Patients and Methods: Cirrhotic patients who underwent elective endoscopic cyanoacrylate injection for gastric variceal obliteration were included as our target group (n=18), whereas cirrhotic patients who underwent routine endoscopic surveillance were recruited as a control group. (n=17). Blood cultures were taken from all patients at 0 minute (before procedure), 5 minutes and 3 hours after endoscopy. The tip of injected needle was also cultured in the cyanoacrylate group.
