  • Title: Ultrasonography and hepatobiliary scintigraphy in the assessment of biliary-enteric anastomoses.
    Author: Zeman RK, Lee C, Stahl RS, Cahow CE, Viscomi GN, Neumann RD, Gold JA, Burrell MI.
    Journal: Radiology; 1982 Oct; 145(1):109-15. PubMed ID: 6812157.
    Abstract:
    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.
