Preoperative diagnosis and its effect on the treatment of carcinoma of the gallbladder.
In 19 patients with carcinoma of the gallbladder treated over a four year period, several features of percutaneous transhepatic cholangiography have been recognized which have increasingly provided an accurate diagnosis preoperatively. These features are due to intrahepatic invasion of the bile duct and by providing a diagnosis preoperatively can have a large bearing on the choice of therapy for a particular patient. The relative roles of surgical bypass and endoscopically or percutaneously placed prostheses are discussed.

The role of HIDA scanning in the assessment of external biliary fistulae.
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.
