[Sonography as the basic diagnostic method in cholelithiasis].

Abstract

The author analyzes a group of 200 patients who all were indicated for operation of the gallbladder, based on ultrasonic and radiological preoperative diagnostic examinations. He draws attention to the great diagnostic accuracy of sonography, which was 96.5% in his group. Radiological methods are of equal accuracy but have a number of disadvantages. The diagnostic accuracy is enhanced by mutual combination of the two methods in controversial cases. The author concludes from his work that sonography ought to be the primary examination when disease of the gallbladder is suspected. Classical radiological methods should be a supplementary method which increases the diagnostic accuracy of biliary disease and thus reduces to a minimum incorrectly indicated surgical revisions.
