The diagnostic proof of vesico--enteral fistulas is necessary before proceeding to surgical treatment. The detection, however, can often be difficult because of nonspecific symptoms and unreliable uro-radiologic and endoscopic investigations. Additional and more sensitive diagnostic procedures are evaluated like computer tomography, the simple Bourne-test and a radioisotopic test.

Massive lower gastrointestinal (GI) bleeding caused by gallbladder carcinoma eroding into the colonic wall was demonstrated accurately by Tc-99m RBCs. In addition, retrograde bleeding into the gallbladder was also identified while arteriography did not show contrast extravasation. This case supports the use of Tc-99m RBCs over Tc-99m sulfur colloid for more accurate localization of lower GI bleeding.

The use of scintigraphic imaging in the evaluation of gastrointestinal (GI) hemorrhage has been established recently as a screening procedure prior to anigography. We report an unusual and previously unreported cause of acute GI bleeding which illustrates several technical factors to be considered during scintigraphic evaluation of GI bleeding.

The diagnosis of a cholecystocolic fistula has often presented a dilemma to the practicing physician. Routine imaging modalities to confirm this diagnosis have not proven extremely successful. The presence of a small fistulous tract from the gallbladder to the colon is often difficult to demonstrate radiographically. However, with the advent of the newer hepatobiliary radioisotopic scanning agents, the ability to visualize the intrahepatic and extrahepatic bile ducts as well as the presence of the intestinal activity of the radiotracers has improved considerably. The authors present a case of cholecystocolic fistula that was adequately demonstrated with a Tc-99m-PIPIDA hepatobiliary scan. This article is the first to report demonstration of this type of fistula with hepatobiliary scanning.
