The correct option is D: Deep enteroscopy. Explanation: Persistent caliber aery is called Dieulafoy's lesion. It is a large calibre aeriole that runs beneath the gut mucosa and bleeds pinpoint mucosal erosion. For management of bleeding in Dieulafoy's lesion, endoscopic therapy like thermal coagulation or band ligation is effective. In case of failure to control bleeding with above methods, angiographic embolization is used. Deep enteroscopy is used in patients with diffuse small bowel pathology like vascular ectasia.<|im_end|>
