Abstract
: We performed a retrospective study on 163 patients for evaluation of the benefit of intravenous cholangiography prior to laparoscopic cholecystectomy. Radiographic evaluation of the various areas of the biliary system was classified regarding resolution of anatomic structures: well detailed (excellent), impaired image but reliable interpretation possible (good), insufficient contrast with limited assessment (poor), no reliable judgment possible (insufficient). The common bile duct could be described as “good” in 96.3%, whereas the cystic duct could be described as “good” in only 54.6%. Concrements of the gallbladder were recognized in 72.4%, and common bile duct stones were diagnosed in only two of three patients. A distal junction of the cystic duct was found in nine cases, but there was no influence on the following operative procedure. Only one of two patients with a short cystic duct was identified. We found no improvement after routine use of intravenous cholangiography concerning the evidence of common bile duct stones or the avoidance of lesions of the common bile duct. Hence routine use of intravenous cholangiography prior to laparoscopic cholecystectomy is not justified.
