OBJECTIVE
To determine the influence of biliary drainage catheter placement on bile duct wall thickness, we performed intraductal ultrasonography (IDUS) in patients before and after biliary drainage.
METHODS
Patients underwent IDUS before and after either short-term (n = 9, 6 to 8 days) or long-term (n = 9, 14 to 35 days) biliary drainage using a thin (2.0 mm diameter), 20 MHz probe inserted by means of a transpapillary route or a percutaneous tract. The bile duct wall thickness (mean +/- standard deviation) was retrospectively measured at the upper portion of the common hepatic duct.
RESULTS
The bile duct wall thickness increased from 0.8+/-0.4 mm (predrainage) to 2.0+/-1.6 mm (post-drainage) in the long-term group (p < 0.001) but was not significantly increased in the short-term group.
CONCLUSIONS
The bile duct wall thickness as measured on IDUS appears to be increased after placement of biliary drainage catheters.
目的
为了确定胆管引流导管置入对胆管壁厚度的影响，我们在胆管引流前后对患者进行了导管内超声检查（IDUS）。
方法
患者在使用细（直径2.0mm）、20MHz探头通过经乳头途径或经皮通道进行短期（n = 9，6至8天）或长期（n = 9，14至35天）胆管引流前后接受IDUS检查。通过回顾性分析，在肝总管上部测量胆管壁厚度（平均值±标准差）。
结果
长期组胆管壁厚度从引流前的0.8±0.4mm增加至引流后的2.0±1.6mm（p < 0.001），而短期组无显著增加。
结论
IDUS测量的胆管壁厚度在胆管引流导管置入后似乎会增加。
