding. The study will also assess the side effects and overall effectiveness of both strategies.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a single colorectal lesion requiring ESD and who are on anticoagulant or antiplatelet therapy.

Not a fit: Patients with severe fibrosis, a history of familial colorectal polyposis, or those who may have an allergic reaction to PuraStat® may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the risk of delayed bleeding in patients undergoing colorectal surgery, improving recovery and outcomes.

How similar studies have performed: Previous studies have indicated that hemostatic agents like PuraStat® can reduce bleeding rates, suggesting potential success for this approach.
