Right upper quadrant and epigastric abdominal pain are common presenting complaints in the emergency department. With increasing access to point-of-care ultrasound, emergency physicians now have an added tool to help identify biliary problems as a cause of a patient's right upper quadrant pain. Point-of-care ultrasound has a sensitivity of 89.8% (95% CI 86.4-92.5%) and specificity of 88.0% (83.7-91.4%) for cholelithiasis, very similar to radiology-performed ultrasonography. In addition to assessment for cholelithiasis and cholecystitis, point-of-care ultrasound can help emergency physicians to determine whether the biliary system is the source of infection in patients with suspected sepsis. Use of point-of-care ultrasound for the assessment of the biliary system has resulted in more rapid diagnosis, decreasing costs, and shorter emergency department length of stay.
右上腹和上腹部疼痛是急诊科常见的就诊主诉。随着即时超声检查的普及，急诊医生现在有了一项额外的工具，有助于将胆道问题识别为患者右上腹疼痛的病因。即时超声检查对胆结石的敏感性为89.8%（95%置信区间86.4 - 92.5%），特异性为88.0%（83.7 - 91.4%），与放射科进行的超声检查非常相似。除了评估胆结石和胆囊炎外，即时超声检查还可以帮助急诊医生确定在疑似脓毒症患者中，胆道系统是否为感染源。使用即时超声检查评估胆道系统已实现更快速的诊断、降低成本并缩短急诊科住院时间。
