Bacterial cholangitis is nearly always associated with which finding?

• A. Duct obstruction
• B. Gallbladder sludge
• C. Pancreatic duct dilation
• D. Liver abscess

Answer: (A)

Bacterial cholangitis centers on a blockage in the biliary system. When a duct is obstructed, bile cannot drain properly, leading to bile stasis and increased pressure. This environment lets enteric bacteria ascend from the intestine into the biliary tree, causing infection. Because obstruction is what enables the infection to develop, a finding of duct obstruction is the most consistent association with cholangitis. Gallbladder sludge, while related to biliary disease, isn’t the defining finding; pancreatic duct dilation points to pancreatic issues rather than cholangitis; liver abscess is a potential complication rather than a typical early association. In practice, obstruction is often accompanied by ductal dilation, and treatment focuses on relieving the obstruction plus antibiotics.
