Management of a Dieulafoy ulcer bleed with an over-the-scope clip

Post written by Malay Sharma, MD, DM, from the Jaswant Rai Speciality Hospital.

This video shows the EUS features of Dieulafoy ulcer and its possible role in diagnosis of obscure overt GI bleeding. The OTSC can play an important role in the treatment of Dieulafoy ulcer.

A 50-year-old man presented with massive hematemesis. Upper-Gastrointestinal (GI) endoscopy revealed a visible vessel in the center of a small ulcer over a small submucosal bulge in the anterior wall of the first part of duodenum. EUS color Doppler showed a vessel entering the submucosa with arterial signals and confirmed the diagnosis of Dieulafoy ulcer. Endoscopic clips and adrenaline injection failed to control the bleeding. Complete hemostasis was then achieved with an over the scope clip (OTSC).

Dieulafoy ulcer should be considered in differential diagnosis of small ulcer with submucosal bulge presenting with massive GI bleed. EUS has a diagnostic role in obscure upper GI bleed and can diagnose vascular anomalies which can be missed on normal endoscopy. OTSC is useful in treatment of Dieulafoy ulcer.

GI bleeding is a common condition. Rebleeding occurs in 15% to 20% of patients. This is likely related to the failure to recognize the presence of submucosal vessels at endoscopy or the failure to deliver adequate endoscopic therapy. An endoscopic approach based on the direct imaging of submucosal arterial flow and imaging-guided intervention would clearly be preferable. The specific bleeding source sometimes fails detection with routine endoscopic techniques, which suggests a potential role for EUS that allows transmural imaging. Further role of EUS should be explored as diagnostic modality for obscure upper GI bleeding.
