Biliary tract: microbiological analysis of bile during cholangiography.

摘要

Bacteremia as a complication of biliary intervention tends to occur in patients with obstructed bile flow, especially those who have previously undergone orthotopic liver transplantation (OLT), surgery to the biliary tree, sphincterotomy, or placement of a biliary stent. The risk of systemic infection is highest when adequate biliary drainage has not been achieved after intervention, which typically involves endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangio-graphy (PTC). The risk of bacteremia after ERCP has gradually fallen to 0.4-1.0%, as a result of strict standards of equipment sterilization, improved operator technique and avoidance of ERCP as a diagnostic procedure,
