The laparoscopic ultrasound (US) probe provides a new modality for evaluating biliary anatomy during laparoscopic cholecystectomy (LC).
We performed a laparoscopic US examination in 65 patients without suspected common bile duct (CBD) stones prior to the performance of a laparoscopic cholangiogram (IOC). We then compared the cost, time required, surgeon's assessment of difficulty, and interpretations of findings.
There was a significant difference in the cost of US versus the cost of IOC ($362 +/- 12 versus $665 +/- 12; p < 0.05). Surgeons who had performed >10 US (EXP) were compared with those who had performed </=10 (NOV). There were significant differences between the EXP and NOV groups in ease of examination, visualization of biliary anatomy, and accuracy of measurement of the CBD.
The use of laparoscopic US for the accurate evaluation of the CBD and biliary anatomy requires that the surgeon has surpassed the learning curve, which we have defined as having performed >10 US exams.
腹腔镜超声（US）探头为腹腔镜胆囊切除术（LC）期间评估胆道解剖结构提供了一种新方法。
在进行腹腔镜胆管造影（IOC）之前，我们对65例无胆总管（CBD）结石可疑的患者进行了腹腔镜超声检查。然后我们比较了费用、所需时间、外科医生对难度的评估以及检查结果的解读。
超声检查费用与IOC费用存在显著差异（362±12美元对665±12美元；p<0.05）。将进行过超过10次超声检查（EXP）的外科医生与进行过≤10次超声检查（NOV）的外科医生进行比较。EXP组和NOV组在检查的难易程度、胆道解剖结构的可视化以及CBD测量的准确性方面存在显著差异。
使用腹腔镜超声准确评估CBD和胆道解剖结构要求外科医生已越过学习曲线，我们将其定义为已进行超过10次超声检查。
