Detection and characterization of colorectal polyps using high-definition white light and i-Scan: Evidence-based consensus recommendations using a modified Delphi process.

Background: i-Scan is an image enhancement modality, which provides enhanced views of mucosal structures and vascular patterns.

Methods: A modified Delphi process was used to develop a series of evidence-based statements on the role of high-definition white light (HDWL) and i-Scan for the detection and diagnosis of colorectal neoplasms. Each statement was voted to achieve consensus (i.

Over-the-Scope Clips Are More Effective Than Standard Endoscopic Therapy for Patients With Recurrent Bleeding of Peptic Ulcers.

Background & Aims: Endoscopic hemostasis is effective in treatment of bleeding peptic ulcers. However, rebleeding is difficult to treat and associated with substantial morbidity and mortality. We performed a prospective randomized trial to determine whether over-the-scope clips (OTSCs) are more effective than standard treatment of severe recurrent upper gastrointestinal bleeding.
