A 72-year-old man presented with melena and a drop in hemoglobin from 10 g/dL to 5 g/dL. He required three units of blood for hemodynamic stabilization. He had undergone endoscopic retrograde cholangiopancreatography (ERCP) with biliary plastic stenting 4 days previously for a periampullary tumor. On side-viewing endoscopy, a blood clot covering the tumor was found and removed, with 20 mL of 1:10 000 epinephrine injected to achieve hemostasis ([Fig. 1]).

A repeat side-viewing endoscopy on the second day showed no active bleeding. However, he bled massively after 48 hours and was sent for CT angiography which revealed ampullary mass without any demonstrable source of bleeding. An endoscopic ultrasound (EUS) examination demonstrated the course of the blood vessels proceeding towards the tumor ([Fig. 2 a]; [Video 1]). An EUS-guided intervention was planned to control the periampullary bleeding, keeping in mind the normal blood supply to the ampulla. A 25-gauge EUS needle was used to puncture one of the branches of the gastroduodenal artery (GDA) closer to the second part of the duodenum and 1 mL of 99.9 % absolute alcohol was injected ([Fig. 2 b]). A further 1 mL of alcohol was injected around another branch proceeding towards the tumor in a periarterial location ([Fig. 2 c]). Following this EUS-guided alcohol injection, repeat side-viewing endoscopy showed no active bleeding.

Video 1 The video shows endoscopic ultrasound-guided management of bleeding from a periampullary tumor, including injection of alcohol in and around the arteries supplying the tumor and subsequent coiling of the gastroduodenal artery.
Quality:
Unfortunately, the patient did rebleed again on day 6, with active ooze around the ampullary growth. Emergency Whipple’s procedure was not considered given the patient’s unwillingness to undergo such surgery at that time. Therefore, EUS-guided coiling of the GDA was planned as a salvage treatment. The transducer was placed in the antrum parallel to the GDA so that its diameter could be measured to select the size of microcoil required ([Fig. 3 a]). The GDA was punctured with a 22-gauge needle under EUS guidance and two microcoils of 4 mm in size were placed ([Fig. 3 b]; [Video 1]). Repeat side-viewing endoscopy showed no active bleeding. The patient later underwent a Whipple’s procedure, which showed well-differentiated ampullary adenocarcinoma.
