| Popis: | The effect of etiology on findings in cholescintigraphy in patients with extrahepatic obstruction was retrospectively evaluated in 29 patients. Of 11 patients with obstruction secondary to cancer, seven (78%) of nine had complete obstruction (delayed images were not obtained in two) and nine (82%) of 11 had a moderate to severe decreases in hepatocyte clearance. Of 12 patients with obstruction secondary to cholelithiasis, only four (36%) had complete obstruction (delayed images were not obtained in one) (p less than 0.05) and all 11 had normal or only midly decreased hepatocyte clearance (p less than 0.05). All five patients with obstruction secondary to pancreatitis had mild partial obstruction and normal or mildly decreased hepatocyte clearance. One patient had partial obstruction secondary to an abscess adjacent to the common bile duct; hepatocyte clearance was mildly decreased. Cancerous and noncancerous causes of biliary tract obstruction produce significantly different findings in hepatobiliary imaging. |
