Frequency of Biliary Infection and Antimicrobial Susceptibility Pattern in Patients with Extra-Hepatic Biliary Obstruction Undergoing Non-Surgical Interventions with Reused Accessories

Bile is normally sterile. Bactibilia occurs when bile flow is impaired and bacteria gain access to the biliary duct by the papilla or portal circulation. Bile duct obstruction leads sequentially to increase in intra biliary pressure, infection of bile, cholangiovenous and cholangiolymphatic reflux leading to bacteremia [1-3]. The bacteria described commonly in biliary tract infections include Escherichia coli, Klebsiella and Enterococci [4-6]. Cholangitis is usually more common when the biliary obstruction is partial and intermittent, as often seen with stones in the common bile duct. Acute obstructive suppurative cholangitis a severe and fulminant form of biliary tract infections may occur when pathogenic bacteria gain access to a completely obstructed biliary system.
