Bleeding rates in patients on blood thinners undergoing endoscopy
Bleeding Rate After EGD and Colonoscopy in Patients Who Continue to Take Antithrombotic Agents
This study looks at how often patients on blood thinners bleed during endoscopy procedures like EGD and colonoscopy to see if it's safe for them to have these tests.

What this trial studies
This observational study investigates the bleeding rates associated with esophagogastroduodenoscopy (EGD) and colonoscopy in patients who continue to take antithrombotic medications. It focuses on both immediate and delayed bleeding events that may require endoscopic intervention, such as hemostatic clipping. The study aims to define the incidence of bleeding and assess the condition of submucosal arteries in excised specimens when bleeding occurs. By monitoring these outcomes, the study seeks to provide insights into the safety of performing endoscopic procedures in patients on blood thinners.
Who should consider this trial
Good fit: Ideal candidates for this study are patients who are on antithrombotic medications and are scheduled for EGD or colonoscopy.
Not a fit: Patients who undergo prophylactic clipping after biopsy or polypectomy, or those classified as American Society of Anesthesiologists physical status class IV or V, may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could help establish safer guidelines for performing endoscopic procedures in patients taking antithrombotic agents.
How similar studies have performed: While there may be studies on bleeding rates in endoscopy, this specific focus on patients continuing antithrombotic therapy is less common, making it a novel approach.
