A Management Algorithm Based on Delayed Bleeding After Wide-Field Endoscopic Mucosal Resection of Large Colonic Lesions

Based on a multicenter prospective study, CSPEB resolves spontaneously in 55% of patients. We developed a risk factor-based algorithm that might assist physicians in the management of bleeding. Patients responding to initial resuscitation can be observed, with a lower threshold for intervention in those with the identified risk factors.
