The worms were identified as Clonorchis sinensis (also called Opisthorchis sinensis). The patient was given praziquantel and had a quick and uneventful recovery. The clinical manifestations of clonorchiasis tend to reflect the worm burden and the duration of infection. Clonorchis may persist in the biliary tree for decades, and prolonged infestation is associated with the development of cholangiocarcinoma. Acute cholangitis and pancreatitis are rare but important complications of C. sinensis infestation.
