Background: The ingestion of caustic substances induces an extensive spectrum of injuries to the aerodigestive tract which include extensive necrosis and perforation of the esophagus and stomach. The gold standard of safely assessing depth, extent of injury, and appropriate therapeutic regimen is esophagogastroduodenoscopy (EGD). The objective of this study was to report our clinical experience and to evaluate the role of a 6-point EGD classification system of injury in predicting outcomes in adult patients diagnosed with caustic agent ingestion.

Both SOFA and RIFLE category showed high discriminative power in predicting hospital mortality in critically ill patients with cirrhosis. The RIFLE classification is a simple and easily applied evaluative tool with good prognostic abilities.

This investigation confirms that the prognosis for cirrhotic patients admitted to ICU is grave. The OSF score is a simple, reproducible, and easily applied tool with excellent prognostic abilities that can provide objective information for patients' families and physicians and supplement the clinical judgment of prognosis.
