Emphysematous gastritis (or phlegmonous gastritis) and gastric emphysema (or gastric pneumatosis) are variations of conditions associated with the presence of intramural air in the stomach. The presence of air in the gastric wall is a very rare clinical condition, associated with bacterial infection, increased intragastric pressure from gastric outlet obstruction, gastric mucosal disruption or air dissection from the mediastinum. In adults, this can occur in the setting of instrumentation-related injury, gastric outlet obstruction by gastric, duodenal or pancreatic malignancies or bowel ischemia. Here we describe a case of gastric emphysema related to repeated biliary stenting and partial duodenal obstruction in a patient with inoperable periampullary cancer, and provide the first description of the endoscopic ultrasonographic findings of gastric emphysema in the literature. In our case, endoscopic ultrasound showed a band of bright echogenicity arising from the submucosa layer, representing air in the gastric wall.

Emphysematous gastritis is a rare form of gastritis characterized by gaseous dissection of the stomach wall usually secondary to invasion by gas forming organisms, corrosive ingestion, trauma, or gastric infarction. We report a unique case of emphysematous gastritis secondary to ulcerative esophagitis without an underlying history of trauma, ischemia, or ingestion of corrosive agents. The patient responded well to conservative management. Emphysematous gastritis is a deadly infectious disease. Early recognition and management are crucial as there is no specific approach to treatment despite advances in medical science.

Introduction. Gastric emphysema can present both a diagnostic challenge and a life-threatening condition for patients and has only once been reported as being recurrent. Background. A 64-year-old male presented with chronic abdominal pain and was found to have gastric pneumatosis on CT scan. The patient was successfully managed conservatively. The cause was attributed to aberrant arterial anatomy and atherosclerosis along with hypotension. The patient has since had 3 episodes of recurrent gastric emphysema, all managed nonoperatively. Discussion. To our knowledge, this is the first case of both serial episodes of gastric pneumatosis and gastric mucosal ischemia as a precipitating factor for the development of gastric emphysema.

Emphysematous gastritis is a rare infection of the gastric wall with 55%-60% mortality. A 44-year-old man with AIDS, hepatitis C, and intravenous drug use presented with a 1-day history of acute-onset abdominal pain, nausea, and nonbloody, nonbilious emesis. On examination, he was afebrile without other vital sign abnormalities. He had epigastric abdominal tenderness without rebound or guarding. The peripheral-blood leukocyte count was elevated to 12.8 with 93.8% neutrophils. The patient's clinical presentation markedly improved with IV fluids and broad-spectrum antibiotic therapy. His presentation and radiologic findings, including gastric intramural air and air in the portal vein, are consistent with emphysematous gastritis. Conservative management is first-line for milder cases of emphysematous gastritis. Exploratory laparotomy and total gastrectomy are indicated only in severe cases such as transmural ischemia and peritonitis. Immune-compromised status is a predisposing factor and associated with subtler findings than the classic dramatic clinical presentation.

Gastric emphysema or air in the stomach wall is a rare condition resulting from the disruption of gastric mucosa and entry of air into the stomach wall which could be from severe vomiting, instrumentation or endoscopy, gastric ischemia, and dissection of air from the mediastinum. Treatment is usually conservative and supportive. We report the case of a 70-year-old woman with a three-day history of nausea and vomiting who presented with gastric emphysema on computed tomography (CT) imaging; she responded very well with conservative treatment and was discharged in a stable condition.
