title: The role of HIDA scanning in the assessment of external biliary fistulae.
abstract: Three patients with postoperative external biliary fistula are described. In each, radionuclide 99Tcm HIDA was used to define the anatomy of the fistula. The extent of the fistula and the presence of distal obstruction to bile flow could also be determined. This information was used to predict the likelihood of spontaneous fistula closure. HIDA scanning is a useful noninvasive alternative to other investigations, such as fistulography and cholangiography, which do not always provide useful information. The results of HIDA scanning can aid the clinical decision on the need for surgical intervention to correct an external biliary fistula.
