Brief Summary
Study design: A national, multi-center, patient-blinded, randomized clinical trial. Study population: Patients undergoing EMR with a moderate to severe risk (right sided colon, ≥2cm) of developing Delayed Bleeding (DB). Intervention: PC will be compared to standard care (no PC). Main study endpoints: Primary endpoint is the incidence of DB. Secondary endpoints are cost-effectiveness, quality of life and (severe) adverse events related to PC, adenoma recurrence and risk factors for DB.

Interventions
A hemoclip will be placed after every 0,5-1,0 cm of the resected area to proximate wound edges.
Eligibility Criteria
You may qualify if:
- laterally spreading or sessile polyp morphology (Paris classification 0-IIa/b/c) proximal to the splenic flexure, measuring 2-6 cm
- All patients aged \>18 years undergoing an EMR
- Written informed consent
You may not qualify if:
- Previous resection or attempted resection of a lesion less than 30 days ago or in the same session,
- Clip deployed prior to the completion of the EMR for a perforation or a major intra-procedural bleeding not treatable by coagulation,
- Endoscopic appearance of invasive malignancy (non-lifting Kato D, Kudo V pit pattern),
- Pregnancy,
- Active inflammatory colonic conditions (e.g. inflammatory bowel disease),
- Insufficiently corrected anticoagulants AND/OR a clotting disorder (platelet count \<50x109/l, INR \> 1,5),
- American Society of Anesthesiology (ASA) Grade IV-V,
- Macroscopic non-radical resection,
- \>1 lesion in 1 session,
- Involvement of valvula Bauhin or appendiceal orificium
