Abstract
Sauer, R., Fahrländer, H. & Fridrich, R. 1973. Comparison of the Accuracy of Liver Scans and Peritoneoscopy in Benign and Malignant Primary and Metastatic Tumours of the Liver. 222 Confirmed Cases Examined by Both Methods Simultaneously. Scand. J. Gastroent. 8, 389-394. The accuracy of liver scanning and peritoneoscopy was compared in 123 patients with primary or metastatic liver tumours, including a few benign localized lesions and in 99 patients without such lesions. All findings were histologically verified by biopsy, operation, or necropsy. Using only one method, the incidence of false negative findings was 20% for both. False positive findings were 18 % for liver scans and absent for peritoneoscopy supplemented by target biopsy. The incidence of false negative findings was reduced to 7 % and false positive results could be eliminated by using both methods together. Thus the liver scan and peritoneoscopy should be used combined to document space-occupying lesions of the liver. Liver scanning can differentiate cirrhosis from neoplastic liver disease.
