Discussion:
Many patient’s who present with ascending cholangitis present without classic signs and symptoms.  Classically, patients would present with RUQ pain, fever and jaundice. However, some recent studies have shown that these symptoms may only be present 15-20% of the time. The key symptom is fever, which is present in 90% of patient’s.  Factors that play a role in the pathogenesis of the disease involve an obstruction or an increase in luminal pressure that leads to a bacterial infection.  Risk factors include stones, recent cholecystectomy, ERCP, history of cholangitis, or HIV.  Bacteria are thought to invade the obstructed biliary tree in a retrograde fashion.  The most common bacteria involved are E coli, klebsiella, enterococcus, and bacteroides.  Work-up will show elevated WBC in 79% of patients, with LFT’s indicating cholestasis, with hyperbilirubinemia and an increased alkaline phosphatase level.  The most common sign on ultrasound will be a dilated common bile duct which is only present 64% of the time.  If there is a high clinical suspicion the patient can be taken for ERCP for both diagnosis and therapy.  Empiric anti-microbial therapy should be aimed at treating gram negative, gram positive and anaerobic bacteria. Drainage and decompression are required, with a mortality rate approaching 100% if this is delayed 72 hours.
