Microbiology of bile in extrahepatic biliary obstruction: A tropical experience.

Purpose: Bile is considered sterile, but in obstructed biliary system, growth of micro-organisms results in bacteraemia and toxaemia. We analysed bacterial profile of patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) and evaluated antibiotic resistance patterns to formulate strategy for antibiotics in patients undergoing ERCP.

Materials And Methods: Patients with cholestasis who underwent ERCP were enrolled.
