We evaluated real-time ultrasonography carried out by gastroenterologists for its diagnostic accuracy in 89 patients with obstructive jaundice. The positive predictive values for the site and nature of the obstruction were 94.3 and 89.9%, respectively. The advanced stage of disease in our patients and the clinical background of the investigators may have contributed to the high diagnostic accuracy of ultrasonography in this study. Nevertheless, we recommend that gastroenterologists themselves perform bedside ultrasonography for a definitive diagnosis in patients with obstructive jaundice. The high degree of precision achieved by ultrasound in our setting makes more expensive investigations unnecessary as routine procedures.
我们评估了胃肠病学家进行的实时超声检查对89例梗阻性黄疸患者的诊断准确性。对梗阻部位和性质的阳性预测值分别为94.3%和89.9%。本研究中患者的疾病晚期阶段以及研究者的临床背景可能促成了超声检查的高诊断准确性。尽管如此，我们建议胃肠病学家亲自进行床边超声检查以对梗阻性黄疸患者做出明确诊断。在我们的研究环境中超声检查所达到的高精度使得作为常规程序进行更昂贵的检查变得不必要。
