Acute cholangitis is a systemic infectious disease characterized by acute inflammation and infection in the bile ducts. Other terms (eg, suppurative cholangitis or ascending cholangitis) are also used for this condition. Acute cholangitis was first described by Charcot as “hepatic fever” in 1877 [1]. As a result, the typical signs and symptoms of acute cholangitis—intermittent fever with chills, right upper quadrant pain, and jaundice—are known as Charcot’s triad.
