[Accuracy of ultrasonics in gallbladder diseases (author's transl)].

Report on 158 ultrasonics findings of gallbladder diseases, all of them controlled by laparotomy. The diagnostic accuracy for stones was 99.3% with one false-positive but without any false-negative result. Because ultrasonics is a less time consuming and inexpensive method without trouble for patients, it should be used - if possible with a real-time equipment - as the first apparatively-diagnostic procedure in cases of suspected gallbladder diseases.
