Efficacy of hepatobiliary scintigraphy in demonstrating cholangio-colic fistulae. Is formation of internal biliary fistula related to external leak closure?
ABSTRACT The authors present four cases of internal biliary fistulae (IBF) identified on hepatobiliary scintigraphy. All of the cases share common history of external biliary leak closure. Scintigraphy in all four cases showed a similar pattern of direct visualization of transverse colon without any significant small bowel activity. This suggests an increased frequency of IBF formation in cases with external fistulous tract closure. Retrospectively, it appears that spontaneous closure of external leak may be pathological consequence of formation of IBF involving hepatic flexure.

ABSTRACT: The recently acquired ability to tag 99mTc to a number of chemicals which are excreted avidly by the liver and concentrated in the gallbladder has enabled improved diagnosis of acute cholecystitis. This article gives a brief overview of the imaging technique.Australian family physician 07/1984; 13(6):420. · 0.67 Impact Factor
