title: Bacterial Cholangitis.
abstract: The treatment of acute bacterial cholangitis requires broad-spectrum antibiotics to cover against gram-negative aerobic enteric organisms (Escherichia coli, Klebsiella species, and Enterobacter species), gram-positive Enterococcus and anaerobic bacteria (Bacteroides fragilis and Clostridium perfringens). Approximately 20% of patients with acute cholangitis fail to respond to conservative treatment with antibiotic therapy and require urgent biliary decompression, which is the mainstay of therapy. This is best accomplished by endoscopic retrograde cholangiopancreatography (ERCP) and placement of a nasobiliary drainage tube or a large bore (10 F or larger) indwelling plastic stent. Alternative therapy includes percutaneous transhepatic biliary drainage or surgical biliary decompression, but these carry a significantly higher morbidity and mortality. Supportive care includes intravenous fluid hydration to prevent renal failure and close monitoring of vital signs for determination of potential septicemia.
