To evaluate the results of percutaneous balloon dilation of benign bile duct strictures in a series of patients with a long follow-up period.
56 patients with benign bile duct strictures underwent balloon catheter dilation. These patients had strictures of various origins: postsurgical, postlocal not surgical treatments, associated with gallstones, due to primary sclerosing cholangitis and to Mirizzi's syndrome. In 41 cases the diagnosis was made on the basis of radiological findings and history and in 15 cases on the basis of transluminal biopsy.
In 87.5% of cases the treatment was immediately successful. There were no early recurrences, but 7 (21%) recurrences were seen over 1 year after treatment; of these, 57% underwent another balloon dilation procedure with a positive long-term outcome.
The long-term success rate obtained in 72% of this series confirms that percutaneous bile duct dilation is a valid alternative to surgery without being burdened by complications; the procedure is also a valid alternative to the approach using endoscopic stents.
评估一系列长期随访患者中经皮气囊扩张治疗良性胆管狭窄的结果。
56例良性胆管狭窄患者接受了气囊导管扩张治疗。这些患者的狭窄病因各异：术后、局部非手术治疗后、与胆结石相关、原发性硬化性胆管炎以及Mirizzi综合征所致。41例根据影像学检查结果和病史做出诊断，15例根据腔内活检做出诊断。
87.5%的病例治疗即刻成功。无早期复发，但治疗后1年以上出现7例（21%）复发；其中，57%的患者接受了另一次气囊扩张手术，长期效果良好。
本系列72%的长期成功率证实，经皮胆管扩张术是一种有效的手术替代方法，且无并发症负担；该方法也是使用内镜支架治疗方法的有效替代方案。
