NCT07007598

Brief Summary

This observational study aims to retrospectively determine if clips can prevent post-polypectomy bleeding in adults who have received restarted anticoagulants after a colorectal polypectomy, using a large, single-center patient registry. The main question it aims to answer is: Can clips prevent post-polypectomy bleeding in adults who have received restarted anticoagulants after a colorectal polypectomy? Researchers will compare adults who received preventive clipping after a polypectomy with those who did not, regarding colorectal bleeding after receiving restarted anticoagulants. Participants have undergone a colorectal polypectomy and received restarted anticoagulants (acetylsalicylic acid excluded) after the procedure.

Outcome Measures

Primary Outcomes (1)

  • Colorectal Post-polypectomy bleeding

    Mucosal defect-associated bleeding after removal of a colorectal polyp bei endoscopic polypectomy. The metachronous interval bleeding rate is calculated by dividing the number of bleeding events by the number of colonoscopies with polypectomy. The following are counted as polypectomy bleeding: 1. Polypectomy bleeding is visualized directly during a subsequent colonoscopy. 2. Polypectomy bleeding is considered probable if a subsequent colonoscopy is performed due to lower gastrointestinal bleeding, and evidence of blood is found in association with the polypectomy. 3. Polypectomy bleeding is considered probable if the patient was hospitalized for monitoring or had his hospital stay extended because he showed visible perianal bleeding. However, a colonoscopy was not performed because the bleeding had stopped spontaneously and/or the risk of a subsequent colonoscopy was deemed too high in relation to the potential benefits.

    Up to 30 days after colorectal endoscopic polypectomy

Study Arms (2)

Colorectal polypectomy and prophylactic clipping before restarted anticoagulants

At least one prophylactic clip is applied to close the mucosal defect after polypectomy

Device: Hemostatic clip

Colorectal polypectomy without prophylactic clipping before restarted anticoagulant

A prophylactic clip is not applied to close the mucosal defect after polypectomy.

Interventions

The hemostatic clip is endoscopically applied after a colorectal polypectomy to close the mucosal defect.
