Core tip: Choledochal cysts (CCs) are rare, predominantly occurring in Asian populations. While current global guidelines for their management are based on studies on Asian populations, there may be relevant differences between Western and Asian populations. For example, the risk of malignancy in Western populations may be lower than that reported in Asian populations. Although studies on CC disease in Western populations have been conducted, further evidence is still needed to properly elucidate this disease in the West and design appropriate clinical guidelines. Continued efforts in this regard are paramount, especially with the evolving field of hepatobiliary surgery that has recently seen the adoption of minimally invasive techniques.
