Counterpoint: Proximal Biliary Strictures Mimicking Hilar Cholangiocarcinoma

Abstract

The management of hilar cholangiocarcinoma remains challenging. Its incidence is increasing, diagnostic methods have limited accuracy, and surgical approaches are evolving continually. Diseases that masquerade as hilar cholangiocarcinoma confound the surgical management of this already complex clinical problem. Nahum, Smith, and Jarnagin importantly outline the benign diseases that masquerade as hilar cholangiocarcinoma and attempt to highlight their clinical and imaging features to provide clinical clues for others to avoid overtreatment of benign diseases. There are valuable lessons worth learning from their work.
