The Usefulness and Reliability of Coagrasper for Artery Bleeding during Endoscopic Necrosectomy

Abstract

Although endoscopic necrosectomy (EN) is a less invasive therapy for walled-off necrosis (WON), arterial bleeding can occur during EN. A 60-year-old man with infected WON underwent the EN procedure. During EN, the artery in the WON cavity was injured. As the artery was directly visible, we grasped it using a Coagrasper and coagulated the bleeding point. However, the bleeding was aggravated after coagulation owing to an extension of the vessel damage. The entire vessel was grasped, and complete hemostasis was achieved. The Coagrasper is useful for managing arterial bleeding; however, it should be employed only on the basis of its characteristics and in suitable scenarios.
