    - Infection after endoscopic retrograde cholangiopancreatography is associated with problems in the disinfection of the scopes. Careful disinfection of the endoscopes and other endoscopic devices is mandatory to avoid an unacceptably high rate of P. aeruginosa infection.
    The most commonly isolated bacteria from blood and bile cultures after endoscopic retrograde cholangiopancreatography are Pseudomonas aeruginosa and Escherichia coli. P. aeruginosa is observed mainly in patients referred from other centers after previous diagnostic ERCP, and is unusual in patients without previous ERCP. Septicemia after ERCP is related to incomplete bile duct drainage, and in some cases, to bilio-pancreatic infected collections. The incidence of septicemia is significantly higher in cases of malignant obstruction than in benign obstruction due mainly to the problems of drainage associated with tumoral infiltration
