One hundred twenty-two consecutive patients who had hepato-iminodiacetic acid (HIDA) scans over a 5-month period were reviewed. These scans were found to have 94% sensitivity, but only 36% specificity for correctly diagnosing pathological variants of cholecystitis. Frequently, HIDA scans were misinterpreted to show common bile duct obstruction (CBDO); only 20% of cases of CBDO suggested on HIDA could be confirmed surgically. Sonography gave 88% to 90% sensitivity and 91% specificity in correctly diagnosing pathological variants of cholecystitis and correctly demonstrated CBDO in 80% of the cases. As first-line studies to evaluate biliary tract disease, HIDA scans are costly and should be eliminated.
回顾了在5个月期间连续进行肝亚氨基二乙酸(HIDA)扫描的122例患者。这些扫描对胆囊炎病理变异的正确诊断敏感性为94%,但特异性仅为36%。HIDA扫描经常被误判为显示胆总管梗阻(CBDO);HIDA提示的CBDO病例中只有20%能通过手术得到证实。超声检查对胆囊炎病理变异的正确诊断敏感性为88%至90%,特异性为91%,并在80%的病例中正确显示了CBDO。作为评估胆道疾病的一线检查,HIDA扫描成本高昂,应该摒弃。
