Abstract

Purpose

This study aimed to examine the correlation between right posteroinferior bile duct (RPBD) angulation and the occurrence of bile duct stones in patients with hepatolithiasis.

Methods

Patients presenting with hepatolithiasis in our hospital from January 2011 to July 2016 were divided into two groups according to whether their RPBD was affected by stones. A statistical analysis for the relevant factors associated with bile duct stone formation in the RPBD was performed.

Results

The binary logistic regression results showed that stenosis of the right hepatic duct [odds ratio (OR): 7.313; 95% confidence interval (CI) 4.131–12.945)] and the angle of the RPBD (OR 0.896; 95%CI 0.877–0.916) were risk factors associated with the formation of RPBD stones. Further, the receiver operating characteristic curve indicated that, when the angle of the RPBD was less than 44.58°, stones were able to form more easily in the RPBD.

Conclusion

The occurrence of bile duct stones is well correlated with sharp bile duct angulation.

肝内胆管结石患者右后下胆管成角与胆管结石发生相关。

摘要

目的

本研究旨在探讨右后下胆管 (RPBD) 成角与肝内胆管结石患者胆管结石发生之间的相关性。

方法

将2011年1月至2016年7月在我院就诊的肝内胆管结石患者根据其RPBD是否受结石影响分为两组。对与 RPBD 中胆管结石形成相关的相关因素进行了统计分析。

结果

二元logistic回归结果显示右肝管狭窄[比值比(OR):7.313;95% 置信区间 (CI) 4.131–12.945)] 和 RPBD 的角度(OR 0.896;95%CI 0.877–0.916)是与 RPBD 结石形成相关的危险因素。此外,受试者工作特征曲线表明,当 RPBD 的角度小于 44.58°时,RPBD 中更容易形成结石。

结论

胆管结石的发生与胆管成角明显相关。
