Abstract
Percutaneous Y-shape reconstructive biliary stenting in the Klatskin tumor is typically performed through bilateral biliary access. Single access from a right-side biliary entry is the more commonly used side for biliary access in general. We present a successful Y-shaped biliary stent reconstruction through a single left-side biliary approach. Unilateral single access Y-shaped biliary stenting can be technically challenging; when performed through a left biliary approach, an additional technical challenge may arise due to the unusual combination of Y-shaped biliary stent reconstruction and the single left-side biliary approach. We concluded that percutaneous Y-shaped biliary reconstruction through a left-sided unilateral approach is a technically feasible, less invasive interventional approach in managing Klatskin tumor.
