INTRODUCTION
C. sinensis infection is frequently reported in East Asian countries, including China, Korea, Japan, and Vietnam. Clonorchiasis is most often caused by transmission of the adult flukes of C. sinensis to humans from freshwater fish[1], which subsequently parasitize the biliary system[2].C. sinensis infection is often complicated clinically by acute cholangitis. Some studies have reported that clonorchiasis is related to hepatobiliary morbidity[3,4,5] and cholangiocarcinoma[6,7]. The clinical symptoms of clonorchiasis have no obvious specificity, and can easily lead to missed diagnosis and misdiagnosis.
A case of choledocholithiasis comorbid with C. sinensis was admitted to Cheng Fei Hospital in Sichuan in May 2021, and is reported here.
