The rare finding of a Dieulafoy’s lesion at the major papilla

 

 Permissions and Reprints

A 58-year-old man with history of diabetes, hypertension, chronic kidney disease, and chronic calcific pancreatitis presented with five episodes of coffee-ground emesis and melena. The patient had previously required endoscopic transmural drainage of walled-off pancreatic necrosis 1 year earlier with a lumen-apposing metal stent, which had since been removed.

The patient presented with tachycardia with a heart rate of 125 beats/minute and blood pressure was 107/75 mmHg. Laboratory examination revealed hemoglobin of 6.8 g/dL (baseline level of 13 g/dL). Upper endoscopy with a forward-viewing gastroscope with a distal attachment cap revealed blood in the second part of the duodenum as well as a clot in the area of the major papilla ([Fig. 1]). Due to concern for hemosuccus pancreaticus from a bleeding pseudoaneurysm, a computed tomography angiogram was performed, which did not demonstrate a pseudoaneurysm or any active bleeding. Subsequent examination with a duodenoscope revealed a pulsatile vessel ([Fig. 2], [Video 1]) in the absence of an ulcer, confirming the diagnosis of a Dieulafoy’s lesion at the major papilla, which was clearly separate from the bile duct and pancreatic duct orifices.

Endoscopic therapy with epinephrine injection and bipolar cautery was successful in treating the lesion ([Fig. 3]).

Defined as dilated aberrant submucosal vessels eroding through overlying epithelium without ulceration, Dieulafoy’s lesions can present anywhere along the gastrointestinal tract [1]. Typically located in the proximal stomach, Dieulafoy’s lesions are exceedingly rare at the major papilla with few reported cases at this location [2]. Risk factors for the development of Dieulafoy’s lesions include male sex, hypertension, chronic kidney disease, and diabetes, all of which were noted in this patient [1]. Additional differential diagnoses in this patient would include hemosuccus pancreaticus from a pseudoaneurysm or gastric varices secondary to splenic vein thrombosis [3].
