BACKGROUND: Gastric pneumatosis (GP) is a rare radiologic finding with an unpredictable prognosis. The aim of this study was to identify mortality risk factors from patients presenting with GP on computed tomography (CT), and to develop a model which would allow us to predict which patients would benefit most from operative management.
METHODS: Between 2010 and 2020, all CT-scan reports in four tertiary centers were searched for the following terms: "gastric pneumatosis," "intramural gastric air" or "emphysematous gastritis." The retrieved CT scans were reviewed by a senior surgeon and a senior radiologist. Relevant clinical and laboratory data for these patients were extracted from the institutions' medical records.
RESULTS: Among 58 patients with GP, portal venous gas and bowel ischemia were present on CT scan in 52 (90%) and 17 patients (29%), respectively. The 30-day mortality rate was 31%. Univariate analysis identified the following variables as predictive of mortality at the time of the diagnosis of GP: abdominal guarding, hemodynamic instability, arterial lactate level >2 mmol/l, and the absence of gastric dilatation. Multivariable analysis identified the following variables as independent predictors of mortality: arterial lactate level (OR: 1.39, 95% CI: 1.07-1.79) and the absence of gastric dilatation (OR: 0.07, 95% CI: 0.01-0.79). None of the patients presenting with a baseline lactate rate<2 mmol/l died within 30 days following diagnosis, and no more than 17 patients out of 58 had bowel ischemia (29%).
CONCLUSIONS: GP could be managed non-operatively, even in the presence of portal venous gas. However, patients with arterial lactate level>2 mmol/l, or the absence of gastric dilation should be surgically explored due to a non-negligible risk of mortality.
