In this monograph, the author inclusively summarizes his extensive experience with intravenous cholangiography over the past five years at the Lahey Clinic and the New England Baptist Hospital. The major contribution of this text resides in the emphasis on the time-density-retention concept elaborated in an earlier report by the author. With this scheme, one can evaluate the presence or absence of relative obstruction of the common bile duct, when either the gallbladder has been removed or the cystic duct occluded. This is accomplished by comparing the density of contrast material in the common duct at 60 and 120 min postinjection. If the density continues to increase beyond 60 min, the inference is partial common duct obstruction. Considerable roentgenographic evidence is advanced to refute the concept that the common duct dilates in the postcholecystectomy patient in the absence of obstructive disease of this structure.
The text reflects favorably the author's exhaustive
