Abstract
The paper on hand reports on preliminary results obtained by applying the diagnostic expert system CADIAG-2 in the area of gallbladder and biliary tract diseases. The study included 71 clinical cases from a university hospital. 32 of them were multi-problem cases. The cases were tested retrospectively. The accuracy of CADIAG-2's results was determined by comparing the computer diagnoses with the clinically or, if available, anatomic-pathologically confirmed diagnoses. A total accuracy of about 90% could be reached, where the respective evaluation criterion was whether the gold standard diagnosis was either confirmed by CADIAG-2 or established as a diagnostic hypothesis at the first, second, or third place in the ranked list of proposed hypotheses. In the multi-problem cases, all discharge diagnoses were tested and evaluated separately.
