Cholescintigraphy and Biochemical Tests in Cholecystitis - An Evaluation with Discriminant Analysis

Summary

The biochemical values of 76 patients with suspected cholecystitis were subjected to discriminant analysis. The final diagnoses, i. e. acute cholecystitis, chronic cholecystitis and non-biliary disease, were used as the grouping variable. Cholescintigraphy identified patients with acute cholecystitis. Routine preoperative biochemical tests were found to be of limited value. Only alkaline phosphatase was of help in predicting common-duct stones, especially in patients with acute cholecystitis. The conclusion is that many biochemical tests presently in common use could as well be dispensed with.

Die biochemischen Werte von 76 Patienten mit Verdacht auf Cholezystitis wurden einer Diskriminantenanalyse unterworfen. Die endgültige Diagnose (akute Cholezystitis, chronische Cholezystitis und nichtbiliäre Erkrankung) wurde als Gruppenvariable eingesetzt. Die hepatobiliäre Szintigraphie selektierte Patienten mit akuter Cholezystitis. Präoperative Routinelabortests waren nur von beschränktem Wert. Nur die alkalische Phosphatase war bei der Voraussage von Steinen im Ductus choledochus hilfreich, insbesondere bei Patienten mit akuter Cholezystitis. Die Schlußfolgerung lautet, daß viele üblicherweise angewandte Labortests ebensogut unterlassen werden können.
