Angiocholographie intra-veineuse et cholangiographie rétrograde : rendement diagnostique individuel et cumulatif chez 170 patients
Intravenous and endoscopic retrograde cholangiography. individual and cumulative diagnostic yields in 170 patients
One hundred and seventy patients complaining of symptoms suggestive of biliary tract disease had been evaluated by means of both intravenous and endoscopie retrograde cholangiography. The radiological series were reviewed by a staff radiologist and a gastroenterologist altogether and the data were drawn as to the rate of inadequate intravenous studies (22.35 %) and of unsuccessful endoscopie retrograde examinations (10.58 %). Sensitivity, specificity and predictive values of the two techniques were also analyzed, limited to patients with surgical verification of diagnosis. Endoscopie cholangiography gave a far better yield either in obstructive (stones, strictures) and in nonobstructive (fistulas, sump syndrome, extrinsic compression) diseases of the biliary tract. It is concluded that intravenous cholangiography is an unrewarding technique because of both a high rate of inadequate studies and a low diagnostic accuracy. Therefore, this study should be routinely replaced by the endoscopie technique irrespective of the presence or absence of jaundice.
