Recurrent Pyogenic Cholangitis

**Semantic type:** Disease or Syndrome

**Definition:** A recurrent form of cholangitis that is characterized by intrabiliary pigment stone formation, biliary tree stricture and obstruction, and recurrent bouts of cholangitis. There is an association with biliary parasitosis, but evidence supporting these infections in the pathogenesis of recurrent pyogenic cholangitis is inconclusive. The most common causes of death are sepsis, liver failure, or complications from cirrhosis. Patients are also at increased risk of cholangiocarcinoma.

**Synonyms:** - Cholangiohepatitis - RPC
