AbstractWe herein report two cases of hemorrhagic ampullary lesions in which endoscopic papillotomy was performed to control bleeding and resulted in successful treatment. Both patients were pathologically diagnosed with an underlying pathology characterized by inflammatory cell infiltration and capillary proliferation. They also had disposing factors for bleeding, such as antithrombotic therapy and idiopathic thrombocytopenic purpura. Endoscopic treatment was selected because the risk of surgical resection was high due to the patients' hemorrhagic condition. Both patients were successfully treated without any serious adverse events and had an uneventful postoperative course with no relapse of bleeding.
