An Unusual Case of Gastric Outlet Obstruction After Embolization of Gastroduodenal Artery Pseudoaneurysm

Abstract


Gastric outlet obstruction can occur secondary to intrinsic or extrinsic pathology. Historically peptic ulcer disease was the most common cause of gastric outlet obstruction but now malignancy-associated disease process is more common. Gastric outlet obstruction from mucosal ischemia caused by embolization of gastroduodenal artery is unheard of. This is due to the extensive blood supply of the stomach. We present an unusual presentation of gastric outlet obstruction in a patient with recent embolization of pancreatitis-induced pseudoaneurysm of the gastroduodenal artery. The diagnosis was confirmed with esophagogastroduodenoscopy, computed tomography, and upper gastrointestinal series. The case was managed conservatively with a clear liquid diet and proton pump inhibitors. Repeat upper endoscopies at 1 and 6 months after presentation confirmed disease resolution. No guidelines exist on the management of such cases due to the rarity of the disease.
