Foreign bodies as a nucleus for precipitation of gall-stones are not frequently observed. The combination of primary immigrated foreign bodies into the bile ducts and following encasing by a gall-stone could be even more rarely found. A case report is presented concerning a patient, in whom a hemo-clip was fixed away from the bile-ducts in connection with a cholecystectomy and revision of the common bile-duct. After hospital admission because jaundice in the PTC was found a prepapillary concrement with a central hemo-clip, which has served as a nucleus for precipitation after transmural immigration.
异物作为胆结石形成的核心并不常见。原发性移入胆管的异物随后被胆结石包裹的情况则更为罕见。本文报告一例患者，在胆囊切除术和胆总管修复术中，一个血管夹被固定在远离胆管的位置。患者因黄疸入院后，经经皮肝穿刺胆管造影（PTC）发现一个乳头前结石，结石中心有一个血管夹，该血管夹经穿壁迁移后成为结石形成的核心。
