A Case of Ischemic Duodenal and Jejunal Enteritis in a Patient with Chronic Splanchnic Disease / 대한내과학회지

ABSTRACT

Gastrointestinal ischemia happens by splanchnic artery stenosis, thrombus, or physiological vasoconstriction during a low-blood-stream state. However, even if arterial stenosis exists in the upper gastrointestinal tract, ischemic injury is very rare due to rich collateral circulation. The authors experienced 92-year-old female patient with vomiting, epigastric pain, and hematemesis. An electrocardiogram showed paroxysmal atrial fibrillation. The patient had diffuse and segmental mucosal edema, erythema, and hemorrhage in the second part of the duodenum on esophagogastroduodenoscopy (EGD). On abdomen computed-tomography angiography, stenosis of the celiac and superior mesenteric arteries was observed, and segmental concentric wall thickness was seen from the proximal second portion of the duodenum to the proximal jejunum. The patient was treated with PPI and fluid therapy for one week. At follow-up EGD, the mucosa had improved compared with the previous EGD examination. In conclusion, ischemic injury rarely affects the duodenum and jejunum; however, it can develop in the presence of inducing factors.
