A comparison of the accuracy of peritoneoscopy and liver biopsy in the diagnosis of cirrhosis.

The accuracy of peritoneoscopy and liver biopsy in the diagnosis of hepatic cirrhosis was compared in 473 consecutive patients submitted to both procedures. One hundred and fifty-two of them had cirrhosis diagnosed by one or both methods. There was 73% agreement between the two procedures. ;Apparent' false-negative results were 17.7% for peritoneoscopy and 9.3% for liver biopsy. The incidence of false-negative results in the diagnosis of cirrhosis can be reduced by combining both procedures.
