外傷後肝外胆管狭窄の2例にexpandable metallic stents (EMS)を使用し良好な結果を得たので報告する.経乳頭的ステント留置術を1例,経皮経肝的ステント留置術を1例に施行したところ,2例とも胆管炎,閉塞性黄疸は治癒した.両方法とも低侵襲で安全に施行でき,外傷後胆管狭窄など良性の胆管狭窄に対する有効な治療手段と考えられた.We had good results from using expandable metallic stents (EMS) in two patients with posttraumatic extrahepatic biliary duct strictures. A transpapillary biliary stenting (TBS) was performed on one patient, and a percutaneous transhepatic biliary stenting (PTBS) was performed on the other patient. In both cases, cholangitis and obstructive jaundice were cured. Both methods of stenting were performed safely with low invasion. Therefore, EMS is an effective treatment means for benign biliary duct strictures including posttraumatic biliary duct strictures
