The use of endoscopic retrograde cholangiopancreatography for treating benign biliary strictures has become the standard of practice, with surgery and percutaneous therapy reserved for selected patients. The gold-standard endoscopic therapy is dilation of the stricture followed by placing and exchanging progressively larger and more numerable plastic stents over a 1-year period. Newer modalities, including the use of fully covered metal stents, are currently under investigation in an effort to improve the treatment of benign biliary strictures.
内镜逆行胰胆管造影术用于治疗良性胆管狭窄已成为标准治疗方法，手术和经皮治疗则用于特定患者。金标准的内镜治疗是扩张狭窄部位，然后在1年时间内逐步放置和更换更大数量的塑料支架。包括使用全覆膜金属支架在内的更新的治疗方式目前正在研究中，以努力改善良性胆管狭窄的治疗。
