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.
