Acute cholangitis with obstructive jaundice is a condition which needs biliary drainage and appropriate antibiotics. Bile culture is an optional laboratory test according to 2013, 2018 Tokyo guideline, but the clinical significance is yet unproven. And its results might indicate less information of the true pathogen regarding normal flora. Previous study conducted at our institute found drug-resistant pathogens identified in bile culture had no impact on the outcome. So the investigators are conducting a multicenter randomized controlled trial comparing groups which considers both blood and bile culture as control and which considers only blood culture as trial group in order to prove bile culture provides no additional helpful clinical information.
