1Choledochal cysts: Similarities and differences between Asian and Western countries显示文摘Choledochal cysts(CCs)are rare bile duct dilatations,intra-and/or extrahepatic,and have higher prevalence in the Asian population compared to Western populations.Most of the current literature on CC disease originates from Asia where these entities are most prevalent.They are thought to arise from an anomalous pancreaticobiliary junction,which are congenital anomalies between pancreatic and bile ducts.Some similarities in presentation between Eastern and Western patients exist such as female predominance,however,contemporary studies suggest that Asian patients may be more symptomatic on presentation.Even though CC disease presents with an increased malignant risk reported to be more than 10%after the second decade of life in Asian patients,this risk may be overstated in Western populations.Despite this difference in cancer risk,management guidelines for all patients with CC are based predominantly on observations reported from Asia where it is recommended that all CCs should be excised out of concern for the presence or development of biliary tract cancer.George N Baison Morgan M Bonds William S Helton Richard A Kozarek 2019World Journal of Gastroenterology2019,25,26:16
