Twenty-three patients with surgical diversion of the biliary tract were serially studied with ultrasonography and hepatobiliary scintigraphy using 99mTc-HIDA or 99mTc-disofenin. Refluxed biliary air resulted in nondiagnostic sonograms in 14% of cases. Persistent postoperative dilatation was present in five patients (22%). Scintigraphy allowed differentiation of biliary dilatation with obstruction from nonobstructed dilatation. By coordinating the noninvasive imaging results, those patients requiring study using direct injection of contrast material may be selected.
对23例接受胆道手术改道的患者，使用99mTc - HIDA或99mTc - 二乙三胺五乙酸（disofenin）通过超声检查和肝胆闪烁扫描进行了系列研究。14%的病例中，反流性胆系积气导致超声检查结果无法诊断。5例患者（22%）术后存在持续性扩张。闪烁扫描可区分梗阻性胆管扩张和非梗阻性扩张。通过整合非侵入性成像结果，可选择那些需要通过直接注射造影剂进行检查的患者。
