Researchers developed a new classification for biliary strictures after liver transplantation, enhancing treatment choices and outcomes.

• Patients were classified into three types: type I (43.8%), type II (32.3%), and type III (24.0%).
• Type I patients using fully covered metal stents had fewer procedures and lower costs compared to plastic stents (p=0.02 and p=0.04).
• Stent-free success rates were highest for type I (69.0%) and lowest for type III (34.7%, p=0.03).

This classification aids surgeons in selecting the most effective treatment strategies, particularly for complex cases.
