Endoscopic mucosal resection of early oesophageal neoplasia in patients requiring anticoagulation: is it safe?

Background and aim Endoscopic mucosal resection (EMR) has become the standard treatment for early oesophageal neoplasia. The mucosal defect caused by EMR usually takes several weeks to heal. Despite guidelines on high-risk endoscopic procedures in patients on anticoagulation, evidence is lacking whether EMR is safe in such patients. We investigated the immediate and delayed bleeding risk in patients undergoing diagnostic or therapeutic oesophageal EMR comparing patients requiring warfarin anticoagulation with a control group.
