“…Regional ischemia due to devascularization is exaggerated by elevated intraluminal gastric pressure due to gastric stasis produced by denervation. 17 These conditions resemble those arising in our two patients who underwent lesser curvature dissection with preservation of the gastric wall.…”

Gastric pneumatosis, the presence of air within the stomach wall, is a very rare occurrence with poor outcomes. One of the most common mechanisms for gastric pneumatosis is gastric ischaemia, also a rare entity. Although patients with gastric ischaemia may require surgical intervention, they can often be treated with conservative measures such as a proton pump inhibitor, broad-spectrum antibiotics, nasogastric tube decompression, fluid resuscitation and total parenteral nutrition. We report a rare case of gastric ischaemia and pneumatosis following therapeutic left gastric artery argon plasma coagulation that was treated with conservative measures.

BACKGROUND Ischemic gastritis is a clinically rare and highly fatal disease that occurs when the hemodynamics of a patient with vascular risk is disrupted. Early diagnosis and treatment are possible only with upper endoscopy after symptom appearance. We report seven cases of ischemic gastritis and its clinical features, prognosis, and indicators that may help in early detection. CASE SUMMARY Of the seven patients, six had vascular risk and five died within 2 wk of diagnosis. Their symptoms included hematemesis and hypotension. Although surgery is a choice for radical treatment, not all patients were tolerant. For such patients, conservative treatment was selected, but all of them died. In contrast, patients who underwent repeat endoscopy showed improved mucosal findings, suggesting that this improvement may not affect prognosis. Some ischemic changes such as wall thickening, mural emphysema, and fluid retention in the stomach were observed before diagnosis through endoscopy and computed tomography (CT). The CT scan can be effective for early detection, and improvement in circulatory failure and aggressive treatment may save the lives of patients with this disease. CONCLUSION The characteristic CT findings enable early detection of ischemic gastritis. Early diagnosis increases the chance of survival if early therapeutic intervention and improvement of circulatory dynamics can be achieved in this highly fatal disease.
