Benign biliary strictures are usually treated surgically or endoscopically. When these strictures are not accessible by endoscope or when open repair is not possible, percutaneous dilatation treatment is indicated. The efficacy of treatment is usually evaluated by clinical trial which includes leaving a small non-functional catheter in situ and following liver function tests. The evaluation may be effectively done by the biliary manometric perfusion test.
The aim of this paper is to emphasize the importance of percutaneous dilatation treatment of benign biliary strictures with focus on the role of the biliary manometric perfusion test and its future prospects.
Based on the literature and our own experience, this article gives a short overview of percutaneous treatment of benign biliary strictures, indications, techniques, complications and results. The treatment of these strictures has an overall success rate between 60 to 90%. This article also explains the biliary manometric test, the technique and its importance in evaluation of treatment success.
Benign biliary strictures of the hepatic duct junction or bilio-enteric anastomosis are difficult to treat surgically and are endoscopically inaccessible. Percutaneous treatment by balloon dilatation and long term external-internal drainage is feasible in the majority of these patients. It is minimally invasive, safe and effective. The evaluation of the treatment success may be more effectively done by the manometric perfusion test. It is easy, reliable, less time-consuming giving immediate results, and relatively safe.
良性胆管狭窄通常采用手术或内镜治疗。当这些狭窄无法通过内镜处理或无法进行开放修复时，需进行经皮扩张治疗。治疗效果通常通过临床试验评估，包括留置一根小的无功能导管并跟踪肝功能测试。通过胆管测压灌注试验可有效进行评估。
本文旨在强调经皮扩张治疗良性胆管狭窄的重要性，重点关注胆管测压灌注试验的作用及其未来前景。
基于文献和我们自己的经验，本文简要概述了良性胆管狭窄的经皮治疗、适应证、技术、并发症及结果。这些狭窄的治疗总体成功率在60%至90%之间。本文还解释了胆管测压试验、技术及其在评估治疗成功方面的重要性。
肝管交界处或胆肠吻合口的良性胆管狭窄手术治疗困难且内镜无法处理。在大多数此类患者中，通过球囊扩张和长期内外引流进行经皮治疗是可行的。它微创、安全且有效。通过测压灌注试验可更有效地评估治疗成功与否。该试验简便、可靠、耗时少且能立即得出结果，相对安全。
