Endoscopic visible light spectroscopy: a new, minimally invasive technique to diagnose chronic GI ischemia

The diagnosis of chronic GI ischemia (CGI) remains a clinical challenge. Currently, there is no single simple test with high sensitivity available. Visible light spectroscopy (VLS) is a new technique that noninvasively measures mucosal oxygen saturation during endoscopy.To determine the diagnostic accuracy of VLS for the detection of ischemia in a large cohort of patients.Prospective study, with adherence to the Standards for Reporting of...
