Recurrent upper gastrointestinal ulcer bleeding treated by coil embolization guided by endoscopic ultrasonography

Clinical case 1. A 45-year-old man diagnosed with locally advanced pancreatic adenocarcinoma was admitted to hospital for acute upper gastrointestinal bleeding (UGIB). Urgent gastroscopy showed a duodenal ulcer of about 15 mm and a visible vessel. The first treatment option was to inject diluted adrenaline and place two hemoclips. Despite the treatment, progressive anemia persisted.

Repeat endoscopic assessment showed the visible vessel without the previously placed hemoclips. Endoscopic ultrasonography (EUS) allowed identification at the base of the ulcer of a 2.8-mm arterial vessel originating from the gastroduodenal artery ([Fig. 1]). The vessel was embolized using a 0.018-inch Tornado coil (Cook Inc., Bloomington, Indiana, USA) through a 22-G needle (Boston Scientific Corp., Natick, Massachusetts, USA). A later check showed absence of active bleeding ([Fig. 2], [Video 1]).

Clinical case 2. A 77-year-old man diagnosed with nasopharyngeal carcinoma was admitted to hospital for UGIB. Urgent gastroscopy showed a penetrating duodenal ulcer with a large visible vessel. Due to the size of the vessel, the initial treatment option was sclerosis using diluted adrenaline without hemoclips. EUS was performed and identified a 4-mm arterial vessel ([Fig. 3]) which was treated with injection of n-butyl-2-cyanoacrylate (Histoacryl; B. Braun, Melsungen, Germany), with a good result.

Despite the treatment, however, anemia persisted, so an endoscopic reevaluation was requested. Repeat EUS verified persistence of flow in the vessel. The vessel was embolized using a 0.018-inch Tornado coil (Cook Inc.) through a 22-G needle (Boston Scientific Corp.). A later check showed absence of flow ([Fig. 4]).

The most common type of acute UGIB is “nonvariceal.” Peptic ulcers account for 28 % – 59 % of the total. The first treatment option is dual therapy with adrenaline and mechanical or thermal methods [1]. If this treatment fails, interventional radiology with arterial embolization is the treatment of choice before surgery [2].

Endoscopic coiling has been widely used to embolize fundal or subcardial varices [3] [4]. However, there has been no previous experience in the treatment of UGIB secondary to peptic ulcers. Although comparative studies are needed, EUS-guided coil embolization can be an effective treatment option when standard treatment fails.
