OR Discussion of Procedures by Variant Variant 1: Adult. Suspected nonvariceal upper gastrointestinal bleeding; no endoscopy performed. Initial imaging. Endoscopy is the usual first test in patients presenting with overt or occult UGIB [6]. This variant is applicable to a clinical scenario in which a patient presents clinically with overt UGIB and initial endoscopy was not performed due to large volume bleeding or clinical instability.
