Frequency of XXXX after linear EUS of the upper GI tract with and without FNA.

@entity1 @entity281 @entity418 @entity2259 @entity884
BACKGROUND: Few data are available concerning the frequency of @entity2259 after diagnostic EUS or EUS-guided FNA. This study was undertaken to provide these data and to determine whether present guidelines for prophylactic administration of antibiotics to prevent @entity884 during upper endoscopy are applicable to EUS and EUS-guided FNA. METHODS: A total of 100 @entity1 who were to undergo diagnostic EUS of the upper-GI tract and 50 who were to have upper-GI EUS-guided FNA were enrolled in this prospective study. Blood cultures were obtained before and within 5 minutes after the conclusion of the procedure. In case of bacterial growth, @entity1 were observed for at least 3 days for signs of @entity281 . RESULTS: After diagnostic EUS, significant @entity2259 was found in two @entity1 with @entity418 (2%: 95% CI[0%, 4.8%]) and after EUS-guided FNA in two @entity1 (4%: 95% CI[0%, 9.6%]). The difference was not statistically significant. None of these @entity1 developed clinical signs of @entity281 . Risk factors predisposing to @entity2259 could not be identified. CONCLUSION: The frequency of @entity2259 after EUS, with and without FNA, is within the range of that for diagnostic upper endoscopy. Therefore, the same recommendations for prophylactic administration of antibiotics to prevent @entity884 may be applied in @entity1 undergoing EUS and EUS-guided FNA. The role of @entity418 as a predisposing factor to EUS-associated @entity281 remains uncertain.
