Critically ill patients are at increased risk of developing stress-related mucosal lesions. The pathogenesis of stress-related mucosal disease is not entirely clear, but probably is associated with impairment of mucosal protective mechanisms due to compromised gastric mucosal microcirculation. Acid also plays an integral role. The incidence of gastrointestinal bleeding among ...

OBJECTIVES: Endoscopic screening of cirrhotics for large esophageal varices (EV) is advocated before initiation of prophylactic therapy for variceal bleeding. Conscious sedation for conventional endoscopy is problematic in cirrhotic patients because of risk of prolonged encephalopathy. Unsedated transnasal endoscopy (T-EGD) is a new technique, which allows for unsedated examination because ...

Data suggest that cyclooxygenase (COX)-2 inhibitors are safer for the gastrointestinal tract than traditional nonsteroidal antiinflammatory drugs (NSAIDs). Rofecoxib, a COX-2-specific NSAID, does not inhibit the COX-1 enzyme, thereby decreasing the potential for gastrointestinal-related adverse effects. Patients who are at an increased risk for NSAID-related gastrointestinal bleeding are therefore appropriate ...
