REMNANT CYSTIC DUCT IN T-TUBE CHOLANGIOGRAPHY

Abstract
An analysis of 70 postoperative T-tube cholangiograms is described. Our findings indicate: 1. Cystic ducts are just as likely to be left incompletely excised whether they are angular or parallel in type. Significantly longer remnants, however, are left in the parallel group. 2. Application of cholangiographic techniques in the operating room similar to those presently available in the postoperative setting will undoubtedly reduce the over-all incidence of remnants as well as the mean lengths of those which cannot be excised completely. 3. A medially running remnant is much more intimately associated with a common hepatic duct than other types. Although such a remnant is frequently difficult and in some instances impossible to resect, it probably also causes extrahepatic obstruction early with only minimal dilatation.
