Older age, longer procedures and tandem endoscopic-ultrasound as risk factors for post-endoscopic retrograde cholangiopancreatography bacteremia

Figure 1 Study flow chart. PEB: Post endoscopic retrograde cholangiopancreatography bacteremia; ERCP: Endoscopic retrograde cholangiopancreatography.

Figure 2 Bacterial type's dispersion among entire cohort and according to the days past endoscopic retrograde cholan-giopancreatography date. A: Bacterial type's dispersion among entire cohort; B: Bacterial type's according to the days past endoscopic retrograde cholangiopancreatography date. ERCP: Endoscopic retrograde cholangiopancreatography; ESBL: Extended spectrum beta-lactamase.
