Fine needle cholangiography in postcholecystectomy patients

Thirteen cholecystectomized patients with postcholecystectomy symptoms are described. The patients were investigated with a combination of intravenous cholangiography and fine needle cholangiography. Fine needle cholangiography was found useful in patients with nonvisualized or questionably abnormal bile ducts on intravenous cholangiography. In one patient the intravenous cholangiogram was normal, but percutaneous cholangiography demonstrated calculi.
