采用改良Gianturco设计的自膨胀金属支架治疗17例胆道良性狭窄。13例患者多次手术修复不成功，4例因临床状况未行手术。所有患者均行多次经皮球囊扩张术，均未成功。支架经皮放置，经肝入路，无并发症。14例（82.4%）患者狭窄节段达到适当口径，症状稳定缓解，肝功能检查恢复正常。1例患者获得部分原发性成功；2例患者初步成功，但5个月后狭窄复发。平均随访时间为8个月。结果表明，放置这些支架可能是难治性复发的永久治疗方案。需要进一步的随访和实验研究来阐明长期通畅性和生物耐受性。
Self-expanding metallic stents of a modified Gianturco design were used to treat benign strictures of the biliary tree in 17 patients. Thirteen patients had undergone several unsuccessful surgical repairs, and four had not undergone surgery because of their clinical status. All patients had already undergone multiple percutaneous balloon dilations without success. Stents were placed percutaneously, through a transhepatic approach, without complications. Adequate caliber of the strictured segment, stable relief of symptoms, and normalization of liver function tests were achieved in 14 patients (82.4%). Partial primary success was obtained in one patient; initial success was achieved in two patients, but strictures recurred after 5 months. The average follow-up period was 8 months. Results suggest that placement of these stents might represent a permanent therapeutic solution for intractable recurrences. Extended follow-up and experimental studies to clarify long-term patency and biotolerance are needed.
