Gastric pneumatosis in immunocompromised patients: A report of 2 cases and comprehensive literature review.

Gastric pneumatosis (GP) is a rare finding. It can be seen with both gastric emphysema (GE) and emphysematous gastritis (EG); however, both conditions present similarly and differentiating between the 2 is difficult radiographically. Moreover, the treatment is vastly different for both conditions, in which treatment for GE is focused on supportive care while treatment for EG may even involve gastrectomy. Making the distinction between GE and EG is crucial because GE has a benign clinical course, while EG carries significant mortality. Early endoscopy may be a useful tool in differentiating between the 2 conditions and to guide further management. Herein, we present a case series of 2 immunocompromised patients who presented with symptoms and radiographic evidence consistent with gastric pneumatosis. We found that early endoscopy assisted in risk stratification and helped guide our management strategy. We recommend consideration of endoscopic evaluation as part of ritualized evaluation of patients presenting with gastric pneumatosis.
