Core Tip	Dieulafoy’s lesion inside a duodenal diverticulum is difficult to identify during quiescent phase. Conventional provocative protocols use antithrombotic agents, accompanied by delayed and unpredictable bleeding onset. This case confirms that phenylephrine provocation combined with colonoscopy enables accurate localization of occult Dieulafoy’s lesion in the distal duodenal diverticulum.
