Abstract

Background

Common bile duct (CBD) dilation is typically an indication for intraoperative cholangiogram (IOC). We hypothesized that isolated CBD dilation on pre-operative ultrasound (US) is not predictive of choledocholithiasis (CD) on IOC.

Methods

A retrospective study comparing patients with dilated versus normal CBD diameter on pre-operative US. CBD dilation on pre-operative ultrasound was defined as ≥ 0.6 cm, with 1 mm added per decade of life above 60-years-old. Demographics, laboratory values, CBD diameter, cholecystitis grades, and clinical outcomes were collected.

Results

341 patients underwent LC with IOC during the study period, of which 46 patients had isolated CBD dilation. CBD dilation via ultrasound had a sensitivity of 80.00 %, specificity of 25.49 %, positive predictive value of 17.39 %, and negative predictive value of 86.67 %. There was no difference in demographics, cholecystitis severity, complication or readmission rates.

Conclusion

Isolated CBD dilation does not present an increased risk of CD compared to normal CBD diameter.

术前超声检查孤立的胆总管扩张不能作为术中胆管造影检查胆总管结石的预测指标

背景：胆总管（CBD）扩张是术中胆管造影（IOC）的典型指征。我们假设术前超声（US）孤立的CBD扩张不能预测IOC患者胆总管结石（CD）。方法采用回顾性研究方法，比较术前CBD直径扩大与正常患者的超声心动图。术前超声定义CBD扩张≥0.6 cm， 60岁以上每10年增加1 mm。收集人口统计学、实验室值、CBD直径、胆囊炎分级和临床结果。结果341例患者在研究期间接受了LC合并IOC，其中46例患者有孤立性CBD扩张。超声诊断CBD扩张的敏感性为80.00 %，特异性为25.49%，阳性预测值为17.39%，阴性预测值为86.67%。在人口统计学、胆囊炎严重程度、并发症或再入院率方面没有差异。结论：与正常CBD直径相比，孤立的CBD扩张不会增加CD的风险。
