Overview
Emphysematous gastritis (EG) is a severe condition characterized by gas-producing organisms invading the gastric wall, often associated with high mortality rates, though recent trends show improved survival 1.Diagnosis
Clinical presentation includes severe abdominal pain, nausea, vomiting, and signs of systemic toxicity 1.
Endoscopy (EGD) is crucial for visualizing gas bubbles within the gastric wall 1.
Imaging studies, such as CT scans, can reveal characteristic gas collections within the stomach 1.
Laboratory tests often show leukocytosis and electrolyte imbalances 1.Management
First-line treatment: Broad-spectrum antibiotics targeting anaerobic organisms, such as metronidazole and piperacillin-tazobactam 1.
Adjunctive management: Surgical intervention may be necessary in cases of perforation, obstruction, or failure of medical management 1.
Supportive care: Fluid resuscitation, electrolyte correction, and management of complications like shock 1.Special Populations
Elderly: Higher mortality rates observed, likely due to comorbidities and frailty 1.
Comorbidities: Presence of diabetes and alcohol abuse significantly impacts outcomes and may necessitate tailored antibiotic choices 1.Key Recommendations
Utilize endoscopy (EGD) for definitive diagnosis of emphysematous gastritis 1.
Implement broad-spectrum antibiotic therapy targeting anaerobes early in management 1 (Evidence: Moderate).
Monitor length of stay as a critical predictor of mortality; shorter stays may correlate with better outcomes 1 (Evidence: Moderate).References
