Abstract
In performing endoscopic treatment in patients treated with antiplatelets or anticoagulants, the administration is suspended to prevent intraoperative and postoperative bleeding. However, suspension of the administration naturally increases the risk of thromboembolism, which may lead to serious complications. Therefore, in consideration of these two opposing risks, the Endoscopy Department established provisional rules concerning the administration of anti-platelets and anticoagulants during endoscopic treatment by obtaining cooperation from related departments in the hospital. Although these rules were determined without clear evidence in Japan, they are considered to be meaningful in that they were established through consultation with related departments.
